Reversal Agent and Linker Variants of Reversed Chloroquines: Activities against Plasmodium falciparum
摘要:
We have shown that "reversed chloroquine molecules" constructed from chloroquine-like and resistance "reversal-agent"-like cores can be powerful drugs against malaria (J. Med. Chem. 2006, 49, 5623-5625). Several reversed chloroquines are now presented that probe parameters governing the activities against chloroquine-resistant and chloroquine-sensitive malaria strains. The design is tolerant to linker and reversal agent changes, but it piperazinyl group adjacent to the quinoline, at least for the group Of Compounds studied here, may be detrimental.
This disclosure provides a new class of compounds referred to as “reversed chloroquines” (RCQs), which are highly effective against CQ
R
and CQ
S
malaria parasites. RCQs are hybrid molecules, which include an antimalarial quinoline analog (such as chloroquine) moiety and a CQ
R
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 CQ
R
or CQ
S
Plasmodium
sp. (such as
P. falciparum
).
