evaluated for their in vitro cytotoxic activities in five human cancer cell lines, namely, lung cancer (A549), ovarian cancer (SK-OV-3), skin cancer (SK-MEL-2), colon cancer (HCT15) and pancreatic cancer (MIA-PaCa-2) cells, and for their in vitro tropomyosin receptor kinase A (TrkA) inhibitory activities. Each of the compounds showed significant cytotoxicity against all cancer cells. Compound 3i was found
合成了一系列新型水杨酰hydr类似物,并评估了它们在五种人类癌细胞系中的体外细胞毒性活性,这些细胞系分别是肺癌(A549),卵巢癌(SK-OV-3),皮肤癌(SK-MEL- 2),结肠癌(HCT15)和胰腺癌(MIA-PaCa-2)细胞,及其对体外原肌球蛋白受体激酶A(TrkA)的抑制活性。每种化合物对所有癌细胞均显示出显着的细胞毒性。发现化合物3i对所有癌细胞系最有效,IC50值分别为2.46(A549),0.87(SK-OV-3),1.43(SK-MEL-2),0.89(HCT15)和0.48μM(MIA -PaCa-2),然后加入化合物3l。3i对HCT15细胞的细胞毒性类似于阿霉素(0.87μM)。化合物3i和3l也显示出最高的TrkA抑制活性,IC50值分别为0.231和0.380μM。对该系列的SAR研究表明,具有羟基的化合物比化合物具有更好的细胞毒性和TrkA抑制能力(按以下顺序排列,即2
