With.
Background technique
Guassin is a kind of natural products with extensive pharmacological activity, and activity includes antitumor, anti-malarial, anti-inflammatory, is killed
Worm etc., but it generally has very strong toxicity.Crow gallbladder pavilion was once used as anti-tumor drug to enter clinical research in guassin, however
One of the reason of internal serious toxicity is its failure.While how improving or keep activity, reducing toxicity is by quassia
Chlorins compound is for clinical key.According to the literature (I.H.Hall, K.H.Lee and etc, J.Pharm.Sci,
1983;72:1282), quassinoids natural products Brusatol can stablize lysosome membrane, reduce the release of hydrolase, to drop
The low damage to surrounding tissue.In rat body on inflammatory model, Brusatol (brusatol) shows very strong anti-inflammatory work
Property, activity is much better than Indomethacin.However, Brusatol has very strong toxicity, limit its application.

Son or group) the nitric oxide donors non-steroid anti-inflammatory drug (NO-NSAID) of generation is coupled with NSAID, it is keeping or is increasing
While NSAID curative effect (such as anti-platelet activity increase), adverse reaction (such as gastrointestinal tract and the heart of NSAID can be substantially reduced
Blood vessel adverse reaction).However NO also has double action, on the one hand appropriate endogenous NO plays the role of inhibiting inflammation in vivo;Separately
INOS(iNOS in one side inflammatory process) activation, inflammation can be further aggravated again by synthesizing excessive NO.
Therefore, NO donor and Brusatol are coupled, obtain nitric oxide donor type derivant, it is artificial it is controllable in vivo
Inflammation initial stage generates a small amount of NO, plays similar endothelium-derived NO and acts on, to inhibit inflammation, so that iNOS be inhibited to over-express.
Persistently the NO of low concentration can also improve survival rate of the cell under the toxic effect of Brusatol simultaneously, play the work for reducing toxicity
With.
Currently, had no in the prior art about to NO donator type Brusatol derivative or its medically acceptable salt,
