The roots of T. x media Rehd. cv. Hicksii gave three novel analogues of paclitaxel modified at the N-acyl residue (N-debenzoyl-N-alpha-methylbutyryl paclitaxel and N-debenzoyl-N-cinnamoyl paclitaxel, Ib and Ic, respectively) or at the ester group at C-2 (2-debenzoyl-2-tigloyl paclitaxel, Id). Compounds Pb and Id showed reduced cytotoxicity and tubulin binding compared to paclitaxel, while Ic retained substantial activity in these assays.
