Background

Tolbutamide is a potent inhibitor of cAMP with an IC50 value of 4mM [1].

Tolbutamide has been reported to inhibit both the basal and the cyclic AMP-stimulated protein kinase activites with an IC50 value of 4mM for cyclic AMP-dependent kinase activity. In addition, Tolbutamide has been revealed to inhibit both soluble and membrane-bound protein kinase from canine heart. Moreover, the Tolbutamide inhibition of adipose tissue cyclic AMP- dependent protein kinase is explanation for antilipolytic effects [1]. Besides, Tolbutamide and dbcAMP has been exhibited to increase about four-fold levels of Cx43 mRNA and decrease about 80% the expression of Ki-67 [2].
