TRPA1 Inhibitor

TRPA1 Inhibitors (9):

Cat. No. Product Name Effect Purity
  • HY-W014421
    AP-18
    		Inhibitor 99.61%
    AP-18, a potent and selective TRPA1 inhibitor, blocks activation of TRPA1 by 50 μM Cinnamaldehyde with an IC50 of 3.1 μM and 4.5 μM for human and mouse TRPA1, respectively. AP-18 reverses complete Freund's adjuvant (CFA)-induced mechanical hyperalgesia in mice. AP-18 attenuated 30 μM AITC-induced Yo-Pro uptake in a concentration-dependent manner, with an IC50 of 10.3 μM.
  • HY-171846
    LY3526318
    		Inhibitor 99.92%
    LY3526318 is an orally active, selective TRPA1 antagonist (IC50=5-6μM). LY3526318 blocks TRPA1 channels, inhibits pain signal transduction mediated by the channel, and exerts analgesic activity. LY3526318 is mainly used in the research of chronic pain-related fields, such as diabetic peripheral neuropathy, chronic low back pain, and pain caused by osteoarthritis.
  • HY-153711
    TRPA1-IN-2
    		Inhibitor 99.82%
    TRPA1-IN-2 (compound 1) is a potent and orally active TRPA1 inhibitor with an IC50 value of 0.04 µM. TRPA1-IN-2 shows anti-inflammation activity.
  • HY-P1073
    ProTx-I
    		Inhibitor
    ProTx-I is a toxin derived from Thrixopelma pruriens and a peptide inhibitor targeting TTX-resistant sodium channels. ProTx-I interacts with voltage sensors of multiple domains such as NaV1.7, reduces neuronal excitability through allosteric modulation of channel gating and alteration of voltage dependence. The IC50 values of ProTx-I against human NaV1.7, NaV1.2, NaV1.6, and NaV1.5 are 95 nM, 104 nM, 21 nM, and 358 nM, respectively; ProTx-I also potently inhibits Ba2+ currents of hCav3.1, while its inhibitory potency against hCav3.2 is approximately 160-fold lower. ProTx-I is applicable to the research of chronic pain.
  • HY-162856
    TRPV1-IN-2
    		Inhibitor
    TRPV1-IN-2 ((R)-32) is a TRPV1 inhibitor. TRPV1-IN-2 has protective effects on ED epilepsy models.
  • HY-181762
    Multitarget AD-IN-6
    		Inhibitor
    Multitarget AD-IN-6 (Compound 39) is a multi-target inhibitor, with an IC50 of 15.54 μM against PDE4B, 15.15 μM against PDE7A, 8.39 μM against PDE3A, and a Kd of 37.7 μM against CHIT1. Multitarget AD-IN-6 acts as a TRPA1 antagonist, reduces the level of the NLRP3 inflammasome multiprotein complex to inhibit its activation, while inhibiting PDE4B, PDE7A and CHIT1, and decreasing the phosphorylation of NF-κB. Multitarget AD-IN-6 improves the pathology of elastase-induced emphysema in mice. Multitarget AD-IN-6 is applicable for the research of chronic obstructive pulmonary disease.
  • HY-170652
    ZQMT-10
    		Inhibitor
    ZQMT-10 is an orally active and potent antagonist of TRPA1, with the Kd of 1.04 μM. ZQMT-10 plays an important role in cancer research.
  • HY-122692
    TRPV4/TRPA1-IN-1
    		Inhibitor
    TRPV4/TRPA1-IN-1 is a TRPV4/TRPA1 inhibitor that suppresses TRPV4/TRPA1-mediated calcium influx. TRPV4/TRPA1-IN-1 alleviates pain behaviors in a mouse trigeminal stimulation pain model and inhibits inflammation and pain-related behaviors in a mouse acute pancreatitis model. TRPV4/TRPA1-IN-1 can be used in research on acute pancreatitis.
  • HY-159134
    TRPA1-IN-3
    		Inhibitor 99.66%
    TRPA1-IN-3 (commound 1) is a TRPA1 inhibitor. TRPA1-IN-3 can be used in skin and respiratory tract related research.
