Chaetocin,来源于球毛壳菌的天然硫基二氧代哌嗪产物,是一个赖氨酸特异性的组蛋白甲基转移酶抑制剂,可以减少SUV39H1的组蛋白甲基转移酶效应,IC50值为0.8 μM。
SUV39H1是组蛋白甲基转移酶,可以甲基化组蛋白H3的赖氨酸9,在许多过程中发挥着重要功能,包括对MYOD1刺激的分化的抑制、细胞周期的调节、细胞分化以及端粒长度的调节。
Chaetocin在一些癌细胞中具有凋亡效应。在患者的CD138 +骨髓瘤细胞中,chaetocin具有较强的抗骨髓瘤活性,这是通过对氧化还原酶硫氧还蛋白还原酶的抑制所诱导的活性氧(ROS)来发挥作用的[1]。Chaetocin减少HL-60和KG-1a细胞中H3K9和H3K27的甲基化[2]。
Chaetocin也被用在动物模型中来研究SUV39H1的作用。Chaetocin在小鼠骨髓瘤异种移植物模型表现出抗增殖活性和抗癌作用[3]。
