Description: ANTITUMORA COMPOUNDS The present invention relates to new antitumoral derivatives of spisulosine-285. BACKGROUND OF THE INVENTION Spisulosine 285 is a bioactive compound that has been found to possess specific antitumor activity, described in the International Patent WO 99/52521. In the same patent specification are also described sphingoid- type bases spisulosines 299 and 313 and some sphingosine analogs. 1 (spisulosine-285) n = 14 2 (spisulosine-299) n = 15 3 (spisulosine-313) n = 16 sphingosine, n=12 and nonadeca-4-sphingenine, n=13; and sphinga-4,10-diene. Spisulosines 285, 299 and 313 were isolated from Spisula polynyma, an edible clam originally isolated from samples found off the coast of Japan.

Values are Molar NA = not active EXPERIMENTAL SECTION General Procedures All solvents were reagent grade (used in work-ups) or HPLC grade (used as reaction and/ or as purification solvent). Anhydrous solvents were used directly as supplied by the manufacturer. All other reagents were commercial compounds of the highest purity available. All amino acids and their derivatives used as starting materials were commercially available. Compounds 1 and 39 were described in the International Patent WO 99/52521. Analytical thin-layer chromatography (TLC) was performed on Merck silica gel aluminium sheets (60, F254) precoated with a fluorescent indicator. Visualization was effected using ultraviolet light (254 nm), phosphomolybdic acid (7% w/v) in 95% ethanol. Proton and carbon magnetic resonance spectra ( l H, 13 C-NMR) were recorded on a Varian-300 (300 MHz) Fourier transform spectrometer, and chemical shifts were expressed in parts per million (ppm) relative to CHCb as an internal reference (7.26 ppm for X H and 77.0 for 13 C). Multiplicities are designated as singlet (s), doublet (d), doublet of doublets (dd), doublet of triplets (dt), triplet (t), quartet (q), quintet (quint), multiplet (m), and broad singlet (br s). Electrospray ionization mass spectra (ESI-MS) were obtained on a Hewlett Packard Series 1100 MSD. Flash column chromatography was carried out on E. Merck silica gel 60 (240-400 mesh) using the solvent systems listed under individual experiments.
