for the synthesis of 3-methyl-5-phenylethynyl[1,2,4]triazine (4), 6-methyl-3-phenylethynyl[1,2,4]triazine (5), and 5-methyl-3-phenylethynyl[1,2,4]triazine (6a) as analogues of 2-methyl-6-(phenylethynyl)pyridine (2). The compounds were evaluated for antagonism of glutamate-mediated mobilization of internal calcium in an mGluR5 in vitro efficacy assay. The most potent of the three analogues was 6a. Twenty

A series of 3,3'-disubstituted5,5'-bi(1,2,4-triazine) derivatives was synthesized and screened against the erythrocytic stage of Plasmodium falciparum 3D7 line. The most potent dimer, 6k, with an IC50 (50% inhibitory concentration) of 0.008 μM, had high in vitro potency against P. falciparum lines resistant to chloroquine (W2, IC50 = 0.0047 ± 0.0011 μM) and artemisinin (MRA1240, IC50 = 0.0086 ± 0
