Abstract
A new series of tetrasubstituted imidazole carrying sulfonamide as zinc-anchoring group has been designed. The structures of the synthesized derivatives 5 a-l have been confirmed by spectroscopic analysis. These compounds incorporate an ethylenic spacer between the benzenesulfonamide and the rest of the trisubstituted imidazole moiety and were tested as inhibitors of carbonic anhydrases and for in-vitro cytotoxicity. Most of them act as effective inhibitors of the tumor-linked CA isoforms IX and XII, in nanomolar range. Also, different compounds have shown selectivity in comparable with the standard acetazolamide. Our IBS 5 d, 5 g, and 5 l (with Ki: 10.1, 19.4, 19.8 nM against hCA IX and 47, 45, 20 nM against hCA IX) showed the best inhibitory profile. In-vitro screening of all derivatives against a full sixty-cell-lined from NCI at a single dose of 10 μM offered growth inhibition of up to 45 %. Compound 5 b has been identified with the most potent cytotoxic activity and broad spectrum. Docking studies have also been implemented and were also in accordance with the biological outcomes. Our SAR analysis has interestingly proposed efficient tumor-related hCAs IX/XII suppression.

Anticancer Activities of Tetrasubstituted Imidazole-Pyrimidine-Sulfonamide Hybrids as Inhibitors of EGFR Mutants. ChemMedChem 2023; 18:e202200641. [PMID: 36754780 DOI: 10.1002/cmdc.202200641] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2022] [Revised: 02/07/2023] [Accepted: 02/08/2023] [Indexed: 02/10/2023]
Abstract
A new series of tetrasubstituted imidazole derivatives carrying pyrimidine sulfonamide pharmacophores has been synthesized and evaluated for their anticancer activities. In-vitro screening of these hybrids against a full 60-cell-line panel at a single dose of 10 μM showed significant growth inhibition of up to 95 %. The most active compound showed in-vitro anticancer activities against (i) abnormal HER2 and (ii) two mutants for EGFR. Apoptotic gene expression revealed that lead compounds induced MCF-7 cell line apoptosis together with considerable change in the Bax/Bcl-2 expression ratio. One lead compound led to a significant cell-cycle S-phase arrest, while another blocked the cell cycle at G1/S-phase causing the accumulation of cells. Docking analysis of these two hybrids adopted the orientation and binding interactions with a higher liability to enter the active side pocket of HER2, L858R, and T790 M, preferable to that of co-crystallized ligands. Modelling simulation was consistent with the acquired biological evaluation.

Design, Synthesis, and Antibacterial Screening of Some Novel Heteroaryl-Based Ciprofloxacin Derivatives as DNA Gyrase and Topoisomerase IV Inhibitors. Pharmaceuticals (Basel) 2021; 14:ph14050399. [PMID: 33922361 PMCID: PMC8145110 DOI: 10.3390/ph14050399] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2021] [Revised: 04/14/2021] [Accepted: 04/19/2021] [Indexed: 11/16/2022] Open
Abstract
A novel series of ciprofloxacin hybrids comprising various heterocycle derivatives has been synthesized and structurally elucidated using 1H NMR, 13C NMR, and elementary analyses. Using ciprofloxacin as a reference, compounds 1-21 were screened in vitro against Gram-positive bacterial strains such as Staphylococcus aureus and Bacillus subtilis and Gram-negative strains such as Escherichia coli and Pseudomonas aeruginosa. As a result, many of the compounds examined had antibacterial activity equivalent to ciprofloxacin against test bacteria. Compounds 2-6, oxadiazole derivatives, were found to have antibacterial activity that was 88 to 120% that of ciprofloxacin against Gram-positive and Gram-negative bacteria. The findings showed that none of the compounds tested had antifungal activity against Aspergillus flavus, but did have poor activity against Candida albicans, ranging from 23% to 33% of fluconazole, with compound 3 being the most active (33% of fluconazole). The most potent compounds, 3, 4, 5, and 6, displayed an IC50 of 86, 42, 92, and 180 nM against E. coli DNA gyrase, respectively (novobiocin, IC50 = 170 nM). Compounds 4, 5, and 6 showed IC50 values (1.47, 6.80, and 8.92 µM, respectively) against E. coli topo IV in comparison to novobiocin (IC50 = 11 µM).

Abstract
Background:
Second generation or “atypical” antipsychotics demonstrate an improved
therapeutic profile over conventional neuroleptics. These are effective in both positive and negative
symptoms of the disease and have a lower propensity to induce adverse symptoms.
Objective:
The main objective of the research was in silico design and synthesis of potential atypical
antipsychotics with combined antiserotonergic / antidopaminergic effect.
Methods:
A one pot synthesis of aryl substituted imidazole derivatives was carried out in green
solvent PEG-400 and the prepared compounds were evaluated for atypical antipsychotic activity in
animal models for dopaminergic and serotonergic antagonism. The compounds were designed
based on their 3D similarity studies to standard drugs and in silico (docking studies) with respect to
5-HT2A and D2 receptors.
Results:
Results from the docking studies with respect to 5-HT2A and D2 receptors suggested a potential
atypical antipsychotic profile for the test compounds. Theoretical ADME profiling of the
compounds based on selected physicochemical parameters suggested an excellent compliance with
Lipinski’s rules. The potential of these compounds to penetrate the blood brain barrier (log BB) was
computed through an online software program and the values obtained for the compounds suggested
a good potential for brain permeation. Reversal of apomorphine induced mesh climbing behaviour
coupled with inactivity in the stereotypy assay indicates antidopaminergic effect and a potential
atypical profile for the test compounds 1-5. Further, the activity of compounds in DOI assay
indicated a 5-HT2 antagonistic profile (5-HT2 antagonism).
Conclusion:
Compound 5 emerged as important lead compound showing combined antidopaminergic
and antiserotonergic (5-HT2A) activity with a potential atypical antipsychotic profile.
