Description
Technical field
The present invention relates to the preparation method of compound, relate in particular to a kind of 4-1H-1,2,3-triazole-beta-lactam derivatives and preparation method thereof.
Background technology
Since nineteen twenty-eight Alexander Fleming discovery penicillin, β-Nei Xiananleikangshengsu has been brought into play very important effect aspect bacterial-infection resisting.But cause bacterium that β-Nei Xiananleikangshengsu has been produced significant resistance owing to be extensive use of microbiotic
[1], the drug effect of beta-lactam antibiotics also presents downward trend gradually, this owing to the β-Nei Xiananmei of evolving out in some bacterial bodies can the catalysis beta-lactam hydrolysis, thereby make it lose drug effect.Therefore, the activity and the selectivity of traditional penicillin medicine molecule can not satisfy present demand, be badly in need of the new β-Nei acid amide class antibiosis of exploitation and usually resist the resistance of bacterium, or the exploitation beta-lactamase inhibitor is to suppress β-Nei Xiananmei to antibiotic hydrolytic action.On the other hand, studies show that monocycle beta-lactam has antibiotic activity in addition, for example, some monocycle beta-lactam molecule derivants (2-azetidinone) are the potential inhibitors of serine protease, they to cause human body chronic tissue and destroy and the human leukocyte elastase of some other disease (human leucocyte elastase HLE) also has immune deficiency individuality (AIDS) to show certain pharmaceutical activity
[2]Trans 2-azetidinones (Ezetimibe,
) also can be used as cholesterol absorption inhibitor (CAI) treatment cardiovascular disorder
[3]The monocycle beta-lactam derivative that the 4-indoles replaces acts on nervus centralis and antiinflammation is arranged
[4]1H-1,2, the 3-triazole class compounds has pharmaceutical activity widely, and it has significant effect at aspect such as antibiotic, antiviral
[5]Therefore, synthetic 4-1H-1,2,3-triazole-beta-lactam derivatives has important practical significance for the new Beta-lactam medicine of exploitation.
