Colorectal cancer is the fourth most common cancer diagnosis per year as well as the fourth highest rate of death per year according to the Centers for Disease Control. Approximately 1/3rd of the diagnosed colorectal cancer cases per year will result in death. Prior research from our group has shown that the prostaglandin-ethanolamide 15-deoxy, Δ12,14 prostamide J2 (15d-Δ12,14-PMJ2) is selectively toxic to murine melanoma cells (B16F10) and murine colorectal cells (CT-26) both in vitro and in vivo and significantly reduces tumor growth. Further, 15d-Δ12,14-PMJ2 induces cell death in primary patient melanoma cells and thus may be a promising therapeutic. As 15d-Δ12,14-PMJ2 can be made by the condensation of ethanolamine with 15-deoxy, Δ12,14 prostaglandin J2 (15d-Δ12,14-PGJ2), we sought to test the cytotoxicity of other prostamide derivatives to determine the structural features required for activity. Based on prior results in a study of related prodrugs, 15d-Δ12,14-PMJ2-Arvanil was selected as the top candidate for testing anti-cancer activity. After testing in both a human and murine cell line, it was determined that 15d-Δ12,14-PMJ2-Arvanil was not as cytotoxic as 15d-Δ12,14-PMJ2. It is possible that the bulkier functional group on the α-chain of the prostamide prevents transport into the cell the same way or to the same degree 15d-Δ12,14-PMJ2 enters. In an effort to test this hypothesis, and to develop an improved means for systemic delivery for this class of hydrophobic prostamides, engineered micelles composed of 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[methoxy(polyethylene glycol)-2000] and D-α-tocopherol polyethylene glycol 1000 succinate were investigated as drug carriers.
