  摘要：

  A series of novel 10-((1H-indol-3-yl)methylene)-7-aryl-7,10-dihydro-5H-benzo[h]thiazolo[2,3-b]quinazolin-9(6H)-ones (8a-t) have been synthesized in good yields by the reaction of benzo[h]quinazoline-2(1H)-thiones (4a-f) with 2-chloro-N-phenylacetamide (5) followed by Knoevenagel condensation with various indole-3-carbaldehydes (7a-d) under conventional method. All the synthesized compounds were characterized by spectral studies and screened for their in vitro anticancer and antimicrobial activities. Compound 8c has exhibited excellent activity against MCF-7 (breast cancer cell line) than the standard drug Doxorubicin. Compound 8d against both the cancer cell lines, 8q against MCF-7 and 8c, 8h against HepG2 have also shown good activity. Remaining compounds have shown moderate activity against both the cell lines. Antimicrobial activity revealed that, the compound 8q and 8t against Staphylococcus aureus and 8i, 8k, 8l, 8q &8t against Klebsiella pneumoniae have shown equipotent activity on comparing with the standard drug Streptomycin. Remaining compounds have shown significant antibacterial and comparable antifungal activities against all the tested microorganisms.

  新型潜在Bcl-x L抑制剂喹唑啉-2（1 H）-硫酮衍生物的设计，合成及相互作用研究

  摘要：

  拮抗抗凋亡的Bcl-2家族蛋白活性的抑制剂的开发在癌症化学疗法中尤为重要。通过虚拟数据库筛选，我们发现了一种喹唑啉-2（1 H）-硫酮衍生物（DCBL55）作为新的Bcl-x L，Bcl-2和Mcl-1抑制剂。我们通过化学合成系统地修饰了化合物1的结构。通过分子模拟模拟预测了化合物与Bcl-x L的相互作用，并通过结构-活性关系分析和蛋白质突变研究证实了这一点。Bcl-x L疏水槽的三个位置发现被称为P2，P4和P5的P2，P4和P5有助于配体相互作用。尽管该化合物诱导线粒体电位降低，半胱天冬酶激活和ROS产生，但细胞毒性和线粒体外膜的超微结构变化表明该化合物可能靶向Bcl-2家族以外的其他蛋白质。总之，本研究提供了新的先导化合物和重要的结构信息，以进一步开发抗凋亡Bcl-2家族蛋白的更强效和特异性抑制剂。

  2-Chloro-N-phenylacetamide and N-(benzo[d]thiazol-2-yl)-2-chloroacetamide are doubly electrophilic building blocks for the formation of ring annulated thiazolo[3,2-a]pyrimidinone products. This synthetic route involves formation of the title compound in acceptable product yields by the elimination of the by-product, aniline/2-aminobenzothiazole. Analytical and spectral studies, as well as single crystal

  日期：——

  A rapid and efficient one pot solvent/scavenger-free protocol for the synthesis of 2-iminothiazolidin-4-ones has been developed. Interestingly, the regio/stereoselective synthesis affords the regioisomeric (Z)-3-alkyl/aryl-2-(2-phenylcyclohex-2-enylimino)thiazolidin-4-one as the sole product in good yield. The selectivities observed have been rationalized based on the relative magnitude of the allylic strains developed during the course of the reaction. This is the first report wherein the impact of allylic strains in directing the regiocyclization has been noted.

  已经开发了一种快速高效的单锅无溶剂/清除剂合成2-亚氨基噻唑啉-4-酮的方案。有趣的是，区域/立体选择性合成只产生区异构体(Z)-3-烷基/芳基-2-(2-苯基环己-2-烯基亚氨基)噻唑啉-4-酮，收率良好。观察到的选择性是基于反应过程中产生的联烯应变相对大小的合理化。这是第一篇注意到联烯应变对定向区域环化的影响的报告。
