Patent number: 9216983Abstract: Compounds according to Formula I, Formula II, Formula III, Formula V, Formula VI, or to Formula VII, and pharmaceutical compositions of compounds that conform to Formula IV or Formula VIII: where R1 through R33 are prescribed, selectively inhibit P. falciparum dihydroorotate dehydrogenase. Accordingly, a method for preventing and treating malaria attaches to such compounds, as well as to pharmaceutically acceptable salts, solvates, stereoisomers, tautomers, and prodrugs thereof.Type: GrantFiled: December 19, 2008Date of Patent: December 22, 2015Assignees: BOARD OF REGENTS, UNIVERSITY OF TEXAS SYSTEM, UNIVERSITY OF WASHINGTON, MONASH UNIVERSITYInventors: Margaret Phillips, Pradipsinh K.

Patent number: 8530491Abstract: The present invention relates to novel compounds that are inhibitors of wild type and mutant dihydrofolate reductase (DHFR) of Plasmodium falciparum, which are useful for the treatment of malaria. It also relates to processes of making and using such compounds. The antimalarial compounds of the present invention have low toxicity to a host infected with the malarial parasite, and are potent when administered in pharmaceutical compositions.Type: GrantFiled: October 8, 2008Date of Patent: September 10, 2013Assignee: Medicines for Malaria Venture (MMV)Inventors: Yongyuth Yuthavong, Tirayut Vilaivan, Sumalee Kamchonwongpaisan, Bongkoch Tarnchompoo, Chawanee Thongpanchang, Penchit Chitnumsub, Jirundon Yuvaniyama, David Matthews, William Charman, Susan Charman, Livia Vivas, Sanjay Babu Katiyar

Patent number: 8067620Abstract: A means and method for treating malaria, schistosomiasis, and cancer using a spiro or dispiro 1,2,4-trioxolane is described. The preferred 1,2,4-trioxolanes include a spiroadamantane group on one side of the trioxolane group, and a spirocyclohexyl on the other side of the trioxolane group. In comparison to artemisinin semisynthetic derivatives, the compounds of this invention are structurally simple, easy to synthesize, non-toxic, and potent against malarial parasites. The compounds of the invention unexpectedly provide a single-dose cure for malaria, as well as prophylactic activity against the same. The compounds are also active against schistosomiasis and cancer.Type: GrantFiled: October 31, 2007Date of Patent: November 29, 2011Assignee: Medicines for Malaria Venture MMVInventors: Jonathan L. Vennerstrom, Yuxiang Dong, Susan A. Charman, Sergio Wittlin, Jacques Chollet, Darren J. Creek, Xiaofang Wang, Kamaraj Spiraghavan, Lin Zhou, Hugues Matile, William N. Charman
