One example of a drug that can act as a full agonist is isoproterenol, which mimics the action of adrenaline at β adrenoreceptors. Another example is morphine, which mimics the actions of endorphins at μ-opioid receptors throughout the central nervous system. However, a drug can act as a full agonist in some tissues and as a partial agonist ...
Dopamine agonists act directly on the dopamine receptors and mimic dopamine's effect. [1] Dopamine agonists have two subclasses: ergoline and non-ergoline agonists. Both subclasses target dopamine D 2-type receptors. Types of ergoline agonists are cabergoline and bromocriptine and examples of non-ergoline agonists are pramipexole, ropinirole ...

Beta 2-adrenergic agonists, also known as adrenergic β 2 receptor agonists, are a class of drugs that act on the β 2 adrenergic receptor. Like other β adrenergic agonists , they cause smooth muscle relaxation. β 2 adrenergic agonists' effects on smooth muscle cause dilation of bronchial passages , vasodilation in muscle and liver ...
In addition, depending on the cell type, the specific effect, whether agonist, antagonist, inverse agonist, etc., could have a unique specific effect. An example is seen in insulin, under "Receptor Agonists," as it interacts with multiple different cell types as an agonist, but incites multiple and different responses in both.
Examples of ligands activating peroxisome proliferator-activated receptor gamma as partial agonists are honokiol and falcarindiol. [3] [4] Delta 9-tetrahydrocannabivarin is a partial agonist at CB2 receptors and this activity might be implicated in ∆9-THCV-mediated anti-inflammatory effects. [5]
Modulators that increase only the affinity of partial and full agonists allow their efficacy maximum to be reached sooner at lower agonist concentrations – i.e. the slope and plateau of a dose-response curve shift to lower concentrations. [4] Efficacy increasing modulators increase maximum efficacy of partial agonists.
Vabicaserin is a full agonist with approximately 4-fold greater selectivity for 5-HT 2C over these related receptors, in terms of binding affinity. Vabicacserin is a full agonist in stimulating the 5-HT 2C receptor; it was discovered when a class of tetrahydroquinoline-fused diazepines were being researched as possible potent 5-HT 2C receptor ...
