Tridecyloxy- or tetradecyloxy-propane derivatives of the formula: ##STR1## wherein R.sup.1 is tridecyl or tetradecyl, R.sup.2 is hydrogen or --OCH.sub.3, and R.sup.3, R.sup.4 and R.sup.5 independently represent hydrogen or C.sub.1-3 alkyl, or ##STR2## represents cyclic ammonio, and their salts, have inhibitory activity to multiplication of tumor cells and antimicrobial activity.

We report methods for the synthesis of polypeptides that are fully functionalized with desirable phosphorylcholine, PC, groups. Because of the inherent challenges in the direct incorporation of the PC group into alpha-amino acid N-carboxyanhydride (NCA) monomers, we developed a synthetic approach that combined functional NCA polymerization with efficient postpolymerization modification. While poly(L-phosphorylcholine serine) was found to be unstable upon synthesis, we successfully prepared poly(L-phosphorylcholine homoserine) with controlled chain lengths and found these to be water-soluble with disordered chain conformations.

followed by regioselective sulfamate formation of the serinol moiety afforded the desired siladenoserinol A, and benzoyl and desulfamated analogues were also successfully synthesized. Biologicalevaluation showed that the sulfamate is essential for biological activity, and modification of the acyl group on the bicycloketal can improve the inhibitory activity against the p53–Hdm2 interaction.
