  7-Hydroxycoumarins Are Affinity-Based Fluorescent Probes for Competitive Binding Studies of Macrophage Migration Inhibitory Factor

  摘要：

  Macrophage migration inhibitory factor (MIF) is a cytokine with key roles in inflammation and cancer, which qualifies it as a potential drug target. Apart from its cytokine activity, MIF also harbors enzyme activity for keto-enol tautomerization. MIF enzymatic activity has been used for identification of MIF binding molecules that also interfere with its biological activity. However, MIF tautomerase activity assays are troubled by irregularities, thus creating a need for alternative methods. In this study, we identified a 7-hydroxycoumarin fluorophore with high affinity for the MIF tautomerase active site (Ki = 18 ± 1 nM) that binds with concomitant quenching of its fluorescence. This property enabled development of a novel competition-based assay format to quantify MIF binding. We also demonstrated that the 7-hydroxycoumarin fluorophore interfered with the MIF-CD74 interaction and inhibited proliferation of A549 cells. Thus, we provide a high-affinity MIF binder as a novel tool to advance MIF-oriented research.

  The invention provides a compound having a 12-lipoxygenase inhibitory effect and a drug selectively inhibiting 12-lipoxygenase and relates to a novel coumarin derivative represented by general formula (1) and a drug comprising said compound as the active ingredient. In formula (1) R¹ represents hydrogen or lower alkyl; R² and R³ represent each hydrogen or hydroxyl provided that R² and R³ do not represent hydrogen atoms at the same time; and Ar represents (a) (b), (c) etc.; and R⁴ represents lower alkyl, lower alkoxy, halogen, trifluoromethyl or cyano. It further provides a compound which can be converted into another compound capable of selectively inhibiting 12-lipoxygenase activity through cleavage and breakage of its modifying moiety in vivo and a drug which selectively inhibits 12-lipoxygenase and relates to a novel coumarin derivative having an acyl group as the modifying moiety and a drug containing said compound as the active ingredient. The invention compound, which can potently inhibit 12-lipoxygenase at a high selectivity, is useful as a drug for preventing and treating circulatory diseases such as arteriosclerosis and vasoconstriction and preventing the metastasis of certain cancers. It has a low toxicity and little exhibits side effects.
