  Benzothiazoles: Search for anticancer agents

  摘要：

  Novel derivatives of 2-amino benzothiazoles 4(a-j) have been synthesized and tested for their antitumor activity using National Cancer Institute (NCI) disease oriented antitumor screen protocol against nine panel of cancer cell lines. Among the synthesized compounds, two compounds were granted NSC code and screened at National Cancer Institute (NCI)-USA for anticancer activity at a single high dose (10(-5) M) and five dose in full NCI 60 cell panel. Among the selected compounds,7-chloro-N-(2,6-dichlorophenyl) benzo[d]thiazol-2-amine (4i) with GI(50) values of 7.18 x 10(-8) M against Non-Small Cell HOP-92 Lung Cancer cell line proved to be the most active members in this study. Virtual screening was carried out through docking the designed compounds into the ATP binding site of epidermal growth factor receptor (EGFR) to predict if these compounds have analogous binding mode to the EGFR inhibitors.

  We have developed the continuous-flow synthesis of thioureas in a multicomponent reaction starting from isocyanides, amidines, or amines and sulfur. The aqueous polysulfide solution enabled the application of sulfur under homogeneous and mild conditions. The crystallized products were isolated by simple filtration after the removal of the co-solvent, and the sulfur retained in the mother liquid. Presenting

  我们已经开发出以异氰化物、脒或胺和硫为原料的多组分反应中硫脲的连续流动合成。多硫化物水溶液能够在均匀和温和的条件下应用硫磺。除去共溶剂后，通过简单过滤分离结晶产物，硫保留在母液中。通过该程序合成的各种硫脲证实了硫的方便连续流应用的实用性。

  The development of a new three‐component chromatography‐free reaction of isocyanides, amines and elemental sulfur allowed us the straightforward synthesis of thioureas in water. Considering a large pool of organic and inorganic bases, we first optimized the preparation of aqueous polysulfide solution from elemental sulfur. Using polysulfide solution, we were able to omit the otherwise mandatory chromatography

  异氰化物、胺和元素硫的新型三组分无色谱反应的开发使我们能够在水中直接合成硫脲。考虑到大量的有机和无机碱，我们首先优化了从元素硫制备多硫化物水溶液的方法。使用多硫化物溶液，我们能够省略原本必须进行的色谱法，并通过简单的过滤直接从反应混合物中分离结晶产物，将硫保留在溶液相中。以这种方式合成的各种硫脲证实了我们的方案的合理底物和官能团耐受性。

The catalytically active C–H activated intermediate dimeric Pd complex was isolated and characterized which on exposure to CO gas gave the corresponding tetrazole fused quinazolinone derivative. On the basis of isolation of the intermediate and observed kinetic isotope effects, a mechanism has been proposed for the C–H activated direct carbonylative
