WebBinding affinity for a chiral drug can differ for diastereomers and between enantiomers. For the virtual screening and computational design stage of drug development, this problem can be compounded by incomplete stereochemical information in structure libraries leading to a "coin toss" as to whether or not the "ideal" chiral structure is present. WebJan 8, 2024 · With an idea that homochirality may have originated at monomer level, some researches focused on the formation of pure-chirality crystal from racemic solution of small molecules, via a process named ‘chiral amnesia’ [3,7]. A major problem regarding this thought is: even if pure-chirality monomers can assemble this way, to take part in ...
WebJan 3, 2015 · A molecule is considered chiral if there exists another molecule that is of identical composition but which is arranged in a non-superposable mirror image. Also the presence of an asymmetric carbon atom is often the feature that causes chirality in molecules. Two mirror images of a chiral molecule are called enantiomers or optical …
