5-ROX, a rhodamine dye, exhibits strong fluorescence property in aqueous buffer with the λexit of 580 nm (ε=3.6×10^4/(M·cm)), and λemit of 604 nm (?=0.94).

Terrestrosin D can induce apoptotic cell death and inhibit angiogenesis in xenograft tumor cells, cell cycle arrest and induction of apoptosis in cancer cells and endothelial cells might be plausible mechanisms of actions for the observed antitumor and antiangiogenic activities of terrestrosin D.

Phenylpropiolic acid is an endogenous metabolite.
