although the insulin-increased camp pde exhibits the same sensitivity as control pde from untreated preparations to isobutylmethyl xanthine , a nonspecific pde inhibitor , and m & b 22,948 , a relatively selective cyclic gmp pde inhibitor , differences in the degree of inhibition of pde activity are seen in the insulin-treated and untreated preparations with the low km camp pde inhibitors ro20-1724 , rolipram , amrinone and milrinone and with cyclic gmp .
