GPR39 Inhibitors

GPR39 Inhibitors primarily operate by blocking the signalling pathways that GPR39 is directly involved in. This can be achieved by inhibiting the Gq/11 proteins, as GPR39 signals through these proteins. Specific inhibitors for these proteins include YM-254890, FR 900359, and UBO-QIC. By inhibiting the Gq/11 proteins, these chemical compounds can lead to the functional inhibition of GPR39. In addition, the inhibition of downstream components of the Gq/11 proteins, such as PI3K and MEK, can also induce the functional inhibition of GPR39. This inhibition can be achieved with compounds like LY294002, Wortmannin, PD98059, and U0126.

In addition to the Gq/11 pathway, GPR39 can also signal through the G12/13 proteins. Therefore, the inhibition of these proteins and their downstream components can also result in the functional inhibition of GPR39. M119 is a specific G12/13 inhibitor, while Y-27632 is a ROCK inhibitor, a downstream component of the G12/13 proteins. Finally, GPR39 inhibitors also include compounds like ICI 182,780, GW 9662, and ZD 1839, which act by inhibiting the estrogen receptor, PPARγ, and EGFR, respectively.
