Use of Granuliberin-R

Granuliberin R is a new mast cell degranulating peptide comes from amphibian, can be isolated from the skin of frog Rana rugosa. Granuliberin R is a dodecapeptide, can act on rat peritoneal mast cell to liberate granules and release histamine[1][2].

In Vitro	Granuliberin R (10 μg/mL) does not alter the release of catecholamines and adenine nucleotides from cultured adrenal chromaffin cells, while the Mastoparan (10 μg/mL) increases both of them[3].
In Vivo	Granuliberin R (0.1 mg/mL, 1 μg/mL, and 10 ng/mL; injection; single dose for 60 s) interfere in the proliferation of oral keratinocytes and the activity of connective tissue cells when treatment is conducted into rats mandibular gingiva in the vicinity of the right mental foramen[4].
