Geniposide is an iridoid glycoside with a variety of biological activities including neuroprotective, anti-diabetic, antiproliferative, and antioxidative activity. Geniposide has been shown to regulate Nrf2 translocation.

Methyl tridecanoate is a natural product.

Qingyangshengenin B (Otophylloside B) is a C-21 steroidal glycoside isolated from Qingyangshen. Qingyangshengenin B protects against Aβ toxicity, which decreases Aβ deposition by decreasing the expression of Aβ at the mRNA level. Qingyangshengenin B has antiepileptic and anti-aging effects, it can extend lifespan, increase heat stress-resistance, delay body paralysis, and increase the chemotaxis response in C. elegans models of Alzheimer's disease. Otophylloside B can suppress the seizure-like locomotor activity caused by pentylenetetrazole in zebrafish.

JLK6 was a gamma-secretase inhibitor that does not interfere with Notch signalling

Aftin-4, an amyloid forty-two inducer, activates γ-secretase, promoting the generation of amyloid-β-1-42 (Aβ1-42) from amyloid-β protein precursor. Aftin-4(Aftin4) increased Aβ-1-42, but not Aβ-1-40 in mouse hipppocampus, accompanied by learning deficits and mitochondrial ultrastructural changes similar to those found in the brains of patients with AD. Aftin-4(Aftin4) can thus be used to induce a rapid, acute Alzheimer's disease-like toxicity in the rodent brain.

Dihydroergocristine mesylate (DHEC (mesylate))(DHEC mesylate) is the methanesulfonic acid salt of dihydroergocristine. It has been used as the for the symptomatic treatment of mental deterioration associated with cerebrovascular insufficiency and in peripheral vascular disease. Dihydroergocristine mesylate is a inhibitor of γ-secretase (GSI), , reduces the production of the Alzheimer's disease amyloid-β peptides, binds directly to γ-secretase and Nicastrin with equilibrium dissociation constants (Kd) of 25.7 nM and 9.8 μM, respectively[1]. It is also a component of ergoloid mesylate (codergocrine mesilate), a mixture of ergot alkaloid derivatives that is used as a vasodilator and has shown mild benefits in the treatment of vascular dementia. It has a role as a vasodilator agent, an alpha-adrenergic antagonist and a geroprotector. It contains a dihydroergocristine.
