Hybrid Pharmacophores as Anti-inflammatory Agents

Hybrid Pharmacophores as Anti-inflammatory Agents CHAPTER VII SUMMARY AND CONCLUSION The Synthesis of molecules that are important in the control of ageing diseases is very important in the present decades. The compounds like Diarylsulfonylurea-chalcone may act as anti-inflammatory agents that may be linked as network to several diseases. The synthetic compounds have the abilities to act as preventive compounds having therapeutic action. In the present decade, one can consider synthetic products in preventing aging diseases via anti-inflammation. Hence there is a need to discover novel synthetic compounds that are deemed in prevention and treatment of diseases showing tremendous impact on health care systems. As a part of our research program aimed at search for new hybrid pharmacophores as anti-inflammatory agents, we are interested to have ÃŽ ±,ÃŽ ²-unsaturatedketone linker to the diarylsulfonylurea basic nucleus to give a series of diarylsulfonylurea-chalcone hybrids. Therefore, in the present study an attempt has been made to design, synthesize and characterize some new diarylsulfonylurea-chalcone hybrids. Drug Discovery and drug development is a knowledge base, expensive and time intense method. Scientific advancements throughout the past 20 years have modified the manner pharmaceutical analysis generate novel bioactive molecules. Advances in machine/computer aided techniques and in parallel support of hardware have enabled in silico strategies, and particularly structure-based drug style technique, to speed up new target choice through identification of hits for the optimization of lead compounds within the drug discovery method. Genomics, proteomics, bioinformatics and, chemo informatics have gained vast quality Associate in development became an integral a part of the commercial and educational analysis, directive drug style and discovery. Virtual screening emerged as a crucial tool in our quest to access novel drug like compounds (Wermuth et al., 1998, Allen, 2002). Rational in silico drug style are often tired 2 ways in which ligand-based or structure-based are analyzed for compound activity. With the supply of the 3D structure of a biological target, its possible to use a structure-based approach to judge and predict the binding mode of a matter inside the situation of the receptor with tying up strategies. Currently it’s a well-liked technique used for increasing the speed of drug coming up with method. This was created attainable by the supply of the many super molecule structures that helped in developing tools to know the structure operate relationships, machine-controlled tying up and virtual screening. Moreover, once no 3D structural data regarding target proteins with their receptor website is obtainable ligand-based style is applied. The ligand-based approach starts with a bunch of ligands binding to a similar receptor with a similar mechanism. These four completely different methods supported the previous information of the tar gets 3D structure and therefore the ligands binding to that square measure predominant (Van, 2007; Kier, 1967). Chalcones are considered as precursors of flavonoidsand isoflavonoids in edible plants thatshowa variousarray ofmedical specialtyactivities. Chalcones are new class of glycosidase (ÃŽ ±-amylase, ÃŽ ±-glucosidase, and ÃŽ ²-amylase) inhibitors that shows non-competitive inhibition acts against ÃŽ ±-glucosidase. The effect of chalcones in hyperglycemic-normal rats on serum glucose-lowering properties highlighting the novel compounds showing strong anti-hyperglycemic properties (Damazio et al., 2009). Sulfonylureas were only drugs used to stimulate the insulin secretion in patients with type 2 diabetes or D2M. Diarylsulfonylurea (DSU) is a novel anticancer molecule because has unique chemical structure with broad-spectrum antisolid-tumor activity in preclinical models. The sulfonylurea inhibits the eosinophil survival in a method similar to lidocaine. Anti-inflammation is the biological process of the diseases that links to the pathways related to aging diseases. A substance that reduces inflammation are linked to cancer, diabetes, etc., are anti-inflammatory compounds used to reduce the risk of age related diseases. In the present investigation, the LPID approach is now applied to the database of 25 compounds virtually designed for finding ‘best fit’ (hit identification) against selected anti-inflammatory protein drug target (5-Lipoxygenase (5-LO)). The compounds appear out of these molecular docking studies with least binding energy against target protein were prepared by using standard conventional methods of synthesis and subjected for corresponding in vitro and in vivo studies. By this means, it is possible to understand how the compounds interact with the selected anti-inflammatory target protein. The results promising out of this study can be used to identify a new class of potential anti-inflammatory agents with selective 5-LO inhibitory activity. A set of 25 diarylsulfonylurea-chalcone hybrids 4a-4y were subjected to ligand-protein inverse docking simulation using software Molegro Virtual Docker v 5.0. These compounds were docked against selected anti-inflammatory drug target (i.e. Human 5-Lipoxygenase PDB Code: 3V99). The results of these studies could help in preliminary confirmation of inhibitory activity against 5-lipoxygenase. The result of the docking interactions between the selected compounds and protein target, data in shows that compound 4g was accomplished best binding efficiency against 5-lipoxygenase with Moldock Score (-193.641) with 3 hydrogen bond interactions and the corresponding interacting residues are Asn 554, Ser 608 and Ala 606 these hydrogen bonds not only relevant for the binding 4g to 3V99 to exhibit highly selective and potent binding affinity. Moreover, from the data given in it appears that the co-crystallized ligand arachidonic acid and positive standard abietic acid showed no hydrogen bond inter actions with the active binding site residues indicating the importance of steric interactions and electrostatic interactions for their observed 5-lipoxygenase inhibitory activity. The key intermediary in the current study 1-(3-acetylphenyl)-3-tosylurea was synthesized by reaction of 3-aminoacetophenone with methylchloroformate under basic conditions at 0 Â °C temperature to give methyl-3-acetylphenylcarbamate followed by the reaction with toluene sulphonamide and on the other hand subsequent Claisen-Schmidt condensation of the intermediate with appropriate aromatic/heteroaromatic aldehydes in ethanolic KOH solution to give the corresponding diarylsulfonylurea-chalcone hybrids (4a4y) in good yield The investigation of the compounds(4a-4y) in vitro 5-LO inhibitory activity screening data revealed that the compounds 4r and 4o demonstrated comparatively the most potent inhibitory activity, with IC50 values of 7.88Â ±0.14 Â µg/mL and 11.77Â ±0.21 Â µg/mL, respectively. An in silico toxicity tests can be conducted for diarylsulfonylurea-chalcone hybrids 4o, 4q, 4r, 4t, 4y and standard (Aceclofenac) to predict the toxicity nature using Lazar server. All the compounds are predicted as non-toxic. From the in vitro 5-LO inhibitory activity data, five potent diarylsulfonylurea-chalcone hybrids compounds (mentioned above) which displayed significant activity has been selected for further anti-inflammatory activity studies by using in vivo bioassay model i.e. Carrageenan-induced rat paw oedema method. The results of the assessment have been viewed by taking Aceclofenac as the standard drug. Finally the work concludes that all the compounds displayed were shown remarkable anti-inflammatory activity.

Compare ‘The Soldier’ written by Rupert Brooke and ‘Anthem for Doomed Youth’ written by Wilfred Owen

Lately we have studied two poems that were written during the time of World War One. They were ‘The Soldier' written by Rupert Brooke and ‘Anthem for Doomed Youth' written by Wilfred Owen. Both of these poets were soldiers involved in fighting during World War One. ‘The Soldier' is an uplifting and optimistic poem looking at the positive side of dying for your country when going to war. I think the poet Rupert Brooke wrote the poem to send home to his family to reassure them if he died it would be peacefully and not in pain. In the first stanza Brooke is saying that if he dies while away in this foreign country, that he'll leave a part of England there. The following quotation is an example that he is English through-and-through: â€Å"A dust whom England bore, shaped, made aware, Gave, once, her flowers to love, her ways to roam.† He was born and brought up with a certain kind of English lifestyle and culture. He then goes on to describe the flowers and winding paths making us think of England as idyllic and peaceful. He uses personification in the first line of the quote. It compares England to a woman giving birth to a child and bringing it up. In the second stanza Brooke describes England as a country of no evil and that he will remember it forever, he'll always have happy memories from the past when he lived in England. Some of the best memories being times he's spent with the people he loved. The final line in stanza two is: â€Å"In hearts at peace, under an English heaven.† This conveys that England has shaped him into who he is and he is proud of it. ‘The Soldier' is a sonnet. A sonnet is a 14-line poem used to express personal feelings. His choice of words describe his personal feelings as well. These words all add reassurance to the poet's relatives that if he dies, it will be peaceful. Examples of the words used to describe the peacefulness are: â€Å"blest, dream, gentleness, peace and heaven†. One of the main features that the poet uses in this in this poem is repetition. The most widely used word that the poet uses repeatedly is ‘England' and ‘English' adding to the patriotism and significance that England has to him it isn't just a place it represents a culture and a set of values as well. The structure of the poem is that it has two verses and 14 lines in total. The rhyming scheme is- A B A B C D C D – E F G E F G Each letter represents a line, two lines with the same letter means that it rhymes. Brooke uses alliteration, the consonant that is being repeated is an ‘f', it is a soft sound yet again showing calmness and peacefulness: â€Å"That there's some corner of a foreign field That is forever England.† Other alliteration such as: â€Å"Her sights and sounds†, â€Å"Dream happy as day†, And, laughter, learnt of friends†. All these show how the poet feels about the possibility of his death. He is optimistic and knows he is prepared to die fighting for his country. The other poem ‘Anthem for Doomed Youth' written by Wilfred Owen is also a sonnet. ‘Doomed youth' mean all those young men to be sent to war and on the front are destined to die. In the poem the poet expresses his views on what should happen to these people when they die. They all should be given a funeral and a proper send off, even those on the battlefield. You can tell this because throughout the poem he mentions funerals and church services. The first stanza suggests the horror of death and how they compare these men to animals † For those who die as cattle.† There deaths have been brutal and violent. The first stanza demonstrate this, it is full of noise and violence to show the pandemonium of the battle compared to the funeral they would have had at home and how it differs: â€Å"No prayers, bells, nor any voice of mourning save the choirs† The second stanza is more peaceful and shows the grief of the relatives when they find out what's happened and in the second stanza it looks at the kind of send off they would have had if they had been at home. It uses words such as ‘candles', ‘hands of boys', ‘their pall', ‘holy glimmers of goodbyes' and ‘flowers' all things that are related to a church service. The final line of this poem depicts the morning of the soldier's relatives: â€Å"And each slow dusk a drawing-down of blinds.† When a death occurred during this period the families who had lost people they loved, closed the blinds to show their sadness and to keep the rest of the world out. In this case the consonant being repeated is ‘D'. D is a harsh sound stressing the relatives coping with losing a loved one. This poem is also a sonnet it shows personal feeling of what the poet though about not getting a proper send off. The rhyming scheme is- A B A B C D C D – E F F E G G The poem ends with a rhyming couplet that means the last two lines rhyme. In the first stanza the poet uses onomatopoeia to demonstrate the sound on the battlefield: â€Å"Only the stuttering rifles rapid rattle† It is also an example of alliteration. This poem is against war and the inappropriate way these men have lost their lives. The general mood of he poem is anger and sadness. Anger because the young men died unnecessarily without having much of a life and sadness because all these people are dying needlessly and others are mourning because of this. ‘The Soldier' and ‘Anthem for Doomed Youth' are both sonnets with two stanza and 14 lines but both poem are completely different in their take of the same situation.

What is a Story Angle

The angle of a news or feature story is the storys point or theme, most often expressed in the lede of the article. Its the lens through which the writer filters the information he or she has gathered and focuses it to make it meaningful to viewers or readers. Types of Story Angles There may be several different angles to a single news event. For instance, if a new law is passed—whether national or local—angles might include the cost of implementing the law and where the money will come from; the agenda of the lawmakers who authored and pushed for the law; and the impacts of the law on the people most closely affected. The impacts of legislation can range from financial to environmental, short term and long term. While each one of these could be included in one main story, each one also lends itself to a separate and interesting story and depending on the reach of the legislation at hand, each constitutes an angle of its own. Using the inverted-pyramid structure basic to American-style journalism, in which the most important, urgent information is at the top, the reporter threads that angle through the story to tell the reader why it matters to her or to him. Local or National Both news and feature stories can also have angles based on geography and range of readership or viewership, depending on your location and the type of outlet you work for. Examples include the national angle and the local angle: The national angle is taken by national media for major stories, trend pieces, and stories about issues that affect the country as a whole: those are the kinds of stories that fill the front pages of major metropolitan dailies. An example would be the passage of President Barack Obamas Patient Protection and Affordable Care Act and its effect on Americans of different socioeconomic groups on a national scale. Another might be a weather event that strikes a large swath of the country and affects millions of people.The local angle comes when a reporter localizes those stories and focuses on the local or regional impact of those events, making them immediately relevant to the local readers. For example, in the case of a hurricane ravaging shorelines along the East Coast, a news outlet in Florida would focus specifically on the area where its readers or viewers are located. In the case of a law, the paper would assess local impact and reaction. Occasionally the reverse happens—local stories go national—when, for example, an event in a small town is so impactful as to prompt a national look at an issue or the passage of a national bill; or when a case from a lower court in a small town goes to the U.S. Supreme Court, or a soldier from your town testifies before the U.S. Congress. Those events can shine a light on a small locale (and often a local reporter) quite fittingly. Beware to not over-localize: While it is appropriate to focus on the small-town high school attended by a Supreme Court nominee (if interesting), it might be a stretch to make a big deal about the little town where he spent a week in summer camp when he was 5. Again, it depends on whether its interesting and why it matters. Follow-Up Stories Straddling the arc of national and local angles are the good stories that come in the aftermath of a big event—the so-called follow-up stories—when the chaos of breaking news has passed and the effects become clearer and more understandable. Follow-up stories give reporters the opportunity to find and include information that was either not immediately available during the reporting of the event itself or that could not be included for space or time. They also provide the chance to include more background, new details, deeper analysis and perspective, and more in-depth human stories and interviews. Good News Judgment Regardless, whether reporters are covering breaking news or features or covering local or national news, to find a storys meaningful angle—the crux of why it matters or why its interesting—they must cultivate a so-called news sense, or a nose for news: that instinctive feel for what constitutes a good story. It may not always be the most obvious story, and often its not; often it does not even start as a big story, and it may not even be a big story. But hard work and eventually experience will help reporters figure out where a good story begins. To start, it helps to read good literature and good journalism. Emulating experienced reporters who have that feel can help us understand what good story ideas are and why. What do top-notch journalists write about? How do they get their stories and develop them? Who do they talk to? What other journalists do they read? The other key way is to develop contacts in your beat and in your community and to spend time listening to what they have to say. Get out there in the street, the coffee shops, the classrooms, the offices of city hall. Talk to the secretaries, the waitresses, the doormen, and the street cops. Trusting contacts, good questions, and listening are not only the best ways to stay abreast of the news, but they sharpen your ear for good yarns and for what matters to your readers and the community at large.
