Description: <p><b>Auraptene</b> - 7-Geranyloxycoumarin</p>
<p><b>Recommended Abbreviation:</b> AUR</p>
<p><b>Alternative Names:</b> Aurapten, 7-geranyloxycoumarin</p>
<p><b>Type:</b> Natural product / prenylated coumarin / prenyloxycoumarin</p>
<p><b>Source:</b> Auraptene occurs naturally in several Rutaceae plants, including citrus fruits such as bitter orange, grapefruit, lemon, and related species, and has also been isolated from <i>Aegle marmelos</i> and <i>Ferula</i> species.</p>
<p><b>Function:</b> Auraptene exhibits anticancer, chemopreventive, anti-inflammatory, antioxidant, antimicrobial, metabolic, and neuroprotective activities. It modulates signaling pathways involved in proliferation, apoptosis, inflammation, xenobiotic metabolism, oxidative stress, and cellular differentiation.</p>
<p><b>Cancer:</b> Auraptene has demonstrated broad preclinical anticancer and chemopreventive activity. Reported effects include proliferation ↓, tumorigenesis ↓, migration/invasion ↓, cancer stem-like markers ↓, apoptosis ↑, caspase activation ↑, p53/p21 signaling ↑, and anti-apoptotic proteins such as MCL1 and BCL-xL ↓ in selected models. Auraptene can also increase sensitivity to anticancer drugs including cisplatin, paclitaxel, and 5-fluorouracil in experimental systems.</p>
<p><b>Alzheimer's Disease:</b> Auraptene has demonstrated experimental neuroprotective and anti-inflammatory activity relevant to neurodegenerative disease, but direct Alzheimer's disease evidence is less established than its cancer evidence. It is better classified as a potential neuroprotective compound rather than a well-established anti-Alzheimer agent.</p>
