Design, synthesis and biological evaluation of novel tetrahydrothieno [2,3-c]pyridine substitued benzoyl thiourea derivatives as PAK1 inhibitors in triple negative breast cancer.

ABSTRACT: The overexpression of P21-activated kinase 1 (PAK1) is associated with poor prognosis in several cancers, which has emerged as a promising drug targets. Based on high-throughput virtual screening strategy, tetrahydrothieno [2,3-c]pyridine scaffold was identified as an initial lead for targeting PAK1. Herein we reported our structure-based optimisation strategy to discover a potent PAK1 inhibitor (7j) which displayed potent PAK1 inhibition and antiproliferatory activity in MDA-MB-231 cells. 7j induced obviously G2/M cell cycle arrest via PAK1-cdc25c-cdc2 pathway, and also inhibited MAPK-ERK and MAPK-JNK cascade to induce MDA-MB-231 cell death. Together, these results provided a novel chemical scaffold as PAK1 inhibitor for breast cancer treatment.

Synthesis and biological evaluation of 2-amino-3-(3',4',5'-trimethoxybenzoyl)-6-substituted-4,5,6,7-tetrahydrothieno[2,3-c]pyridine derivatives as antimitotic agents and inhibitors of tubulin polymerization.

Project description:Microtubules are among the most successful targets of compounds potentially useful for cancer therapy. A new series of inhibitors of tubulin polymerization based on the 2-amino-3-(3,4,5-trimethoxybenzoyl)-4,5,6,7-tetrahydrothieno[b]pyridine molecular skeleton was synthesized and evaluated for antiproliferative activity, inhibition of tubulin polymerization, and cell cycle effects. The most promising compound in this series was 2-amino-3-(3,4,5-trimethoxybenzoyl)-6-methoxycarbonyl-4,5,6,7-tetrahydrothieno[b]pyridine, which inhibits cancer cell growth with IC(50)-values ranging from 25 to 90 nM against a panel of four cancer cell lines, and interacts strongly with tubulin by binding to the colchicine site. In this series of N(6)-carbamate derivatives, any further increase in the length and in the size of the alkyl chain resulted in reduced activity.

Synthesis and Biological Evaluation of New Antitubulin Agents Containing 2-(3',4',5'-trimethoxyanilino)-3,6-disubstituted-4,5,6,7-tetrahydrothieno[2,3-c]pyridine Scaffold.

Project description:Two novel series of compounds based on the 4,5,6,7-tetrahydrothieno[2,3-c]pyridine and 4,5,6,7-tetrahydrobenzo[b]thiophene molecular skeleton, characterized by the presence of a 3',4',5'-trimethoxyanilino moiety and a cyano or an alkoxycarbonyl group at its 2- or 3-position, respectively, were designed, synthesized, and evaluated for antiproliferative activity on a panel of cancer cell lines and for selected highly active compounds, inhibition of tubulin polymerization, and cell cycle effects. We have identified the 2-(3',4',5'-trimethoxyanilino)-3-cyano-6-methoxycarbonyl-4,5,6,7-tetrahydrothieno[2,3-c]pyridine derivative 3a and its 6-ethoxycarbonyl homologue 3b as new antiproliferative agents that inhibit cancer cell growth with IC50 values ranging from 1.1 to 4.7 ?M against a panel of three cancer cell lines. Their interaction with tubulin at micromolar levels leads to the accumulation of cells in the G2/M phase of the cell cycle and to an apoptotic cell death. The cell apoptosis study found that compounds 3a and 3b were very effective in the induction of apoptosis in a dose-dependent manner. These two derivatives did not induce cell death in normal human peripheral blood mononuclear cells, suggesting that they may be selective against cancer cells. Molecular docking studies confirmed that the inhibitory activity of these molecules on tubulin polymerization derived from binding to the colchicine site.

Computational Study of Bis-(1-(Benzoyl)-3-Methyl Thiourea) Platinum (II) Complex Derivatives as Anticancer Candidates.

Project description:BackgroundThe increasing incidence of cancer every year has resulted in cancer becoming one of the most common causes of death in the world. The most common types of cancer are breast cancer, lung cancer and prostate cancer. Thiourea is one of the compounds that have anticancer effects, and its activity can be increased by structural modifications, one of which involves making a Bis-(1-(benzoyl)-3-methyl thiourea) platinum (II) metal complex.PurposeThis study aims to obtain platinum (II)-thiourea complex compounds that have a more stable interaction as an anticancer agent compared to cisplatin.MethodsThe methods used are computational studies with molecular docking, simulation of molecular dynamics, and prediction of pharmacokinetics and toxicity.ResultsBased on the molecular docking of the platinum (II)-thiourea complex which has the most stable interaction with lower binding energy than the native ligand and the cisplatin, namely Bis-(3-methyl-1-(naphthalene-2-carbonyl)thiourea)) Platinum (II) against breast cancer receptors (3ERT) and lung cancer (2ITO) and compounds Bis-(1-(3-chlorobenzoyl)-3-methylthiourea) Platinum (II) against prostate cancer receptors (1Z95). The evaluation results of the stability of the interaction using a 50 ns molecular dynamic simulation showed that the Bis-(1-benzoyl-3-methylthiourea) Platinum (II) which binds to the prostate cancer receptor (1Z95) has the most stable interaction. Pharmacokinetic prediction results show that the platinum (II)-thiourea complex has a good pharmacokinetic profile, but there are several compounds that are mutagenic and hepatotoxic.ConclusionThe Bis-(1-(3,4-dichlorobenzoyl)-3-methyl thiourea) platinum (II) compounds could be a suitable anticancer agent for the lungs.

Synthesis, docking study and biological evaluation of some new thiourea derivatives bearing benzenesulfonamide moiety.

Project description:BACKGROUND:A series of novel N-(2, 6-dimethoxypyrimidin-4-yl)-4-(3-(aryl)thioureido) benzenesulfonamides 3a-t was synthesized by the addition of N-(2,6-dimethoxypyrimidin-4-yl)-4-isothiocyanatobenzenesulfonamide 2 to the appropriate aromatic amine. The structures of the synthesized compounds were inspired from the second line antituberculosis pro-drugs. RESULTS:Most of the new compounds were screened for their activity against Mycobacterium tuberculosis. The results of the antimycobacterial assay showed that compound 3i exerted the highest activity (MIC = 3.13 µg/mL), followed by compound 3s (MIC = 6.25 µg/mL). CONCLUSION:The structure-activity relationship (SAR) analysis revealed that the introduction of the benzo[1,3]dioxol moiety in 3i and the 4-morpholinyl-4-phenyl moiety in 3s has proven to give the most potent compounds in this study. Docking of the promising compounds inside the active site of M. tuberculosis enoyl reductase InhA was performed in order to emphasize the results. The compounds showed a similar orientation to that of GSK 625 inside the active site of 5JFO and bind to Met 98 in a way similar to that of the co-crystallized ligand.

2,3-Dichloro-pyridine.

Project description:The complete mol-ecule of the title compound, C(5)H(3)Cl(2)N, is generated by crystallographic twofold symmetry, which forces the pyridine N atom and the opposite C-H group to be statistically disordered. In the crystal, weak aromatic π-π stacking [centroid-centroid separation = 3.805 (4) Å and slippage = 1.704 Å] leads to [100] stacks of mol-ecules. Short Cl⋯Cl contacts [3.334 (3) Å] are also observed.

Design, synthesis and biological evaluation of 1<i>H</i>-pyrrolo[2,3-<i>b</i>]pyridine derivatives as potent fibroblast growth factor receptor inhibitors.

Project description:Abnormal activation of FGFR signaling pathway plays an essential role in various types of tumors. Therefore, targeting FGFRs represents an attractive strategy for cancer therapy. Herein, we report a series of 1H-pyrrolo[2,3-b]pyridine derivatives with potent activities against FGFR1, 2, and 3. Among them, compound 4h exhibited potent FGFR inhibitory activity (FGFR1-4 IC50 values of 7, 9, 25 and 712 nM, respectively). In vitro, 4h inhibited breast cancer 4T1 cell proliferation and induced its apoptosis. In addition, 4h also significantly inhibited the migration and invasion of 4T1 cells. Furthermore, 4h with low molecular weight would be an appealing lead compound which was beneficial to the subsequent optimization. In general, this research has been developing a class of 1H-pyrrolo[2,3-b]pyridine derivatives targeting FGFR with development prospects.
