Coproporphyrin III dihydrochloride

Coproporphyrin III dihydrochloride 是鼻孔和皮肤相关的丙酸杆菌属排出的生物活性分子，可诱导金黄色葡萄球菌聚集（条件：早期静止期生长期间，低 pH 值：4-6）。Coproporphyrin III dihydrochloride 还会诱导金黄色葡萄球菌的非生物表面上形成不依赖血浆的生物膜。Coproporphyrin III dihydrochloride 可能是金黄色葡萄球菌在鼻孔或丙酸杆菌和金黄色葡萄球菌栖息的其他部位聚集和/或生物膜形成的重要介质。 Coproporphyrin III (Zincphyrin) is a naturally occurring porphyrin derivative that is mainly found in urine. IC50和靶点：Human Endogenous Metabolite In Vitro：Coproporphyrin III methyl ester is repeatedly isolated in considerable amount from both feces and urine. A great increase of coproporphyrin III excretion is unaccompanied by symptoms or signs of porphyria, metal or chemical poisoning or liver disease. Primary cultures of chick embryo hepatocytes have been used to study the mechanism by which chemicals cause accumulation of intermediates of the heme synthetic pathway. In the presence of the porphyrin precursor, 5-aminolevulinate (ALA), addition of insulin causes a striking increase in accumulation of uroporphyrin I and coproporphyrin III. Antioxidants abolishes the uroporphyrin I accumulation and increases coproporphyrin III. In Vivo：Urinary porphyrin and DMA profile can be used as an early warning biomarker for chronic MMA exposure before the onset of cancer. After 4 weeks the level of coproporphyrin III concentration significantly increases in all the treatment groups compared to the control.
