Design and synthesis of a new series of quinolinylaminoisoquinoline derivatives as conformationally restricted bioisosteres of Sorafenib are described. Their in vitro antiproliferative activity against A375P melanoma cell line was tested. Compounds 1b, 1d, 1g, and 1j showed the highest potency against A375P cell line with IC50 values in sub-micromolar scale. In addition, compound 1d exerted high selectivity towards RAF1 serine/threonine kinase with 96.47% inhibition at 10 µM, and IC50 of 0.96 µM. This compound can possess antiproliferative activity against melanoma cells through inhibition of RAF1 kinase.
报道了一种新型喹啉基氨基异喹啉衍生物的设计与合成,这些衍生物作为索拉非尼的构象限制性生物等排体。测定了它们对A375P黑色素瘤细胞系的体外抗增殖活性。化合物1b、1d、1g和1j显示出对A375P细胞系最高的活性,IC50值在亚微摩尔范围内。此外,化合物1d对RAF1丝氨酸/苏氨酸激酶表现出高选择性,在10微摩尔浓度下抑制率达到96.47%,IC50为0.96微摩尔。该化合物通过抑制RAF1激酶对黑色素瘤细胞具有抗增殖活性。
