Antiplasmodial and leishmanicidal activities of 2-cyano-3-(4-phenylpiperazine-1-carboxamido) quinoxaline 1,4-dioxide derivatives.
Malaria and leishmaniasis are two of the World’s most important tropical
parasitic diseases. Thirteen new 2-cyano-3-(4-phenylpiperazine-1-carboxamido) quinoxaline
1,4-dioxide derivatives (CPCQs) were synthesized and evaluated for their in vitro
antimalarial and antileishmanial activity against erythrocytic forms of Plasmodium
falciparum and axenic forms of Leishmania infantum. Their toxicity against VERO cells
(normal monkey kidney cells) was also assessed. None of the tested compounds was
efficient against Plasmodium, but two of them showed good activity against Leishmania.
Toxicity on VERO was correlated with leishmanicidal properties

Gracikioethers E-J, new oxygenated polyketides from the marine sponge Plakinastrella mamillaris
Purification of the apolar extracts of the marine sponge Plakinastrella mamillaris afforded the isolation of
six new oxygenated polyketides, gracilioethers EeJ, featuring an unprecedented oxidation pattern of the
polycyclic core. On a common tricyclic core, gracilioethers E, G, and J feature the furanyliden methyl ester
substructure and gracilioethers F, H, and I display a g-lactone substructure. The new structures were
elucidated on the basis of extensive spectroscopic (1H and 13C NMR, COSY, HSQC, HMBC, and ROESY), MS,
computational and chemical methods. Pharmacological analysis demonstrated that gracilioether H is
endowed with in vitro antiplasmodial activity against a chloroquine resistant strain
