  • Patent number: 9493420
    Abstract: This disclosure provides a new class of compounds referred to as “reversed chloroquines” (RCQs), which are highly effective against CQR and CQS malaria parasites. RCQs are hybrid molecules, which include an antimalarial quinoline analog (such as chloroquine) moiety and a CQR reversal moiety. Exemplary RCQ chemical structures are provided. Also provided are pharmaceutical compositions including the disclosed RCQ compounds, and methods of using such compounds and compositions for the treatment of malaria and inhibition of CQR or CQS Plasmodium sp. (such as P. falciparum).
    Type: Grant
    Filed: July 25, 2013
    Date of Patent: November 15, 2016
    Assignee: Portland State University
    Inventors: David H. Peyton, Steven Burgess
  • Patent number: 8658648
    Abstract: The disclosure provides modified chloroquine compounds having single ring or fused ring moieties. Also provided are pharmaceutical compositions comprising such compounds, methods of using such compounds to inhibit or treat diseases or conditions caused by chloroquine-resistant (CQR) and chloroquine-sensitive (CqS) malaria parasites and other CQ-susceptible microorganisms, and processes and intermediates useful for preparing such compounds.
