为了开发有效的细胞毒剂,我们合成了一系列羟吲哚连接的吲哚基-嘧啶衍生物,并通过IR,1 H NMR,13 C NMR和质谱分析对其进行了表征。对所有新合成的目标化合物针对PA-1(卵巢),U-87MG(胶质母细胞瘤),LnCaP(前列腺)和MCF-7(乳腺癌)癌细胞系的细胞毒性潜力进行了评估,其中大多数表现出抑制活性在低摩尔浓度下。值得注意的是,发现化合物8e在所有测试的化合物中最有效,对PA-1细胞的IC 50值为(2.43±0.29μM)。最具活性的细胞毒性化合物8e的影响在PA-1细胞系上评估细胞周期分布,其在G2 / M期表现出细胞周期停滞。此外,a啶橙/溴化乙锭染色和膜联蛋白V结合试验证实,化合物8e可诱导PA-1细胞凋亡。这些初步结果使对合成化合物的进一步研究成为可能,这些化合物旨在开发潜在的细胞毒剂。

The rhodium(III)-catalyzed C−H bond activation and vinylene transfer of enaminones with vinylenecarbonate have been proposed for the synthesis of substituted 1-hydroxy-2-naphthaldehydes in 49–84% yields. Several preliminary mechanistic studies and hydroxyl-directed derivatization reactions of 1-hydroxy-2-naphthaldehydes were also performed. This method offers an alternative approach for the synthesis
A convenient, rapid, and highly selective method for synthesis of new pyrazolo[1,5-<i>a</i>]pyrimidines via the reaction of enaminones and 5-amino-1<i>H</i>-pyrazoles under microwave irradiation
Twelve new 7-aryl-3-cyanopyrazolo[1,5-a]pyrimidines (3a-f) and ethyl 7-arylpyrazolo[1,5-a]pyrimidine-3-carboxylates (3g-l) have been conveniently synthesized by the reaction of enaminones with 5-amino-1H-pyrazoles in good yields under microwaveirradiation. With one substituded enaminone, only one regioiso-mer was obtained. The structures of new compounds were fully confirmed by elemental analysis
