LG100268 (LG268) is a potent, selective and orally active retinoid X receptor (RXR) agonist with EC50 values of 4 nM, 3 nM, and 4 nM for RXR-α, RXR-β, and RXR-γ, respectively. LG100268 displays >1000-fold selectivity for RXR over RAR, the Ki values are 3.4 nM, 6.2 nM and 9.2 nM for RXR-α, RXR-β, and RXR-γ, respectively. LG100268 activates RXR homodimers to induce transcriptional activation. LG100268 can be used for the study of lung carcinogenesisy.
体外研究
LG100268 (100 nM-1 μM; 24 hours) shows a downregulation of CSF3 and a 2.5-fold decrease of CXCL2 and IL-1β mRNA expression in RAW264.7 cells.
Cell Viability Assay
Cell Line:
RAW264.7 cells
Concentration:
100 nM-1 μM
Incubation Time:
24 hours
Result:
Decreased LPS induced cytokine mRNA levels.
体内研究
LG100268 (oral diet; 100 mg/kg; once daily; 7 weeks) combines with C/P presents a more markedly reduced average tumor burden than LG268 or C/P alone. The combination establish a reduced lung tumors, which represents a reduction of 82% (vs. 59%-67% with the single drugs) in comparison with the controls.
Animal Model:
A/J mice
Dosage:
50 mg/kg (Combines with carboplatin (50 mg/kg i.p.) starts 1 week after the LG268 treatment diet)
Administration:
Oral diet; once daily; 7 weeks
Result:
Decreased lung tumors growth significantly in mice.
