Description

Smooth Muscle Inhibitory Factor CAS NO 81605-18-7 is a specialized biochemical agent designed to modulate smooth muscle contractility. This compound is critical for research and development in pharmacology and physiology, where precise control of smooth muscle activity is required. It is primarily utilized by pharmaceutical researchers, contract research organizations (CROs), and academic institutions focused on cardiovascular, respiratory, and gastrointestinal systems.

Application

• Pharmacological Research: Used as a reference standard and active agent in studies investigating smooth muscle relaxation mechanisms and drug discovery for conditions like hypertension, asthma, and irritable bowel syndrome (IBS).
• Biochemical Assay Development: Serves as a key component in in vitro assay systems to screen and validate potential therapeutic compounds targeting smooth muscle receptors and pathways.
• Academic & Institutional Studies: Employed in university and research institute laboratories for fundamental physiological research on vascular tone, bronchial constriction, and peristalsis.
• Contract Manufacturing: Supplied to CROs and CDMOs for preclinical testing and development services for client-sponsored research programs.
• Diagnostic Reagent Formulation: Can be incorporated into specialized diagnostic kits and reagents used for studying smooth muscle function in clinical research settings.
