RO4987655是MEK高选择性的小分子抑制剂,IC50值为5 nM[1].
RO4987655在5位有一个独特的3-oxo-[1,2]oxazinan-2-ylmethyl 基团.相对其他400种激酶,RO4987655对MEK具有高选择性.同时,RO4987655是MEK的非竞争性抑制剂.在ATP缺乏或存在时都对MEK具有较高的亲和力.RO4987655对多种肿瘤细胞都有很强的抗增殖作用,包括COLO205\HT29\QG56\MIA和C32,IC50值分别为0.86 nM\1.7 nM\9.5 nM\3.3 nM和8.4 nM.此外,RO4987655被发现在多种人类肿瘤异种移植模型中都具有抗肿瘤活性.在HT-29人结肠癌异种移植物中,RO4987655强烈抑制pERK的形成,引起肿瘤消退[ 1,2 ].
RO4987655正在进行I期临床试验.试验表明,RO4987655对BRAF野生型黑色素瘤和BRAF V600突变型黑色素瘤的患者都有临床活性.它也对KRAS突变的非小细胞肺癌患者有效,但对KRAS突变的结直肠癌无效[ 2 ].
