Product Overview:
Trequinsin is a phosphodiesterase (PDE) 3 inhibitor that is dependent on cyclic AMP (cAMP), with IC50 values of 0.04 and 0.03 nM for PDE3A and PDE3B, respectively, in T84 human colonic adenocarcinoma cell lysates.{39526} In cultured primary rat juxtaglomerular cells, trequinsin stimulates cAMP accumulation when used at a concentration of 10 µM and increases cell membrane capacitance in a patch clamp assay.{39523} Trequinsin also competitively inhibits the multidrug resistant protein 5-mediated export of cGMP from Chinese hamster lung fibroblasts with a Ki value of 240 nM.{39524} In vivo, trequinsin reduces collagen-induced platelet aggregation in rabbits when administered intravenously at a rate of 3 µg/kg per minute, as well as the collagen-induced decrease in mean arterial blood pressure when administered alone or in combination with prostacyclin.{39522}

Cayman Chemical's mission is to help make research possible by supplying scientists worldwide with the basic research tools necessary for advancing human and animal health. Our utmost commitment to healthcare researchers is to offer the highest quality products with an affordable pricing policy.

Our scientists are experts in the synthesis, purification, and characterization of biochemicals ranging from small drug-like heterocycles to complex biolipids, fatty acids, and many others. We are also highly skilled in all aspects of assay and antibody development, protein expression, crystallization, and structure determination.

Over the past thirty years, Cayman developed a deep knowledge base in lipid biochemistry, including research involving the arachidonic acid cascade, inositol phosphates, and cannabinoids. This knowledge enabled the production of reagents of exceptional quality for cancer, oxidative injury, epigenetics, neuroscience, inflammation, metabolism, and many additional lines of research.

Our organic and analytical chemists specialize in the rapid development of manufacturing processes and analytical methods to carry out clinical and commercial GMP-API production. Pre-clinical drug discovery efforts are currently underway in the areas of bone restoration and repair, muscular dystrophy, oncology, and inflammation. A separate group of Ph.D.-level scientists are dedicated to offering Hit-to-Lead Discovery and Profiling Services for epigenetic targets. Our knowledgeable chemists can be contracted to perform complete sample analysis for analytes measured by the majority of our assays. We also offer a wide range of analytical services using LC-MS/MS, HPLC, GC, and many other techniques.
