The structures of these compounds were determined by spectroscopic methods. Biological activity of the compounds against Leishmania major promastigotes was evaluated. Mixture of the novel chromanones 1 and 2 showed significant growth inhibition of the parasite in the micrograms per milliliter range.<\/jats:p>","DOI":"10.1515\/znc-2007-5-606","type":"journal-article","created":{"date-parts":[[2015,2,4]],"date-time":"2015-02-04T13:04:12Z","timestamp":1423055052000},"page":"353-356","source":"Crossref","is-referenced-by-count":19,"title":["Chromanones with Leishmanicidal Activity from Calea uniflora"],"prefix":"10.1515","volume":"62","author":[{"given":"Andr\u00e9a","family":"Mendes do Nascimento","sequence":"first","affiliation":[{"name":"Departamento de F\u00edsica e Qu\u00edmica, Faculdade de Ci\u00eancias Farmac\u00eauticas de Ribeir\u00e3o Preto, Universidade de S\u00e3o Paulo, Via do Caf\u00e9 s\/n, 14040-903, Ribeir\u00e3o Preto, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fernanda Cristina","family":"Costa","sequence":"additional","affiliation":[{"name":"Instituto de F\u00edsica de S\u00e3o Carlos, Universidade de S\u00e3o Paulo, Avenida Trabalhador S\u00e3ocarlense 400, 13566-590, S\u00e3o Carlos, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Otavio Henrique","family":"Thiemann","sequence":"additional","affiliation":[{"name":"Instituto de F\u00edsica de S\u00e3o Carlos, Universidade de S\u00e3o Paulo, Avenida Trabalhador S\u00e3ocarlense 400, 13566-590, S\u00e3o Carlos, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dion\u00e9ia Camilo","family":"Rodrigues de Oliveira","sequence":"additional","affiliation":[{"name":"Departamento de F\u00edsica e Qu\u00edmica, Faculdade de Ci\u00eancias Farmac\u00eauticas de Ribeir\u00e3o Preto, Universidade de S\u00e3o Paulo, Via do Caf\u00e9 s\/n, 14040-903, Ribeir\u00e3o Preto, SP, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"374","published-online":{"date-parts":[[2014,6,2]]},"container-title":["Zeitschrift f\u00fcr Naturforschung C"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.degruyter.com\/view\/journals\/znc\/62\/5-6\/article-p353.xml","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.degruyter.com\/document\/doi\/10.1515\/znc-2007-5-606\/xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.degruyter.com\/document\/doi\/10.1515\/znc-2007-5-606\/pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,6,22]],"date-time":"2021-06-22T06:16:39Z","timestamp":1624342599000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.degruyter.com\/document\/doi\/10.1515\/znc-2007-5-606\/html"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2007,6,1]]},"references-count":0,"journal-issue":{"issue":"5-6","published-online":{"date-parts":[[2014,6,2]]},"published-print":{"date-parts":[[2007,6,1]]}},"alternative-id":["10.1515\/znc-2007-5-606"],"URL":"https:\/\/doi.org\/10.1515\/znc-2007-5-606","relation":{},"ISSN":["1865-7125","0939-5075"],"issn-type":[{"value":"1865-7125","type":"electronic"},{"value":"0939-5075","type":"print"}],"subject":[],"published":{"date-parts":[[2007,6,1]]}}}
