Drug Isomer

Drug Isomer

Drug isomers are compounds with the same molecular formula but different atomic arrangements or spatial configurations. They are divided into structural isomers and stereoisomers, and have different biological activities, safety and metabolic characteristics. Drug isomers can be used as drug improvement groups or drug efficacy control groups. For example, Carvedilol has higher bioavailability and better safety than (R)-Carvedilol.

    Enitociclib ((+)-BAY-1251152; (+)-VIP152) is a selective CDK9 inhibitor (IC50=3 nM) that inhibits transcriptional elongation by blocking Ser2/Ser5 phosphorylation of RNA polymerase II. Enitociclib specifically depletes key short-lived proteins such as c-MYC, MCL-1 and induces tumor cell apoptosis. Enitociclib also interferes with the production of enhancer RNAs (eRNA) and enhancer-promoter interactions, and downregulates oncogene expression at the epigenetic level. Enitociclib exerts synergistic effects with agents including Bortezomib (HY-10227), Lenalidomide (HY-A0003), Pomalidomide (HY-10984), Venetoclax (HY-15531) and Paclitaxel (HY-B0015), and even reverses paclitaxel resistance.
