Olanexidine Hydrochloride semihydrate

Olanexidine Hydrochloride semihydrate (CAS No.: 218282-71-4) is a synthetic small molecule monobiguanide and cationic antimicrobial research reagent broadly categorized under antiseptic and preservative chemistry for microbiology and drug discovery support studies, with reported bactericidal activity against diverse Gram positive and Gram negative bacterial species and a functional profile consistent with membrane active biguanide like compounds that primarily interact with negatively charged microbial cell envelope components, disrupt membrane integrity, increase permeability, and induce rapid loss of cellular viability rather than selective modulation of a single canonical host signaling target, and therefore it is generally positioned in anti infective mechanism research focused on bacterial membrane biology, resistance surveillance, biofilm associated phenotypes, and formulation compatibility assessments; based on available class level evidence, in vitro potency is typically discussed in qualitative to semi quantitative terms spanning low micromolar to higher micromolar concentration ranges depending on strain background, inoculum, medium composition, and exposure time, while precise MIC or killing kinetics should be established empirically under laboratory specific protocols, and common research uses include antimicrobial susceptibility testing panels, contamination control and preservative challenge experiments, exploratory combination screening with other anti infective agents, and evaluation in cell based infection or inflammation related experimental systems and nonclinical animal infection models where applicable to study pharmacology or translational biomarkers, with the concentrations or doses used in experiments typically depending on specific experimental designs and research objectives.
