A structure based medium throughput virtual screening campaign of BITS-Pilani in house chemical library to identify novel binders of Mycobacterium tuberculosis gyrase ATPase domain led to the discovery of a quinoline scaffold. Further medicinal chemistry explorations on the right hand core of the early hit, engendered a potent lead demonstrating superior efficacy both in the enzyme and whole cell screening assay. The binding affinity shown at the enzyme level was further corroborated by biophysical characterization techniques. Early pharmacokinetic evaluation of the optimized analogue was encouraging and provides interesting potential for further optimization.

Electric Literature of 121-66-4, An article , which mentions 121-66-4, molecular formula is C3H3N3O2S. The compound – 5-Nitrothiazol-2-amine played an important role in people’s production and life.

The highly selective glycogen synthase kinase-3 (GSK-3) inhibitor N-(4-methoxybenzyl)-N?-(5-nitro-1,3-thiazol-2-yl)urea (AR-A014418) was radiolabeled with carbon-11 (11C; half-life = 20.4 min) at the urea moiety via [11C]CO2 fixation. Reaction of [ 11C]CO2 with 4-methoxybenzylamine in the presence of a CO2 fixating base was followed by dehydration with POCl3 and addition of 2-amino-5-nitrothiazole to prepare [11C-carbonyl] AR-A014418. This reaction resulted in an 8% uncorrected radiochemical yield, based on [11C]CO2, with high specific activity (4 Ci/mumol) within 30 min. An in vitro GSK-3beta enzyme activity assay revealed that AR-A014418 (Ki = 770 nM) is not as potent as previously claimed. The [11C]CO2 fixation methodology described herein should prove generally applicable to preparing 1-aryl-3-benzyl-[ 11C-carbonyl] ureas as radiotracers for positron emission tomography.

A novel hetrocyclic mono azo dye ligand 5-[2-(5-nitro thiazolyl)azo]-2-amino-4-methyl pyridine (NTAPy) was prepared by coupling reaction between 5-nitro thiazole diazonium chloride with 2-amino-4-methyl pyridine in alkaline alcoholic solution . Anew series of some transition metal complexes of Cr(III), Mn(II), Fe(III), Co(II), Ni(II), Cu(II) and Zn(II) ions were prepared forming seven chelate complexes . The prepared hetrocyclic mono azo dye ligand and its metal complexes were checked by different spectral technique such as 1H-NMR, 13C-NMR,FT-IR, electronic spectra, mass spectrum, C.H.N analysis, magnetic susceptibility, atomic absorption and molar conductivity. The analytical data show that the metal to ligand ratio [M:L] in all complexes are[1:2] and the mono azo ligand behavior as a bidentate chelating agent. The coordination number of all metal ions is found to be six in coordination through the nitrogen atom of azo group (N3) farthest of thiazole ring and nitrogen atom (N3) of thiazole molecule forming five member metlo ?ring. All metal complexes of non- electrolytic and no conductive species exist excepted the Cr(III)and Fe(III)complexes are 1:1 electrolyte.

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.

Example 1 Preparation of N-(5-Nitro-thiazol-2-yl)-2-pyridin-3-yl-acetamide (compound 13) To a solution of 3-Pyridylacetic acid hydrochloride (2.076 g, 12 mmol) in anhydrous THF, 1.5 equivalents of CDI (18 mmol, 2.916 g) in anhydrous THF and 1 equivalent of NEt3 (1.66 mL) are added. The resulting mixture is allowed to stir at room temperature for 4 hours. Then, 2-amino-5-nitro-thiazol (12 mmol, 1.740 g) in THF is added to the reaction mixture and this is stirred at room temperature for 10 h. When the reaction is completed, the solvent is evaporated and the resulting brown crude is dissolved in CH2Cl2 and water. This mixture produces a yellow precipitate, which is filtered and washed with water to obtain the desired compound as a yellow solid (2.300 g, yield: 73 %, 265 M+). 1H-NMR (DMSO): 3.95 (s, 2H); 7.38 (dd, 1H); 7.74 (d, 1H); 8.50 (d, 1H); 8.52 (s, 1H); 8.63 (s, 1H) 13C-NMR (DMSO): 38.52; 123.4; 129.7; 137.1; 141.7; 142.6; 148.1; 150.3; 161.8; 170.7
