In the case of forskolin, it is the opposite:  it activates adenylate
cyclase, thereby INCREASING intracellular cAMP.  A useful reference:

Seamon et al., 1981 "Forskolin:  Unique Diterpene Activator of
Adenylate Cyclase in Membranes and in Intact Cells"  PNAS 78:3363.

I have never heard of the other one.
