Eighteen novel 3-substituted-indolin-2-ones containing chloropyrroles were synthesized and their biological activities were evaluated. The presence of a chlorine atom on the pyrrole ring was crucial to reduce cardiotoxicity. The presence of a 2-(ethyl-amino)ethylcarbamoyl group as a substituent at the C-4′ position of the pyrrole enhanced the antitumor activities notably. IC50 values as low as 0.32, 0.67, 1.19 and 1.22 μM were achieved against non-small cell lung cancer (A549), oral epithelial (KB), melanoma (K111) and large cell lung cancer cell lines (NCI-H460), respectively.
合成了十八种含有氯吡咯的3-取代吲哚-2-酮,并评估了它们的生物活性。吡咯环上氯原子的存在对降低心脏毒性至关重要。将2-(乙基氨基)乙基氨基甲酰基团作为取代基引入吡咯的C-4′位置显著增强了抗肿瘤活性。针对非小细胞肺癌(A549)、口腔上皮(KB)、黑色素瘤(K111)和大细胞肺癌细胞系(NCI-H460),获得的IC50值分别低至0.32、0.67、1.19和1.22 μM。
