Abstract
4-Hydroxyphenylmethylene hydantoin (PMH, 1), isolated from the Red Sea sponge Hemimycale arabica, and delta-tocotrienol (3), isolated from the tocotrienol-rich fraction of palm oil, are important antimetastatic and antiproliferative natural products that proved effective against metastatic prostate and breast cancers, respectively. New fluorescent derivatives of PMH (2) and delta-tocotrienol (4) were synthesized by Steglich esterification. Both 2 and 4 retained good anti-migratory and antiproliferative activities, respectively. Fluorescent analogues 2 and 4 can be used for the identification of molecular targets of 1 and 3 in tumor cell cultures.
