WebBiotransformation reactions can be classified into: a) Nonsynthetic/Phase I/Functionalization reactions: a functional group is generated or exposed—metabolite may be active or inactive. b) Synthetic/Conjugation/ Phase II reactions: metabolite is mostly inactive; except few drugs, e.g. glucuronide conjugate of morphine and sulfate conjugate … WebHere we describe the use of microbial biotransformation as a tool to produce drug metabolites, complementing traditional chemical synthesis and other biosynthetic …

WebDrug metabolism is often considered during drug design. For instance, a drug containing a benzene group may undergo Phase I reactions (e.g.hydroxylation of the ring, favouring the para position). This … WebDrug biotransformation or metabolism principally occurs in the liver, kidney, skin, and GI tract. In the liver, biotransformation involves hydrolysis, oxidation, reduction, or demethylation and conjugation of the metabolite with glycine, glucuronide, sulfate, or hippurate with subsequent secretion into the bile.
