A bioactivity-directed fractionation of the dichloromethane extract of P. serotina fruits led to the isolation of ursolic acid and uvaol as the main non-polar vasodilator compounds. These compounds showed significant relaxant effect on rat aortic rings in an endothelium- and concentration-dependent manner, which was inhibited by NG-nitro-l-arginine methyl ester (l-NAME), dl-propargylglycine (PAG) and glibenclamide (Gli). Additionally, both triterpenes increased NO and H2S production in aortic tissue. Molecular docking studies showed that ursolic acid and uvaol are able to bind to endothelial NOS and CSE with high affinity for residues that form the oligomeric interface of both enzymes. These results suggest that the vasodilator effect produced by ursolic acid and uvaol contained in P. serotina fruits, involves activation of the NO\/cGMP and H2S\/KATP channel pathways, possibly through direct activation of NOS and CSE.<\/jats:p>","DOI":"10.3390\/molecules21010078","type":"journal-article","created":{"date-parts":[[2016,1,12]],"date-time":"2016-01-12T10:19:25Z","timestamp":1452593965000},"page":"78","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":41,"title":["Role of Nitric Oxide and Hydrogen Sulfide in the Vasodilator Effect of Ursolic Acid and Uvaol from Black Cherry Prunus serotina Fruits"],"prefix":"10.3390","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8093-7068","authenticated-orcid":false,"given":"Francisco","family":"Luna-V\u00e1zquez","sequence":"first","affiliation":[{"name":"Laboratorio de Investigaci\u00f3n Qu\u00edmica y Farmacol\u00f3gica de Productos Naturales, Facultad de Qu\u00edmica, Universidad Aut\u00f3noma de Quer\u00e9taro, Centro Universitario, Quer\u00e9taro 76010, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C\u00e9sar","family":"Ibarra-Alvarado","sequence":"additional","affiliation":[{"name":"Laboratorio de Investigaci\u00f3n Qu\u00edmica y Farmacol\u00f3gica de Productos Naturales, Facultad de Qu\u00edmica, Universidad Aut\u00f3noma de Quer\u00e9taro, Centro Universitario, Quer\u00e9taro 76010, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alejandra","family":"Rojas-Molina","sequence":"additional","affiliation":[{"name":"Laboratorio de Investigaci\u00f3n Qu\u00edmica y Farmacol\u00f3gica de Productos Naturales, Facultad de Qu\u00edmica, Universidad Aut\u00f3noma de Quer\u00e9taro, Centro Universitario, Quer\u00e9taro 76010, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2869-588X","authenticated-orcid":false,"given":"Antonio","family":"Romo-Mancillas","sequence":"additional","affiliation":[{"name":"Laboratorio de Investigaci\u00f3n Qu\u00edmica y Farmacol\u00f3gica de Productos Naturales, Facultad de Qu\u00edmica, Universidad Aut\u00f3noma de Quer\u00e9taro, Centro Universitario, Quer\u00e9taro 76010, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fabi\u00e1n","family":"L\u00f3pez-Vallejo","sequence":"additional","affiliation":[{"name":"Laboratorio de Investigaci\u00f3n Qu\u00edmica y Farmacol\u00f3gica de Productos Naturales, Facultad de Qu\u00edmica, Universidad Aut\u00f3noma de Quer\u00e9taro, Centro Universitario, Quer\u00e9taro 76010, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mariana","family":"Sol\u00eds-Guti\u00e9rrez","sequence":"additional","affiliation":[{"name":"Laboratorio de Investigaci\u00f3n Qu\u00edmica y Farmacol\u00f3gica de Productos Naturales, Facultad de Qu\u00edmica, Universidad Aut\u00f3noma de Quer\u00e9taro, Centro Universitario, Quer\u00e9taro 76010, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juana","family":"Rojas-Molina","sequence":"additional","affiliation":[{"name":"Laboratorio de Investigaci\u00f3n Qu\u00edmica y Farmacol\u00f3gica de Productos Naturales, Facultad de Qu\u00edmica, Universidad Aut\u00f3noma de Quer\u00e9taro, Centro Universitario, Quer\u00e9taro 76010, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5932-1333","authenticated-orcid":false,"given":"Fausto","family":"Rivero-Cruz","sequence":"additional","affiliation":[{"name":"Departamento de Farmacia, Facultad de Qu\u00edmica, Universidad Nacional Aut\u00f3noma de M\u00e9xico, Ciudad Universitaria s\/n, M\u00e9xico D.F. 04510, Mexico"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2016,1,12]]},"reference":[{"key":"ref_1","first-page":"e6","article-title":"Heart disease and stroke statistics\u20142013 update: A report from the American Heart Association","volume":"127","author":"Go","year":"2013","journal-title":"Circulation"},{"key":"ref_2","unstructured":"WHO World Health Organization.
