WebFeb 21, 2024 · A Chiral Center is an atom that has 4 different group bonds. These group bonds are in such a way that it has a non superimposable mirror image. It is also called a chiral atom, chiral center, or chirality. It is a stereocenter that has a set of atoms in such a way that the structure cannot be superimposed on its mirror image. WebDrugs that exhibit handedness are referred to as chiral drugs. Chiral drugs that are equimolar (1:1) mixture of enantiomers are called racemic drugs and these are obviously devoid of optical rotation. The most commonly encountered stereogenic unit, [2] that confers chirality to drug molecules are stereogenic center.

WebDiastereomeric drugs (multiple chiral centers) A large number of drugs have multiple chiral centers. The total number of isomers possible is 2(n) where n is the number of chiral centers present in the molecule. In the example below (Figure 8), each isomer has one enantiomer where the stereochemistry at both chiral centers are inverted.
