title: Melotenine A, a cytotoxic monoterpenoid indole alkaloid from Melodinus tenuicaudatus.
abstract: Melotenine A (1), an unprecedented skeleton with a 6/5/5/6/7 pentacyclic rearranged ring system, was isolated from Melodinus tenuicaudatus. The structure was elucidated by means of spectroscopic methods and further confirmed by the single-crystal X-ray diffraction analysis. A possible biogenesis was also proposed. Melotenine A exhibited potential inhibition against five human cancer cell lines.
