novel class of 6-indolypyridine-3-carbonitrile derivatives were synthesized and evaluated for antiproliferative activities to establish structure–activity relationship. The synthesis was carried out through one-pot multicomponent reaction of 3-acetylindole, aromatic aldehydes, ethyl cyanoacetate, and ammonium acetate in the presence of piperidine as a catalyst, using a microwave irradiation method
合成了一类新的 6-indolypyridine-3-carbonitrile 衍生物并评估其抗增殖活性以建立结构-活性关系。该合成是由3-乙酰吲哚、芳香醛、氰基乙酸乙酯和乙酸铵在哌啶作为催化剂存在下,采用微波辐射法或传统热法进行一锅多组分反应进行的。随后对化合物13a – e进行氯化,随后在 C 2处用乙二胺对氯基团进行亲核取代吡啶环的位置。评估了这些新型烟腈对人卵巢腺癌 (SK-OV-3)、乳腺腺癌 (MCF-7) 和宫颈腺癌 (HeLa) 细胞的抗增殖活性。在所有化合物中,2-((2-氨基乙基)氨基)-4-芳基-6-吲哚基烟腈系列(15a、15b、15d和15e)对三种癌细胞系均表现出较高的抗增殖活性,IC 50值为4.1– 13.4 μM。
