Liquiritin apioside is an orally active inhibitor of TRPV1 receptor. Liquiritin apioside selectively inhibits laryngeal chemoreflex (LCR) and has no significant effect on mechanoreflex (LMR). Liquiritin apioside inhibits LCR by inhibiting reactive oxygen species (ROS) and NADPH oxidase, weakening the interaction between ROS and TRPV1. Liquiritin apioside can be used in the research of respiratory-related diseases.

Description

In Vitro

Superior laryngeal nerve (SLN) related electrophysiological experiments: Liquiritin apioside (0.1 mM; overnight) can significantly change the electrophysiological kinetics of laryngeal C neuron currents induced by 1.5 μM Capsaicin (HY-10448P)，reducing the current amplitude, increasing the rise time and prolonging the decay time^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Viability Assay^[1]

Cell Line:	Laryngeal C-neurons (isolated from nodose/jugular ganglia of rat pups)
Concentration:	0.1 mM
Incubation Time:	Overnight; with 1.5 μM Capsaicin
Result:	Inhibited the CAP-induced currents in laryngeal C-neurons. Reduced the current amplitudes, increased the rise times, and prolonged the decay times. Of the eighteen laryngeal C-neurons tested, three neurons (16%) were not CAP-responsive.

In Vivo

Liquiritin apioside (10 μg/μL, intralaryngeal or perineural administration; single dose; 10 min, 20 min) significantly attenuates the apnea, hypertension, and bradycardia responses to the laryngeal chemoreflex (LCR) induced by Capsaicin (HY-10448), hydrochloric acid (HCl), and distilled water (DW) in rat pups, but has no significant effect on the laryngeal mechanoreflex (LMR) induced by air pulse (AP) ^[1].
Liquiritin apioside (0.01 g/kg, 0.2 g/kg; po; once daily for 10 days) ameliorates DSS-induced colitis in mice, and modulates the gut microbial diversity and composition^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:	Laryngeal reflexe study in Sprague-Dawley rat (250-350 g) pups^[1]
Dosage:	10 μg/μL (diluted in saline)
Administration:	Intralaryngeal perfusion for 10 minutes or peri-treatment for 20 minutes, single dose
Result:	Significantly reduced the apneic responses to CAP, HCl, and DW, as well as attenuated the hypertension and bradycardia responses to these stimuli. Did not change the cardiorespiratory responses to AP. Peri-SLN treatment with Liquiritin apioside also suppressed the apnea, hypertension, and bradycardia responses to CAP, HCl, and DW, similar to the effect of intralaryngeal treatment.

Animal Model:	DSS-induced colitis model in C57BL/6 mice (male, 18–22 g, 8–10 weeks)^[2]
Dosage:	0.01 g/kg, 0.02 g/kg (diluted in saline)
Administration:	Oral gavaged for 10 days, once daily
Result:	Exhibited the same pathological changes as that of the ABX (DSS) group mice, specifically, comparable weight loss, DAI score, colon length, and histology score.

In Vivo:

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.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (4.54 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.
Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (4.54 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 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.
Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 2.5 mg/mL (4.54 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.
