To evaluate the radical scavenging activity of phenolic-rich fractions of Gardenia jasminoides, we first measured the levels of total polyphenols in hexane, ethyl acetate, and butanol fractions from the extract of G. jasminoides. The ethyl acetate fraction of G. jasminoides extract (GJ-EA) showed high level of phenolics, potent reducing power, and 2,2-diphenyl-1-picrylhydrazyl/2,2'-azino-bis 3-ethylbenzothiazoline-6-sulfonic acid radical scavenging effect. In addition, GJ-EA inhibited the overproduction of nitric oxide in lipopolysaccharide-activated BV-2 microglia. Furthermore, we found that GJ-EA suppressed $H_2O_2$-induced PANC-1 pancreatic cancer cell proliferation in a concentration-dependent manner and also reduced their migratory ability. These results suggest that GJ-EA may be a good source for functional foods with antioxidant and chemo-preventive activities.

Matrix metalloproteinases (MMPs) are zinc-dependent endopeptidases that regulate cell-matrix composition and are also involved in processing various bioactive molecules such as cell-surface receptors, chemokines, and cytokines. Our group recently reported that MMP-3, -8, and -9 are upregulated during microglial activation and play a role as proinflammatory mediators (Lee et al., 2010, 2014). In particular, we demonstrated that MMP-8 has tumor necrosis factor alpha (TNF-${\alpha}$)-converting enzyme (TACE) activity by cleaving the prodomain of TNF-${\alpha}$ and that inhibition of MMP-8 inhibits TACE activity. The present study was undertaken to compare the effect of MMP-8 inhibitor (M8I) with those of inhibitors of other MMPs, such as MMP-3 (NNGH) or MMP-9 (M9I), in their regulation of TNF-${\alpha}$ activity. We found that the MMP inhibitors suppressed TNF-${\alpha}$ secretion from lipopolysaccharide (LPS)-stimulated BV2 microglial cells in an order of efficacy: M8I>NNGH>M9I. In addition, MMP inhibitors suppressed the activity of recombinant TACE protein in the same efficacy order as that of TNF-${\alpha}$ inhibition (M8I>NNGH>M9I), proving a direct correlation between TACE activity and TNF-${\alpha}$ secretion. A subsequent pro-TNF-${\alpha}$ cleavage assay revealed that both MMP-3 and MMP-9 cleave a prodomain of TNF-${\alpha}$, suggesting that MMP-3 and MMP-9 also have TACE activity. However, the number and position of cleavage sites varied between MMP-3, -8, and -9. Collectively, the concurrent inhibition of MMP and TACE by NNGH, M8I, or M9I may contribute to their strong anti-inflammatory and neuroprotective effects.
