DHICA
Based on 1 Customer Validation
DHICA (5,6-Dihydroxyindole-2-carboxylic acid) is an eumelanin building block, GPR35 agonist and melanin synthesis intermediate. DHICA activates GPR35, triggering dynamic mass redistribution and β-arrestin translocation. DHICA interacts with DNA and interferes with Fpg activity. DHICA promotes the generation of single-strand breaks in plasmid DNA. DHICA increases the activity and expression levels of SOD and Catalase. DHICA is applicable to research related to skin cancer and colon cancer.

In Vitro
DHICA acts as a GPR35 agonist in native HT-29 colon cancer cells, triggering a DMR response with an EC50 of 23.6 ± 2.5 μM[1].
DHICA (5-50 μM; 24-72 h) inhibits the proliferation of primary normal human keratinocytes in a dose- and time-dependent manner[3].
DHICA (25-50 μM; 24-48 h) dose-dependently promotes the differentiation of primary normal human keratinocytes by upregulating the mRNA and protein expression of early and late differentiation markers[3].
DHICA (5-50 μM; 24-48 h) increases the activity and protein expression levels of the antioxidant enzymes SOD and catalase in primary normal human keratinocytes in a dose- and time-dependent manner[3].
DHICA (5-50 μM) protects primary normal human keratinocytes against UVA-induced cell damage, lipid peroxidation, and apoptosis[3].

Solvente y solubilidad
In Vitro:
DMSO : 50 mg/mL (258.85 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

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.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (12.94 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.

Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
μL , mix evenly;
3. Then add μL Tween 80, mix evenly;
4. Then add μL
Please ensure that the stock solution in the first step is dissolved to a clear state, and add co-solvents in sequence. You can use ultrasonic heating (ultrasonic cleaner, recommended frequency 20-40 kHz), vortexing, etc. to assist dissolution.
