Аннотация:An efficient method for the conversion of available plant allylpolyalkoxybenzenes into unsubstituted and
arylsubstituted polymethoxylated aryldihydrobenzo[g]indazoles, analogues of combretastatin A4, has
been developed. The selective demethylation of target compounds resulted in indazoles with different
position of OH-group. Their structure was confirmed by X-ray analysis. A sea urchin embryo assay
revealed the lack of tubulin-related antimitotic activity of aryldihydrobenzo[g]indazoles with systemic
toxicity of a compound featuring OH group and 1-unsubstituted pyrazole ring.
