7-hydroxycoumarinyl-γ-Linolenate is a γ-linolenic acid ester of 7-hydroxycoumarin (umbelliferone) that behaves as a substrate for cPLA2. Hydrolysis of 7-hydroxycoumarinyl-γ-linolenate by phospholipase results in the release of the fluorescent compound 7-hydroxycoumarin which can be monitored spectrophotometrically (excitation at 335 nm, emission at 450 nm).

Anantin binds competitively to the receptor of atrial natriuretic factor (ANF) from bovine adrenal cortex (Kd = 0.6 μM) and acts as natriuretic peptide receptor A antagonist.

Gefitinib analog III(4-((3-Chloro-4-fluorophenyl)amino)-7-methoxyquinazolin-6-yl acetate) has potential anti-inflammatory and anti-tumor activity and can be used to study its interactions and activity in organisms.
