Flexible diaminodihydrotriazine inhibitors of Plasmodium falciparum dihydrofolate reductase: Binding strengths, modes of binding and their antimalarial activities
and shown to inhibit P. falciparum dihydrofolatereductase (PfDHFR) of the wild type or those carrying either single (S108N), double (C59R + S108N and A16V + S108T), triple (N51I + C59R + S108N and C59R + S108N + I164L) or quadruple (N51I + C59R + S108N + I164L) mutations, responsible for antifolate resistance. The flexibility of the side chain at position N1 has been included in the design so as to avoid
The invention provides novel deazaxanthine and deazahypoxanthine compounds. The compounds may be useful in the therapy of diseases and conditions in which dipeptidylpeptidase-IV (DPP-IV) is implicated.

This imaging method of AMPA receptors in the brain of primate organisms involves a step in which a substance which is administered to the primate organism and which selectively bonds to AMPA receptors in the brain of the primate organism and has a radiolabel is transported into the brain and made to bond with AMPA receptors in the brain, and, by detecting radiation emitted from the substance bonded to the AMPA receptors in the brain, data is obtained relating to the distribution and/or expression level of the AMPA receptors in the brain.
