    Abstract:
    The relationship of binding to protein and hypoglycemic activity of 11 sulfonamide derivatives of 2-pyrazoline-1-carboxamide was tested. It has been shown that the hypoglycemic effect of the most potent compound of the series, SPC-703, is related to the unbound, but not to the total concentration of the drug in the rat serum. Binding to albumin increased with the increase of hydrophobic properties of the compounds investigated. The increased affinity to albumin may be responsible for low hypoglycemic activity of some of the compounds tested.
