N-dodecanoyl-L-Homoserine lactone is a quorum sensing (QS) signaling molecule, a microbial communication mechanism modulated by acyl homoserine lactone (AHL) molecules impacts biofilm formation in bioreactors.

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.

PUMA BH3 is a p53 upregulated modulator of apoptosis (PUMA) BH3 domain peptide, acts as a direct activator of Bak, with a Kd of 26 nM.This is a PUMA BH3 domain peptide. PUMA proteins bind Bcl-2, localize to the mitochondria, and induce cytochrome C release and apoptosis in response to p53. PUMA may be a direct mediator of p53-induced apoptosis.
