2-(Alkyl(aryl)amino)thiazol-4(5H)-ones can regioselectively be prepared from monoalkyl(aryl)thioureas and maleimides. In solution, the former heterocycles exist in a tautomeric equilibrium with 2-(alkyl(aryl)imino)thiazolidin-4-ones and the substituent on the exocyclic nitrogen atom governs the ratio of these tautomers. Isomers with the alkyl group in the endocyclic position can be obtained fro...
A series of new hexahydroquinoline and 1,4-dihydropyrimidine derivatives were synthesized. Condensation of 2-methyl- thiazole-4-carboxaldehyde (1) with 1,3-cyclohexanedione and alkyl 3- aminocrotonate afforded 4-(2-methyl-thiazol-4-yl)-hexahydroquinoline while condensation of aldehyde (1) with benzoyl acetone and thiourea gave 1,4-dihydropyrimidine derivatives. The stereochemistry of 1,4-dihydr...
Purpose: We previously identified novel thiazole derivatives able to reduce histone acetylation and histone acetyltransferase (HAT) activity in yeast. Among these compounds, 3-methylcyclopentylidene[4-(40-chlorophenyl)thiazol-2-yl]hydrazone (CPTH6) has been selected and used throughout this study. Experimental Design: The effect of CPTH6 on histone acetylation, cell viability and differentiatio...
Correction: Physiological characterization of a novel PPAR pan agonist, 2-(4-(5,6-methylenedioxybenzo[d]thiazol-2-yl)-2methylphenoxy)-2-methylpropanoic acid (MHY2013) Hye Jin An, Bonggi Lee, Dae Hyun Kim, Eun Kyeong Lee, Ki Wung Chung, Min Hi Park, Hyoung Oh Jeong, Sung Min Kim, Kyoung Mi Moon, Ye Ra Kim, Seong Jin Kim, Hwi Young Yun, Pusoon Chun, Byung Pal Yu, Hyung Ryong Moon and Hae Young Chung
New N,N-disubstituted β-amino acids and their derivatives with thiazole, aromatic, and heterocyclic substituents were synthesized from N-phenyl-N-thiocarbamoyl-β-alanine by the Hantzsch method; derivatives with hydrazone fragments were also obtained. Some of the synthesized compounds exhibited discrete antimicrobial activity, and 3-[(4-oxo-4,5-dihydro-1,3-thiazol-2-yl)(phenyl)amino]propanoic ac...
Symmetric and non-symmetric 2-(N-H, N-methyl, N-ethylenyl and N-aryl)guanidinebenzothiazoles were synthesized from the reaction of ammonia, methylamine, pyrrolidine and aniline with dimethyl benzo[d]thiazol-2-yl-carbonodithioimidate as intermediate. The products were characterized by ¹H-, ¹³C-NMR spectroscopy and three of them by X-ray diffraction analysis. HN-phenyl protons formed intramolecul...
Versatile synthetic strategies that access diverse chemical substrates in a highly chemoand stereoselective manner are crucial but demanding. Construction of chiral molecules with multiple (hetero)quaternary carbon stereocenters in a single fashion is a particularly significant challenge, with important applications in the synthesis of a range of bioactive compounds containing the 1,4-sulfur br...
