Demeclocyclin hydrochloride hemihydrate (CAS 64-73-3 (anhydrous))

Demeclocycline hydrochloride hemihydrate, assigned the CAS number 64-73-3, is a hemihydrate form of demeclocycline hydrochloride, a tetracycline antibiotic derivative. This compound, similar to other tetracyclines, operates primarily by inhibiting protein synthesis in bacteria. It achieves this through binding to the 30S ribosomal subunit, thereby blocking the attachment of aminoacyl-tRNA to the mRNA-ribosome complex at the acceptor site. This action prevents the addition of new amino acids to the nascent peptide chain, effectively stopping bacterial protein synthesis and halting cell growth. In research environments, demeclocycline hydrochloride hemihydrate is frequently utilized to study the molecular mechanisms of antibiotic action and resistance. It serves as a critical tool for dissecting the interactions between antibiotics and bacterial ribosomes, providing insights into the nuances of ribosomal binding and inhibition by tetracycline-class molecules. Furthermore, this chemical is used in microbiological studies to explore the environmental dynamics of antibiotic resistance, particularly how bacterial populations evolve and adapt in response to the presence of antibiotics. Research involving demeclocycline hydrochloride hemihydrate is crucial for advancing our understanding of microbial ecology and genetics, contributing to the development of more effective strategies for managing and controlling bacterial resistance in various ecosystems.
