In Vitro

Capsaicin (50-300 μM; 24-72 hours) shows an augmented decrease in cell growth in a dose- and time-dependent manner. The observed IC₅₀ value is around 150 μM^[2].
Capsaicin (50-300 μM; 24-72 hours) shows increase in cytosolic cytochrome c, activation of caspase 3 and PARP (p85) levels, and decreases anti-apoptotic Bcl-2 protein and increases pro-apoptotic Bad/Bax expression^[2].
Capsaicin increases the nuclear condensation, nuclear DNA fragmentation and sub-G1 DNA content^[2].
Capsaicin suppresses the cell cycle progression at the G1/S phase in FaDu cells by decreasing the expression of the regulators of cyclin B1 and D1, as well as cyclin-dependent protein kinases cdk-1, cdk-2 and cdk-4^[2].

In Vivo

Note:
Please do not refer to only one article to determine the experimental conditions. It is recommended to determine the optimal experimental conditions (animal strain, age, dosage, frequency and cycle, detection time and indicators, etc.) through preliminary experiments before the formal experiment.

Capsaicin suppresses the development of lung carcinoma by amending the protein expressions of apoptotic regulators p53, Bcl-2, Bax and caspase-3^[2].
Capsaicin (2 μg in 40 μL per mice, injected into the plantar surface of the left hind paw) induces pain-related behaviour in mice^[4].
Capsaicin (3-30 μg in 10 μL per rat, plantar injection) induces secondary mechanical hypersensitivity (SMH) (used clinically as a model to potentially predict neuropathic pain) in rats^[5].
Capsaicin (0-500 μg in 25 μL per rat, injected subcutaneously into the center of the right vibrissae pad) induces pain in the orofacial region or rats^[6].
In high dose, Capsaicin may should be adminstered under anesthesia condition^[7]^[8].
Capsaicin is more pungent than Dihydrocapsaicin (HY-N0361)^[9].
Note: The spicy taste is choking, please take precautions.

Stock Solution Working Solution

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% EtOH 90% Corn Oil

Solubility: 20 mg/mL (65.49 mM); Suspended solution; Need ultrasonic

This protocol yields a suspended solution of 20 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.

Taking 1 mL working solution as an example, add 100 μL EtOH stock solution (200.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Protocol 2

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline

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.

Protocol 3

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)

Solubility: ≥ 2.5 mg/mL (8.19 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.

Protocol 4

Add each solvent one by one: 10% DMSO 90% Corn Oil

Solubility: ≥ 2.5 mg/mL (8.19 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.

Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
