Abstract

The invention discloses hydrogenated cortisone derivant from NO as compound I in the medical chemical domain, which reserves or reinforces anti-inflammatory action and lessens the bad reaction of elevation of blood pressure and osteoporosis.

Description

technical field [0001] The invention relates to the field of pharmaceutical compounds, in particular to a NO donor hydrocortisone derivative. The invention also discloses a preparation method of the derivative and its use as an anti-inflammatory drug. Background technique [0002] Hydrocortisone is widely used clinically because of its powerful pharmacological effects, but long-term medication can cause many adverse reactions such as hypertension and osteoporosis. [0003] Nitric oxide (NO) participates in the regulation of many physiological functions in the body, and is closely related to the cardiovascular system, nervous system, immune system, bone metabolism system, etc. It is a small molecule compound that has been studied in depth. In recent years, NO-donating drugs have developed significantly in both basic and applied research. NO is linked to certain drugs, which can enhance drug efficacy and / or reduce toxic side effects. Contents of the invention [0004] The ...
