Metachromins are a series of sesquiterpenoid quinones isolated from Okinawan marine sponges. Inhibitory effects of metachromins L–Q (1–6), sesquiterpenoid quinones with an amino acid residue, and their related analogs (7–18) prepared from metachromins A (19) and C (20) against receptor tyrosine kinases EGFR and HER2 were investigated. Two analogs 11 and 12 showed relatively stronger inhibitory activity
变色蛋白是从冲绳海洋海绵中分离出来的一系列倍半萜醌。由变色素A(19)和C(20)制备的变色氨酸LQ (1至6),具有氨基酸残基的倍半萜醌及其相关类似物(7至18)对受体酪氨酸激酶EGFR和HER2的抑制作用为。调查。两个类似物11和12显示针对EGFR相对较强的抑制活性,而metachromins L-Q(1 - 6)和七个类似物(8,10,11,和15– 18)表现出对HER2的抑制活性。
