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 series of α-alkoxy carbamates that cleave under mild conditions to release alcohols has been synthesized through a multicomponent process. The relationship between structural features in these compounds and the rate of alcohol release in the presence of basic hydrogen peroxide has been studied. The preparation of carbamates that cleave under other conditions has been demonstrated.

Para C-H borylation (CHB) of tetraalkylammonium sulfates and sulfamates have been achieved using bipyridne-ligated Ir boryl catalysts. Selectivities can be modulated both by the length of the alkyl groups in the tetraalkylammonium cations and the substituents on the bipyridine ligands. Ion-pairing, where the alkyl groups of the cation shield the meta C-H bonds in the conteranions, is proposed to account
四烷基硫酸铵和氨基磺酸盐的对位 CH 硼化 (CHB) 已使用联吡啶连接的 Ir boryl 催化剂实现。选择性可以通过四烷基铵阳离子中烷基的长度和联吡啶配体上的取代基来调节。离子对,其中阳离子的烷基屏蔽了对位离子中的间位 CH 键,被认为是对位选择性的原因。4,4'-二甲氧基-2,2'-联吡啶配体具有优异的选择性。
