Intrinsic activity of an agonist potency

WebThe activity of the two stereoisomers was carefully examined on PPARα and PPARγ subtypes. As expected, both showed partial agonist activity toward PPARγ; the investigation of PPARα activity, however, led to unexpected results. In particular, (S)‐2 was found to act as a partial agonist, whereas (R)‐2 behaved as an antagonist. WebJun 21, 2024 · It has affinity but intrinsic activity between 0 to -1 (example, β-carbolines). Partial agonists. The drug binds to the receptor but produces an effect less than that of an agonist in the body. They inhibit the effect of agonist drugs. It has affinity but less intrinsic activity (e.g. buprenorphine and pindolol).
