A set of 12 compounds were sent to Syngene for evaluation against blood stage asexual NF54 strain of Plasmodium falciparum.

Samples sent for in vitro efficacy evaluation against Plasmodium falciparum asexual blood stage

Data were received (via the ScienceCloud portal at MMV) on October 10th. Data for one compound was missing, and subsequently received on Oct 23rd. Data:

Syngene Data Oct 2014


1. CF3 tolerated as a replacement for CHF2 in northeast, which may make synthesis simpler. Impact of using Me looks to be to reduce potency.

Impact of CH3 vs CF3 vs CHF2

(Note - need analysis along similar lines for impact of Cl and CN)

2. High sensitivity to changes in northwest ring. Compare MMV675951 and MMV675950


3. Pyridyl is a bad substitution. Compare MMV675963 with MMV675961, MMV675962. Also compare MMV675949 with OSM-S-189.

4. Benzylic in northwest not bad, but deleterious compared to phenethyl (MMV639565, 38 nM).
