The inhibitors of soluble adenylate cyclase 2-OHE, KH7, and bithionol compromise mitochondrial ATP production by distinct mechanisms.

Soluble adenylate cyclase (sAC) is a non-plasma membrane-bound isoform of the adenylate cyclases signaling via the canonical second messenger, 3',5'-cyclic AMP (cAMP). sAC is involved in key physiological processes such as insulin release, sperm motility, and energy metabolism. Thus, sAC has attracted interest as a putative drug target and attempts have been made to develop selective inhibitors.
