An alternative and promising approach is allosteric modulation. Over the past decade, there has been a notable growth in the discovery of allosteric modulators for GPCRs Allosteric modulators that do not exhibit agonistic properties remain inactive in the absence of endogenous In this context, allosteric modulators exhibiting constrained positive or negative cooperativity are modulators with a diminished risk of target-related toxicity (Wold et al. 2018).
