ML382 是一种有效选择性的 Mas 相关 G 蛋白偶联受体 X1 MRGPRX1 (MrgX1) 正向调节剂，EC₅₀ 为 190 nM。

ML382 is a potent and selective MRGPRX1 (Mas-related G protein-coupled receptor X1, MrgX1) positive allosteric modulator, with an EC 50 of 190 nM.

EC50: 190 nM (MRGPRX1)

In the absence of ML382, the IC50 for BAM8-22 inhibition of ICa is 0.66 ± 0.05 μM. In the presence of 0.1 μM, 1 μM, 10 μM, and 30 μM ML382, BAM8-22 IC50 is reduced to 0.43 ± 0.02 μM, 0.25 ± 0.02 μM, 0.06 ± 0.01 μM, and 0.08 ± 0.01 μM, respectively. A lower IC50 generally indicates a higher potency; thus, ML382 dose-dependently increases the potency of BAM8–22, further demonstrating that ML382 is a positive allosteric modulator of MRGPRX1. has not independently confirmed the accuracy of these methods. They are for reference only.

ML382 (5 μM) significantly increases inhibition of I Ca by a low concentration of BAM8–22 (0.5 μM) in DRG neurons from MrgprX1 mice. ML382 enhances the inhibition of spinal synaptic transmission by BAM8-22 in MrgprX1 mice. ML382 (25 μM, 125 μM, and 250 μM; 5 μL; i.th.;) dose-dependently attenuates heat hypersensitivity in MrgprX1 mice. ML382 (lumbar puncture injection; 25 μM, 5 μL) leads to a significant increase in postconditioning time spent in the ML382-paired chamber, compared with the preconditioning value. ML382 inhibits nerve injury-induced ongoing pain in MrgprX1 mice. has not independently confirmed the accuracy of these methods. They are for reference only.
