SJ-300
SJ-300 is a potent and selective, orally active and brain-penetrat DKK3-LRP1 interaction inhibitor. SJ-300 restores Aβ clearance in AD models. SJ 300 binds to mLRPIV with a Kd of 7.9 μM, inhibits the DKK3 mLRPIV complex with an IC50 of 3.2 μM, and does not disrupt the binding of Aβ to LRP1. SJ 300 rescues cognitive function and ameliorates neuropathology (Aβ plaque reduction ≈ 73.3 %) in vivo. SJ 300 can be employed for research in Alzheimer’s disease.

In Vitro
SJ-300 (0-5 μM) exerts a substantial reduction in the DKK3-mLRPIV interaction in SH-SY5Y cells[1].
SJ-300 (1 μM, 2 h) restores Aβ internalization in AD-NSC cells[1].
SJ-300 (10 μM) has no direct impact on the canonical Wnt/β-catenin signaling pathway in SH-SY5Y cell. [1].
SJ-300 (50 μM in 2 μL0-60 min) has superior metabolic stability in mouse and human liver microsomes[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo
SJ-300 (i.g., 10 mg/kg, once) shows a brain-penetration capability with brain/plasma (B/P) ratio = 5732 %[1].
SJ-300 (i.g., 5 mg/kg, once daily for 8 weeks) improves cognitive functions in the 5×FAD transgenic mouse (6 months) model of AD, and these improvements associate with reductions in Aβ pathology.[1].
SJ-300 (i.g., 5 mg/kg, once daily for 8 weeks) attenuates cognitive deficits and AD pathologies through enhancing Aβ clearance in 6-month-old 5×FAD mice.[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
