The effect of structuralvariations on the rates of elastase-catalyzed hydrolysis of model carbonate and carbamateesters was studied using HPLC. It is shown that branching in the immediate vicinity of the carbonate or carbamate functionally results in decreased hydrolysisrates. Whereas aryl carbonates act as substrates for elastase, p-nitrophenyl butyl carbamate inhibits the enzyme. A novel method

The invention relates to novel pyrido[2,3-b]pyrazine derivatives of the general formulae (I) and (II), and to their preparation and use as medicaments, especially for the treatment of malignant disorders and other disorders based on pathological cell proliferations.
Disclosed is a novel carbapenem derivative having a substituted imidazo[5,1-b]thiazole group at the 2-position on the, carbapenem ring have high anti-microbial activities against &bgr;-lactamase producing bacteria, MRSA, resistant-
Pseudomonas aeruginosa
, PRSP, enterococci, and influenza, and high stabilities to DHP-1. According to the present invention, there is provided a compound represented by the formula (I), or a pharmacologically acceptable salt thereof or an ester at the 3-position on the carbapenem ring thereof:
