| Outline of Final Research Achievements |
GGCT (gamma-glutamylcyclotransferase) is known to be one of cancer-promoting proteins. In this study we planned developing the low molecular compounds that can inhibit GGCT function in cancer proliferation. Among the 40 compounds we designed, GA (N-glutaryl-L-alanine) showed the highest GGCT inhibition efficiency. However, since GA had low cell membrane permeability, the diesterified compound, pro-GA, was designed for the purpose of enhancing membrane permeability.
Pro-GA showed a significant inhibition on cell growth in MCF7 breast cancer cell, PC3 prostate cancer cell and HL-60 leukemia cell. Intraperitoneal administration of pro-GA showed a significant tumor growth inhibition in MCF7- and PC3-inoculated mice. Body weight loss and treatment-related death were not observed in these xenograft mice.
