Roles of the carbamate moiety in drugs and prodrugs

DrugThe role of the carbamate moiety in the drugReference
Docetaxelprolongs drug action, increases drug potency, improves water solubility39
Mytomicin Cparticipates in the formation of an alkylating compound during reaction with target40
Rivastigmine, neostigmine, physostigmine, pyridostigminekey element for interaction with the target38
Ritonavir, amprenavir, atazanavir, darunavirimproves drug bioavailability and potency, engaged in a backbone interaction with protease8
Ombitasvir, elbasvir, daclatasavirimproves drug stability and lipophilicity41
Febendazole, mebendazole, febantel, albendazoleimproves aqueous solubility and bioavailability, increases cytotoxicity42
Mehocarabamol, metaxaloneinhibits acetylcholinesterase at synapses in the autonomic nervous system, neuromuscular junction, and central nervous system43
