Grossheimin 1 is a polyfunctionalized sesquiterpene, featuring, in addition to the exomethylene-γ-lactone group, also an additional exocyclic double bond, a hydroxyl, and a ketone carbonyl. These functional groups have been modified, generally in an orthogonal way, by arylation of the exomethylene, by the introduction of heteroatoms associated to oxygen-, nitrogen- and phosphorous functionalities, and by acylation. A selection of the analogues was investigated for bioactivity, showing that the introduction of a substituent at C-13 is not detrimental, and can modulate potency independently from retention or reduction of the C-11 – C-13 exomethylene double bond and the effect of this maneuver on Michael reactivity. In vivo experiments of 26 samples made it possible to establish that grossheimin 1 and its five new derivatives have a pronounced antitumor activity against alveolar liver cancer, Pliss lymphosarcoma, Walkers carcinosarcoma, sarcoma 45, M-1 sarcoma, P-388 leukemia.
