Effect of the antiallergic drug disodium cromoglycate on phosphodiesterase activity.
The antiallergic drug disodium cromoglycate and its non-antiallergic analogue dicoumarol, inhibit the enzymatic activity of phosphodiesterase with KI values of 0.8.10(-9) M and 1.6.10(-9) M, respectively. It seems that the dichromone group is responsible for this inhibition, independently of its antiallergic effect.
