REVIEW
Jing-Jing Zhu, Jian-Guo Jiang
Coumarins are fused benzene and pyrone ring systems with a wide spectrum of bioactivities including anti-tumor, anti-inflammation, antiviral and antibacterial effects. In this paper, the current development of coumarins-based drugs is introduced, and their structure-activity relationship is discussed by reviewing the relevant literatures published in the past twenty years. Coumarin molecules can be customized by the target site to prevent systemic side effects by virtue of structural modification. The ortho-phenolic hydroxyl on the benzene ring had remarkable antioxidant and anti-tumor activities...

This study was performed to evaluate the cardioprotective effects of osthole (OST) in a rat model of myocardial ischemia/reperfusion injury (MI/RI) and the underlying mechanism. We exposed rat hearts to left anterior descending coronary artery ligation for 30 min followed by 24 h of reperfusion. The results showed that pretreatment with OST ameliorated MI/RI as evidenced by histopathological examination. Moreover, the terminal deoxynucleotidyl transferase dUTP nick end-labeling assay demonstrated that OST suppressed myocardial apoptosis, which may be related to an increase in the Bcl-2/Bax ratio and inhibition of caspase-3 and caspase-9 activation...

Chromenone-derived natural products include chromones (flavone, isoflavone) and coumarins. Chromenone compounds not only exhibit impressive biological activities, but also are an important resource of experimentally used fluorophores, such as, 7-amino-4-methylcoumarin (AMC). Various chromenone compounds have reported to have weak fluorescence, and this has the potential to interfere with the measurements during AMC fluorogenic assays and result in non-robust assay readouts. Several flavones and isoflavones were found as SIRT1 activators, while fluorogenic sirtuin assays utilized AMC labelled peptides as the substrates...
