描述 | O-phenanthroline is a non-specific matrix metalloproteinase (MMP) inhibitor. O-phenanthroline reduced the expression of MMP3 and MMP13 mRNA levels during chondrogenic differentiation of human chondrocytes (hChs), as well as after TNFα/IL-1β exposure in an explant model. Interestingly, O-phenanthroline significantly inhibited matrix degradation in a TNFα/IL-1β-dependent model of cartilage degeneration when compared to control and natural hypoxia (2.5% O2 ). Additionally, O-phenanthroline alleviated MMP-induced cartilage degradation without affecting chondrogenesis in the explant culture[2]. The lethal effect could be explained by the kinetics of reaction of o-phenanthroline with intracellular Fe2+, i.e., the mono and bis complexes are more reactive than intracellular Fe2+[3]. H2O2 is able to induce mutation at the HGPRT locus in V79 cells and morphological transformation of C3H/10T1/2 cells. O-Phenanthroline abolishes both effects, indicating that hydroxyl radical is directly involved in mutation and carcinogenesis[4]. |
