Molecules 2021; 26:molecules26175135. [PMID: 34500565 PMCID: PMC8433848 DOI: 10.3390/molecules26175135] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2021] [Revised: 07/30/2021] [Accepted: 07/31/2021] [Indexed: 12/02/2022] Open
Abstract
N-acyl homoserine lactones (AHLs) are small signaling molecules used by many Gram-negative bacteria for coordinating their behavior as a function of their population density. This process, based on the biosynthesis and the sensing of such molecular signals, and referred to as Quorum Sensing (QS), regulates various gene expressions, including growth, virulence, biofilms formation, and toxin production. Considering the role of QS in bacterial pathogenicity, its modulation appears as a possible complementary approach in antibacterial strategies. Analogues and mimics of AHLs are therefore biologically relevant targets, including several families in which heterocyclic chemistry provides a strategic contribution in the molecular design and the synthetic approach. AHLs consist of three main sections, the homoserine lactone ring, the central amide group, and the side chain, which can vary in length and level of oxygenation. The purpose of this review is to summarize the contribution of heterocyclic chemistry in the design of AHLs analogues, insisting on the way heterocyclic building blocks can serve as replacements of the lactone moiety, as a bioisostere for the amide group, or as an additional pattern appended to the side chain. A few non-AHL-related heterocyclic compounds with AHL-like QS activity are also mentioned.

Design, green one-pot synthesis and molecular docking study of novel N,N-bis(cyanoacetyl)hydrazines and bis-coumarins as effective inhibitors of DNA gyrase and topoisomerase IV. Bioorg Chem 2020; 97:103672. [PMID: 32145481 DOI: 10.1016/j.bioorg.2020.103672] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2019] [Revised: 01/24/2020] [Accepted: 02/14/2020] [Indexed: 12/15/2022]
Abstract
A novel, quick, environmentally safe, and one-pot synthesis of a series of N,N-bis(cyanoacetyl)hydrazine derivatives, bis-imino-2H-chromenes and bis-2-oxo-2H-chromene derivatives have been designed. Some selected newly synthesized compounds were investigated in vitro for their antibacterial activity. Compound 5j is the most toxic compound against Staphylococcus aureus with activity index 171%, followed by compound 15b with activity index 136% compared to standard drug ampicillin. Moreover, compound 15a is the most toxic compound against Escherichia coli with activity index 111% compared to standard drug gentamicin. Minimum inhibitory concentration (MIC) was carried out for compounds with high antibacterial activity. Compound 5j has good MIC (7.8 μg/ml) against Staphylococcus aureus while 15a has good MIC (31.25 μg/ml) against Streptococcus mutans which is better than MIC of the standard drug ampicillin (MIC = 62.5 μg/ml). Compounds 5j, 5k, 15a, 15b and 15e which have good MIC values were introduced to enzyme assay against DNA gyrase and topoisomerase IV. The results showed that compound 15a can strongly inhibit DNA gyrase and topoisomerase IV (IC50 = 27.30 and 25.52 μM respectively), compared to methotrexate as the standard drug (IC50 = 29.01 and 23.55 μM respectively). Structure-activity relationships were also discussed based on the biological and docking simulation results.
