The synthesis of new thiazol-2-(3H)-ones as an elaboration of potent HNE inhibitors with an isoxazol-5-(2H)-one scaffold that recently identified was described. Two-dimensional NMR spectroscopic techniques and tandem mass spectrometry allowed correct assignment of the structure for final compounds arising from both tautomers of the thiazol-2-(3H)-one nucleus (N-3 of the thiazol-2-(3H)-one and 3-OH of the thiazole). All new compounds were tested as HNE inhibitors and no activity was found at the highest concentration used (40 渭M), demonstrating that the thiazol-2-(3H)-one was not a good scaffold for HNE inhibitors. Mol. modeling experiments indicated that the low-energy pose might limit the nucleophilic attack on the endocyclic carbonyl group of the thiazolone-based compounds by HNE catalytic Ser195, in contrast to isoxazol-5-(2H)-one analogs. In the experiment, the researchers used many compounds, for example, Chloromethyl benzoate (cas: 5335-05-7Recommanded Product: 5335-05-7).
Chloromethyl benzoate (cas: 5335-05-7) belongs to organic chlorides. Organic chlorides can be used in production of: PVC, pesticides, chloromethane, teflon, insulators. Alkyl chlorides readily react with amines to give substituted amines. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.Recommanded Product: 5335-05-7
