Abstract
Malaria remains one of the deadliest diseases in the world today. Novel chemoprophylactic and chemotherapeutic antimalarials are needed to support the renewed eradication agenda. We have discovered a novel antimalarial acridone chemotype with dual-stage activity against both liver-stage and blood-stage malaria. Several lead compounds generated from structural optimization of a large library of novel acridones exhibit efficacy in the following systems: (1) picomolar inhibition of in vitro Plasmodium falciparum blood-stage growth against multidrug-resistant parasites; (2) curative efficacy after oral administration in an erythrocytic Plasmodium yoelii murine malaria model; (3) prevention of in vitro Plasmodium berghei sporozoite-induced development in human hepatocytes; and (4) protection of in vivo P. berghei sporozoite-induced infection in mice. This study offers the first account of liver-stage antimalarial activity in an acridone chemotype. Details of the design, chemistry, structure-activity relationships, safety, metabolic/pharmacokinetic studies, and mechanistic investigation are presented herein.

Abstract
This paper reviews the photoinduced reactions of benzodioxinones and how they function in polymer synthesis and UV curing applications. The mechanistic characteristics of the ketene and benzophenone production from the photolysis of benzodioxinone indicate that, under certain conditions, each intermediate may undergo further reactions expedient for the formation of various polymeric structures. While ketenes are efficient contributors to step-growth polymerization when subjected to reaction with the compounds possessing hydroxyl or amine groups, the released benzophenone can be utilized as a photoinitiator in both the free radical and cationic polymerizations. It has been shown that the photolysis of heterobifunctional monomers equipped with benzodioxinone and aliphatic hydroxyl groups leads to the formation of oligoesters with a narrow molecular weight distribution. We also validated the photochemical ability of benzodioxinone to induce the synthesis of block and graft copolymers, hybrid and branched polymers, and cross-linked monofunctional vinyl monomers or hydroxyl group-containing linear polymers.
