Isocombretastatins A are 1,1-diarylethene isomers of combretastatins A. We have synthesized the isomers of combretastatin A-4, deoxycombretastatin A-4, 3-amino-deoxycombretastatin A-4 (AVE-8063), naphthylcombretastatin and the N-methyl- and N-ethyl-5-indolyl analogues of combretastatin A-4. Analogues with a 2,3,4-trimethoxyphenyl ring instead of the(More)
A new family of naphthalenic analogues of phenstatins with modifications on the ketone-bridge has been synthesised. The synthesised compounds have been assayed for tubulin polymerisation inhibitory activity as well as for cytotoxic activity against cancer cell lines. The naphthalene has been confirmed as a good surrogate for the isovanillin moiety(More)
A new family of phenstatin analogues has been synthesized and assayed. This family simultaneously incorporates modifications of the A-ring (replacement of the 3,4,5-trimethoxyphenyl by the 2,3,4-trimethoxyphenyl arrangement), B-ring (N-alkyl-5-indolyl) and conversion of the Oxygen keto group into a substituted nitrogen (oximes, hydrazones, and their(More)
Novel phenstatin analogues with a 2-naphthyl moiety combined with either a 2,3,4- or a 3,4,5-trimethoxyphenyl ring have been synthesized, and their tubulin polymerization inhibiting and cytotoxic activities have been evaluated. The 2-naphthyl ring is a better replacement for the 3-hydroxy-4-methoxyphenyl ring in the phenstatin series than in the(More)
We describe the synthesis and biological evaluation of a series of diarylmethyloxime and diarylmethylhydrazone analogues that contain an indole ring and different modifications on the nitrogen of the bridge. Several compounds showed potent tubulin polymerization inhibitory action as well as cytotoxic activity against cancer cell lines. The(More)
