A library of sixty-five chalcones was prepared for screening against the protein phosphatase, cdc25B. From this library, thirteen compounds were found having good inhibitory activity. Two compounds have excellent activity and can be used for the design of more potent antiproliferative agents.
for the synthesis of [1,4]thiazino[4,3-a]indole derivatives using sodium chlorodifluoroacetate (ClCF2CO2Na) and elemental sulfur as the difluoromethylthiolating reagent system has been developed. Three-component reactions of 2′-aminochalcones, sulfur, and ClCF2CO2Na under basic conditions using TEMPO as the oxidant afforded [1,4]thiazino[4,3-a]indol-10-ones containing a difluoromethyl thioether moiety
已经开发了一种使用氯二氟乙酸钠 (ClCF 2 CO 2 Na) 和元素硫作为二氟甲基硫醇化试剂系统合成 [1,4] 噻嗪并 [4,3- a ] 吲哚衍生物的有效方法。在碱性条件下,使用 TEMPO 作为氧化剂,2'-氨基查耳酮、硫和 ClCF 2 CO 2 Na 的三组分反应得到含有二氟甲基硫醚部分的[1,4] 噻嗪基 [4,3 - a ] 吲哚-10-酮收益良好。在顺序转化过程中选择性地形成四个键,包括一个 C-N、两个 C-S 和一个 C-C 键。

-Enoyl Arylisocyanides: Access to Phenanthridine-8-Carboxylate Derivatives
annulation with glutaconate to provide straightforward access to phenanthridine‐8‐carboxylates and hydrophenanthridine‐8‐carboxylates under mild aerobic conditions. In this domino transformation, two rings and three bonds were successively created. A mechanism involving tandem [3+3]‐annulation/intramolecularcyclization/ demethoxycarbonylation/aerobic oxidative aromatization sequence was proposed.

efficient and straightforward Brønsted-acid mediated cascade process was developed, involving cyclization of readily available β-ketonitriles into 2-aminofurans, and their subsequent recyclization into 2-(1H-indol-2-yl)acetamides is developed. This synthetic route opens a new avenue for an expeditious assembly of various isotryptamine derivatives for medicinal chemistry.

toxicity synergistic antifungal compounds, 24 derivatives of chalcone were synthesized to restore the effectiveness of fluconazoleagainst fluconazole-resistant Candida albicans. The minimal inhibitory concentration (MIC80) and the fractional inhibitory concentration index (FICI) of the antifungalsynergistfluconazole were measured against fluconazole-resistant Candida albicans. This was done via methods
