Enantioselective reductive conjugate alkenylation of α,β-enones with keto alkenyl acetates by nickel catalysis

引用

Science China Chemistry 2025年第1期68卷 157-162页

作者： rong-De He Yun-Lei Luo qiu-Quan Pan Qi-Wei Yao Xing-Zhong Shu State Key Laboratory of Applied Organic Chemistry College of Chemistry and Chemical Engineering Lanzhou University

Reactions involving alkenyl acetates offer cost-effective and environmentally friendly routes for alkene synthesis, yet their asymmetric variant remains elusive. Concurrently, asymmetric conjugate alkenylation predominantly centered on nucleophilic addition using alkenyl–M. This manuscript presents an asymmetric reductive conjugate alkenylation reaction involving alkenyl acetates. The method facilitates the enantioselective addition of keto alkenyl groups to α,β-enones, resulting in the formation of unsaturated diketones—a class of useful structural motifs that are challenging to access otherwise. The use of electron-rich Pyroxy ligand is essential for achieving both high reaction efficiency and enantioselectivity.

The central nervous system, information integration center of the body, is mainly composed of neurons and glial cells. The neuron is one of the most basic and important structural and functional units of the central nervous system, with sensory stimulation and excitation conduction functions. Astrocytes and microglia belong to the glial cell family, which is the main source of cytokines and represents the main defense system of the central nervous system. Nerve cells undergo neurotransmission or gliotransmission, which regulates neuronal activity via the ion channels, receptors, or transporters expressed on nerve cell membranes. Ion channels, composed of large transmembrane proteins, play crucial roles in maintaining nerve cell homeostasis. These channels are also important for control of the membrane potential and in the secretion of neurotransmitters. A variety of cellular functions and life activities, including functional regulation of the central nervous system, the generation and conduction of nerve excitation, the occurrence of receptor potential, heart pulsation, smooth muscle peristalsis, skeletal muscle contraction, and hormone secretion, are closely related to ion channels associated with passive transmembrane transport. Two types of ion channels in the central nervous system, potassium channels and calcium channels, are closely related to various neurological disorders, including Alzheimer's disease, Parkinson's disease, and epilepsy. Accordingly, various drugs that can affect these ion channels have been explored deeply to provide new directions for the treatment of these neurological disorders. In this review, we focus on the functions of potassium and calcium ion channels in different nerve cells and their involvement in neurological disorders such as Parkinson's disease, Alzheimer's disease, depression, epilepsy, autism, and rare disorders. We also describe several clinical drugs that target potassium or calcium channels in nerve cells and could be u

PIG11与热休克蛋白60的相互作用介导肝癌HepG2细胞凋亡

作者：刘小敏胡蓉梁晓秋王晓娟王燕张杨南华大学病理教研室衡阳421001

为了探讨候选肝癌抑癌蛋白PIG11(p53-induced gene11,PIG11)诱导细胞凋亡的机制,首次在HepG2细胞株中鉴定了11个PIG11结合蛋白,热休克蛋白60(heat shock protein60,Hsp60)为其中之一.采用免疫共沉淀联合Western blot技术对Hsp60进行了验证.用Western blot检测其蛋白质表达,结果显示:pLXSN-PIG11-HepG2细胞中Hsp60蛋白表达较pLXSN-HepG2、HepG2细胞组下调(n=3,P<0.01).选取与Hsp60关系密切的Bax蛋白进行研究,Western blot结果显示PIG11高表达可引起胞浆Bax向线粒体转位.以上结果表明,PIG11蛋白能与HepG2细胞中的Hsp60结合,促进Hsp60-Bax的分离,引起Bax从胞液到线粒体转位,激活线粒体凋亡途径,这可能是其诱导HepG2细胞凋亡的主要机制之一.
