Aminoquinazolines as TRPV1 antagonists: Modulation of drug-like properties through the exploration of 2-position substitution
摘要:
A focused SAR exploration of the lead 4-aminoquinazoline TRPV1 antagonist 2 led to the discovery of compound 18. In rats, compound 18 is readily absorbed following oral dosing and demonstrates excellent in vivo potency and efficacy in an acute inflammatory pain model. (C) 2008 Elsevier Ltd. All rights reserved.
Substituted quinazolin-4-ylamine analogues are provided. Such compounds are ligands that may be used to modulate specific receptor activity in vivo or in vitro, and are particularly useful in the treatment of conditions associated with pathological receptor activation in humans, domesticated companion animals and livestock animals. Pharmaceutical compositions and methods for using them to treat such disorders are provided, as are methods for using such ligands for receptor localization studies.

Compositions and methods are provided for the treatment of pain. Compositions and methods are further provided for inhibiting the development of tolerance to addictive therapeutic agents (especially narcotic analgesics) in patients treated with such agents; for minimizing adverse effects (e.g., dependence) resulting from treatment with such addictive agents; and for enhancing pain relief resulting from narcotic analgesic administration. The compositions generally comprise a nontoxic VR1 antagonist, optionally in combination with an addictive therapeutic agent. Patients may be treated with a VR1 antagonist before, during or after administration of the addictive therapeutic agent to prevent, decrease the severity of, delay or treat tolerance and/or other adverse effects of the addictive agent in the patient.
