Morita-Baylis-Hillman acetates and α-bromonitroalkenes have been employed in cascade reactions with lawsone and 2-aminonaphthoquinone for the one-pot synthesis of heterocycle fused quinonoid compounds. The reactions reported here utilized the 1,3-binucleophilic potential of hydroxy- and aminonaphthoquinones and the 1,2/1,3-bielectrophilic potential of bromonitroalkenes and Morita-Baylis-Hillman acetates
Morita-Baylis-Hillman乙酸盐和α-溴硝基烯烃已用于与Lawone和2-氨基萘醌的级联反应,用于一锅合成杂环稠合的醌类化合物。此处报道的反应利用羟基和氨基萘醌的1,3-双亲核势以及溴硝基烯烃和Morita-Baylis-Hillman乙酸酯的1,2 / 1,3-双亲电势来合成吡咯和呋喃稠合的萘醌。对合成的化合物针对HCT-116(人类结肠癌细胞),PC3(人类前列腺癌细胞),HL-60(人类早幼粒细胞白血病细胞),SF295(人类胶质母细胞瘤细胞)和NCI-H460(人类肺癌细胞)进行了评估。并显示出抗肿瘤活性,IC50值低至<2μM。还针对OVCAR-8(卵巢)评估了选定的化合物,MX-1(乳腺癌)和JURKAT(白血病)细胞系。还使用非肿瘤细胞测定了评价的醌类的细胞毒性潜力,例如外周血单核(PBMC)和L929细胞。
