Benzathine penicilline

Benzathine penicilline (CAS No.: 1538-09-6) is a long acting penicillin class antibacterial research compound composed of the benzathine salt form of penicillin G, generally categorized in anti infective pharmacology as a beta lactam antibiotic scaffold used for microbiology, infectious disease mechanism studies, and antimicrobial susceptibility benchmarking in drug discovery workflows; its biological activity is primarily attributed to the penicillin G moiety, which binds penicillin binding proteins involved in bacterial cell wall peptidoglycan cross linking, thereby disrupting cell wall biosynthesis and promoting bacterial lysis in susceptible organisms, with mechanistic relevance to pathways governing peptidoglycan assembly, cell envelope integrity, and downstream bacterial stress responses, while resistance related contexts commonly examined in research include beta lactamase mediated hydrolysis, altered penicillin binding protein profiles, and permeability or efflux associated effects; consistent with its class, in vitro potency is typically evaluated by minimum inhibitory concentration testing and is generally discussed across susceptible strains in low microgram per milliliter to higher concentration ranges depending on species, inoculum, and assay conditions rather than a single fixed value, and cell based or organism level studies usually apply concentration windows selected through standardized susceptibility protocols; in biomedical research settings, this compound is commonly used as a reference antibacterial agent in culture based infection models, comparative screening panels for novel anti infective candidates, and translational preclinical paradigms of bacterial burden control, including investigations of early syphilis relevant pathogen susceptibility at the experimental level, with the concentrations or doses used in experiments typically depending on specific experimental designs and research objectives.
