Crotamiton
Based on 1 Customer Validation
Crotamiton is a TRPV4 inhibitor. Crotamiton inhibits TRPV4 currents. Crotamiton inhibits TRPV4 selective agonist-induced pruritus-related behaviors in mice. Crotamiton inhibits Histamine- and Chloroquine-induced calcium influx via the H1R/TRPV1, MRGPRA3/TRPA1 pathways, and also suppresses calcium influx in primary mouse dorsal root ganglion neurons. Crotamiton is applicable to research related to pruritus, scabies, and non-scabietic pruritus.

Crotamiton (0-500 μM) potently inhibits GSK1016790A-activated mTRPV4 currents in HEK293T cells under the condition of 2 mM extracellular Ca2+ in vitro, with IC50 values of 15.5 μM and 16.3 μM in mouse and human, respectively[1].
Crotamiton (100-1000 μM) inhibits mTRPV4 currents activated by GSK1016790A in HEK293T cells cultured in calcium-free medium, with an IC50 of 223.5 μM[1].
Crotamiton (0-1000 μM) inhibits TRPV4 currents in GSK1016790A-activated NHEK cells in calcium-free medium[1].
Crotamiton (0-1000 μM) reduces the open probability and unitary amplitude of mTRPV4 single channels in HEK293T cells[1].
Washout after co-treatment with Crotamiton (0-1000 μM; 60 s, co-applied with GSK1016790A) and GSK1016790A induces dilation of the mTRPV4 channel in HEK293T cells, which allows the permeation of large cations up to TetMA+ (6.48 Å diameter), but does not permit the permeation of NMDG (8.90 Å diameter)[1].
Crotamiton (1 mM; 5 min pre-incubation) inhibits histamine (HY-B1204)- and chloroquine (HY-17589A)-induced calcium influx in HEK293T cells expressing H1R/TRPV1 or MRGPRA3/TRPA1, with IC50 values of 101.2 μM and 326.2 μM, respectively. Its mechanism of action functions through the H1R/TRPV1 pathway, rather than directly inhibiting TRPV1[2].

Crotamiton (i.p., 125 mg/kg, single dose) reduces histamine- and chloroquine-induced scratching episodes in male ICR mice[2].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 3.5 mg/mL (17.22 mM); Clear solution
This protocol yields a clear solution of ≥ 3.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (35.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 3.5 mg/mL (17.22 mM); Clear solution
This protocol yields a clear solution of ≥ 3.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (35.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
