It remains an active and important area of scientific research (Plotkin et al., Naturwissenschaften (2010) 97:1067–1076).[6] References1. ^1 http://cancerweb.ncl.ac.uk/cgi-bin/omd?xanthopterin {{heterocyclic-stub}}2. ^{{cite web|url=http://medical.merriam-webster.com/medical/xanthopterin |title=Archived copy |accessdate=October 17, 2008 |deadurl=yes |archiveurl=https://web.archive.org/web/20071225204927/http://medical.merriam-webster.com/medical/xanthopterin |archivedate=December 25, 2007 }} 3. ^1 http://content.karger.com/ProdukteDB/produkte.asp?Doi=46271 4. ^{{cite web|url=http://www.wikigenes.org/e/ref/e/8490058.html|title=WikiGenes -|work=WikiGenes - Collaborative Publishing}} 5. ^{{cite web|url=http://www.wikigenes.org/e/ref/e/1481869.html|title=WikiGenes -|work=WikiGenes - Collaborative Publishing}} 6. ^{{Cite news | url = http://news.bbc.co.uk/earth/hi/earth_news/newsid_9254000/9254445.stm | title = Oriental hornets powered by 'solar energy' | first = Matt | last = Walker | publisher = BBC | date=6 December 2010}} 2 : Pteridines|Lactams |
