Stachydrine hydrochloride promotes the protein expression of IL-12 and IL-6, as well as the mRNA expression of T-bet and RORγt, while inhibiting the mRNA expression of GATA-3 and Foxp3; the Th1/Th2/Th17/Treg paradigm induced by Stachydrine hydrochloride contributed to the reduction in uterine bleeding in RU486-induced abortion mice.

4-O-trans-caffeoylquinic acid is a cinnamate ester obtained by formal condensation of the carboxy group of trans-caffeic acid with the 4-hydroxy group of (+)-quinic acid. It has a role as a metabolite and a hepatoprotective agent. It is a cinnamate ester and a cyclitol carboxylic acid. It is functionally related to a trans-caffeic acid and a (+)-quinic acid.

Cephaeline is a pyridoisoquinoline comprising emetam having a hydroxy group at the 6'-position and methoxy substituents at the 7'-, 10- and 11-positions. It is a conjugate base of a cephaeline(2+). It derives from a hydride of an emetan. Cephaeline was highly active against protected primary CLL cells (relative IC50's 35 nM ) and acted by repressing HIF-1α and disturbing intracellular redox homeostasis.
