In an article, published in an article, once mentioned the application of 4175-77-3, Name is 2,4-Dibromothiazole,molecular formula is C3HBr2NS, is a conventional compound. this article was the specific content is as follows.HPLC of Formula: C3HBr2NS
2-Fluoromethyl analogs of (3-[(2-methyl-1,3-thiazol-4yl)ethynyl]pyridine) were synthesized as potential ligands for metabotropic glutamate subtype-5 receptors (mGluR5s). One of these, namely, 3-fluoro-5-(2-(2-(fluoromethyl) thiazol-4-yl)ethynyl)benzonitrile (3), was found to have exceptionally high affinity (IC50 = 36 pM) and potency in a phosphoinositol hydrolysis assay (IC50 = 0.714 pM) for mGluR5. Compound 3 was labeled with fluorine-18 (t1/2 = 109.7 min) in high radiochemical yield (87%) by treatment of its synthesized bromomethyl analog (17) with [18F] fluoride ion and its radioligand behavior was assessed with positron emission tomography (PET). Following intravenous injection of [18F]3 into rhesus monkey, radioactivity was avidly taken up into brain with high uptake in mGluR5 receptor-rich regions such as striata. [18F]3 was stable in monkey plasma and human whole blood in vitro and in monkey and human brain homogenates. In monkey in vivo, a single polar radiometabolite of [ 18F]3 appeared rapidly in plasma. [18F]3 merits further evaluation as a PET radioligand for mGluR5 in human subjects.
