Adapalene (Differin; Adaferin; CD271; Adapaleno; ADAPALENE; Adapalenum), structurallysimilar to vitamin A, is a synthetic, retinoic acid analog acting as a dual RAR and RXR agonist with potential anticancer activity. It activates RAR and RXR with EC50 values of 2.2, 9.3, 22 and > 1000 nM for RARβ, RARγ, RARα and RXRα receptors respectively, it is a third-generation topical retinoid mainly used in the treatment of acne. Adapalene inhibits proliferation and induces apoptosis in colorectal cancer cells in vitro and displays comedolytic activity.
| ln Vitro |
The viability of ES-2, HOV-7, MCF-7, Hela, SW1990, HT1080, and MM-468 cells is inhibited by Adapalene (1 - 200 μM; 24 h) with IC50 values of 10.36 μM, 10.81 μM, 12.00 μM, and 19.08, in that order. 19.52 μM, 21.70 μM, 31.47 μM, and μM[2]. Adapalene (10–40 μM; 24 h) decreases proliferation in vitro and causes apoptosis in ES-2 cells [2]. In LoVo or DLD1 cells, adipalene (3-30 μM; 6-24 hours) dramatically raises the G1 phase population [3]. GOT1 activity is inhibited by dipalene (1 - 200 μM) with an IC50 of 21.79 μM[2]. Transglutaminase type I, an enzyme linked to the plasma membrane, is inhibited by adipalene (10-6-10-3 nM), having an IC of 50 2.5 nM[1].

| ln Vivo |
In BALB/C nude mice, adapalene (15–100 mg/kg; orally administered daily for 21 days) inhibits the growth of xenograft tumors derived from DLD1 cells [3].

Apoptosis Analysis[2] Cell Types: ES -2 cells[2] Tested Concentrations: 10, 20, 40 μM Incubation Duration: 24 hrs (hours) Experimental Results: demonstrated a significant increase in apoptosis compared with the control group. Down regulated the expression of anti-apoptotic protein Bcl-2 and PARP. Cell Cycle Analysis[3] Cell Types: LoVo or DLD1 cells Tested Concentrations: 3, 10, 30 μM Incubation Duration: 6, 12, 24 hrs (hours) Experimental Results: Caused cell cycle arrest in G1 phase in a dose- and time-dependent manner. |
| Animal Protocol |

| Solubility (In Vivo) |
Solubility in Formulation 1: 1 mg/mL (2.42 mM) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), suspension solution; with sonication.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 10.0 mg/mL clear DMSO stock solution to 400 μL of PEG300 and mix evenly; then add 50 μL of Tween-80 to the above solution and mix evenly; then add 450 μL of normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 1 mg/mL (2.42 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 10.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly. (Please use freshly prepared in vivo formulations for optimal results.) |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
