- SYNTHESIS, CHARACTERIZATION, CRYSTAL STRUCTURE, AND DFT STUDY OF N-(2-METHOXY-5- (4,4,5,5-TETRAMETHYL-1,3,2-DIOXABOROLAN-2-YL) PYRIDIN-3-YL)CYCLOPROPANESULFONAMIDE
-
Abstract: N-(2-methoxy-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-3-yl)cyclopropanesulfonamide is an organic intermediate with borate and sulfonamide groups, which can be synthesized through nucleophilic and amidation reactions. In this article, we characterize the structure of the title compound by 1H?and 13C NMR, IR, MS, and single crystal X-ray diffraction of the title compound for crystallographic and conformational analyses. The comparison of the actual value with the value calculated by density functional theory (DFT) shows that the crystal structures obtained by the two methods are consistent. On this basis, DFT is used to study the molecular electrostatic potential and frontier molecular orbitals of the title compound to further clarify certain physical and chemical properties of the compound.

- Discovery of Pyridopyrimidinones as Potent and Orally Active Dual Inhibitors of PI3K/mTOR
-
The identification and lead optimization of a series of pyridopyrimidinone derivatives are described as a novel class of efficacious dual PI3K/mTOR inhibitors, resulting in the discovery of 31. Compound 31 exhibited high enzyme activity against PI3K and mTOR, potent suppression of Akt and p70s6k phosphorylation in cell assays, and good pharmacokinetic profile. Furthermore, compound 31 demonstrated in vivo efficacy in a PC-3M tumor xenograft model.

- Discovery and Optimization of 2-Amino-4-methylquinazoline Derivatives as Highly Potent Phosphatidylinositol 3-Kinase Inhibitors for Cancer Treatment
-
Increased phosphatidylinositol 3-kinase (PI3K) signaling is among the most common alterations in cancer, spurring intensive efforts to develop new cancer therapeutics that target this pathway. In this work, we discovered a series of novel 2-amino-4-methylquinazoline derivatives through a hybridization and subsequent scaffold hopping approach that were highly potent class I PI3K inhibitors. Lead optimization resulted in several promising compounds (e.g., 19, 20, 37, and 43) with nanomolar PI3K potencies, prominent antiproliferative activities, favorable PK profiles, and robust in vivo antitumor efficacies. More interestingly, compared with 19 and 20, 37 and 43 demonstrated improved brain penetration and in vivo efficacy in an orthotopic glioblastoma xenograft model. Furthermore, preliminary safety assessments including hERG channel inhibition, AMES, CYP450 inhibition, and single-dose toxicity were performed to characterize their toxicological properties.

A series of [1,2,4]triazolo[1,5-a]pyridinylpyridines were synthesized and characterized. Their anti-proliferative activities in vitro were evaluated by MTT against three human cancer cell lines including HCT-116, U-87 MG and MCF-7 cell lines. The SAR of target compounds was preliminarily discussed. The compounds 1c and 2d with potent antiproliferative activities were tested for their effects on the AKT and p-AKT473. The anticancer effect of 1c was evaluated in mice bearing sarcoma S-180 model. The results suggest that the title compounds are potent anticancer agents.
