Novel in vivo active anti-malarials based on a hydroxy-ethyl-amine scaffold
摘要:
A novel series of anti-malarials, based on a hydroxy-ethyl-amine scaffold, initially identified as peptidomimetic protease inhibitors is described. Combination of the hydroxy-ethyl-amine anti-malarial phramacophore with the known Mannich base pharmacophore of amodiaquine (57) resulted in promising in vivo active novel derivatives.

The selective electrohydrogenation of nitro aliphatic and nitro aromatic functional groups in molecules containing other groups that are easy to hydrogenate (activated double bond, carbon-iodine bond, nitrile,) has been sucessfully carried out in slightly acidic (pH = 3) or neutral (pH = 5-6) methanol-water solutions at Devarda copper and Raney cobalt electrodes. The electrochemical synthesis of a quinolone 15 and a quinoxaline 18 is also reported. Preliminary results on the preparative electroreduction of 5-nitroindole 21 on Hg in aqueous methanol with HBr as supporting electrolyte are presented and dicussed for the first time.

The optimization campaign for a nitrofuran antitubercular hit (N-benzyl-5-nitrofuran-2-carboxamide; JSF-3449) led to the design, synthesis, and biological profiling of a family of analogs. These compounds exhibited potent in vitro antitubercular activity (MIC = 0.019-0.20 μM) against the Mycobacterium tuberculosis H37Rv strain and low in vitro cytotoxicity (CC50 = 40->120 μM) towards Vero cells.

A simple and efficient process has been developed for the direct conversion of benzamides and thiobenzamides into tertiarycarbinamines. A synthesis of benzonitriles from simple benzamides and a thiobenzamide is also described.

-Butoxy-Radical-Promoted α-Arylation of Alkylamines with Aryl Halides
作者:Ryota Ueno、Yuko Ikeda、Eiji Shirakawa
DOI:10.1002/ejoc.201700548
日期:2017.8.2
In the presence of a tert-butoxy radical precursor, the reaction of alkylamines with aryl halides was found to give alpha-arylated alkylamines through homolytic aromaticsubstitution of the halogen atoms.
