METHODS
(-)-Deltoin 1 and the corresponding isoxazolines and aziridines were characterized by spectroscopic means. The cytotoxic (HTC-116, IGROV-1 and
L-Arginine derived nitric oxide (NO) and its derivatives, such as nitrogen dioxide and peroxynitrite, play a role in inflammation and also possibly in the multistage process of carcinogenesis. Four furanocoumarins and eight chromones isolated from the dried root of Saposhnikovia divaricata (Fang
