| Targets |
Olorinab targets the cannabinoid receptor type 2 (CB2). It is a highly potent and selective CB2 agonist. It exhibits consistent single-digit nanomolar potency and full intrinsic efficacy across multiple species, with strong selectivity for CB2 over CB1 in both binding and functional assays. Olorinab also induces robust CB2 receptor internalization, supporting agonist-driven receptor recycling. By activating CB2, it modulates immune cell signaling and inflammatory responses.

| ln Vitro |
Comprehensive in vitro investigation of Olorinab (APD 371) (6) shows that Olorinab (APD 371) is selective for CB2 in terms of binding and functioning Higher than CB1 test, and that single-digit nanomolar potency and full intrinsic efficacy are maintained across all species evaluated. Additionally, in CHO cells expressing HA-tagged rat CB2, lorinab (APD 371) caused effective receptor internalization (about 106% compared to the CB1/2 agonist CP55,940), indicating that it may be able to drive agonist-driven receptor recycling as hypothesised [1].
In vitro, Olorinab is a highly potent, selective, and fully efficacious CB2 agonist with an EC₅₀ of 6.2 nM for hCB2. Profiling demonstrates consistent single-digit nanomolar potency and full intrinsic efficacy across multiple species, with strong selectivity for CB2 over CB1. It induces robust CB2 receptor internalization. Its effects on immune cell signaling and inflammatory responses have been characterized in cell-based assays. |
| ln Vivo |
At doses ≥3 mg/kg PO, olorinab (APD 371) considerably raises the paw withdrawal threshold (ED50=2.3 mg/kg). A single dosage of Olorinab (APD 371) (10 mg/kg PO) lowered the paw withdrawal threshold for up to 4 hours following delivery in a different experiment. Furthermore, it is possible that CB2 receptor activity mediates Olorinab's (APD 371) analgesic action [1].
In vivo, oral administration of Olorinab produces significant, sustained analgesic effects, increasing paw withdrawal thresholds in a CB2-dependent manner. It reduces chronic pain and inflammation-related symptoms without typical CB1-mediated psychoactive effects. Olorinab has been investigated for the treatment of chronic pain. Its efficacy in pain models highlights its value for pain and inflammation research. |
| Enzyme Assay |
The activity of Olorinab can be assessed using cell-based functional assays. Cells expressing human CB2 receptors are treated with varying concentrations of Olorinab, and the activation of downstream signaling (e.g., inhibition of cAMP production, activation of MAPK pathways) is measured. The EC₅₀ for receptor activation is determined from dose-response curves. Binding affinity and selectivity for CB2 over CB1 are assessed using radioligand binding assays.
|
| Cell Assay |
To evaluate the cellular effects of Olorinab, immune cells (e.g., macrophages, T cells) are treated with the compound. The modulation of cytokine production, chemotaxis, and other immune functions is assessed. CB2 receptor internalization is measured using fluorescently labeled receptor constructs or by flow cytometry. The compound's effects on cell signaling pathways are analyzed by Western blotting.
|
| Animal Protocol |
In vivo studies with Olorinab typically involve administration to animal models via oral routes. In models of chronic pain (e.g., neuropathic pain, inflammatory pain), the compound's analgesic effects are assessed by measuring paw withdrawal thresholds or other pain-related behaviors. Its effects on inflammation are evaluated by measuring inflammatory markers in tissues. Pharmacokinetic parameters, such as oral bioavailability and half-life, are also characterized.
|
| ADME/Pharmacokinetics |
Olorinab has a molecular formula of C₁₈H₂₃N₅O₃ and a molecular weight of 357.41 g/mol. Its CAS number is 1268881-20-4. The purity is typically ≥95%. It is a small molecule agonist of the CB2 receptor. It should be stored according to the manufacturer's instructions.
|
| Toxicity/Toxicokinetics |
Specific toxicology data for Olorinab are not extensively detailed in the available literature. However, as a selective CB2 agonist, it is designed to avoid the psychoactive effects associated with CB1 receptor activation, which may contribute to a more favorable safety profile. As with all research compounds, standard safety precautions should be taken when handling Olorinab.
