diseases. In the present study, a series of 47 carbamazepine derivatives including 32 novel compounds were designed, synthesized, and evaluated as P2X4 receptor antagonists. Their potency to inhibit ATP-induced calcium influx in 1321N1 astrocytoma cells stably transfected with the human P2X4 receptor was determined. Additionally, species selectivity (human, rat, mouse) and receptor subtype selectivity (P2X4

Herein, an oxygen atom deletion strategy via sequential Pd-catalyzed decarboxylative carbonylation of carbonates and carbamates to afford esters and amides is reported. Operating under lowpressures (near stoichiometric or substoichiometric), either 13C labeled products are accessed or a proof-of-concept that CO2 formed upon decarboxylation can be reduced in situ and reincorporated as CO is shown.
在此,报道了通过碳酸酯和氨基甲酸酯的连续 Pd 催化脱羧羰基化以提供酯和酰胺的氧原子删除策略。在低压(接近化学计量或亚化学计量)下操作,可以获取13 C 标记的产品,也可以证明脱羧时形成的 CO 2可以原位还原并重新结合为 CO。
