the clinical application of PTP1B inhibitors to the prevention and treatment of type 2 diabetes and obesity is expected. During our studies on PTP1B inhibitors, two furanosesterterpenes and a C21 furanoterpene were obtained as new types of PTP1B inhibitors from two Indonesian marine sponges. (7E, 12E, 20Z, 18S)-Variabilin (1) and (12E, 20Z, 18S)-8-hydroxyvariabilin (2) from Ircinia sp. and furospongin-1
蛋白酪氨酸磷酸酶(PTP)1B负调节胰岛素和瘦素的信号通路,因此,PTP1B抑制剂在预防和治疗2型糖尿病和肥胖症中的临床应用是可预期的。在我们对PTP1B抑制剂的研究中,从印尼的两个海洋海绵中获得了两种呋喃酯类萜烯和C21呋喃萜类化合物作为新型PTP1B抑制剂。(7 E,12 E, 20 Z, 18 S)-Variabilin(1)和(12 E, 20 Z,18 S)-8-羟基variabilin(2)来自Ircinia sp。和来自海绵海绵体的furospongin-1(3)sp。抑制PTP1B活性,IC 50值分别为1.5、7.1和9.9μM。化合物1对T细胞PTP(TCPTP)的抑制活性约为对PTP1B的2倍,而牛痘H-1相关磷酸酶(VHR)的抑制作用1比其PTP1B抑制作用弱4倍。活动。化合物1 - 3在50μM未显示出针对两种人癌细胞系的细胞毒性,肝细胞瘤的Huh-7和膀胱癌EJ
