(EN) A new class of xanthine compounds, variously substituted at the 1, 3, 7 and 8 positions, is characterized by an ability to modulate the activity of key enzymes involved in drug metabolism. These compounds generally are useful in affecting drug metabolism and, particularly, in extending the circulating half-life of compounds that are metabolized via P-450-mediated pathways.(FR) La présente invention concerne une nouvelle classe de composés de la xanthine, diversement substitués en position 1, 3, 7 et 8, et caractérisés en ce qu'ils sont capables de moduler l'activité d'enzymes clés impliqués dans le métabolisme des médicaments. En général, ces composés sont utilisés pour modifier le métabolisme des médicaments et, en particulier, pour étendre la demi-vie circulante de composés qui sont métabolisés via les voies à médiation P-450.
