5-(3',4'-Dihydroxyphenyl)-γ-valerolactone is an active metabolite of various polyphenols, including (-)-epicatechin and procyanidin .1,2 It is formed from these polyphenols by gut microbiota. 5-(3',4'-Dihydroxyphenyl)-γ-valerolactone is an inhibitor of matrix metalloproteinase-1 (MMP-1) and MMP-2 collagen degradation activity (IC50s = 108 and 106 nM, respectively), MMP-1 and MMP-9 gelatin degradation activity (IC50s = 45.2 and 17.7 nM, respectively), and MMP-2 and MMP-9 elastin degradation activity (IC50s = 61.8 and 89 nM, respectively).3 It also scavenges free radicals in a Trolox equivalent antioxidant capacity (TEAC) assay.1
