| Research Abstract |
A structure-activity relationship studies revealed that hydrophobicity of YO-14 could be responsible for their antiproliferative activity. Thishypothesis has been explored in this project using the somatostatin sequence,X-TyrD-Trp-Y, and peptide synthesis technique: (1) substitution of Tyr produced morehydrophobic YO compounds with higher antiproliferative activity than YO-14;(2) double replacement (X-Tyr-Ile-NH-aphthalene) created a potent and ss -specific DNA polinhibitor; (3)the distribution of YO compounds incorporated fluorescent NBD, demonstrated that an adamantane moiety had an excellent permeability.
