Human Endogenous Metabolite

 

体外研究(In Vitro)

Isotretinoin (13-cis-Retinoic acid) may act as a pro-drug that is converted intracellularly to metabolites that are agonists for RAR and RXR nuclear receptors.
Isotretinoin is highly sensitive to air, heat, and light.
Isotretinoin (0-40 μM; 24-96 h) significantly inhibits HepG2 cell viability.
Isotretinoin (10 μM; 48 h) down-regulates c-MYC mRNA expression and this is partially due to P1 or P2 promoter activity.

Medlife has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Viability Assay

Cell Line: HepG2
Concentration: 0.1, 0.5, 1, 5, 10, 20, and 40 μM
Incubation Time: 24, 48, 72, and 96 h
Result: Showed a significant reduction in cell viability (less than 30%) at 96 h for all doses.

RT-PCR

Cell Line: HepG2
Concentration: 10 μM
Incubation Time: 48 h
Result: Significantly reduced the expression of c-MYC mRNA by ~80%.
体内研究(In Vivo)

Isotretinoin (13-cis-Retinoic acid) (1.3-481 μg/L; inhalation exposure; 45 min daily for 2 weeks) is an effective lung cancer chemopreventive agent in A/J Mice.
Isotretinoin accelerates alveolar repair after exodontia in rats.

Medlife has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Male A/J mice, lung carcinogenesis model
Dosage: 1.3, 20.7, or 481 μg/L
Administration: Inhalation exposure, 45 min daily for 2 weeks
Result: Reduced the tumor multiplicity. Caused up-regulation of lung tissue nuclear retinoic acid receptors (RARs) relative to vehicle-exposed mice, RARα (3.9-fold vehicle), RARβ (3.3-fold), and RARγ (3.7-fold) at 20.7 μg/L.
Animal Model: Wistar rats, tooth extraction model
Dosage: 7.5 mg/kg
Administration: Oral gavage, daily for 30 days
Result: Accelerated the process of alveolar repair, significantly decreased serum calcium levels.
