Abstract

The invention relates to the field of pharmaceutical chemistry, and discloses nitric oxide donor tamibarotene derivatives and their preparation method and use. Specially, the invention provides nitric oxide donor tamibarotene derivatives shown in the structural general formula (I), wherein a definition of R is shown in the patent specification. The nitric oxide donor tamibarotene derivatives are a type of multi-target compounds prepared from Furoxan type nitric oxide donors and a retinoic acid receptor (RAR) agonist through heterozygosis of ester bonds or amide bonds of various connecting groups. The nitric oxide donor tamibarotene derivatives are suitable for being utilized as anti-tumor drugs for treating all types of leukemia.

Description

technical field [0001] The present invention relates to the field of medicinal chemistry, in particular to nitric oxide donating type tamibarotene derivatives and a preparation method thereof, as well as the medical application of these compounds, especially the application as anti-leukemia drugs. Background technique [0002] Nitric oxide (NO) is an important cell messenger molecule that widely exists in various organisms. As a messenger molecule, it can freely pass through the biomembrane and transmit information between cells. The endogenous NO in the body is produced by Molecular oxygen is generated by oxidizing the guanidine N atom at the end of L-Arg under the catalysis of nitric oxide synthase (NOS). NO is widely involved in the regulation of many physiological processes in the body, and plays an important biological role in the immune system, nervous system, and cardiovascular system. Especially in the immune system, NO plays an extremely important role as a key eff...
