Molecular structure of lantadene <jats:italic>C<\/jats:italic> has been deduced from single crystal X\u2010ray diffraction analysis. It resembles lantadene A in the pentacyclic portion of the molecule but differs in the side chain region. Atom C\u201034 <jats:italic>is cis<\/jats:italic> to C\u201035 in lantadene <jats:italic>C<\/jats:italic> but is <jats:italic>trans<\/jats:italic>in lantadene A. Semisynthetic lantadene <jats:italic>C<\/jats:italic> was prepared by catalytic hydrogenation of lantadene A. Lantadene <jats:italic>C<\/jats:italic> was obtained in two forms, I and II. Form I was crystalline while form II was amorphous. Unlike lantadene A, both form I and II of lantadene <jats:italic>C<\/jats:italic> elicited strong hepatotoxic response in guinea pigs associated with decrease in fecal output, feed intake, hepatomegaly, hepatic injury at the cellular and subcellular level, increase in plasma bilirubin, and acid phosphatase activity. All the clinical signs, hepatic lesions, and changes in blood plasma typified lantana toxicity. This is the first report on the hepatotoxicity of lantadene C. The interrelation of molecular structure and biological activity of lantadene A and C has been discussed.<\/jats:p>","DOI":"10.1002\/jbt.2570070204","type":"journal-article","created":{"date-parts":[[2006,10,18]],"date-time":"2006-10-18T01:47:29Z","timestamp":1161136049000},"page":"73-79","source":"Crossref","is-referenced-by-count":16,"title":["Biological action of lantadene C, a new hepatotoxicant from <i>Lantana camara var. aculeata<\/i>"],"prefix":"10.1002","volume":"7","author":[{"given":"Om P.","family":"Sharma","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jagdish","family":"Vaid","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vasantha","family":"Pattabhi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kamlesh K.","family":"Bhutani","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2006,6,8]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/0041-0101(80)90058-6"},{"key":"e_1_2_1_3_2","first-page":"1","article-title":"An outbreak of lantana poisoning in domesticated animals","volume":"2","author":"Yadava J.
