reported tyrosol sinapate (4) as a c-Met inhibitor hit. This study reports additional semisynthetic optimization and SAR of 4 to improve its selective activity against c-Met-dependent breast cancer by increasing its capacity to inhibit c-Met phosphorylation. Forty-three compounds (5-47) were synthesized, among which the novel analog homovanillyl sinapate (HVS-16) was distinguished for its remarkable activity
受体酪氨酸激酶c-Met失调及其配体HGF是治疗癌症的有效且有吸引力的分子靶标。受天然存在的橄榄类secrididoid(-)-oleocanthal(1)的化学结构的启发,并记录了其对c-Met依赖性恶性肿瘤的抗癌活性,以前的一项研究报道了酪氨酸溶胶鼻血酸盐(4)作为c-Met抑制剂的命中物。这项研究报告了额外的半合成优化和4的SAR,以通过增加其抑制c-Met磷酸化的能力来提高其对c-Met依赖性乳腺癌的选择性活性。合成了四十三种化合物(5-47),其中新颖的类似物高香草酸芥子酸酯(HVS-16)以其卓越的活性而著称。HVS-16大大削弱了c-Met介导的增殖,迁移,和在二维和三维培养系统中跨越人乳腺癌细胞系的侵袭,而发现相似的治疗剂量既不影响非致瘤性人乳腺上皮细胞的生长,也不影响c-Met独立乳腺癌细胞的生存能力。HVS-16在人乳腺癌细胞中显示出剂量依赖性抑制配体介导的c-Met活
