Malignant gliomas, including glioblastomas, are extremely difficult to treat. The median survival for glioblastoma patients with optimal therapeutic intervention is 15 months. We developed a novel MAO‐B‐selectively activated prodrug, N,N‐bis(2‐chloroethyl)‐2‐(1‐methyl‐1,2,3,6‐tetrahydropyridin‐4‐yl)propanamide (MP‐MUS), for the treatment of gliomas based on 1‐methyl‐4‐phenyl‐1,2,3,6‐tetrahydropyridine
恶性神经胶质瘤,包括胶质母细胞瘤,极难治疗。胶质母细胞瘤患者采用最佳治疗干预后的中位生存期为15个月。我们开发了一种新型的MAO-B选择性活化的前药N,N-双(2-氯乙基)-2-(1-甲基-1,2,3,6-四氢吡啶-4-基)丙酰胺(MP-MUS) ,用于治疗基于1-甲基-4-苯基-1,2,3,6-四氢吡啶(MPTP)的神经胶质瘤。中性MP-MUS的设计涉及使用能够与线粒体MAO-B结合的搜寻分子,该分子在神经胶质瘤细胞中被上调≥4倍。一旦结合发生,MP-MUS就会转换为带正电的部分P + -MUS,该线粒体内的线粒体以理论最大值1000:1的梯度累积。LD 50针对神经胶质瘤细胞MP-MUS的是75μ中号,这是两到三倍替莫唑胺相比更有效,对神经胶质瘤的主药。重要的是,发现MP-MUS对神经胶质瘤细胞有选择性毒性。在150-180的浓度范围μ中号MP-MUS杀死神经胶质瘤细胞的90-95%,
