silico calculations. Method: 1,2,3-triazole aldehydes and acetophenones underwent Claisen-Schmidt reactions to afford four known and six new hybrids, which were identified by spectrometric techniques. In vitro antifungal activities of these compounds against C. lindemuthianum were determined by MIC method. The most active compounds also underwent an assay with common bean plants inoculated with this

Prostate cancer is an important cause of death in the male population and for which there is no satisfactory chemotherapy. Herein a new series of chalcone hybrids containing 2H-1,2,3-triazole core as the ring B has been synthesized and evaluated in vitro against PC-3 prostate cancer cell line. Compounds 4a, 4c and 4e significantly reduced cell viability and showed IC50 of 28.55, 15.64 and 25.56 µM
前列腺癌是男性人群中重要的死亡原因,目前尚无令人满意的化学疗法。本文已经合成了一系列新的查耳酮杂种,其包含2 H -1,2,3-三唑核心作为环B,并在体外针对PC-3前列腺癌细胞系进行了评估。化合物4a,4c和4e显着降低了细胞活力并显示出IC 50分别为28.55、15.64和25.56 µM。计算化学支持的结构-活性关系表明,分子表面积的极性应与化合物的效率有关,特别是部分正电荷位点与暴露于细胞环境的总分子表面积之比。

A simple and fast methodology under microwave irradiation for the synthesis of 2-aminopyrimidine and pyrazole derivatives using Atwal reaction is reported. After the optimization of the reaction conditions, eight 2-aminolpyrimidines containing ferrocene and heterocycles and three ferrocene pyrazoles were synthesized from the respective chalcones in good yields. Eight compounds had their structure determined
报道了一种在微波辐射下使用 Atwal 反应合成 2-氨基嘧啶和吡唑衍生物的简单快速方法。优化反应条件后,8个含二茂铁和杂环的2-氨基嘧啶类化合物和3个二茂铁吡唑类化合物均以良好的收率合成。八种化合物的结构由 X 射线衍射确定。在四种癌细胞系 HCT116、PC3、HL60 和 SNB19 上测试了分子杂交6a-h和9a-c,其中四种嘧啶6a、6f-h和一种吡唑9c衍生物显示出有希望的抗增殖活性。此外,还进行了对接模拟和机器学习方法来解释合成化合物所达到的生物活性。
