3-Amino-4-deoxy-4-imino Rifamycin S (CAS 62041-01-4)

3-Amino-4-deoxy-4-imino Rifamycin S is an analog of rifamycin, distinguished by its structural modification which significantly influences its role in research, particularly in the study of bacterial RNA synthesis inhibition. This chemical specifically targets bacterial DNA-dependent RNA polymerase, thereby obstructing the transcription process, which is a vital step in bacterial gene expression and replication. The mechanism of action of 3-Amino-4-deoxy-4-imino Rifamycin S involves binding to the beta subunit of RNA polymerase, leading to a blockade of the RNA synthesis pathway. This unique interaction is crucial for studies focused on the transcriptional machinery of bacteria, especially in understanding how modifications in antibiotic structure can impact their efficacy and specificity. In research, this compound is used to investigate the dynamics of transcription inhibition and to explore potential strategies for overcoming antibiotic resistance. It provides a valuable tool for dissecting the mechanisms by which bacteria develop resistance to rifamycin drugs and for designing inhibitors that are less susceptible to resistance mechanisms. Studies involving 3-Amino-4-deoxy-4-imino Rifamycin S contribute to a deeper understanding of microbial physiology and the development of novel antibacterial agents.
