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.

A new set of 20 Series 4 Triazolopyrazine compounds were sent to have their efficacy evaluated against Plasmodium falciparum in-vitro at Dundee.

N.B. Potency values are an average of 2 runs. In certain cases (MMV897697, MMV897698, MMV897699, MMV897700, MMV897708, MMV897714), the 2 runs gave more-divergent-than-ideal values, however the averages are still reported.

The following results were obtained:

Brief comments:

Thioether, sulfoxide and sulfone were inactive again. The comparative ether compounds showed good to moderate activity.

Left hand cubane bioisosteres showed good to moderate activty. Right hand isosteres were inactive.

All ether-triazole linked compounds were inactive.

Both 3- and 4-OMe compounds were active

MMV897708 showed slightly reduced activity to the OCHF2 analogue (MMV672687). MMV897707 was inactive compared with the active OCHF2 analogue (MMV897763).

Compounds with a methylated benzylic position showed moderate activity.

MMV897706 and MMV897705 were inactive.
