A ∼3500-member library of bidentate inhibitors against protein tyrosine phosphatases (PTPs) was rapidly assembled using click chemistry. Subsequent high-throughput screening had led to the discovery of highlypotent (Ki as low as 150 nM) and selectiveMptpBinhibitors, some of which represent the most potentMptpBinhibitors developed to date.

beneficial effects to increase brain acetylcholine amounts resulting in neurocognitive function. In the present article, fifteen small molecules of 1, 4-naphthoquinone conjugated to aryl triazole acetamide derivatives were rationally designed, synthesized, and evaluated for their anti-ChE activities followed by molecular docking assessments. Among synthesized derivatives, 7b bearing ortho-chlorine moiety
阿尔茨海默病是一种神经退行性疾病,会降低心智能力。被命名为乙酰胆碱酯酶和丁酰胆碱酯酶的两种主要胆碱酯酶是针对阿尔茨海默病的潜在靶标。胆碱酯酶抑制剂具有增加脑乙酰胆碱量的有益作用,从而导致神经认知功能。在本文中,15 个与芳基三唑乙酰胺衍生物共轭的 1, 4-萘醌小分子经过合理设计、合成和评估其抗 ChE 活性,然后进行分子对接评估。在合成的衍生物中,含有邻氯部分的7b是乙酰胆碱酯酶和丁酰胆碱酯酶的最强抑制剂,K i与作为阳性对照的 Tacrine 相比,K i = 70.61 和 64.18 nM 的值分别为 10.16 和 8.04 nM。对接研究证实了7b完全适合两种酶的活性位点。

isoxazole-linked benzothiazole/benzoxazole derivatives were synthesized and evaluated for their anticancer activity against human cancer cell lines, such as HeLa (cervical), and A549 (lung) cell lines, with HEK-293 cell line used as a control. Among them, conjugates 8a, 8f, 13g, 13h and 13j displayed significant cytotoxic activity against human cancer cell lines. Furthermore, these active conjugates induced

A new series of fluoro 1,2,3-triazole tagged amino bis (benzothiazole) derivatives 8, 9 were prepared starting from 2-amino benzothiazole in four steps via amination, cyclization, alkylation followed by reaction with various azides under sharpless conditions through click chemistry approach. All newly synthesized compounds were screened for their antimicrobial and cytotoxic activity against four human cancer cell lines (U937, THP-1, Colo205, and A549), and promising compounds have been identified.
