ARQ 621是Eg5的新型、变构、强效的选择性抑制剂。Eg5属于有丝分裂驱动蛋白超家族,在有丝分裂中起着关键作用。Eg5对有丝分裂纺锤体的组织至关重要。过表达Eg5会导致基因组不稳定和肿瘤形成[1]。
体外实验:在人肝微粒中,ARQ 621的t1/2为53分钟。在雄性和雌性小鼠、大鼠、狗和猴的肝微粒中,ARQ 621的t1/2值分别为43、53、56、53、47、44、36和32分钟[1]。对于CYP 1A2、2C9、2D6、3A4、2C19和2C8 ARQ 621的IC50值分别为 > 20、> 20、> 20、4.1、4.0和15 μM。在一系列人类实体和血液恶性肿瘤细胞如结肠癌、非小细胞肺癌、胃癌和血液学癌症细胞系中,低纳摩尔范围的ARQ 621显示抗肿瘤活性[1]。
在体实验:ARQ 621的口服给药显示,ARQ 621的生物利用度约为9%[1]。
临床试验:ARQ 621目前正在癌症患者中进行I期临床试验。10 mg/m2/week 的ARQ 621静脉给药超过1-2小时,95.9%的患者出现了副作用。主要的副作用是疲劳、急性血管内溶血和腹痛。每周280 mg/m2剂量的ARQ 621耐受性良好 [2,3]。
