Gas-Chromatographic Enantioseparation of Unfunctionalized Chiral Hydrocarbons: An Overview

of the hydrocarbons, enantiorecognition in the presence of cyclodextrins is ascribed to weak van der Waals forces. Thermodynamic parameters of enantiorecognition between four chiral alkanes and octakis(6-O -methyl-2,3-di-O -pentyl)-γ-cyclodextrin (Lipodex G

一年内两次叫停！康方CD73单抗又“悬”了，PD-1的黄金搭档还香吗？

细胞。它的酶促活性与胞外磷酸酶（CD39）紧密相关，CD39可产生AMP，而AMP是CD73的作用底物 [8]。CD73产生的细胞外腺苷可通过与腺苷受体（A1R、A2AR、A2BR和A3R）相互作用来激活下游G蛋白偶联信号并调节腺苷酸环化酶（AC）活性，或者通过平衡核苷转运蛋白（ENTs）将其转运至细胞内。如图3 所示，腺苷也可以调节磷脂酶C（由A1R，A2BR和A3R激活）、MAP激酶（由所有AR亚型激活），PI3K（由A1R和A3R激活），钾（KATP）和钙通道（由A1R激活）。在腺苷受体调节的众多生理

Cyclodextrin-modified Micellar Electrokinetic Chromatography for Enantioseparations

of compounds. Cyclodextrin-modified micellar electrokinetic chromatography (CD-MEKC) has become an important capillary electrophoresis mode for enantioseparations. Here, we describe an example of a CD-MEKC method using hydroxypropyl-γ-cyclodextrin as chiral
