Product Overview:
12-epi LTB3 is an LTB isomer that would not be formed either by known enzymatic or non-enzymatic processes. The conversion of LTA into different isomers of LTB is complex, and has generated confusion in the past. The enzymatic hydrolysis of LTA leads to LTB, which is the corresponding 5(S),12(R)-dihydroxy acid containing a 6(Z),8(E),10(E) conjugated triene. Non-enzymatic hydrolysis of LTA produces none of this material, but instead produces both the 12(S) and the 12(R) isomers of LTB in which the triene component now contains a 6-trans double bond.{2784} 12-epi (or 12(S)) LTB isomers which contain the natural 6-cis olefin are not produced either by enzymatic or by non-enzymatic processes. Further, 3-series LTs (derived from Mead acid) are only seen in essential fatty acid deficiency. Mead acid is a good substrate for 5-lipoxygenase, leading to LTA3. Enzymatic conversion of LTA3 to LTB3 is very low because LTA3 is actually an inhibitor of LTA hydrolase.{4349} Non-enzymatic hydrolysis of LTA3 leads to 6-trans-12-epi LTB3, and to 6-trans LTB3. The biological activity of 12-epi LTB3 has not been explored.

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.
