Coelenterazine analogs with different luminescence properties from conventional ones and coelenteramide analogs with different fluorescence properties from conventional ones have been desired. The invention provides coelenterazine analogs modified at the 8-position of coelenterazine and coelenteramide analogs modified at the 2- or 3-position of coelenteramide.

Here, we explore a dehydrogenative 6π photocyclization method for N-substituted naphthalene carboxamides, which can be conducted in air. This method employs DMSO as both the reaction solvent and oxidant while also stabilizing the excited state of the substrate. Furthermore, the addition of photosensitizer enables the reaction to proceed under a 440–445 nm LED source via energy transfer. The proposed
在这里,我们探索了一种N-取代萘甲酰胺的脱氢6π光环化方法,该方法可以在空气中进行。该方法采用DMSO作为反应溶剂和氧化剂,同时稳定底物的激发态。此外,光敏剂的添加使反应能够在 440-445 nm LED 光源下通过能量转移进行。所提出的机制最初通过 DFT 计算得到验证。

1-Alkyl-3-amino-5-aryl-1H-[1,2,4]triazoles: novel synthesis via cyclization of N-Acyl-S-methylisothioureas with alkylhydrazines and their potent corticotropin-Releasing factor-1 (CRF1) receptor antagonist activities

Cyclizations of alkythydrazines with N-acyl-S-methylisothioureas, readily synthesized from acyl chlorides, sodium thioisocyanate. dialkylamines then methyl iodide in a one-pot reaction, gave 1-alkyl-3-dialkylamino-5-phenyltriazoles 7 as major products. The regioisomers were assigned through the use of NOE NMR experiments. While bearing a,N-bis(cyclopropyl)methyl-N-propylamino group, this series of compounds shows very good binding affinity on the human CRF1 receptor. Among them, 1-methyl-3-[N-bis(cyclopropyl)methyl-N-propylamino]-5-(2,4-dichlorophenyl)-1H-[1,2,4]triazole 7a had the best binding affinity for the CRF1 receptor (K-i = 9 nM).
