Description
Technical field
The present invention relates to Azithromycin derivative and preparation thereof, relate in particular to 11,12-cyclic carbonate ester-Azithromycin 4 " mephenesin Carbamate derivative, preparation method and pharmaceutical composition thereof.
Background technology
Macrolide antibiotic be a class can be oral, the respiratory tract infection pathogenic bacterium are had a microbiotic of anti-microbial activity.Erythromycin once was used widely as first-generation macrolide antibiotic, yet owing to caused its application to be restricted to the acid medium unstable.The s-generation macrolide antibiotic that with the Azythromycin is representative has solved this problem, and very big improvement is being arranged aspect drug effect and the pharmacokinetics.Azythromycin (9-deoxidation-9a-methyl-9a-azepine-9a-a-homoerythromycin A) is first 15 membered macrolide microbiotic that Bright (U.S. Pat 4,474,768) and Kobrehel (U.S. Pat 4,517,357) etc. find.It is that erythromycin is introduced a nitrogen-atoms through oximate, Beckmann rearrangement on lactonic ring, then the special macrolide antibiotic of a class that obtains through reducing, methylating.Its outstanding feature is: stable to acidic medium, tissue permeability is good, plasma half-life is long, clinical indication is wide, evident in efficacy and untoward reaction is few.Particularly Azythromycin has antimicrobial spectrum widely, has the activity that suppresses multiple gram-positive cocci, mycoplasma, chlamydozoan and legionella pneumophilia, especially some important gram negative bacillis such as hemophilus influenzae etc. are had good antibacterial activity, remedied the deficiency of macrolide antibiotic aspect anti-gram-negative bacteria.But, antibiotic being extensive use of, particularly improper use causes bacterial drug resistance to increase year by year.The direct result that bacterial drug resistance produces is to weaken antibiotic validity, and the limit treatment Scheme Selection has a strong impact on clinical efficacy, even causes the treatment failure.Therefore, drug-resistance of bacteria has become the key issue that presses for solution clinically.
Amino formate compounds is the novel derivative of macrolides of another class of report in 1998.This compounds is 4 of the macrolide cladinose, and " position is introduced the carboxylamine ester side chain and is obtained.Anti-microbial activity is similar with acyl lactone to the ketone lactone, and is not subjected to the influence of the gene kind that resistant organism carries.At present, the carboxylamine ester side chain of different lengths is introduced in the Azithromycin 4 of having reported " carbamate derivatives mainly is at Azithromycin 4 " position, 7 link to each other (world patent WO2004101589, WO2005108413, WO2006050941, WO2006050942, WO2006050943 etc.) of the other end of side chain and Carbostyril derivative.
The structural modification of 11,12 hydroxyls of macrolide also is when previous research focus.The modification of 11,12 hydroxyls not only can stop intramolecular ketal increase stability, but also can strengthen anti-microbial activity.For example, 11, the inside and outside anti-microbial activity of 12-cyclic carbonate ester erythromycin (ECC) (commodity are called Davercin) all is better than erythromycin, antibacterial activity in vitro can compare favourably with erythromycin derivatives of new generation such as Roxithromycin, clarithromycin, dirithromycin, Azythromycins, and interior curative effect and Roxithromycin are suitable.At present, Azythromycin 11, the synthetic of 12-cyclic carbonate ester derivative mainly utilizes diethyl carbonate (ethylenecarbonate) to synthesize (S.Djokic et al.J.Chem.Res. (S) 1988,152).11,12-cyclic carbonate ester-Azythromycin 4 " carboxylamine ester side chain (world patent WO2004101585, WO2004101587, WO2004101589, WO2006050941, WO2006050942, WO2006050943), sulphonate side chain (world patent WO2006050940) or the ether side chain (world patent WO2006050942) of different lengths introduced in the position, and 7 of the other end of side chain and Carbostyril derivative link to each other.
According to known and definite prior art, also do not describe from 11 12-cyclic carbonate ester-Azithromycin 4 up to now and " mephenesin Carbamate derivative, the intermediate product derivative that relates to its preparation and method, relate to itself and the inorganic or pharmaceutically acceptable additive salt of organic acid, relate to the purposes that preparation of drug combination method and pharmaceutical composition are used for the treatment of infectation of bacteria.
