Biological Evaluation of Compounds

 

A set of 16 Series 4 Triazolopyrazine Frontrunner compounds were sent to have their efficacy re-evaluated against Plasmodium falciparum in-vitro at Dundee.

N.B. Potency values are an average of 2 runs. In one case (MMV672687), the 2 runs gave more-divergent-than-ideal values, however the average is still reported.

Discussion of the Frontrunner compounds and previous in-vitro data can be found here.

The following results were obtained:

Brief comments:

In comparison with the previous Frontrunner data linked above, all but one of the new potency values were slightly higher than before, but all values still indicate the active compounds were active etc.

MMV672687 had better activity than before even considering the N.B. above.
