[EN] PYRROLIDINYL UREA, THIOUREA, GUANIDINE AND CYANOGUANIDINE COMPOUNDS AS TRKA KINASE INHIBITORS [FR] COMPOSÉS DE N-PYRROLIDINYLE URÉE, THIO-URÉE,GUANIDINE ET CYANOGUANIDINE EN TANT QU'INHIBITEURS DE LA KINASE TRKA
A mild, general and efficient hydrocyanation and hydroarylation of enamines catalyzed by Co(salen) complexes are described. Both reactions include regioselective C-H bond formation of enamines, and the corresponding products are obtained in high yield. Hydroarylation critically discriminates the benzyl and benzoyl aromatic rings on nitrogen in cyclization step, and the corresponding isoindolinones
Disclosed are novel compositions comprising a lipid and imexon or a derivative thereof. Also disclosed are liposomal compositions comprising imexon or a derivative thereof. Methods for administrating pharmaceutically acceptable compositions comprising a lipid and imexon or a derivative thereof for the treatment of diseases, such as cancer, are also disclosed herein.
The present invention is directed to novel anti-cancer compounds of the formula.
wherein
X is CN,
R4 is hydrogen or lower alkyl; and
R5 is lower alkyl, lower cycloalkyl, alkenyl, alkynyl, aryl, monosubstituted aryl, disubstituted aryl, aryl lower alkyl, lower alkoxycarbonyl lower alkyl, or heterocyclic ring, with the proviso that when X is CN, and R4 is hydrogen, then R5 is not CH3, C6H5, or, p-nitrophenyl.
R4, R5 and N taken together form a heterocyclic ring.
