Amino Terminal Copper and Nickel Binding Motif Derivatives of Ovispirin-3 Display Increased Antimicrobial Activity via Lipid Oxidation

10.1021/acs.jmedchem.7b01117

2017-12-07

Antimicrobial peptides are short peptides secreted by the innate immune system to protect the host from pathogens. We have investigated the influence of the amino terminal copper and nickel binding (ATCUN) motif on derivatives of ovispirin-3 (OV-3), an α-heli...

Allosteric Inhibitors of SHP2 with Therapeutic Potential for Cancer Treatment

10.1021/acs.jmedchem.7b01520

2017-12-07

SHP2, a cytoplasmic protein-tyrosine phosphatase encoded by the PTPN11 gene, is involved in multiple cell signaling processes including Ras/MAPK and Hippo/YAP pathways. SHP2 has been shown to contribute to the progression of a number of cancer types including...

Novel Antitubercular 6-Dialkylaminopyrimidine Carboxamides from Phenotypic Whole-Cell High Throughput Screening of a SoftFocus Library: Structure–Activity Relationship and Target Identification Studies

10.1021/acs.jmedchem.7b01347

2017-12-07

A BioFocus DPI SoftFocus library of ∼35 000 compounds was screened against Mycobacterium tuberculosis (Mtb) in order to identify novel hits with antitubercular activity. The hits were evaluated in biology triage assays to exclude compounds suggested to functi...

Discovery of an Orally Bioavailable Benzofuran Analogue That Serves as a β-Amyloid Aggregation Inhibitor for the Potential Treatment of Alzheimer’s Disease

10.1021/acs.jmedchem.7b00844

2017-12-06

We developed an orally active and blood–brain-barrier-permeable benzofuran analogue (8, MDR-1339) with potent antiaggregation activity. Compound 8 restored cellular viability from Aβ-induced cytotoxicity but also improved the learning and memory function of A...

Augmentation of Anticancer Drug Efficacy in Murine Hepatocellular Carcinoma Cells by a Peripherally Acting Competitive N-Methyl-d-aspartate (NMDA) Receptor Antagonist

10.1021/acs.jmedchem.7b01624

2017-12-05

The most common solid tumors show intrinsic multidrug resistance (MDR) or inevitably acquire such when treated with anticancer drugs. In this work, we describe the discovery of a peripherally restricted, potent, competitive NMDA receptor antagonist 1l by a st...

Azetidine and Piperidine Carbamates as Efficient, Covalent Inhibitors of Monoacylglycerol Lipase

10.1021/acs.jmedchem.7b01531

2017-12-05

Monoacylglycerol lipase (MAGL) is the main enzyme responsible for degradation of the endocannabinoid 2-arachidonoylglycerol (2-AG) in the CNS. MAGL catalyzes the conversion of 2-AG to arachidonic acid (AA), a precursor to the proinflammatory eicosannoids such...

Design of Novel 3-Pyrimidinylazaindole CDK2/9 Inhibitors with Potent In Vitro and In Vivo Antitumor Efficacy in a Triple-Negative Breast Cancer Model

10.1021/acs.jmedchem.7b00663

2017-12-05

In the present study, a novel series of 3-pyrimidinylazaindoles were designed and synthesized using a bioinformatics strategy as cyclin-dependent kinases CDK2 and CDK9 inhibitors, which play critical roles in the cell cycle control and regulation of cell tran...

Design, Synthesis, and Biological Assessment of Biased Allosteric Modulation of the Urotensin II Receptor Using Achiral 1,3,4-Benzotriazepin-2-one Turn Mimics

10.1021/acs.jmedchem.7b01525

2017-12-05

Benzotriazepin-2-ones were designed to mimic the suggested bioactive γ-turn conformation of the Bip-Lys-Tyr tripeptide in Urocontrin ([Bip4]URP), which modulates the urotensin II receptor (UT) and differentiates the effects of the endogenous ligands urotensin...

Novel Molecules To Treat Chronic Central Nervous System Toxoplasmosis

10.1021/acs.jmedchem.7b01663

2017-12-04

A major challenge in treating toxoplasmosis in immunocompromised patients is lack of therapeutic agents to clear chronic infection and stop the recrudescence of infection after therapy. CDKP1 has emerged as a novel target for treating chronic infections and e...
