Chiral Inversion of Drugs: Coincidence or Principle?
WebFor chiral hydroxyl group drugs, the redox enzyme system may be one of the key factors for chiral inversion in vivo. Conclusion: In vitro and in vivo chiral inversion is a very complex problem and may occur during every process of ADME. Nowadays, research on chiral metabolism in the liver has the most attention, while neglecting the chiral ... Chiral inversion is the process of conversion of one enantiomer of a chiral molecule to its mirror-image version with no other change in the molecule. Chiral inversion happens depending on various factors (viz. biological-, solvent-, light-, temperature- induced, etc.) and the energy barrier associated … See more Essentially there are two types of chiral inversion, unidirectional and bidirectional. Inversion process is dependent on species and substrate. Unidirectional chiral inversion (enzyme mediated) was … See more It is well documented that (R)-enantiomers of profens in the presence of coenzyme A (CoA), adenosine triphosphate (ATP) and Mg are converted to active (S)-forms. The pathways of chiral … See more Chiral inversion is a very important part of designing and making drugs. Because this process can change how chiral drugs work in the body and can cause side effects that can be serious or … See more • Ibuprofen • Dexibuprofen • Ketoprofen • Thalidomide • Fenoprofen • Chiral drugs See more Chiral drugs with stereo-labile configuration are likely to undergo interconversion of the enantiomers that may be enzymatic … See more Enantiomers of a chiral drug often interact in an enantioselective way in a chiral environment.
