Antimalarial activity of phenazines from lapachol, β-lapachone and its derivatives against Plasmodium falciparum in vitro and Plasmodium berghei in vivo

TL;DR: These simple phenazines, containing polar (-Br,-I) and ionizable (-SO(3)H, -OH) groups, easily synthesized from cheap, natural or synthetic precursors (lapachol and beta-lapachone), at rather low cost, provide prototypes for development of new antimalarials aiming the chloroquine resistant parasites.
Journal ArticleDOI

Antiplasmodial triterpene from Vernonia brasiliana.

TL;DR: The hexane extract from leaves of Vernonia brasiliana (L.) Druce (Compositae) was active in vitro against Plasmodium falciparum and in vivo in mice infected with Plas modium berghei, and lupeol was identified as a compound responsible for the activity, inhibiting the P.falcipareum growth by 45% when tested at 25 micrograms/ml.

An E-model implementation for speech quality evaluation in VoIP systems

TL;DR: A voice quality measurement tool based on the ITU-T E-model is presented and some errors found in these documents are pointed.
