Biological Activity

Description Adapalene (CD-271) is a dual RAR and RXR agonist, used in the treatment of acne.
Targets
RARγ [1] RARβ [1] RXR [1]
In vitro
In vitro Adapalene binds to retinoic acid receptors found predominantly in the terminal differentiation zone of epidermis and is more active than tretinoin in modulating cellular differentiation. Adapalene shows greatest affinity for the subtype PARγ, found predominantly in the epidermis. Adapalene is more active than indomethacin, betamethasone valerate, tretinoin, isotretinoin or etretinate in inhibiting lipoxygease activity, but it has little activity against cyclo-oxygenase. [1] Adapalene time- and dose-dependently suppresses DNA synthesis and induces apoptosis in Colon carcinoma cell lines CC-531, HT-29 and LOVO as well as human foreskin fibroblasts. Adapalene shows significantly more effective antiproliferative and proapoptotic effects than 9-cis-retinoic acid (CRA), showing remarkable effects even at 10 μM. Adapalene disrupts DeltaPsi(m) and induces caspase-3 activity in responsive tumor cells. [2]
In Vivo
In vivo Adapalene produces a dose-related reduction in the number of epidermal comedones and an increase in comedo profile and epidermal thickness in the rhino mice. [1] Adapalene results in a decreased expression of TLR-2 and IL-10 in explants of normal skin and explants of acne. Adapalene can modulate the epidermal immune system by increasing the CD1d expression and by decreasing the IL-10 expression by keratinocytes, and these modulations can increase the interactions between dendritic cells and T lymphocytes and could strengthen the antimicrobial activity against Propionibacterium acnes.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid 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 master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
