Human urocortin (hUcn) II is a new member of the corticotropin-releasing-factor (CRF) family. It selectively binds to the CRF2 receptor. Human urocortin II exhibits mild motor-suppressive effects and delayed anxiolytic-like effects，suggesting a time-dependent role for hUcn II in the regulation of stress-related behavior.

Substance P (7-11) is a C-terminal fragment of Substance P, which can cause an increase in the intracellular calcium concentration as measured by the fluorescent dye Fura-2. In addition, the C-terminal fragment of SP, SP-(7-11), increased PGE2 and collagenase production at concentrations greater than 1 mM.

Cajanin has potential hypolipidemic effects,possibly via up-regulating the ABCA1 protein expression,subsequently resulting in increased macrophage cholesterol efflux and RCT, it can significantly improve basal glucose uptake in HepG2 cells, its improving effect is concentration dependent, it exhibits effects stronger than that of rosiglitazone, which has been used as an antidiabetic drug.
