  Optimization of Chemical Functionalities of Indole-2-carboxamides To Improve Allosteric Parameters for the Cannabinoid Receptor 1 (CB1)

  摘要：

  5-Chloro-3-ethyl-N-(4-(piperidin-1-yl)phenethyl)-1H-indole-2-carboxamide (1; ORG27569) is a prototypical allosteric modulator for the cannabinoid type I receptor (CBI). Here, we reveal key structural requirements of indole-2-carboxamides for allosteric modulation of CBI: a critical chain length at the C3-position, an electron withdrawing group at the CS-position, the length of the linker between the amide bond and the phenyl ring B, and the amino substituent on the phenyl ring B. These significantly impact the binding affinity (K-B) and the binding cooperativity (alpha). A potent CB1 allosteric modulator 5-chloro-N-(4(dimethylamino)phenethyl)-3-propyl-1H-indole-2-carboxamide (12d) was identified. It exhibited a K-B of 259.3 nM with a strikingly high binding alpha of 24.5. We also identified 5-chloro-N-(4-(dimethylamino)phenethyl)-3-hexyl-1H-indole-2-carboxamide (120 with a K-B of 89.1 nM, which is among the lowest K-B values obtained for any allosteric modulator of CB1. These positive allosteric modulators of orthosteric agonist binding nonetheless antagonized the agonist-induced G-protein coupling to the CB1 receptor, yet induced beta-arrestin mediated ERK/2 phosphorylation.

  Photocatalysis enables the cascade reactions of indoles and CBr4 in MeOH through a C(sp2)H functionalization/methanolysis sequence. The title reaction provides an efficient access to indole 2‐ and 3‐carboxylates in a single operation (no preinstallation of protecting as well as directing groups was required) with good yields under mild reaction conditions.

  光催化通过C（sp 2）H官能化/甲烷分解序列实现吲哚和CBr 4在MeOH中的级联反应。标题反应可在温和的反应条件下以高收率在一次操作中高效获得吲哚2和3-羧酸酯（无需预先安装保护基团和导向基团）。
