Crocin-4
Crocin-4, a carotenoid constituent of saffron, is a potent and brain-penetrant antioxidant agent. Crocin-4 can inhibit the aggregation and the concomitant deposition of Aβ fibrils in the brain. Crocin-4 can be used for the research of Alzheimer's Disease. Crocin-4 also exhibits antitumor and anti-inflammatory activities.

Biological Activity
Crocin-4 (0.1-1000 μM; 24-72 h) do not compromise cell viability of neuron-like cells[1].
Crocin-4 (1 mM; 72 h) reduces total PSEN1, PSEN1 and PSEN2 complexes, BACE1, APP-C99 and sAPPα, while it increases PSEN1-CTF and PSEN2 in SH-SY5Y-APP cells[1].
Crocin-4 (1 mM; 72 h) suppresses GSK3β and ERK1/2 kinases in PC12-htau cells, and significantly reduces the levels and phosphorylation of tau on the pThr231 and pSer199/Ser202 epitopes[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Line:Differentiated SH-SY5Y-APP cells
-
Concentration:1 mM
-
Incubation Time:72 hours
-
Result:Significantly reduced total PSEN1 by 19%, and the PSEN1 and PSEN2 complexes by 81 and 65%, while it increased PSEN1-CTF (26%) and PSEN2 (43%).
The key molecules of the amyloidogenic pathway, BACE1 and APP-C99 were significantly reduced by 20 and 28%, respectively.
The non-amyloidogenic pathway product sAPPα was also reduced, by 44%, while APP-C83 remained unaltered.

-
Concentration:1 mM
-
Incubation Time:72 hours
-
Result:Significantly reduced total tau levels (by 32%) and tau phosphorylation (pThr231 and pSer199/Ser202-tau by 22 and 75%, respectively).
Downregulates the active and inactive forms of GSK3β (total GSK3β by 34%, pSer9-GSK3β by 30%) and ERK1/2 (total ERK2 by 37%, pERK1 by 40%, pERK2 by 50%).
