Posted on March 21, by mcb An excellent J. The author gives a brief introduction to the concept of biosisosterism classical and non-classical but concentrates on pulling together numerous recent examples which together illustrate the use of bioisosteres to address a diverse range of issues that are commonly encountered in the process of drug discovery.

A really nice paper and highly recommended reading material. Isosteres of Hydrogen: Deuterium as an isostere of hydrogen. Deuterium substitution to modulate metabolism. Deuterium substitution to modulate metabolism and toxicity. Deuterium to slow epimerization.

Fluorine as an isostere of hydrogen. Fluorine for hydrogen exchange to modulate metabolism. Deploying fluorine to modulate basicity in KSP inhibitors. Substitution of hydrogen by fluorine as a strategy for influencing conformation. Silicon as an isostere of carbon. Silicon as a carbon isostere in biogenic amine reuptake inhibitors.

Dut All lily of the valley flower Bioisostere increase target interaction and selectivity: Drug Discovery, Design and Development: Bioisosterism is used to reduce toxicity, change bioavailabilityor modify the activity of the lead compound, and may alter the metabolism of the lead. The main use of this term and its techniques are related to pharmaceutical sciences. Because the fluorine atom is similar in size to the hydrogen atom the overall topology of the molecule is not significantly affected, leaving the desired biological activity unaffected. Bivalent atom or groups. Structural size, shape, H-bonding are important 2.
