Spectral studies of 2-pyrazoline derivatives: Structural elucidation through single crystal XRD and DFT calculations
摘要:
A series of biologically active N-thiocarbamoyl pyrazoline derivatives have been synthesized using anhydrous potassium carbonate as the catalyst. All the synthesized compounds were characterized by FT-IR, H-1 NMR, C-13 NMR spectral studies, LCMS, CHN Analysis and X-ray diffraction analysis (compound 7). In order to supplement the XRD parameters, molecular modelling was carried out by Gaussian 03W. From the optimized structure, the energy, dipolemoment and HOMO-LUMO energies of all the systems were calculated. (C) 2013 Elsevier B.V. All rights reserved.

A series of 3-(substituted aroyl)-4-(3,4,5-trimethoxyphenyl)-1H-pyrrole derivatives were synthesized and determined for their anticancer activity against eleven cancer cell lines and two normal tissue cell lines using MTT assay. Among the synthesized compounds, compound 3f was the most potent compound against A375, CT-26, HeLa, MGC80-3, NCI-H460 and SGC-7901 cells (IC50 = 8.2 - 31.7 μm); 3g, 3n and

A series of 1,2,4-triazolo[1,5-a]pyrimidine derivatives have been designed and synthesized as combretastatin CA-4 analogs. They were screened for anticancer and tubulin polymerization inhibition activities. The trimethoxyphenyl 1,2,4-triazolo[1,5-a]pyrimidine derivative 4c showed significant antiproliferative activity in which it exhibited IC50 = 0.53 μM against HCT-116 cancer cell line. It was further
一系列 1,2,4-三唑并[1,5- a ]嘧啶衍生物已被设计并合成为康布他汀 CA-4 类似物。筛选它们的抗癌和微管蛋白聚合抑制活性。三甲氧基苯基 1,2,4-三唑并[1,5- a ]嘧啶衍生物4c显示出显着的抗增殖活性,其中它对 HCT-116 癌细胞系的IC 50 = 0.53 μM。 如果与康布他汀 IC 50 = 1.10 μM相比,它作为微管蛋白聚合抑制剂进一步测试显示 IC 50 = 3.84 μM。进一步的机制研究表明,化合物4c能通过诱导细胞凋亡和将细胞周期阻滞在G 2 /M期而明显抑制HCT-116癌细胞的增殖。此外,对接研究表明,化合物4c与微管蛋白的秋水仙碱结合位点具有良好的拟合度。因此,它被认为是一种值得进一步开发作为微管蛋白聚合抑制剂的抗癌先导化合物。

A 6,6′-dimethyl substitution pattern in Lanchor in [Cu(Lanchor)(Lancillary)]+ dyes in DSCs is superior to two phenyl groups, even when steric crowding is alleviated by using asymmetric Lancillary.

benzaldehyde. The structure of the compound has been confirmed by spectroscopic techniques. Interaction of chalcone with different metal cations was analyzed based on the fluorescencebehavior. Results show that chalcone act as on-offswitching fluorescent chemosensor for selective and sensitive detection iron metal ion.
