BRF110
BRF110 is an orally active, blood-brain barrier-penetrant Nurr1-RXRα heterodimer activator with an EC50 of 0.9 μM in human systems. BRF110 increases the mRNA level of BDNF, upregulates the transcription of TH, AADC and GCH1 to elevate striatal dopamine levels. BRF110 exhibits neuroprotective activity against MPP+-induced cytotoxicity. BRF110 prevents dopaminergic neuron death, protects nerve cells from toxic damage, and improves motor coordination in mouse models. BRF110 can be used in research related to Parkinson's disease.

BRF110 (0.5-12.5 μM; 12 h) exhibits much higher selectivity for the Nurr1-RXRα heterodimer than for other RXRα heterodimers and homodimers in human SH-SY5Y neuroblastoma cells, and only partially activates the Nur77-RXRα heterodimer[1].

BRF110 (12.5 μM; 0-9 h) transiently induces BDNF expression in human SH-SY5Y neuroblastoma cells via a Nurr1-dependent mechanism, in which Nurr1 and RXRα directly bind to BDNF promoter IV[1].
BRF110 (0.5, 12.5 μM; 24 h) only induces a slight upregulation of SREBP-1c expression by approximately 5-fold in human HepG2 hepatocytes at the concentration of 12.5 μM[1].
BRF110 (12.5 μM) upregulates the expression of key dopamine (DA) biosynthesis genes (TH, AADC, GCH1) in SHSY-5Y cells by activating Nurr1:RXRα[2].
BRF110 (12.5 μM; 24 h, 14 d) protects human induced pluripotent stem cell (iPSC)-derived dopaminergic (DAergic) neurons against MPP+-induced death and restores impaired neurite morphology in LRRK2G2019S dopaminergic neurons derived from patients with Parkinson's disease (PD)[2].

BRF110 (15 mg/kg; p.o.; single administration) increases the level of BDNF mRNA in mouse brains by approximately 25%[1].
BRF110 (10 mg/kg; i.p.; once every 12 hours; for 6 consecutive days) exerts neuroprotective effects against acute MPTP (HY-W114750)-induced Parkinson's disease in C57BL/6 mice, increasing the survival rate of TH (+) midbrain neurons by 31%, doubling the retention rate of striatal axon terminals, and improving motor coordination by more than 100%[2].
The neuroprotective effect of BRF110 (10 mg/kg, i.p., once every 12 hours for 6 days) against MPTP-induced Parkinson's disease in 129SV mice depends on functional Nurr1: it increases the survival rate of TH (+) midbrain neurons in wild-type mice, but shows no effect in Nurr1+− mice[2].
