Exploring 6-Azaindole and 7-Azaindole Rings for Developing Cannabinoid Receptor 1 Allosteric Modulators

Introduction and Objective: Org27569 is a prototypical allosteric modulator of the cannabinoid receptor 1 (CB1). It belongs to the indole-2-carboxamide scaffold and has been intensively investigated in pharmacology and in structure-activity relationship (SAR) studies. Although azaindoles are rare in natural products and differ only by the presence of an extra ring nitrogen, they were demonstrated as valuable bioisosteres in many pharmacologically important molecules. To extend the SAR investigation of the indole-2-carboxamide class of CB1 allosteric modulators, azaindole (pyrrolopyridine) rings were used to replace the indole ring of Org27569 analogs to explore the potential of azaindole-2-carboxamides as CB1 allosteric modulators. Using 6- and 7-azaindole in lieu of the indole moiety within this class of CB1 allosteric modulators indeed improved the aqueous solubility. Materials and Methods: We synthesized 6- and 7-azaindole-2-carboxamides and their indole-2-carboxamide counterparts. The molecules were evaluated by [H-3]CP55,940 binding and [S-35]GTP gamma S binding assays for their allosteric modulation of the CB1 receptor. Results: The 7-azaindole-2-carboxamides lost the ability to bind to the CB1 receptor. The 6-azaindole-2-carboxamides (e.g., 3c and 3d) showed markedly reduced binding affinities to the CB1 receptor in comparison with their indole-2-carboxamide counterparts. However, they behaved similarly as indole-2-carboxamides in potentiating the orthosteric agonist binding and inhibiting the orthosteric agonist-induced G-protein coupling. The results indicated that some azaindole scaffolds (e.g., 6-azaindole) are worth further exploration, whereas the 7-azaindole ring is not a viable bioisostere of the indole ring in the Org27569 class of CB1 allosteric modulators.

Annulative pi-extension of indoles and pyrroles with diiodobiaryls by Pd catalysis: rapid synthesis of nitrogen-containing polycyclic aromatic compounds

A palladium-catalyzed one-step annulative -extension (APEX) reaction of indoles and pyrroles that allows rapid access to nitrogen-containing polycyclic aromatic compounds is described. In the presence of palladium pivalate and silver carbonate, diverse indoles or pyrroles coupled with diiodobiaryls in a double direct C-H arylation manner to be transformed into the corresponding -extended compounds in a single step. The newly developed catalytic system enables the use of various pyrroles and indoles as templates with a series of diiodobiaryls to provide structurally complicated and largely -extended nitrogen-containing polycyclic aromatic compounds that are otherwise difficult to synthesize.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 21679-14-1. Formula: C10H12FN5O4.

The Selective N-Functionalization of Indoles via aza-Michael Addition in the Ligand Sphere of a Chiral Nickel(II) Complex: Asymmetric Synthesis of (S)-1H-Indole-Alanine Derivatives

The selective addition of electrophilic C=C double bonds to the N-H bond of indoles is a challenging task due to the high nucleophilicity of indoles at their C3-position. Herein, we report the successful selective intermolecular N-functionalization of various indoles via aza-Michael addition of C=C double bond of a dehydroalanine Schiff base, which takes place in the ligand sphere of a chiral Ni-II complex in the presence of sodium hydride. The resulting hydroaminated Ni-II complexes were isolated in 55-82 % yields with excellent diastereoselectivity (dr > 99:1) (8 examples). And the actual products of interest, namely (S)-2-amino-3-(1H-indol-1-yl)propanoic acids, were subsequently released from the Ni-II complexes via aqueous HCl treatment of the Ni-II complexes and isolated with excellent enantioselectivity (> 99 % ee). The chiral auxiliary [(S)-BPB = (S)-2-(N-benzylprolyl)aminobenzophenone] and Ni-II ions can be easily recovered after the acidic complex cleavage step and reused for the synthesis of the starting Ni-II complex. Moreover, the indole ‘ s preference for nucleophilic attack via its N1- over its C3-position was rationalized by DFT calculations.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 7300-91-6, in my other articles.
