Synthesis of tritiated N-[4-(2,4-diaminopteridine-6-methyl)-3,4-dihydro-2H-1,4-benzothiazine-7-carbonyl]-L-homo glutamic acid (MX-68)
摘要:
Synthesis of tritiated N-[4-(2,4-diaminopteridine-6-methyl)-3,4-dihydro-2H-1,4-benzothiazine-7-carbonyl]-L-homoglutamic acid, [9-H-3(1)]MX-68 (3), is described. [9-H-3(1)]MX-68 (3) was prepared via tritiation at the carbonyl group in 2,4-bis(butanoylamino)-6-formylpteridine (7) with sodium borotritiide.

A series of novel hydrogen peroxide sensitive prodrugs of methotrexate (MTX) and aminopterin (AMT) were synthesized and evaluated for therapeutic efficacy in mice with collagen induced arthritis (CIA) as a model of chronic rheumatoid arthritis (RA). The prodrug strategy selected is based on ROS-labile 4-methylphenylboronic acid promoieties linked to the drugs via a carbamate linkage or a direct C–N
合成了一系列新的甲氨蝶呤(MTX)和氨蝶呤(AMT)对过氧化氢敏感的前药,并评估了胶原诱导的关节炎(CIA)作为慢性类风湿关节炎(RA)的模型对小鼠的治疗效果。选择的前药策略是基于不稳定的ROS,通过氨基甲酸酯键或直接的C–N键与药物相连的4-甲基苯基硼酸。在病理生理浓度的H 2 O 2下激活被证明是有效的,并且与相关体外实验一致地选择了前药候选物物理化学和药代动力学分析。与CIA模型中的母体药物相比,选定的候选药物显示出中等至良好的溶解度,较高的化学和酶稳定性以及治疗功效。重要的是,与MTX和AMT相比,前药显示出预期的更安全的毒性特征并增加了治疗范围,同时保持了可比的治疗功效,这极大地鼓舞了RA患者的未来使用。

A process for preparation of 4-(1-(2,4-diaminopteridin-6-yl)pent-4-yn-2-yl)benzoic acid and other key intermediates in synthesis of 10-propargyl-10-deazaaminopterin (Pralatrexate) and the intermediates thereof. The 10-propargyl-10-deazaaminopterin (Pralatrexate) is obtained by peptide formation and ester hydrolysis of the intermediate compound 4-(1-(2,4-diaminopteridin-6-yl)pent-4-yn-2-yl)benzoic acid by methods known in the art.
