Synthesis and Antiproliferative Activity of Triphenylphosphonium Derivatives of Natural Allylpolyalkoxybenzenes.

ABSTRACT: Derivatives of natural allylpolyalkoxybenzenes conjugated to triphenylphosphonium (TPP) cations by aliphatic linkers of three, six, seven, and eight atoms were synthesized to examine the role of the polyalkoxybenzene pharmacophore, TPP fragment, and linker length in antiproliferative activities. The key synthetic procedures included (i) hydroboration-oxidation of apiol, dillapiol, myristicin, and allyltetramethoxybenzene; (ii) acylation of polyalkoxybenzyl alcohols or amines; and (iii) condensation of polyalkoxybenzaldehydes followed by hydrogenation and cyclopropyl-homoallyl rearrangement. The targeted TPP conjugates as well as the starting allylbenzenes, the corresponding alkylpolyalkoxybenzenes, and the respective alkyl-TPP salts were evaluated for cytotoxicity in a panel of human cance
