生物活性:
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.

体内研究:
Crocin-4 (50 mg/kg; i.p.) is capable of crossing the Blood Brain Barrier (BBB) and build up levels in the mouse brain.

体外研究:
Crocin-4 (0.1-1000 μM; 24-72 h) do not compromise cell viability of neuron-like cells.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.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.
