摘要:
A series of novel aylantimony derivatives of analogues of demethylcantharimide with the formulae ArnSbL(5-n) and ArnSbL'((5-n))(LH = N-hydroxy-demethyldehydrogencantharimide, L'H = N-hydroxy-demethyleantharimide, n = 3, 4; Ar=C6H5, 4CH(3)C(6)H(4), 3-CH3C6H4, 2-CH3C6H4, 4-ClC6H4, 4-FC6H4) were synthesized and characterized by elemental analysis, IR, 1 H NMR and mass spectroscopy. The crystal structures of (C6H5)(4)SbL, (4-CH3C6H4)(3)SbL2 and (3-CHC6H4)(3)SbL'(2) were determined by X-ray diffraction. The in vitro antitumor activities of all compounds against six cancer cells are reported. (C) 2004 Elsevier B.V. All rights reserved.
