Synthesis and biological evaluation of oxadiazole derivatives as inhibitors of soluble guanylyl cyclase.
Bioorg. Med. Chem. 18(3) , 1288-96, (2010) Soluble guanylyl cyclase (sGC) is an ubiquitously expressed enzyme that generates the second messenger cGMP and hence, leads to a number of physiological responses including vasodilation, inhibition o... |
