Direct conversion of pyranose anomeric OH→F→R in the artemisinin family of antimalarial trioxanes

Abstract Eleven examples form the basis of a short and effective synthetic method for replacement of an anomeric fluorine atom by saturated, unsaturated, aryl and heteroaryl carbon nucleophiles to prepare α- or β-oriented C 10 -R derivatives of the trioxane 10-deoxoartemisinin.

4-(Heteroarylaminomethyl)-N-(2-aminophenyl)-benzamides and their analogs as a novel class of histone deacetylase inhibitors.

The synthesis and biological evaluation of a variety of 4-(heteroarylaminomethyl)-N-(2-aminophenyl)-benzamides and their analogs is described. Some of these compounds were shown to inhibit HDAC1 with IC(50) values below the micromolar range, induce hyperacetylation of histones, upregulate expression of the tumor suppressor p21(WAF1/Cip1), and inhibit proliferation of human cancer cells. In addition, certain compounds of this class were active in several human tumor xenograft models in vivo.
