1,3,4-Oxadiazole-Containing Histone Deacetylase Inhibitors: Anticancer Activities in Cancer Cells
摘要:
We describe 1,3,4-oxadiazole-containing hydroxamates (2) and 2-aminoanilides (3) as histone deacetylase inhibitors. Among them, 2t, 2x, and 3i were the most potent and selective against HDAC1. In U937 leukemia cells, 2t was more potent than SAHA in inducing apoptosis, and 3i displayed cell differentiation with a potency similar to MS-275. In several acute myeloid leukemia (AML) cell lines, as well as in U937 cells in combination with doxorubicin, 3i showed higher antiproliferative effects than SAHA.

A mild and efficientsynthesis of N-acylhydrazones has been developed, applying a simple grindstone procedure, leading to a library of 51 examples exhibiting a broad variety of structural features, 21 of them described for the first time in this paper. This methodology works without any organic solvent under the catalysis of acetic acid at room temperature, promotes the formation of essentially pure

A novel series of 5-(aroylhydrazinocarbonyl)escitalopram (58–84) have been designed, synthesized and tested for their inhibitory potential against cholinesterases. 3-Chlorobenzoyl- (71) was found to be the most potent compound of this series having IC50 1.80 ± 0.11 μM for acetylcholinesterase (AChE) inhibition. For the butyrylcholinesterase (BChE) inhibition, 2-bromobenzoyl- (76) was the most active

A series of trifluoromethyl pyridine derivatives containing1,3,4-oxadiazolemoiety was designed, synthesized and bio-assayed for their insecticidal activity. The result of bio-assays indicated the synthesized compounds exhibited good insecticidal activity against Mythimna separata and Plutella xylostella, most of the title compounds show 100% insecticidal activity at 500 mg L−1 and >80% activity at
设计、合成了一系列含有1,3,4-恶二唑部分的三氟甲基吡啶衍生物,并对其杀虫活性进行了生物测定。生物测定结果表明,合成的化合物对Mythimna separata和Plutella xylostella表现出良好的杀虫活性,大多数标题化合物在 500 mg L -1 时表现出 100% 的杀虫活性,在250 mg L -1时表现出大于 80% 的杀虫活性。两种害虫。化合物E18和E27对Mythimna separata的LC 50值分别为38.5和30.8 mg L -1,接近阿维菌素(29.6 mg L -1); 化合物E5、E6、E9、E10、E15、E25、E26和E27在 250 mg L -1下显示出 100% 的活性,优于毒死蜱 (87%)。提出了具有良好可预测性的 CoMFA 和 CoMSIA 模型,表明苯环 2 位和 4 位具有适当体积的吸电子基团可以增强杀虫活性。
