生物&药学活性

HEP-50768 is a potent and selective small-molecule inverse agonist of MRGPRX4 (hX4) with IC50 of 14 nM.
HEP-50768 with the (S)-configuration demonstrates significantly greater inhibitory activity than its (R)-enantiomer.
HEP-50768 exhibits minimal cross-reactivity with other itch-associated MRGPRX family members, shows only weak inhibition of MRGPRX1 (hX1) with an IC50 of 16 μM and MRGPRX2 (hX2) with an IC50 of 1.5 μM.
HEP-50768 also does not activate either hX1 or hX2.
HEP-50768 (5 or 10 mg kg, oral) alleviates DCA-3S-induced pruritus in an hX4-humanized rat model.
