El-Helw EAE, Asran M, Azab ME, Helal MH, Alzahrani AYA, Ramadan SK. Synthesis and in silico studies of certain benzo[f]quinoline-based heterocycles as antitumor agents. Sci Rep 2024; 14:15522. [PMID: 38969677 PMCID: PMC11226639 DOI: 10.1038/s41598-024-64785-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2024] [Accepted: 06/13/2024] [Indexed: 07/07/2024] Open
Abstract
A series of benzoquinoline-employing heterocycles was synthesized by treating 3-chlorobenzo[f]quinoline-2-carbaldehyde with N-phenyl-3-methylpyrazolone, 4-aminoacetophenone, 1,2-diaminoethane, and 2-cyanoethanohydrazide. Also, pyridine, chromene, α,β-unsaturated nitrile, thiosemicarbazone, and 1,2-bis-aryl hydrazine derivatives were prepared from the cyanoethanohydrazone obtained. The DFT calculations and experiment outcomes were consistent. In vitro screening of their antiproliferative efficacy was examined against HCT116 and MCF7 cancer cell lines. The pyrazolone 2 and cyanoethanohydrazone 5 derivatives exhibited the most potency, which was demonstrated by their molecular docking towards the CDK-5 enzyme. The binding energies of compounds 2 and 5 were - 6.6320 kcal/mol (with RMSD of 0.9477 Å) and - 6.5696 kcal/mol (with RMSD of 1.4889 Å), respectively, which were near to that of co-crystallized ligand (EFP). This implies a notably strong binding affinity towards the CDK-5 enzyme. Thus, pyrazolone derivative 2 would be considered a promising candidate for further optimization to develop new chemotherapeutic agents. In addition, the ADME (absorption, distribution, metabolism, and excretion) analyses displayed its desirable drug-likeness and oral bioavailability properties.

Abstract
Among sulfur-including heterocycles, the benzothiophene skeleton is one of the worthy structure fragments that exhibit structural similarities with active substrates to develop various potent lead molecules in drug design. Thus, some tetrahydrobenzo[b]thiophene candidates were prepared from the β-enaminonitrile scaffold via reactions with diverse carbon-centered electrophilic reagents and supported with DFT studies. The in vitro antiproliferative effect was screened against MCF7 and HePG2 cancer cell lines, and the results displayed the highest potency of imide 5, Schiff base 11, and phthalimido 12 candidates. A molecular docking study was operated to explore the probable binding modes of interaction, and the results revealed the good binding affinity of compounds 5, 11, and 12 toward the tubulin protein (PDB ID 5NM5) with respect to paclitaxel (a tubulin inhibitor) and co-crystallized ligand (GTP). Besides, modeling pharmacokinetics analyses displayed their desirable drug-likeness and bioavailability properties.

RSC Adv 2024; 14:18011-18063. [PMID: 38847003 PMCID: PMC11155445 DOI: 10.1039/d4ra02567a] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2024] [Accepted: 05/29/2024] [Indexed: 06/09/2024] Open
Abstract
Acyl thioureas represent a privileged moiety with vast potential applicability across diverse fields, making them the subject of extensive research efforts. The inherent flexibility of thiourea facilitates the synthesis of a wide range of core structures with diverse functionalities and properties. The distinctive presence of hard and soft donor sites renders acyl thioureas inclined to act as versatile ligands, thereby engendering a diverse array of metal complexes incorporating acyl thiourea as a pivotal ligand. Extensive investigations into the synthesized acyl thioureas and their derivatives have culminated in the elucidation of their substantial potential across a spectrum of applications, spanning biological activities, materials chemistry, catalysis, and beyond. This literature review represents a continuation of our ongoing endeavor to compile comprehensive data on research endeavors concerning acyl thioureas over the past two years.

Elgubbi AS, El-Helw EAE, Alzahrani AYA, Ramadan SK. Synthesis, computational chemical study, antiproliferative activity screening, and molecular docking of some thiophene-based oxadiazole, triazole, and thiazolidinone derivatives. RSC Adv 2024; 14:5926-5940. [PMID: 38362078 PMCID: PMC10867554 DOI: 10.1039/d3ra07048d] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Accepted: 02/07/2024] [Indexed: 02/17/2024] Open
Abstract
Thiophene-2-carbohydrazide was used in this study to produce some thiophene-containing oxadiazole, triazole, and thiazolidinone derivatives through reactions with various carbon-centered electrophiles. Besides, the hydrazone obtained was allowed to react with mercaptoacetic acid and acetic anhydride to construct thiazolidinone and oxadiazole derivatives. The results of computational chemical study and outcomes of the experiments were in good agreement. The in vitro antiproliferative activity of the produced compounds was examined against two human cell lines namely, breast adenocarcinoma (MCF7) and colon cancer (HCT116) cell lines using doxorubicin as a reference anticancer agent. The produced hydrazones and spiro-indolin-oxadiazole derivatives were the most potent against the two cancer cell lines. The molecular docking was conducted to demonstrate the binding energies of produced substances toward human carbonic anhydrase IX (CA IX) protein. The binding energies of these ligands were near to that of the co-crystallized ligand (9FK). Compound 11b exhibits a binding energy of -5.5817 kcal mol-1, indicating tight binding to some key nucleobases and amino acids of CA IX protein, while compound 11a displays a higher binding energy compared to the reference ligand (9FK). This suggests that compounds 11b and 11a display a notably strong binding affinity towards the human carbonic anhydrase IX (CA IX) protein. ADME profiles of the potent compounds including physicochemical characteristics, lipophilicity, and drug-likeness were predicted.

Sci Rep 2023; 13:15093. [PMID: 37699954 PMCID: PMC10497682 DOI: 10.1038/s41598-023-41970-0] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2023] [Accepted: 09/04/2023] [Indexed: 09/14/2023] Open
Abstract
In this study, we aimed to develop hybrid antitumor compounds by synthesizing and characterizing novel N-substituted acrididine-1,8-dione derivatives, designed as hybrids of phthalimide and acridine-1,8-diones. We employed a three-step synthetic strategy and characterized all compounds using IR, 1H NMR, 13C NMR, and LC-MS. The cytotoxicity and antitumor activity of five compounds (8c, 8f, 8h, 8i, and 8L) against four cancer cell lines (H460, A431, A549, and MDA-MB-231) compared to human skin fibroblast cells were evaluated. Among the synthesized compounds, compound 8f showed promising activity against skin and lung cancers, with favorable IC50 values and selectivity index. The relative changes in mRNA expression levels of four key genes (p53, TOP2B, p38, and EGFR) in A431 cells treated with the five synthesized compounds (8c, 8f, 8h, 8i, and 8L) were also investigated. Additionally, molecular docking studies revealed that compound 8f exhibited high binding affinity with TOP2B, p38, p53, and EGFR, suggesting its potential as a targeted anticancer therapy. The results obtained indicate that N-substituted acrididine-1,8-dione derivatives have the potential to be developed as novel antitumor agents with a dual mechanism of action, and compound 8f is a promising candidate for further investigation.
