JI051 is an antitumor agent that interacts with the cancer-associated protein chaperone prohibitin 2 (PHB2) to induce cell cycle arrest by inhibiting the transcription of the Notch downstream effector gene, Hes1, and inhibits the proliferation of HEK293 cells and pancreatic cancer cells.

This peptide is a fragment of the JAG-1 protein. JAG-1 is Notch ligand, a peptide that is the most conspicuously expressed ligand in skin. JAG-1 induces epidermal maturation. Exposing submerged keratinocytes monolayers to JAG-1 with elevated calcium concentration produces stratification with loricrin expression and NF-αB activation.

5β-Cholanic acid (5beta-Cholanic acid) is a potent γ-secretase modulator used in Alzheimer's disease research.
