-
Page/Page column 75; 76, (2018/10/19)
This invention relates to certain novel pyrazine derivatives (Formula I) as SHP2 inhibitors which is shown as formula I, their synthesis and their use for treating a SHP2 mediated disorder. More particularly, this invention is directed to fused heterocyclic group derivatives useful as inhibitors of SHP2, methods for producing such compounds and methods for treating a SHP2-mediated disorder.
Heterodimeric bis(amino thiol) complexes of oxorhenium(V) that mimic the structure of steroid hormones. Synthesis and stereochemical issues

We have prepared a series of bis-bidentate complexes of rhenium that mimic the size, shape, and peripheral functionality of steroidal androgens. In a model system, we used 2D NMR and X-ray crystallographic analysis to show that adjacent N-methyl and oxo substitutents adopt an anti configuration during the coordination reaction. We have synthesized a bis-bidentate oxorhenium(V) complex whose structure and peripheral functionality mimic 5α-dihydrotestosterone. 2D-NMR analysis indicates that the N-methyl and oxo substituents are driven into the steroidal anti configuration (β-N-methyl, α-oxo) by the β-orientation of the methyl group equivalent to C-18. Thus, this metal complex provides a remarkable structural and stereochemical mimic of a steroid. Its in vivo stability, however, appears to be limited.

2-thienoimidazoles were synthesized and investigated as potential inhibitors of gastric H+/K+-ATPase.The isomers of the two possible thienoimidazole series were found to be potent inhibitors of gastric acid secretion in vitro and in vivo.Structure-activity relationships indicate that especially lipophilic alkoxy, benzyloxy, and phenoxy substituents with additional electron-demanding properties in the 4-position of the pyridine moiety combined with an unsubstituted thienoimidazole lead to highly active compounds with a favorable chemical stability.Various substitution patterns in the thienoimidazole moiety result in lower biological activity.The heptafluorobutyloxy derivative saviprazole (HOE 731, 5d) was selected for further development and is currently undergoing clinical evaluation.Comprehensive pharmacological studies indicate a pharmacodynamic profile different to omeprazole, the first H+/K+-ATPase blocker introduced on the market.
