After dopamine binding, the dopamine receptor changes his shape and binds the inactive G protein.The G protein expels its GDP molecule replacing it by GTP. and falls into two pieces. The Galpha subunit binds to and activates the enzyme adenylyl cyclase, which produces then cyclic AMP spreading a signal through the cell.

Fluconazole is an antifungal medication used to treat fungal infections like candidiasis and mycosis. Fluconazole alters the active site of the lanosterol 14 alpha-demethylase preventing the demethylation of lanosterol, an essential step in the biosynthesis of ergosterol. Ergosterol plays an important structural role in the regulation of membrane fluidity and permeability. Source: PDB entry 5esf.
