Dysregulation of translation initiation factor 4E (eIF4E) activity occurs in various cancers. Mitogen-activated protein kinase (MAPK) interacting kinases 1 and 2 (MNK1 and MNK2) play a fundamental role in activation of eIF4E. Structure-activity relationship-driven expansion of a fragment hit led to discovery of dual MNK1 and MNK2 inhibitors based on a novel pyridine-benzamide scaffold. The compounds possess promising in vitro and in vivo pharmacokinetic profiles and show potent on target inhibition of eIF4E phosphorylation in cells.

Herein, The highly efficient and practical synthesis of 2,3-dihydroquinazolinones I [R1 = n-Pr, cyclohexyl, Ph, etc.; R2 = H, Me, allyl; R3 = H, Me; R4 = H, 6-Me, 7-Cl, etc.; X = O, S] directly from diverse aldehydes with excellent yields and enantioselectivity was reported. Particularly, this protocol afforded better enantiocontrol for aliphatic aldehydes (up to 99% yield, 97% ee), which always gave unsatisfactory results in the previous studies. Moreover, this catalytic system showed wide tolerance to different functional groups such as alkenyl, nitro and halogens. Most importantly, its practicability was well elucidated via the gram-scale synthesis of different types of products at 0.1 mol% catalyst loading and the simplified work-up procedure. To better understand the reaction pathway and origin of the enantioselectivity, DFT calculations were also performed.

B. published the artcile< Synthetic, structural, extraction and theoretical studies of uranyl nitrate dithio-diglycolamide compounds>, Safety of 2-Chloro-N,N-diisobutylacetamide, the main research area is crystal structure thioglycolamide thiotolylamide uranyl complex preparation actinide extraction; optimized mol structure glycolamide thioglycolamide uranyl monodentate bidentate extraction.

Dithio-diglycolamide ligands [(CH2SCH2CONR2)2] (R = iPr, Bu, iBu, C8H17) and [C7H6(SCH2CONR2)2] (R = iBu) were prepared and characterized. The complex chem. of these ligands with uranyl nitrate was studied using IR, NMR and ESI-MS techniques and elemental anal. The structures for two of the compounds, [UO2(NO3)2(CH2SCH2CONBu2)2] (2) and [UO2(NO3)2C7H6(SCH2CON{iBu}2)2] (4), were determined by the x-ray diffraction method and revealed a bidentate chelating mode of bonding for the ligands in the solid state. The structures further show that the uranyl group is surrounded by six O atoms in a hexagonal bi-pyramidal geometry. Theor. studies were carried out to explain the relative stability of this chelating mode of ligand bonding. Extraction studies of U(VI), Pu(IV) and Am(III) ions from HNO3 by one of the ligands, [(CH2SCH2CON{C8H17}2)2] (L4), in dodecane show appreciable extractions The extracted metal ions could be back extracted quant. using 0.5M HNO3 or a mixture of 0.5 M HNO3 and 0.5M H2C2O4.

In the past few years, there have been many advances in the efforts to cure patients with hepatitis C virus (HCV). The ultimate goal of these efforts is to develop a combination therapy consisting of only direct-antiviral agents (DAAs). In this paper, we discuss our efforts that led to the identification of a bicyclic template with potent activity against the NS5B polymerase, a critical enzyme on the life cycle of HCV. In continuation of our exploration to improve the stilbene series, the 3,5,6,8-tetrasubstituted quinoline core was identified as replacement of the stilbene moiety. 6-Methoxy-2-(1H)-pyridone was identified among several heterocyclic headgroups to have the best potency. Solubility of the template was improved by replacing a planar aryl linker with a saturated pyrrolidine. Profiling of the most promising compounds led to the identification of quinoline I (RG7109), which was selected for advancement to clin. development.
