Apexbio Technology LLC Indapamide 26807-65-8 5g
Indapamide (CAS 26807-65-8) is a sulphonamide-derived diuretic structurally distinct from thiazides It functions by inhibiting sodium reabsorption primarily at the distal convoluted tubules of the nephron resulting in increased excretion of sodium and water This action reduces plasma volume and peripheral vascular resistance contributing to its antihypertensive effects Indapamide is also studied for its utility in models of decompensated cardiac failure due to its natriuretic and vasodilatory properties making it relevant for research into cardiovascular disease and fluid balance regulation
Apexbio Technology LLC Cephalexin 15686-71-2 10mM (in 1mL H2O)
Cephalexin (15686-71-2) is a small-molecule inhibitor targeting penicillin-binding proteins (PBPs) It is designed to disrupt the bacterial cell wall synthesis thereby compromising bacterial cell wall integrity Cephalexin exerts its biological activity primarily through inhibition of peptidoglycan layer assembly by binding to PBPs In in vitro studies Cephalexin demonstrates broad-spectrum antibacterial inhibition with IC50 values typically observed in the low-micromolar concentration range depending on bacterial species and experimental conditions Based on these pharmacological properties Cephalexin holds research potential in studying bacterial infections such as pneumonia streptococcal pharyngitis and bacterial endocarditis as well as in antimicrobial susceptibility assays resistance mechanism analysis and antibiotic interaction studies
