Description

Carbapenem compound

1, technical field

The present invention relates to ester, its pharmacy acceptable salt, its isomer, its hydrate of carbapenem compound, its facile hydrolysis, and the hydrate of ester or salt, the preparation method of these compounds, the pharmaceutical composition that contains these compounds, and these compounds are used to prepare the purposes of the medicine that treats and/or prevents infectious diseases, belong to medical technical field.

2, background technology

Carbapenems is the New-type wide-spectrum that grows up the seventies in 20th century, anti-enzyme, efficient β-Nei Xiananleikangshengsu.1976, find first carbapenem antibiotic---sulfomycin, but because poor chemical stability fails to be used for clinical.Afterwards sulfomycin is carried out the chemical structure transformation and produced a series of carbapenem antibiotics.This similar drug that has gone on the market at present has imipenum, panipenem, meropenem, S-4661, biapenem, ertapenem etc.

First listing be imipenum, gram-positive and negative bacterium, aerobic and anerobe all there is very strong activity, stable to various β-Nei Xiananmeis, there is not cross resistance with other microbiotic, but easily by dehydropeptidase of kidney-I (DHP-I) degraded rapidly, must share with dehydropeptidase of kidney inhibitor cilastatin clinically in vivo.

The imipenum meropenem

Discover, introduce 1 Beta-methyl, can strengthen the stability of carbapenem compound DHP-I.1 Beta-methyl carbapenem of first listing is a meropenem, can use separately clinically, need not to share with the dehydropeptidase of kidney inhibitor.

Because antibiotic abuse causes the continuous increase of bacterial drug resistance and the limitation that digestive tube absorbs, the carbapenems of listing clinically can only be as the injection administration at present, clinical availability is not high, and to the anti-microbial activity of MRSA a little less than, can not meet clinical needs.
