In this study thirteen 2-aminopyrimidine derivatives were synthesised and screened as potential antagonists of adenosine A(1) and A(2A) receptors in order to further investigate the structure activity relationships of this class of compounds. 4-(5-Methylfuran-2-yl)-6[3-(piperidine-1-carbonyl)phenyl] pyrimidin-2-amine (8m) was identified as a compound with high affinities for both receptors, with an A(2A)Ki value of 6.34 nM and an A(1)Ki value of 9.54 nM. The effect of selected compounds on the viability of cultured cells was assessed and preliminary results indicate low cytotoxicity. In vivo efficacy at A(2A) receptors was illustrated for compounds 8k and 8m since these compounds attenuated haloperidol-induced catalepsy in rats. A molecular docking study revealed that the interactions between the synthesised compounds and the adenosine A2A binding site most likely involve Phe168 and Asn253, interactions which are similar for structurally related adenosine A(2A) receptor antagonists.
