Structure-activity relationship in PAF-acether. 3. Hydrophobic contribution to agonistic activity
摘要:
The synthesis of some selected PAF-acether homologues with an alkoxy-chain length from C1 to C20 in position 1 is described. All agonist activities are closely correlated among themselves and with the calculated fatty-chain hydrophobicity. After a discussion on recent published results and comparison with our data, we conclude that the ether oxide function is absolutely essential at the glycerol 1-position for potent agonist activity and that potency correlates well with hydrophobicity parameters. We indicate the importance of steric and configurational constraints.

Two series of erlotinib-alkylphospholipid hybrids were prepared and evaluated for their antiproliferative activities against a panel of four cell lines representing lung, breast, liver and skin cancers using erlotinib and miltefosine as reference standards. Amide analogs elicited more enhanced cytotoxic activity than analogous esters. Amide derivatives 8d and 8e exhibited promising broad-spectrum antiproliferative
