The biased signaling modulation of non-GPCR receptors has yet to be exploited. Toll-like receptor 4 (TLR4) is one such non-GPCR receptor, which involves MyD88-dependent and TRIF-dependent dysregulation of TLR4 contributes to numerous diseases, which highlights the importance of biased modulator development The discovery of biased modulators of TLR4 would provide insight for the future development of biased modulators for other non-GPCR receptors.
