Abstract

The present invention relates to antitumor drug (hydroxyl morpholine) and derivative thereof as well as preparation method and application thereof. The antitumor drug (hydroxyl morpholine) and the derivative thereof have structures shown in general formula I. In the formula I, R1 represents hydroxyl, carbonyl, amide, low-level alkyl, benzyloxy methyl, arakyl or unsaturated alkyl of =CH2 or C2-5; R2 represents tetrazole, halogen atoms, halohydrocarbon, cyanogen, cyanomethy, low-level alkyl, benzyloxy methyl, arakyl or unsaturated alkyl of C2-5; and R3 represents hydroxyl, carbonyl or amide. The antitumor drug(hydroxyl morpholine) and the derivative thereof have more excellent antitumor activity and safety, and can be applied to treating tumors of liver cancer, lung cancer, breast cancer, leukemia, colon cancer, ovarian cancer, gastric cancer, nerve cancer and the like, thereby having wide treatment range; and the antitumor drug (hydroxyl morpholine) and the derivative thereof as an antitumor agent have application values in the medicine filed.

Description

technical field [0001] The invention belongs to the field of medicine, and in particular relates to oxydimorph and derivatives thereof, which inhibit tumor cell growth and exert antitumor effects, as well as their preparation method and application. Background technique [0002] In the anticancer screening of traditional Chinese medicines conducted by Feng Weijian et al., the methanol extract of Stellera chamaejasme L. showed strong anticancer activity (Chinese Journal of Oncology, Volume 17, Issue 1, January 1995). Daphne chamaejasme can be used to treat tumor diseases, and its crude extract is clinically reported to be effective in the treatment of lung cancer and liver cancer. Feng Weijian et al. used mouse leukemia as an active indicator to separate and extract Daphne chamaejasme, and obtained a diterpene active ingredient, of which nidimorphine has a strong anticancer effect, and its structure is: [0003] [0004] Nidimoline showed strong anticancer activity agains...
