vitro and in vivo. The structures of the two conjugates were verified by chemical synthesis, mass spectrometry, and nuclear magnetic resonance. CYP3A4 was found to dominate the hydroxylation of 4-MQ. Sulfotransferases also participated in the metabolicactivation of 4-MQ. Pretreatment of primary hepatocytes with ketoconazole (KTC) or 2,6-dichloro-4-nitrophenol (DCNP) not only reduced the production of
4-Methylquinoline (4-MQ) is a quinoline derivative widely present in groundwater and soil and has been reported to be genotoxic. The mechanisms of the toxic action remain unknown. This study aimed to elucidate the metabolic activation of 4-MQ and to determine the possible role of reactive metabolites in 4-MQ-induced liver injury in rats. In the present study, a hydroxylation metabolite (M1), a GSH
Remote stereocontrol with azaarenes via enzymatic hydrogen atom transfer
Strategies for achieving asymmetriccatalysis with azaarenes have traditionally fallen short of accomplishing remote stereocontrol, which would greatly enhance accessibility to distinct azaarenes with remote chiral centres. The primary obstacle to achieving superior enantioselectivity for remote stereocontrol has been the inherent rigidity of the azaarene ring structure. Here we introduce an ene-reductase
传统上,利用氮杂芳烃实现不对称催化的策略无法实现远程立体控制,而远程立体控制将极大地提高对具有远程手性中心的不同氮杂芳烃的可及性。实现远程立体控制的优异对映选择性的主要障碍是氮杂芳环结构的固有刚性。在这里,我们介绍了一种烯还原酶系统,能够通过手性氢原子转移机制调节氮杂芳烃上远程碳中心自由基的对映选择性。这种光酶过程有效地引导前手性自由基中心位于距离氮杂芳烃中的氮原子超过 6 个化学键或超过 6 Å 的位置,从而能够生产多种具有远程 γ-立构中心的氮杂芳烃。我们综合计算和实验研究的结果强调,关键氨基酸残基的氢键和空间效应对于实现如此高的立体选择性非常重要。
