Geranyl acetate is a monoterpene that has been found in C. sativa with diverse biological activities. It reduces compound action potential (CAP) peak amplitude in isolated frog sciatic nerves (IC50 = 0.51 mM). Geranyl acetate inhibits the radial growth of M. gypsum, T. vercossum, and C. tropicalis on solid media. It is sporicidal against B. subtilis when used at a concentration of 1% in an agar diffusion assay. Geranyl acetate inhibits growth of COLO 205 cells (IC50 = 30 μM) via induction of DNA damage, cell cycle arrest at the G2/M phase, and mitochondrial apoptosis.
