53266-94-7, An article , which mentions 53266-94-7, molecular formula is C7H10N2O2S. The compound – Ethyl 2-(2-aminothiazol-4-yl)acetate played an important role in people’s production and life.

The synthesis of different diazonium salts derived from homo- and heterocyclic aromatic amines bearing anionic residues is described.The chemical stabilities of these compounds were established at different pH’s, and the compounds were tested accordingly in binding experiments for the rat brain gamma-aminobutyric acid (GABA) receptor, for which they could ultimately be used as irreversible affinity or photoaffinity probes.The aromatic heterocyclic series studied were 2-aminoimidazole, 2-aminothiazole, and 4-aminopyridine N-oxide.The derived diazonium salts are unstable compounds at neutral pH unless they are able to be deprotonated to the corresponding diazo form.As such, the 2-diazoimidazole-4(5)-acetic acid (3b) is stable in neutral medium and recognizes the GABA receptor (IC50 = 70 muM).The homocyclic aromatic diazonium salt showed sufficient stability to be tested in binding experiments.The diazonium salts derived from m-sulfanic acid and 8-sulfonaphthylamine were the most interesting (10b, IC50 = 10 muM; 15b, IC50 < 100 muM).In this series, the compounds that deprotonate at neutral pH (hydroxybenzenediazonium derivatives 12b-14b) showed increased chemical stability but decreased affinity for the GABA receptor.This difference between the diazoimidazole and the diazohydroxybenzene series is attributed to a different charge distribution between the two series.The ligands 3b,10b, and 15b can be used as potential irreversible probes for the GABA receptor.

Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 121-66-4, Name is 5-Nitrothiazol-2-amine121-66-4, introducing its new discovery.

Various hetarylazo dyes have been synthesized by coupling reactions between diazotised 2-amino-5-nitrothiazole and 2-chloroaniline, 1,3-dihydroxybenzene and N-phenyl naphthylamine. Spectral measurements were carried out in different solvents. The solvatochromic behaviour of the dyes in various solvents were evaluated. The 2-amino-5-nitrothiazole dye derivatives absorb maximally at longer wavelengths and are tinctorially stronger than the 1-naphthylamine dyes, although the former dyes have higher extinction coefficients. Also, the synthesized dyes exhibit positive solvatochromism so that the absorption bands of the dye, move towards longer wavelengths as the polarity of the solvent increases.

Sphingosine 1-phosphate (S1P) is a pleiotropic signaling molecule that interacts with its five G-protein coupled receptors (S1P1-5) to regulate cell growth and survival and has been implicated in a variety of diseases including cancer and sickle cell disease. As the key mediators in the synthesis of S1P, sphingosine kinase (SphK) isoforms 1 and 2 have attracted attention as viable targets for pharmaceutical inhibition. In this article, we describe the design, synthesis, and biological evaluation of aminothiazole-based guanidine inhibitors of SphK. Surprisingly, combining features of reported SphK1 inhibitors generated SphK1/2 dual inhibitor 20l (SLC4011540) (hSphK1 Ki = 120 nM, hSphK2 Ki = 90 nM) and SphK2 inhibitor 20dd (SLC4101431) (Ki = 90 nM, 100-fold SphK2 selectivity). These compounds effectively decrease S1P levels in vitro. In vivo administration of 20dd validated that inhibition of SphK2 increases blood S1P levels.

An efficient and practical C?N bond formation methodology for the synthesis of N-alkylated (benzo)thiazoles was developed, via the copper-catalyzed one-pot two-step reactions of 2-amino(benzo)thiazoles and aldehydes (ketones) with tosylhydrazide. This cross-coupling reaction proceeded smoothly and tolerated a broad range of functional groups (46 examples). A variety of functionalized N-alkylated (benzo)thiazoles were obtained in moderate to high yields. Notably, gram-scale synthesis of fanetizole (anti-inflammatory drug) was also realized through this protocol.
