Abstract A series of sesterterpenoid bioconjugates with phospholipids and polyunsaturated fatty acids PUFAs have been synthesized for biological activity testing as antiproliferative agents in several cancer cell lines. Different substitution analogues of the original lipidic ether edelfosine 1-O-octadecyl-2-O-methyl-rac-glycero-3-phosphocholine are obtained varying the sesterterpenoid in position 1 or 2 of the glycerol or a phosphocholine or PUFA unit in position 3. Simple bioconjugates of sesterterpenoids and eicosapentaenoic acid EPA have been obtained too. All synthetic derivatives were tested against the human tumour cell lines HeLa cervix and MCF-7 breast. Some compounds showed good IC50 0.3 and 0.2 μM values against these cell lines. View Full-Text
