potentiated the anticancer activity and NF-κB inhibitory activity, respectively. However, according to the results of structure–activity relationship studies, only benzofuran-2-carboxylic acid N-(4′-hydroxy)phenylamide (3m) was the lead scaffold with both an outstanding anticancer activity and NF-κB inhibitory activity. This novel lead scaffold may be helpful for investigation of new anticancer agents that act
为了开发新型支架作为抗癌剂和NF-κB活性抑制剂,开发了60种新颖的苯并呋喃和2,3-二氢苯并呋喃-2-羧酸N-(取代)苯酰胺衍生物(1a - s,2a - k,3a – s和4a – k)是由参考铅化合物KL-1156设计和合成的,它是LPS刺激的RAW 264.7巨噬细胞中NF-κB易位至细胞核的抑制剂。新型苯并呋喃-和2,3-二氢苯并呋喃-2-羧酰胺衍生物在低微摩尔浓度下对六种人类癌细胞系表现出强力的细胞毒性活性(通过磺基罗丹明B测定):ACHN(肾),HCT15(结肠),MM231(乳腺),NUGC-3(胃),NCI-H23(肺)和PC-3(前列腺)。此外,这些化合物还抑制LPS诱导的NF-κB转录活性。N-苯环上的+ M效应和疏水基团分别增强了其抗癌活性和NF-κB抑制活性。然而,根据结构-活性关系研究的结果,只有苯并呋喃-2-羧酸N-(4'-羟基)苯酰胺(3m)是具有出色的抗癌
