Arylboronic acids as dual-action FAAH and TRPV1 ligands

A series of 31 arylboronic acids designed on the basis of the pharmacophore model for a variety of TRPV1 antagonists was prepared and tested on FAAH and TRPV1 channel. Four of them, that is, compounds 3c, 4a, 5a,b acted as dual FAAH/TRPV1 blockers with IC50 values between 0.56 and 8.11 μM whereas ten others (compounds 1c,f–i, 2c–f, 4b) inhibited FAAH and activated/desensitized TRPV1.
