NGI-1 is a a cell-permeable inhibitor of oligosaccharyltransferase (OST).can effectively reduce virus infectivity without affecting cell viability.

PAR3 (1-6) is a synthetic peptide agonist of proteinase-activated receptor 1 (PAR1) that corresponds to residues 1-6 of the amino terminal tethered ligand sequence of human PAR3 and residues 39-44 of the full-length human sequence. PAR3 (1-6) activates p42/44 MAPK signaling in fibroblasts expressing PAR1, but not PAR3, an effect that can be blocked by the PAR1 antagonist RWJ 56110.

Isobavachin can facilitate mouse ES cells differentiating into neuronal cells.
