  The condensation of N‐aryl thioureas with 3‐bromo‐acetylacetone in neutral solvent acetone not only led to 5‐acetyl‐4‐methyl‐2‐(substituted anilino) thiazoles 3 but also 2‐imino‐3‐(substituted phenyl)‐4‐methyl‐5‐acetyl‐2,3‐dihydrothiazoles 4. Further study found that different reaction solvents displayed an important role toward the ratio of aminothiazoles 3 and iminodihydrothiazoles 4, and the reaction

  Thirty-seven (E)-1-(4-methyl-2-arylaminothiazol-5-yl)-3-arylprop-2-en-1-ones were synthesized via Claisen-Schmidt condensation of 1-(4-methyl-2-(arylamino)thiazol-5-yl) ethanone with the corresponding arylaldehydes. All these thiazolyl-chalcones were characterized and evaluated by MTT assay on human cancer cell lines BGC-823, PC-3, NCI-H460, BEL-7402 in vitro. Compounds 5, 8, 26, 37 and 41 are effective against cancer cell lines with IC(50)s below 10 mu M. The antitumor activity in ICR mice bearing sarcoma 180 tumors indicates compounds 10 and 41 have moderate in vivo activity with 22-25% tumor-weight inhibition. (C) 2010 Elsevier Ltd.

  In the present study, series of novel compounds (E)-2-(1-(4-methyl-2-(substituted-phenylamino)thiazol-5-yl)ethylidene)hydrazinecarbothio-amide (5a-j) and (E)-N-cyclohexyl-2-(1-(4-methyl-2-(substituted-phenylamino)thiazol-5-yl)ethylidene)hydrazinecarbothioamide (6a-j) have been synthesized using microwave irradiation method in high yields and characterized by IR, H-1 NMR, C-13 NMR and mass spectral analysis. Synthesized compounds were evaluated for their in-vitro antimicrobial, antimalarial and anti-tuberculosis activity as well as in-silico study. The obtained results indicate that compound 6b and 6g were found to be the most potent against S. aureus bacterial strain. Further, the molecular docking study has been performed for all the new compounds with the immune system of S. aureus (PDB ID: 5D1Q) as a target enzyme, and this study validated the experimental results.

  A synthesis of aminothiazoles from various 1,3‐dicarbonyls and thioureas without a leaving group has been developed. The reaction is photocatalyzed by tetraiodofluorescein, an organic dye. Under irradiation with green LEDs, a sulfur radical is generated in situ from thiourea, followed by addition to the enol tautomer, forming the aminothiazole backbone. This novel strategy provides a greener alternative
