Discovery of GSK2126458, a highly potent inhibitor of PI3K and the mammalian target of rapamycin

Phosphoinositide 3-kinase alpha (PI3Kalpha) is a critical regulator of cell growth and transformation, and its signaling pathway is the most commonly mutated pathway in human cancers. The mammalian target of rapamycin (mTOR), a class IV PI3K protein kinase, is also a central regulator of cell growth, and mTOR inhibitors are believed to augment the antiproliferative efficacy of PI3K/AKT pathway inhibition. 2,4-Difluoro-N-{2-(methyloxy)-5-[4-(4-pyridazinyl)- 6-quinolinyl]-3-pyridinyl}benzenesulfonamide (GSK2126458, 1) has been identified as a highly potent, orally bioavailable inhibitor of PI3Kalpha and mTOR with in vivo activity in both pharmacodynamic and tumor growth efficacy models. Compound 1 is currently being evaluated in human clinical trials for the treatment of cancer.

Identification, synthesis, and pharmacological evaluation of tetrahydroindazole based ligands as novel antituberculosis agents

The resurgence of tuberculosis (TB), the incidence of drug-resistant strains of Mycobacterium tuberculosis (MTB), and the coinfection between TB and HIV have led to serious infections, high mortality, and a global health threat, resulting in the urgent search for new classes of antimycobacterial agents. Herein, we report the identification of a novel class of tetrahydroindazole based compounds as potent and unique inhibitors of MTB. Compounds 6a, 6m, and 6q exhibited activity in the low micromolar range against replicating Mycobacterium tuberculosis (R-TB) phenotype, with minimum inhibitory concentrations (MICs) of 1.7, 1.9, and 1.9 muM, respectively, while showing no toxicity to Vero Ccells. Moreover, studies aimed to assess the in vitro metabolic stability of 6a and 6m in mouse liver microsomes and in vivo pharmacokinetic profiles in plasma levels gave satisfactory results. This research suggests that tetrahydroindazole based anti-TB compounds can serve as a promising lead scaffold in developing new drugs to combat tuberculosis infections.

Discovery of potent and selective BRD4 inhibitors capable of blocking TLR3-induced acute airway inflammation

A series of diverse small molecules have been designed and synthesized through structure-based drug design by taking advantage of fragment merging and elaboration approaches. Compounds ZL0420 (28) and ZL0454 (35) were identified as potent and selective BRD4 inhibitors with nanomolar binding affinities to bromodomains (BDs) of BRD4. Both of them can be well docked into the acetyl-lysine (KAc) binding pocket of BRD4, forming key interactions including the critical hydrogen bonds with Asn140 directly and Tyr97 indirectly via a H2O molecule. Both compounds 28 and 35 exhibited submicromolar potency of inhibiting the TLR3-dependent innate immune gene program, including ISG54, ISG56, IL-8, and Grobeta genes in cultured human small airway epithelial cells (hSAECs). More importantly, they also demonstrated potent efficacy reducing airway inflammation in a mouse model with low toxicity, indicating a proof of concept that BRD4 inhibitors may offer the therapeutic potential to block the viral-induced airway inflammation.

Synthesis and biological evaluation of some bicyclic [2-(2,4-dimethylphenylthio)phenyl] aniline and its amide derivatives as potential antitubercular agents

Abstract: In the present investigation, a series of bicyclic [2-(2,4-dimethylphenylthio)phenyl] aniline analogues were synthesized and characterized by IR, NMR (1H and 13C) and mass spectra. All newly synthesized 15 compounds were inspected for their in vitro antitubercular activity against Mycobacterium tuberculosis (MTB) H 37Ra in both active and dormant state using an established XTT Reduction Menadione assay (XRMA). The titled compounds exhibited minimum inhibitory concentration (MIC90) ranging from 0.05 to >30 (mu g/mL). The potent four compounds were further evaluated in THP-1 infection model where they demonstrated significant antitubercular activity. All the ex vivo active were further evaluated for cytotoxic activity against THP-1, MCK-7 and HeLa cell lines in order to check selectivity index. All compounds were further screened against four different bacteria to assess their selectivity towards MTB. These derivatives could be considered as a precursor structure for further design of antituberculosis agent. Graphical Abstract: SYNOPSIS A series of bicyclic [2-(2,4-dimethylphenylthio)phenyl] aniline analogues were synthesized. All newly synthesized 15 compounds were inspected for their in vitro antitubercular activity against Mycobacterium tuberculosis (MTB) H 37Ra in both active and dormant state using an established XTT Reduction Menadione assay (XRMA).[Figure not available: see fulltext.].
