new chemical entities were screened in vitro for their cytotoxic activity towards various tumor cell lines. Of the compounds screened, 6c and 9d exhibited significant activity and the most active analogue 6c displayed promising cytotoxicity against PC-3 (IC50 of 3.12 ± 0.11 μM), DU-145, NCI-H460 and 4 T1 cell lines. Further, 6c and 9d have 2.1 and 1.4 times more aqueous solubility, respectively, than

kbar or 1 bar pressures. The resultant substitution and elimination reaction product distributions were analyzed. The application of pressure enhanced the progress of the fluoride-ionsubstitutionreactions. The degree of selectivity of the one reaction over the other was found to be a function of tosylate substrate structure and the amount of pressure applied. The exclusive formation of fluoroalkanes

towards the development of potent cytotoxic agents, a series of some new curcumin inspired indole analogues, in which indole and phenyl moieties are linked on either sides of 1,5-diaryl-1,4-pentadien-3-one system have been synthesized and characterized by spectral data. All the newly synthesized analogues were tested for their cytotoxic potential against a panel of eight cancer cell lines namely, lung

develop new curcumin inspired analogues as potent anticancer agents, we synthesized a series of (1E,4E)-1-phenyl-5-(3-phenylimidazo[1,2-a]pyridin-2-yl)penta-1,4-dien-3-ones (12a–t) as tubulin polymerization inhibitors. An initial screening was carried out to evaluate their cytotoxic potential on a panel of six cancer cell lines namely, cervical (HeLa), gastric (HGC-27), lung (NCI-H460), prostate (DU-145
为了开发新的姜黄素激发类似物作为有效的抗癌药,我们合成了一系列(1 E,4 E)-1-苯基-5-(3-苯基咪唑并[1,2- a ]吡啶-2-基) penta-1,4-dien-3-ones(12a–t)作为微管蛋白聚合抑制剂。初步筛选以评估其对六种癌细胞系的细胞毒性潜力,这六种癌细胞系分别是宫颈癌(HeLa),胃癌(HGC-27),肺癌(NCI-H460),前列腺癌(DU-145和PC-3)和乳房(4T1),使用MTT分析。在测试的化合物中,化合物12e,12r和12t显示出有效的生长抑制作用,而12t (1 E,4 E)-1-(3-(3,4-二氟苯基)咪唑并[1,2 - a ]吡啶-2-基)-5-(2,4,6-三甲氧基苯基)penta-1,4-dien-3-一个}是该系列中最活跃的成员,抑制了所有测试细胞系的生长,IC 50值在1.7 – 2.97μM之间变化。此外,12t对PC-3,
