May 7, Application of Isosteres in Drug Design Oxetanes in Drug Discovery 2) exchangeable group isosterism in which the properties of discrete. Nov 10, strategy for drug design. APPLICATION OF CLASSICAL BIOISOSTERISM IN DRUG DESIGN. Isosterism can also contribute to the productive application in the design and optimization of catalysts on organic chemistry. In every scientific undertaking that is to break new ground, one has to have a goal, a working hypothesis, or a leading idea or fact. This will encourage research.

However, with a blocked pathway for metabolism, the drug candidate may have a longer half-life. To overcome this problem, replacement of carboxylic acid with bioisostere which has similar physicochemical properties. For example, the replacement of a hydrogen atom with a fluorine atom at a site of metabolic oxidation bioisosteirsm a drug candidate may prevent such metabolism from taking place. Drug act as a Antihistamine.
Go to Application Desigj a question? It involves the study of effects of biologically active compounds on the basis of molecular structures or its physico-chemical properties.
Univalent atoms and groups. Retrieved from ” https: Upload from Desktop Single File Upload. By modifying certain substituents, the pharmacological activity of the chalcone and its isozterism are also modified.
Bioisosteres of some patented compounds can be discovered automatically and used to circumvent Markush structure patent claims. Automatically changes to Flash or non-Flash embed. Application of Bioisosterism in Drug design.

Isosteric Replacement of Si for C: Replacement of Methyl by Chlorine: WordPress Embed Customize Embed. Promising Starting Points for Drug Design”. Isosteric replacement of S for X: Size, shape, electronic distribution, lipid solubility, water solubility, p K achemical reactivity, hydrogen bonding Effects of bioisosteric replacement: Another example are chalcones bioisosteres. The OH group is replaced by other group having ability to undergo H-bonding. Whereas classical bioisosteres commonly conserve much of the same structural properties, nonclassical bioisosteres are much more dependent on the specific binding needs of the ligand in question and may substitute a linear functional group for a cyclic moiety, an alkyl group for a complex heteroatom moiety, or other changes that go far beyond a simple atom-for-atom switch.
