Evaluation of Aminohydantoins as a Novel Class of Antimalarial Agents
摘要:
Given the threat of drug resistance, there is an acute need for new classes of antimalarial agents that act via a unique mechanism of action relative to currently used drugs. We have identified a set of druglike compounds within the Tres Cantos Anti-Malarial Set (TCAMS) which likely act via inhibition of a Plasmodium aspartic protease. Structure-activity relationship analysis and optimization of these aminohydantoins demonstrate that these compounds are potent nanomolar inhibitors of the Plasmodium aspartic proteases PM-II and PM-IV and likely one or more other Plasmodium aspartic proteases. Incorporation of a bulky group, such as a cyclohexyl group, on the aminohydantion N-3 position gives enhanced antimalarial potency while reducing inhibition of human aspartic proteases such as BACE. We have identified compound 8p (CWHM-117) as a promising lead for optimization as an antimalarial drug with a low molecular weight, modest lipophilicity, oral bioavailability, and in vivo antimalarial activity in mice.

The present invention relates to [1-(benzyl)-piperidin-4-yl]-([1,3,4]thiadiazol-2-yl)-amine and [1-(benzyl)-piperidin-4-yl]-(thiazol-2-yl)-amine derivatives of formula (I) that are fast dissociating dopamine 2 receptor antagonists, processes for preparing these compounds, pharmaceutical compositions comprising these compounds as an active ingredient. The compounds find utility as medicines for treating or preventing central nervous system disorders, for example schizophrenia, by exerting an antipsychotic effect without motor side effects.

[FR] Cette invention concerne des dérivés de [1- (benzyl) -pipéridin-4-yl] -( [1, 3,4] thiadiazol-2-yl) - amine et de [1- (benzyl) -pipéridine-4-yl] - (thiazol-2-yl) -amine, représentés par la formule (I), qui sont des antagonistes du récepteur 2 de la dopamine à dissociation rapide, des procédés de préparation de ces composés et des compositions pharmaceutiques contenant ces composés comme principe actif. Ces composés conviennent pour le traitement ou la prévention des troubles du système nerveux central, notamment de la schizophrénie, par l'action anti-psychotique qu'ils exercent sans effets secondaires moteurs.
