A new class of imidazo[2,1-b]thiazole chalcone derivatives were synthesized and evaluated for their anticancer activity. These chalcone derivatives show promising activity, with logGI50 values ranging from -7.51 to -4.00. The detailed biological aspects of these derivatives toward the MCF-7 cell line were studied. Interestingly, these chalcone derivatives induced G 0/G1-phase cell-cycle arrest, down-regulation of G 1-phase cell-cycle regulatory proteins such as cyclin D1 and cyclin E1, and up-regulation of CDK4. Moreover, these compounds elicit the characteristic features of apoptosis such as enhancement in the levels of p53, p21, and p27, suppression of NF-κB, and up-regulation of caspase-9. One of these chalcone derivatives, 3d, is potentially well suited for detailed biological studies, either alone or in combination with existing therapies. Breaking the cycle: We undertook an extensive examination of the ability of a series of new chalcone derivatives to regulate the cell cycle and to induce apoptosis in various cancer cell lines. Compound 3d is a particularly suitable candidate for further detailed biological investigations, especially in the treatment of breast cancer.

α- or β-Trifluoromethyl epoxysulfones: new C3 reagents for heterocyclisation
Laduron, Frederic,Janousek, Zdenek,Viehe, Heinz, G.
, p. 83 - 86 (2007/10/02)
The syntheses of α- and β-trifluoromethyl epoxysulfones 1 and 2 are described.Compound 1 reacts with nucleophiles and bis-nucleophiles to furnish trifluoromethyl ketones and trifluoromethyl heterocycles in good yield, while its isomer 2 leads to the opposite thiazole regioisomers with thioamides. - Keywords: Trifluoromethyl epoxysulfones; Heterocyclisation; Regioisomers; NMR spectroscopy; IR spectroscopy
Syntheses of Trifluoromethyl Heterocycles
Moazzam, Muhammad,Parrick, J.
, p. 1051 - 1053 (2007/10/02)
Mono and bicyclic heterocycles bearing trifluoromethyl substituent have been synthesized and characterized by spectral studies. 4(5)-Trifluoromethylimidazole (3) is prepared from the reaction of 3,3-dibromo-1,1,1-trifluoroacetone (2) with formaldehyde and ammonia.N-Methylation of 3 by phase transfer reaction gives 1-methyl-4-trifluoromethylimidazole (4). 2-Amino-4-trifluoromethylimidazole (5) is similarly obtained from 3-bromo-1,1,1-trifluoroacetone (1) and thiourea.The reaction of 1 with 2-aminopyridine and 2-aminothiazole gives 2-trifluoromethylimidazopyridine (7) and 6-trifluoromethylimidazothiazole (9) respectively.
