Round 7: Tossup 17

In an unknown mechanism, the release of this compound is induced by berdazimer sodium during treatment for water warts. High eosinophil (“ee-oh-SIH-noh-fil”) count and elevated fractional exhaled levels of this compound are often observed in patients with asthma caused by type 2 inflammation. Drugs that [emphasize] promote the action of this compound function by inhibiting phosphodiesterase (“FOS-foh-dye-ESS-ter-ayz”) type 5, (-5[1])which induces (-5[1])the relaxation of the corpus (*) cavernosum. A group of synthases with neuronal, (10[1])inducible, and endothelial isoforms generate this compound from the oxidation of arginine to citrulline. By preventing cGMP degradation, the drug sildenafil enhances the effects of this compound to treat erectile dysfunction. For 10 points, name this gaseous signaling molecule, a potent vasodilator consisting of one oxygen and nitrogen atom. (10[1])■END■ (10[2]0[1])
