TNO211 is a bioactive peptide that functions as a highly soluble fluorogenic substrate for select Matrix Metalloproteinases (MMPs)—specifically MMP-2, 8, 12, 13, and 14. Incorporating a cleavable Gly-Leu bond and an EDANS/DABCYL fluorophore/quencher pair, TNO211 enables sensitive detection of MMP activity through fluorescence assays, with an absorption/emission profile at 340/490 nm. It is particularly effective in analyzing MMPs in culture media from endothelial cells as well as untreated synovial fluid from patients, highlighting its utility in investigations of MMP-associated cellular behaviors, including proliferation, migration (adhesion/dispersion), differentiation, angiogenesis, apoptosis, and host defense.

Communic acid has antibacterial activity, including against mycobacterial. trans-Communic acid has potential to be utilized as anti-wrinkling agents and cosmetic ingredients, as they suppress UVB-induced MMP-1 expression.

Isoliquiritin apioside, isolated from Glycyrrhizae radix rhizome, significantly decreases PMA-induced increases in MMP9 activities and suppresses PMA-induced activation of MAPK and NF-κB. Isoliquiritin apioside auppresseses invasiveness and angiogenesis o

Abietic Acid (Sylvic acid) is the primary component of resin acid isolated from rosin.

TP0556351, a potent and selective inhibitor of matrix metalloproteinase-2 (MMP2), exhibits significant efficacy with an IC50 of 0.2 nM and demonstrates the capability to decrease collagen accumulation in a Bleomycin-induced pulmonary fibrosis mouse model. This compound shows promise as a research tool for idiopathic pulmonary fibrosis (IPF) [1].
