Abstract
Mixed simplified structures containing the paclitaxel and eleutherobin pharmacophore moieties were analyzed using molecular docking techniques and synthesized based on adamantane and 8-oxabicyclo[3.2.1]octane scaffolds. The crucial role of substituents' stereochemistry in biological activity is discussed. At micromolar concentrations the selected analogues interfered with tubulin dynamics in vitro and in a living organism. Furthermore, new compounds were cytotoxic against human tumour cell lines. The simplified eleutherobin analogues may be considered as prototypes of a new class of antitumour agents.
