Owing to their unique functions in regulating glucose, lipid and cholesterol metabolism, PPARs (peroxisome proliferator-activated receptors) have drawn special attention for developing drugs treat type-2 diabetes. By combining the benefit of PPAR-alpha agonists (such as fibrates) with glycemic advantages PPAR-gamma thiazolidinediones), dual PPAR approach can both improve metabolic effects minimize side caused by either agent alone, hence has become a promising strategy designing effective...
Inhibition of α-glucosidase and α-amylase decreases postprandial blood glucose levels delays absorption, making it a treatment strategy for type 2 diabetes. This study examined in vivo vitro antidiabetic activities natural prenylchalconaringenins 1 prenylnaringenins 3 4, found hops beer. 3′-Geranylchalconaringenin (2) competitively irreversibly inhibited (IC50 = 1.08 μM) with activity 50-fold higher than that acarbose 51.30 showed moderate inhibitory against 20.46 μM). Docking analysis...
The paper describes a convenient and facile methodology for the regioselective synthesis of fused oxazepinone scaffolds. This process is an efficient construction scaffold by one-pot coupling/Smiles rearrangement/cyclization approach. transition metal-free has potential applications in biologically medicinally relevant compounds.
Given the special role of insulin and leptin signaling in various biological responses, protein-tyrosine phosphatase-1B (PTP1B) was regarded as a novel therapeutic target for treating type 2 diabetes obesity. However, owing to highly conserved (sequence identity about 74%) active pocket, targeting PTP1B drug discovery is great challenge. In this study, we employed software package Discovery Studio develop 3D QSAR pharmacophore models TCPTP inhibitors. It further validated by three methods...
Cell division cycle 25B is a key cell regulator and widely considered as potent clinical drug target for cancers. This research focused on identifying potential compounds in theory which are able to disrupt transient interactions between CDC25B its CDK2/Cyclin A substrate.By using the method of ZDOCK RDOCK, most optimized 3D structure complex with was constructed validated two methods: 1) superimposition proteins; 2) analysis hydrogen bond distances Arg 488(N1)-Asp 206(OD1), 492(NE)-Asp...
Abstract Diabetic macular edema, also known as diabetic eye disease, is mainly caused by the overexpression of vascular endothelial protein tyrosine phosphatase (VE‐PTP) at hypoxia/ischemic. AKB‐9778 a VE‐PTP inhibitor that can effectively interact with active site to inhibit activity VE‐PTP. However, binding pattern and dynamic implications on system molecular level are poorly understood. Through docking, it was found docked well in pocket interactions hydrogen bond Van der Waals....
Ectopic overexpression of protein tyrosine phosphatase liver regeneration-1 (PTP4A1, also called PRL-1) markedly enhanced hepatocellular carcinoma (HCC) cells migration and invasion. The PTP4A1 trimerization played a vital role in mediating cell proliferation motility. Biochemical structural studies have proved that the compound 4AX, well-known inhibitor for PRL1, directly binds to trimer interface obstructs formation PTP4A1. However, molecular basis ligand-4AX inhibition on conformations...
The over-activation of Ras/mitogen-activated protein kinase (MAPK) signaling pathway associated with a variety cancers is usually related abnormal activation Src-homology 2 domain-containing tyrosine phosphatase (SHP2). For this purpose, SHP2 has attracted extensive interest as potential target for cancer treatment. RMC-4550, newly developed selective inhibitor SHP2, possesses an overwhelming advantage over the previous generation SHP099 in terms vitro activity. However, binding mode...
Abstract Four novel oxepin‐containing pyrimidines, namely oxepinamides D–G ( 1 – 4 ), were isolated from cultures of Aspergillus puniceus F02Z‐1744. The structures elucidated by analyzing their spectroscopic data generated 1D and 2D NMR MS methods. configurations 2 established based on single‐crystal X‐ray crystallographic analysis. All four compounds showed transcriptional activation Liver X Receptor α (LXRα) with EC 50 values 10.6, 12.8, 13.6, 12.1 μ M , respectively.
Noonan syndrome (NS) is a common autosomal dominant congenital disorder which could cause the cardiopathy and cancer predisposition. Previous studies reported that knock-in mouse models of mutant D61G SHP2 exhibited major features NS, demonstrated mutation NS. To explore effect on explain high activity mutant, molecular dynamic simulations were performed wild type (WT) mutated SHP2-D61G, respectively. The principal component analysis cross-correlation mapping, associated with secondary...
Alkylglycerone phosphate synthase (AGPS) is an oncogene and can be considered as antitumor drug target. The aim of the present study was to design novel nitrogenous heterocyclic compound improving targetability by computer-aided technology targeting AGPS. A total 12 compounds were designed predicted absorption, distribution, metabolism excretion parameters/toxicity. Their activity in terms proliferation inhibition, cell cycle arrest apoptosis induction then measured using MTS assay a...
PPARα and PPARγ have been the most widely studied Peroxisome proliferator-activated receptor (PPAR) subtypes due to their important roles in regulating glucose, lipids, cholesterol metabolism. By combining lowering serum triglyceride levels benefit of agonists (such as fibrates) with glycemic advantages TZD), dual PPAR approach can both improve metabolic effects minimize side caused by either agent alone, hence, has become a promising strategy for designing effective drugs against type-2...
SHP2 is a non-receptor protein tyrosine phosphatase (PTP) encoded by the PTPN11 gene involved in cell death pathway (PD-1/PD-L1) and growth differentiation (MAPK). Moreover, mutations have been implicated Leopard syndrome (LS), Noonan (NS), juvenile myelomonocytic leukemia (JMML) several types of cancer solid tumors. Thus, inhibitors are much needed reagents for evaluation as therapeutic target. A series novel ethyl 4-(phenoxymethyl)-2-phenylthiazole-5-carboxylate derivatives were designed...
Due to the vital role in many cell regulatory processes, such as cycle control, survival and apoptosis, well growth neurotransmitter signaling, Src homology 2 (SH2) domain-containing phosphatase 2(Shp2) has attracted considerable attention for developing drugs treat cancers. In this study, by means of powerful “core hopping” technique, a novel class inhibitors was discovered based on compound II-B08. It observed molecular dynamics simulations that these not only possessed same function...
