Drimentine B (CAS 204398-91-4)

Drimentine B, with the CAS number 204398-91-4, is a compound closely related to Drimentine A and part of the drimentines group, noted for their unique chemical structure that includes a bicyclic system combining pyrrolidine and oxazoline rings. This molecular arrangement is essential for its biological activity, which centers around the inhibition of bacterial type II topoisomerases, such as DNA gyrase and topoisomerase IV. These enzymes play a critical role in DNA replication, transcription, and cell division within bacterial cells by altering the degree of supercoiling of DNA, which is necessary for various cellular processes. Drimentine B′s interaction with these enzymes interferes with their ability to introduce negative supercoils into DNA, effectively halting the bacterial cell processes that depend on proper DNA topology. This specific action makes Drimentine B a valuable tool in microbiological research, particularly in the study of bacterial genetics and enzyme mechanics. Researchers utilize this compound to probe the mechanisms by which bacteria manage DNA supercoiling, cope with topological stress, and develop resistance to agents that target DNA topology. These investigations not only enhance our understanding of bacterial physiology but also contribute to broader discussions on targeting bacterial replication mechanisms in the development of new antibacterial strategies.
