Examples of optical isomers in drugs
http://webhome.auburn.edu/~deruija/pdastch2.pdf WebAn enantiopure drug is a pharmaceutical that is available in one specific enantiomeric form. Most biological molecules (proteins, sugars, etc.) are present in only one of many chiral forms, so different enantiomers of a chiral drug molecule bind differently (or not at all) to target receptors. Chirality can be observed when the geometric ...

Webto geometric isomerism, optical isomerism is also possible. For example, 1,2-dimethylcyclohexane has two geometric isomers, cis and trans, and enantiomers of the trans form; the cis form is a meso compound (Fig. 29). Hence, three stereoisomers are possible. N S O COOH O O NH2 NH O N OCH3 O N S O COOH O O NH2 NH O N O … Webarrangement. Although configurational isomers can be difficult to visualize and understand, they are extremely important especially in biological chemistry. For example, the pain reliever Ibuprofen exists as configurational isomers but only one isomer is effective (the S isomer) in treating pain. Also, the drug L-DOPA (L-
WebOptical isomerism. Optical isomers are the stereoisomers that are nonsuperimposable mirror images of each other. and they differ in the direction in which they rotate plane-polarised light.They do not possess the plane of symmetry. The molecules which are non super-imposable mirror image of each other are called chiral and this property is ... WebOptical isomers of isoflurane exhibited stereoselectivity in their effects, (+)isoflurane being about twofold more effective than the (-)isomer,[25–29] though other studies failed to confirm this.[30–32] Since the safety factor for inhalational anaesthetics is very low, even relatively small degree of stereoselectivity can result in one of ...
