Novel Sunifiram-carbamate hybrids as potential dual acetylcholinesterase inhibitor and NMDAR co-agonist: simulation-guided analogue design and pharmacological screening. J Enzyme Inhib Med Chem 2022; 37:1241-1256. [PMID: 35484855 PMCID: PMC9067966 DOI: 10.1080/14756366.2022.2068147] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2021] [Revised: 03/15/2022] [Accepted: 04/15/2022] [Indexed: 11/05/2022] Open
Abstract
An efficient method for synthesising NMDAR co-agonist Sunifiram (DM235), in addition to Sunifram-carbamate and anthranilamide hybrids, has been developed in high yields via protecting group-free stepwise unsymmetric diacylation of piperazine using N-acylbenzotiazole. Compounds 3f, 3d, and 3i exhibited promising nootropic activity by enhancing acetylecholine (ACh) release in A549 cell line. Moreover, the carbamate hybrid 3f was found to exhibit higher in vitro potency than donepezil with IC50 = 18 ± 0.2 nM, 29.9 ± 0.15 nM for 3f and donepezil, respectively. 3f was also found to effectively inhibit AChE activity in rat brain (AChE = 1.266 ng/mL) compared to tacrine (AChE = 1.137 ng/ml). An assessment of the ADMET properties revealed that compounds 3f, 3d, and 3i are drug-like and can penetrate blood-brain barrier. Findings presented here showcase highly potential cholinergic agents, with expected partial agonist activity towards glycine binding pocket of NMDAR which could lead to development and optimisation of novel nootropic drugs.

Abstract
Novel 5-amino-1,2,4-triazole derivatives and their cyclized 1,2,4-triazolo[1,5-a]pyrimidine analogues were designed, synthesized and evaluated for their antimicrobial activities. They were tested against five bacterial strains (Methicillin Resistant S. aureus (MRSA), E. coli, K. pneumoniae, A. baumannii and P. aeruginosa) using ciprofloxacin as a positive control and against two fungal strains (C. albicans and C. neoformans) using fluconazole and amphotericin B as positive controls. Compounds 9, 13a and 13b showed high to moderate antifungal activities against candida albicans (MIC values = 4-32 µg/ml), with considerable safety profiles; where no cytotoxicity against human embryonic kidney or red blood cells were detected at concentrations up to 32 µg/mL. Furthermore, compound 9 showed significant inhibitory activity against lansterol 14α-demethylase (IC50 = 0.27 µM), compared to the reference drug fluconazole (IC50 = 0.25 µM). Molecular docking of compound 9 into the active site of the cytochrome P450 enzyme revealed comparable binding modes and docking scores to those of fluconazole. Finally, in silico ADME studies prediction and drug-like properties of these compounds revealed favorable oral bioavailability results.

Abstract
An efficient approach for the synthesis of a series of S-acyl peptides containing internal cysteine residues has been developed and the chemical long-range ligation of these S-acyl peptides via 5-, 8-, 11- and 14-membered cyclic transition states has been investigated. Our results include the first examples of successful isopeptide ligations starting from S-acyl peptides containing non-terminal cysteine residues and indicate that the cyclic transition states studied in this present paper are decreasingly favored in the order of their sizes 5≫14>11≫8.

Abstract
The title compound, C17H17N5O, exists in the zwitterionic form with the amide group deprotonated. The mean planes of the 1,2,4-triazole and N-phenyl rings form a dihedral angle of 39.14 (8)°. The N atom of the amino group adopts a trigonal configuration. Intermoleculat C—H⋯O and C—H⋯N hydrogen bonds occur. In the crystal, molecules are linked into a two-dimensional network parallel to (10) by N—H⋯O and N—H⋯N hydrogen bonds. C—H⋯N contacts are also observed.

Abstract
Rapid progress in the synthetic application of benzotriazole derivatives in the last 20 years has resulted in over 1000 scientific papers on the subject. This fact is reflected in Section 5.01.7, which involves almost a half of the volume of this chapter. The section is arranged according to hybridization of the C-α atom and atomic numbers of the atoms in positions β and γ to allow an easy access to the material of interest. Recent discovery of copper catalysis in [3+2] cycloadditions of azides to acetylenes, the so-called ‘click chemistry’, which boosted application of the 1,2,3-triazole derivatives, especially in medicinal chemistry, is presented in Section 5.01.9. From the point of view of practical applications, Section 5.01.11 is organized according to the number, position, and combination of the substituents at the aromatic rings. Another novel feature that has no precedence in the previous editions of Comprehensive Heterocyclic Chemistry is an addition of triazole and benzotriazole complexes with various transitions metals to Section 5.01.4.
