AP 18

Catalog No. T21543Cas No. 55224-94-7

AP-18 is a potent and selective TRPA1 inhibitor. AP-18 inhibits activation of TRPA1 induced by 50 μM Cinnamaldehyde with an IC50 of 3.1 μM and 4.5 μM for human and mouse TRPA1, respectively. AP-18 could reverse complete Freund's adjuvant (CFA)-induced mechanical hyperalgesia in mice. AP-18 could attenuate Yo-Pro uptake induced by 30 μM AITC in a concentration-dependent manner (IC50= 10.3 μM).

Product Introduction

Bioactivity
Description
AP-18 is a potent and selective TRPA1 inhibitor. AP-18 inhibits activation of TRPA1 induced by 50 μM Cinnamaldehyde with an IC50 of 3.1 μM and 4.5 μM for human and mouse TRPA1, respectively. AP-18 could reverse complete Freund's adjuvant (CFA)-induced mechanical hyperalgesia in mice. AP-18 could attenuate Yo-Pro uptake induced by 30 μM AITC in a concentration-dependent manner (IC50= 10.3 μM).
In vitro
At concentrations up to 50 μM, AP-18 does not significantly inhibit the activation of TRPV1, TRPV2, TRPV3, TRPV4, or TRPM8. However, it effectively and reversibly inhibits the activation of mouse TRPA1 by iodoacetamide (an irreversible cysteine-alkylating agent) in CHO cells, as determined through ratiometric Ca2+ imaging. Additionally, AP-18 prevents cold- and mustard-oil-triggered activation of mouse TRPA1 and inhibits TRPA1 currents induced by cinnamaldehyde in Xenopus oocyte excised patches, demonstrating its specificity and effectiveness in modulating TRPA1 activity [1] [2] [3].
In vivo
AP18 (1 mM; injected in the hindpaw of mice) effectively inhibits nociceptive events triggered by cinnamaldehyde, but not those induced by capsaicin, demonstrating its specificity and efficacy [1].

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the mother liquor preparation method and in vivo formula preparation method:
TargetMol | Animal experimentsFor example, your dosage is 10 mg/kg Each animal weighs 20 g, and the dosage volume is 100 μL . TargetMol | Animal experiments A total of 10 animals were administered, and the formula you used is 5% TargetMol | reagent DMSO+30% PEG300+5% Tween 80+60% ddH2O. So your working solution concentration is 2 mg/mL。
Mother liquor preparation method: 2 mg of drug dissolved in 50 μL DMSOTargetMol | reagent (mother liquor concentration of 40 mg/mL), if you need to configure a concentration that exceeds the solubility of the product, please contact us first.
Preparation method for in vivo formula: Take 50 μL DMSOTargetMol | reagent main solution, add 300 μLPEG300TargetMol | reagent mix well and clarify, then add 50 more μL Tween 80, mix well and clarify, then add 600 more μLddH2OTargetMol | reagent mix well and clarify
For Reference Only. Please develop an appropriate dissolution method based on your laboratory animals and route of administration.
