  Riluzole prodrugs for melanoma and ALS: Design, synthesis, and in vitro metabolic profiling

  摘要：

  Riluzole (1) is an approved therapeutic for the treatment of ALS and has also demonstrated anti-melanoma activity in metabotropic glutamate GRM1 positive cell lines, a mouse xenograft assay and human clinical trials. Highly variable drug exposure following oral administration among patients, likely due to variable first pass effects from heterogeneous CYP1A2 expression, hinders its clinical use. In an effort to mitigate effects of this clearance pathway and uniformly administer riluzole at efficacious exposure levels, several classes of prodrugs of riluzole were designed, synthesized, and evaluated in multiple in vitro stability assays to predict in vivo drug levels. The optimal prodrug would possess the following profile: stability while transiting the digestive system, stability towards first pass metabolism, and metabolic lability in the plasma releasing riluzole. (S)-O-Benzyl serine derivative 9 was identified as the most promising therapeutically acceptable prodrug. (C) 2012 Elsevier Ltd. All rights reserved.

  Pharmaceutical compositions of the invention include substituted riluzole prodrugs useful for the treatment of cancers including melanoma, breast cancer, brain cancer, and prostate cancer through the release of riluzole. Prodrugs of riluzole have enhanced stability to hepatic metabolism and are delivered into systemic circulation by oral administration, and then cleaved to release riluzole in the plasma via either an enzymatic or general biophysical release process.

  该发明的药物组合物包括替代利鲁唑前药，通过释放利鲁唑用于治疗包括黑色素瘤、乳腺癌、脑癌和前列腺癌在内的癌症。利鲁唑的前药具有增强的对肝代谢的稳定性，并通过口服途径输送到全身循环中，然后通过酶促或一般生物物理释放过程在血浆中释放利鲁唑。

  Pharmaceutical compositions of the invention include substituted riluzole pro drugs useful for the treatment of amyotrophic lateral sclerosis (ALS) and related disorders through the release of riluzole, especially to avoid patient to patient variability in first pass, hepatic metabolism promoted by Cyp 1A2. Pro-drugs of riluzole have enhanced stability to hepatic metabolism and are delivered into systemic circulation by oral administration, and then cleaved to release riluzole in the plasma via either an enzymatic or general biophysical release process. The invention further includes pro-drugs of riluzole useful for the treatment of disease states that can be treated with riluzole through the release of riluzole from a pro-drug agent.

  本发明的药物组合物包括替代利鲁唑前药，通过释放利鲁唑，特别是为了避免Cyp 1A2促进的首过肝代谢引起的患者间变异性，用于治疗肌萎缩侧索硬化症（ALS）和相关疾病。利鲁唑的前药具有增强的肝代谢稳定性，并通过口服途径进入系统循环，然后通过酶促或一般生物物理释放过程在血浆中裂解释放利鲁唑。本发明还包括利鲁唑前药，通过释放利鲁唑治疗可以用利鲁唑治疗的疾病状态。
