CB2 Antagonists (9):

Cat. No. Product Name Effect Purity
  • HY-13439
    Antagonist 99.25%
    SR144528 is a potent and selective CB2 receptor antagonist with a Ki of 0.6 nM.
  • HY-13505
    Antagonist ≥99.0%
    AM281 is a selective CB1 receptor antagonist with an IC50 of 9.91 nM. AM281 inhibits CB2 receptor with an IC50 of 13000 nM.
  • HY-161311
    AChE/BChE-IN-18 (Compound 4g) is a dual inhibitor of AChE/BChE , with a IC50 value of 0.315 μM for AchE. AChE/BChE-IN-18 is also a CB2R antagonist with a Ki value of 31 nM. AChE/BChE-IN-18 has neuroprotective activity.
  • HY-152581
    CB2R antagonist 3
    Antagonist 98.08%
    CB2R antagonist 3 is a selective antagonist of cannabinoid type 2 receptor (CB2R). CB2R antagonist 3 has high affinity for human CB2R and specific selectivity for CB1R. CB2R antagonist 3 can be combined with CB65 (HY-110047), the activator of CB2R. CB2R antagonist 3 effectively up-regulates the expression of anti-inflammatory cytokines and down-regulates the expression of pro-inflammatory cytokines.
  • HY-14788
    Antagonist ≥99.0%
    Drinabant (AVE1625) is an orally active CB1 receptor antagonist. Drinabant (AVE1625) inhibits the agonist-stimulated calcium signal with IC50 values of 25 nM and 10 nM for the hCB1-R and rCB1-R, respectively, and is ineffective for the hCB2-R.
  • HY-146134
    Antagonist 99.74%
    PGN36 (Compound 18) is a selective cannabinoid CB2 receptor (CB2R) antagonist with a Ki of 0.09 µM.
  • HY-W011040
    LY320135 is a potent and selective antagonist of CB1 receptor, with a Ki of 141 nM. LY320135 also binds to 5-HT2 and muscarinic receptors with Kis of 6.4 μM and 2.1 μM, respectively. LY320135 exhibits neuroprotective effect.
  • HY-133533
    O-2050 is a high affinity cannabinoid CB1 receptor antagonist with a Ki of 2.5 nM. O-2050 inhibits cannabinoid CB2 receptor (Ki=0.2 nM). O-2050 can cause locomotor stimulation in mice.
  • HY-14791
    Ibipinabant (SLV319) is a potent, selective and orally active antagonist of cannabinoid CB1 receptor, with a Ki of 7.8 nM. Ibipinabant shows more than 1000-fold selectivity for CB1 over CB2 (Ki=7943 nM). Ibipinabant can be used for the research of obesity and diabetic.
