Acta Crystallogr Sect E Struct Rep Online

Published: February 2008

In the title compound, C(11)H(9)BrN(2)O, the mol-ecules are linked into R(2) (2)(8) dimers by paired N-H⋯O hydrogen bonds and these dimers are further stacked into columns along the c axis by π-π inter-actions between pyrazinone rings [centroid-centroid distance = 3.544 Å; the dihedral angle between the planes of these rings is 7.51 (16)°]. The title compound is a precursor for agents with potential use as pharmaceuticals.

New benzimidazole-indole-amide derivatives as potent α-glucosidase and acetylcholinesterase inhibitors.

Arch Pharm (Weinheim)

January 2025

Endocrinology and Metabolism Research Center, Endocrinology and Metabolism Clinical Sciences Institute, Tehran University of Medical Sciences, Tehran, Iran.

New derivatives 6a-m with benzimidazole-indole-amide scaffold were developed, synthesized, and assessed for potential inhibitory effects on α-glucosidase and acetylcholinesterase (AChE). These compounds were synthesized by various amine derivatives. With the exception of two compounds, the α-glucosidase inhibitory activities of the title derivatives were more than that of the positive control acarbose.
