- Product Overview:
TRAM-34 is a membrane-permeable inhibitor of the intermediate-conductance calcium-activated potassium channel (IKCa1/KCa3.1).{41340} It blocks IKCa1 (Kds = 20 and 25 nM for the cloned and native channel in COS-7 cells and human T lymphocytes, respectively) with 200- to 1,500-fold selectivity for IKCa1 over Kv (Kv1.1-Kv1.5, Kv3.1, Kv4.2), Kir2.1, BK/KCa1.1, SKCa (rSKCa2, hSKCa2, hSKCa3), native SKCa/KCa2, and CRAC in Jurkat T cells, as well as sodium and chloride channels. It also inhibits nonselective lysophosphatidylcholine-induced cation currents (IC50 = 38 nM).{41342} TRAM-34 suppresses reactivation of human-derived T lymphocytes stimulated with anti-CD3 antibody after an initial pretreatment to upregulate IKCa1 channels (mean EC50s = 295 and 910 nM from sensitive and less sensitive human donors, respectively).{41340} It does not reduce viability of human T lymphocytes at a concentration of 5 ?M over 48 hours incubation. In vitro, TRAM-34 (10-40 ?M) inhibits proliferation of human endometrial cancer cells and induces cell cycle arrest at the G0/G1 phase.{41343} It also inhibits proliferation of LNCaP and PC3 prostate cancer cells and proliferation induced by epidermal growth factor (EGF) in smooth muscle A7r5 cells (IC50 = 8 nM).{41344,41341} In vivo, TRAM-34 (120 mg/kg per day) reduces intimal hyperplasia by approximately 40% after 1, 2, and 6 weeks in a rat model of balloon catheter injury. TRAM-34 (30 ?M) treatment of HEC-1-A cells prior to flank implantation into nude mice slows tumor growth in vivo.
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.
