Background

Tretinoin(Aberela) is retinoic acid in pharmaceutical form and used to treat acne vulgaris and keratosis pilaris.

In cultured human mesangial cells, tretinoin increased the reduced glutathione content and the catalase activity in a dose- and time-dependent way, which then prevented the cytotoxicity of H2O2 [1].

In old male Fischer 344 rats, tretinoin inhibited the expression of TNF-β1 and osteopontin (a protein with chemotactic and cell adhesive properties) in the renal cortex [1]. In male NMRI-mice treated with 1×109 sheep red blood cells (SRBCs), tretinoin markedly inhibited cellular immunity and increased humoral immunity. Tretinoin reduced lymphocyte proliferation, NBT reduction and the secretion of interleukin-17, but increased the production of interleukin-10 [2]. In patients with facial acne, clindamycin phosphate Tretinoin Gel (CTG) (1.2% clindamycin phosphate, 0.025% tretinoin in a gel base (Velac)) was significantly more effective than 0.025% tretinoin, which relayed on the anti-inflammatory efficacy of tretinoin [3].

Protocol

Cell experiment [1]:

Cell lines

Mesangial cells

Preparation method

The solubility of this compound in DMSO is > 11.9 mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37 °C for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below - 20 °C for several months.

Reacting condition

0 ~ 25 μM; 0 ~ 24 hrs

Applications

Tretinoin prevented H2O2-induced cell damage by increasing both the catalase activity and the reduced glutathione level in dose- and time-dependent manners. In mesangial cells, Tretinoin increased the levels of catalase mRNA and gamma-glutamyl-cysteine synthetase (catalytic subunit) mRNA, the latter being involved in the rate-limiting step for the de novo synthesis of reduced glutathione.

Animal experiment [1]:

Animal models

Male Fischer 344 rats

Dosage form

1 mg/kg/day; p.o.

Applications

In male Fischer 344 rats, Tretinoin at the dose of 1 mg/kg/day did not caused any toxic effect. Compared with age-matched control animals, rats treated with Tretinoin showed lower protein content in the renal cortex. But there was no difference in the DNA content of the renal cortex between the control group and the Tretinoin treatment group.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
