Biological Activity

[Description]:

Stepronin (Prostenoglycine) is an orally active expectorant (inhalation administration is preferable to oral administration). Stepronin inhibits airway secretion in vitro by reducing Cl- secretion from epithelial cells and mucus glycoprotein secretion from submucosal glands[1].

[In Vitro]

Stepronin (0.1-100 µM; 20 min) induces significant reductions in ISOP(Isoproterenol)-evoked SCC (short circuit current) value in a dose-dependent manner in canine tracheal epithelium[1]. Stepronin (10-100 µM; 20 min) significantly inhibits the basal secretion and ISOP-evoked PD (potential difference) value in a dose-dependent manner in canine tracheal epithelium[1]. Stepronin (100 µM; 20 min) significantly inhibits ISOP-induced [3H]-glycoconjugate secretion in submucosal glands[1]. Cell Viability Assay[1] Cell Line: Canine tracheal epithelium (from adult and 10 to 25 kg-weight mongrel dogs of both sexes) Concentration: 0.1-100 µM; 10-100 µM Incubation Time: 20 min (pre-treat) Result: Significantly inhibited ISOP-induced SCC and PD values, as well as basal secretion. Cell Viability Assay[1] Cell Line: Submucosal glands (from adult and 10 to 25 kg-weight mongrel dogs of both sexes) Concentration: 100 µM Incubation Time: 20 min (pre-treat) Result: Significantly inhibited ISOP- induced [3H]-glycoconjugate secretion.
