Pakistamides A and B (1 and 2, respectively), two new sphingolipids, have been isolated from the AcOEt-soluble sub-fraction of the MeOH extract of the whole plant of Abutilon pakistanicum. Their structures were assigned by 1 H and 13C NMR spectra, and by DEPT and COSY, NOESY, HMQC, HMBC, EI-MS, and FAB-MS experiments.

Spiraeamide (1), a new sphingolipid, has been isolated from the ethyl acetate-soluble fraction of the methanolic extract of the whole plant of Spiraea brahuica, along with marrubiin (2), 19-acetylmarrubenol (3), and 6-acetylmarruenol (4). Their structures were elucidated by 1H and 13C NMR spectra, and COSY, NOESY, HMQC, HMBC, EI-MS, and FAB-MS experiments.

Two new long-chain ceramides, trametenamides A (1) and B (2), were isolated from the methanolic extract of the fruiting body of the fungus Trametes menziesii. The structures were elucidated by spectroscopic analyses and chemical transformations, and the absolute stereochemistry of trametenamide B (2) was determined by stereoselective total synthesis of four possible diastereomers. The acetyl derivative of the natural ceramide (1a) and synthetic ceramides (24-27) showed cytotoxicity on the human melanoma cell line SK-MEL-1, which was caused by induction of apoptosis as determined by DNA fragmentation, poly-(ADP-ribose) polymerase cleavage, and procaspase-9 and -8 processing.
