Abstract
Traditional chemical synthesis, which involves the use of dangerous protocols, hazardous solvents, and toxic products and catalysts, is considered environmentally inappropriate and harmful to human health. Bearing in mind its numerous drawbacks, it has become crucial to substitute conventional chemistry with green chemistry which is safer, more ecofriendly and more effective in terms of time and selectivity. Elaborating synthetic protocols producing interesting new compounds using both microwave heating and heterogeneous non-toxic catalysts is acknowledged as a green approach that avoids many classical chemistry-related problems. In the current study, β-enaminones were used as precursors to the synthesis of modified 4-hydroxy-2-quinolone analogues. The synthesis was monitored in a benign way under microwave irradiation and was catalyzed by bismuth chloride III in an amount of 20 mol%. This method is privileged by using a non-corrosive, non-toxic, low-cost and available bismuth Lewis acid catalyst that has made it more respectful to the demands of green chemistry. The synthesized compounds were obtained in moderate to good yields (51-71%) and were characterized by 1H, 13C NMR, and IR spectroscopy as well as elemental analysis. Compound 5i was subjected to a complete structural elucidation using the X-ray diffraction method, and the results show the obtention of the enolic tautomeric form.

Abstract
A thiazolidine-2,4-dione nucleus was molecularly hybridised with the effective antitumor moieties; 2-oxo-1,2-dihydroquinoline and 2-oxoindoline to obtain new hybrids with potential activity against VEGFR-2. The cytotoxic effects of the synthesised derivatives against Caco-2, HepG-2, and MDA-MB-231 cell lines were investigated. Compound 12a was found to be the most potent candidate against the investigated cell lines with IC50 values of 2, 10, and 40 µM, respectively. Furthermore, the synthesised derivatives were tested in vitro for their VEGFR-2 inhibitory activity showing strong inhibition. Moreover, an in vitro viability study against Vero non-cancerous cell line was investigated and the results reflected a high safety profile of all tested compounds. Compound 12a was further investigated for its apoptotic behaviour by assessing the gene expression of four genes (Bcl2, Bcl-xl, TGF, and Survivin). Molecular dynamic simulations authenticated the high affinity, accurate binding, and perfect dynamics of compound 12a against VEGFR-2.

[PMID: 34631658 PMCID: PMC8493129 DOI: 10.3389/fchem.2021.725135] [Citation(s) in RCA: 40] [Impact Index Per Article: 13.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2021] [Accepted: 07/29/2021] [Indexed: 02/05/2023] Open
Abstract
Guided by the structural optimization principle and the promising anticancer effect of the quinoxaline nucleus, a new series of novel HDAC inhibitors were designed and synthesized. The synthesized compounds were designed to bear the reported pharmacophoric features of the HDAC inhibitors in addition to an extra moiety to occupy the non-used vacant deep pocket of the HDAC receptor. The newly prepared compounds were evaluated for their in vitro anti-proliferative activities against HepG-2 and HuH-7 liver cancer cell lines. The tested compounds showed promising anti-proliferative activities against both cell lines. The most active ten candidates (6 c , 6 d , 6 f , 6 g , 6 k , 6 l , 7 b , 8, 10 h , and 12) were further evaluated for their effect on the gene expression levels of Bax as an apoptotic marker and Bcl-2 as an anti-apoptotic one. Moreover, they were evaluated for their ability to inhibit histone deacetylase (HDAC1, HDAC4, and HDAC6) activities. Compound 6 c achieved the best cytotoxic activities on both HepG-2 and HuH-7 cell lines with IC50 values of 1.53 and 3.06 µM, respectively, and also it showed the most inhibitory activities on HDAC1, HDAC4, and HDAC6 with IC50 values of 1.76, 1.39, and 3.46 µM, respectively, compared to suberoylanilide hydroxamic acid (SAHA) as a reference drug (IC50 = 0.86, 0.97, and 0.93 µM, respectively). Furthermore, it achieved a more characteristic arrest in the growth of cell population of HepG-2 at both G0/G1 and S phases with 1.23-, and 1.18-fold, respectively, compared to that of the control, as determined by cell cycle analysis. Also, compound 6 c showed a marked elevation in the AnxV-FITC apoptotic HepG-2 cells percentage in both early and late phases increasing the total apoptosis percentage by 9.98-, and 10.81-fold, respectively, compared to the control. Furthermore, docking studies were carried out to identify the proposed binding mode of the synthesized compounds towards the prospective target (HDAC4). In silico ADMET and toxicity studies revealed that most of the synthesized compounds have accepted profiles of drug-likeness with low toxicity. Finally, an interesting SAR analysis was concluded to help the future design of more potent HDACIs in the future by medicinal chemists.

Abstract
The title mol-ecule, C20H15NO3, adopts a Z-shaped conformation with the carboxyl group nearly coplanar with the di-hydro-quinoline unit. In the crystal, corrugated layers are formed by C-H⋯O hydrogen bonds and are stacked by C-H⋯π(ring) inter-actions. Hirshfeld surface analysis indicates that the most important contributions to the crystal packing are from H⋯H (43.3%), H⋯C/C⋯H (26.6%) and H⋯O/O⋯H (16.3%) inter-actions. The optimized structure calculated using density functional theory at the B3LYP/ 6-311 G(d,p) level is compared with the experimentally determined structure in the solid state. The calculated HOMO-LUMO energy gap is 4.0319 eV.

Abstract
Quinoline is a versatile pharmacophore, a privileged scaffold and an outstanding fused heterocyclic compound with a wide range of pharmacological prospective such as anticancer, anti-inflammatory, antibacterial, antiviral drug and superlative moiety in drug discovery. The quinoline hybrids have already been shown excellent results with new targets with a different mode of actions as an inhibitor of cell proliferation by cell cycle arrest, apoptosis, angiogenesis, disruption of cell migration and modulation. This review emphasized the mode of action, structure activity relationship and molecular docking to reveal the various active pharmacophores of quinoline hybrids accountable for novel anticancer, anti-inflammatory, antibacterial and miscellaneous activities. Therefore, several quinoline candidates are under clinical trials for the treatment of certain diseases, for example ferroquine (antimalarial), dactolisib (antitumor) and pelitinib (EGFR TK inhibitors) etc. Plenty of research has been summarized the recent advances of quinoline derivatives and explore the various therapeutic prospects of this moiety. This review would help the researchers to strategically design diverse novel quinoline derivatives for the development of clinically viable drug candidates for the treatment of incurable diseases.

Abstract
A series of new chalcones containing fluoro atom at B ring have been designed, synthesized, and evaluated to be antiproliferative activity against a panel of human tumor cell lines. Some of the analogs (8, 9, 12, 45, 46 and 48) displayed powerful antiproliferative effects to certain human tumor cells, but all of them were devoid of any cytotoxicity towards the normal HEK 293. Acridine orange staining data supported that the cytotoxic and antiproliferative effects of the synthesized analogs on tumor cells are mediated through apoptosis. The compounds 12 and 46 manifested concentration-dependent antiproliferative activity in human hepatocellular carcinoma cell lines using an xCELLigence assay. The structures and antiproliferative activity relationship were further supported by in silico molecular docking study of the compounds against tubulin protein which suggests our compounds interference to cell division.

Abstract
A series of novel 2-oxoquinoline derivatives containing arylaminothiazole were designed and synthesized as potential antitumor agents. The synthesized compounds were evaluated for their in vitro cytotoxicity activity against HeLa, NCI-H460, T24 and SKOV3 cancer cell lines using MTT assay. Among them, compound A7 exhibited the most potent activity against the test cancer cell lines, with the IC50 values ranged from 4.4 to 8.7 µM. The results of tubulin polymerization assay showed that compound A7 could inhibit tubulin polymerization in vitro. Meanwhile, molecular docking study revealed that A7 can bind to the colchicine site of tubulin and formed hydrogen bonds with key amino acid residues in the active site. Further mechanism study demonstrated that compound A7 blocked cell cycle arrest at G2/M phase, induced cell apoptosis and depolarized mitochondria of HeLa cells. Collectively, our findings suggest that A7 could serve as a promising lead for the development of more efficient microtubule polymerization inhibitors for cancer therapy.

Abstract
A series of piperazinyl-1,2-dihydroquinoline carboxylates were synthesized by the reaction of ethyl 4-chloro-1-methyl-2-oxo-1,2-dihydroquinoline-3-carboxylates with various piperazines and their structures were confirmed by 1H NMR, 13C NMR, IR and mass spectral analysis. All the synthesized compounds were screened for their in vitro antimicrobial activities. Further, the in silico molecular docking studies of the active compounds was performed to explore the binding interactions between piperazinyl-1,2-dihydroquinoline carboxylate derivatives and the active site of the Staphylococcus aureus (CrtM) dehydrosqualene synthase (PDB ID: 2ZCQ). The docking studies revealed that the synthesized derivatives showed high binding energies and strong H-bond interactions with the dehydrosqualene synthase validating the observed antimicrobial activity data. Based on antimicrobial activity and docking studies, the compounds 9b and 10c were identified as promising antimicrobial lead molecules. This study might provide insights to identify new drug candidates that target the S. aureus virulence factor, dehydrosqualene synthase.

Abstract
RN1, a polysaccharide from flowers of Panax pseudo-ginsieng Wall. Var. notoginseng (Burkill) Hoo & Tseng, is a potential multi-targeting drug candidate for pancreatic cancer treatment. However, the active targeting domain of RN1 is still unknown. Herein, three RN1 derived branches were synthesized via [3+2] or [2+2] strategies, efficiently. Two pentasaccharides, 18 and 27, showed similar inhibition effect on pancreatic cancer BxPC-3 cells to that of RN1 at same concentration. Interestingly, tetrasaccharide 21 potently inhibited gemcitabineresistant cell line Panc-1 at high concentration. These suggest that the branches of RN1 might be the active targeting domain and tetrasaccharide 21 might be a potential leading compound for pancreatic cancer with gemcitabine resistance.

Eur J Med Chem 2017; 136:283-293. [PMID: 28505533 DOI: 10.1016/j.ejmech.2017.04.067] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2017] [Revised: 04/10/2017] [Accepted: 04/24/2017] [Indexed: 10/19/2022]
Abstract
Sphingomyelin synthase (SMS) is a membrane enzyme that catalyzes the synthesis of sphingomyelin, is required for the maintenance of plasma membrane microdomain fluidity, and has two isoforms: SMS1 and SMS2. Although these isoforms exhibit the same SMS activity, they are different enzymes with distinguishable subcellular localizations. It was reported that SMS2 KO mice displayed lower inflammatory responses and anti-atherosclerotic effects, suggesting that inhibition of SMS2 would be a potential therapeutic approach for controlling inflammatory responses and atherosclerosis. This study aimed to discover a novel small-molecule compound that selectively inhibits SMS2 enzymatic activity. We developed a human SMS2 enzyme assay with a high-throughput mass spectrometry-based screening system. We characterized the enzymatic properties of SMS2 and established a high-throughput screening-compatible assay condition. To identify human SMS2 inhibitors, we conducted compound screening using the enzyme assay. We identified a 2-quinolone derivative as a SMS2 selective inhibitor with an IC50 of 950 nM and >100-fold selectivity for SMS2 over SMS1. The 2-quinolone exhibited efficacy in a cell-based engagement assay. We demonstrated that a more potent derivative directly bound to SMS2-expressing membrane fractions in an affinity selection mass spectrometry assay. Mutational analyses revealed that the interaction of the inhibitor with SMS2 required the presence of the amino acids S227 and H229, which are located in the catalytic domain of SMS2. In conclusion, we discovered novel SMS2-selective inhibitors. 2-Quinolone SMS2 inhibitors are considered applicable for leading optimization studies. Further investigations using these SMS2 inhibitors would provide validation tools for SMS2-relevant pathways in vitro and in vivo.

A novel piperazine linked β-amino alcohols bearing a benzosuberone scaffolds as anti-proliferative agents. Bioorg Med Chem Lett 2017; 27:792-796. [PMID: 28117204 DOI: 10.1016/j.bmcl.2017.01.031] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2016] [Revised: 12/30/2016] [Accepted: 01/11/2017] [Indexed: 01/06/2023]
Abstract
A new series of 1-((9-chloro-2,3-dimethyl-6,7-dihydro-5H-benzo[7]annulen-8-yl)methoxy)-3-(4-phenylpiperzin-1-yl) propan-2-ols (6a-k) have been designed, synthesized and their structures were established by spectroscopic data (FT-IR, 1H NMR, 13C NMR, HRMS) and further confirmed by X-ray analysis. The newly synthesized compounds 6a-k were evaluated for their in vitro anti-proliferative activity against four cancer cell lines such as HeLa (cervical), MDA-MB-231 (breast), A549 (lung) and MIAPACA (pancreatic). Among the compounds tested, the compound 6e displayed most potent activity against four cancer cell lines with GI50 values ranging from 0.010 to 0.097μM. The structure and anti-proliferative activity relationship was further supported by in silico molecular docking study of the active compounds against Colchicine binding site of β-tubulin.
