Their structures were elucidated by interpretation of 1D and 2D NMR spectra and HRESIMS data. All compounds were evaluated for their cytotoxicity against KB cells and their antiplasmodial activity. Netamine M (<b>6</b>) was found to be cytotoxic, with an IC<sub>50</sub> value in the micromolar range, and netamine K (<b>4</b>) exhibited activity against <i>Plasmodium falciparum</i> with an IC<sub>50</sub> value of 2.4 μM.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Netamines H-N, tricyclic alkaloids from the marine sponge <i>Biemna laboutei</i> and their antimalarial activity","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-28 01:31:48.836454","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2014,"MonPub":null,"DateUpdate":"2020-06-30","DateCreate":"2015-05-31","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000335127200013","VABBcode":null,"OpenAcc":0,"DOI":"10.1021/np4009283"},"refs":null,"anarec":{"AnaID":247398,"PubliDate":2014,"Pagination":"818-823","XtraPublOfAnaID":null,"ISBN":null,"Volume":"77","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43089,"SerRR":"Journal of Natural Products.
