Urease assay. When Proteus mirabilis grows in a urea-containing medium it hydrolyses the urea to ammonia and consequently raises the pH of the medium. This production of urease is inhibited by aminoglycoside antibiotics (inhibitors of protein synthesis Chapter 8). In practice, it is difficult to obtain reliable results by this method.

L-Digitoxose (53L) and its 4-(9-acetyl derivative are present in a tetrasaccha-ride glycosidically linked in tetrocarcin A, an antibiotic inhibitor of the anti-poptotic Bcl-2 protein family.123 Other tetrocarcins have been isolated from the culture of Micromonospora chalcea KY 11091.124 From another strain of Micromonospora, analogues of tetrocarcin A, called arisostatins A and B, containing isobutanoyldigitoxose instead of acetyldigitoxose were isolated.125... 

Current commercial inhibitors of /3-lactamases include clavulanic acid (an oxapenam see Table 1), sulbactam, and tazobactam (two penam sulfones see Table 1). They are effective only against the class A serine /3-lactamases and they are administrated in the form of antibiotic/inhibitor combinations <2006BP930> Augmentin (amoxicillin/clavulanic acid), Timentin (ticarcillin/clavulanic acid), Unasyn (ampicillin/Sulbactam), Zosyn (piperacillin/tazobactam). 

Little work has been done on the effect of anabolic inhibitors on cellular heat dissipation probably because there is empirical evidence that anabolic processes do not contribute significantly to it (see p. 312). Loike et al. (1981) found that 0.07 mmol dm-3 cycloheximide, an antibiotic inhibitor of protein synthesis, had no effect in 30 minutes on the heat production of murine macrophages. On the other hand, Krakauer and Krakauer (1976) showed that long-term exposure of lymphocytes from immunized horses to 1 mg dm-3 cycloheximide considerably reduced heat production. This was likely to be due to a secondary effect of the antibiotic arresting catabolism by inhibiting the turnover of short half-life enzymes. 

The three antibiotic inhibitors of translation that will be used in this experiment are chloramphenicol, cycloheximide, and puromycin (Fig. 23-10). Chloramphenicol is specific for prokaryotic ribosomes, blocking the transfer of the peptide on the tRNA at the P site to the amino acid linked to the tRNA at the A site (the peptidyl transfer reaction). Since the source of the ribosomes used in this experiment is wheat germ (eukaryotic), we would predict that chloramphenicol would not have a great effect on translation. The mechanism of cycloheximide-mediated inhibition is the same as that described above for chloramphenicol, except for the fact that it is specific for the 80S eukaryotic ribosome. Puromycin is a more broad translational inhibitor, effective on both eukaryotic and prokaryotic ribosomes. It acts as a substrate analog of aminoacyl tRNA. When it binds at the A site of the ribosome, it induces premature termination of translation (Fig.

The spheres removed from SMPs do not support ATP synthesis but do hydrolyze ATP to ADP and phosphate. Thus, ATP synthesis is carried out by Fq/Fi—ATPase (ATP synthase). The subscript o in Fq indicates that it contains the site at which a potent antibiotic inhibitor, oligomycin, binds and inhibits oxidative phosphorylation. Oligomycin does not bind Fi-ATPase and does not inhibit ATP hydrolysis to ADP and phosphate.

This reaction was first reported by Angeli in 1896. It is the preparation of hydroxamlc acids from aidehyde and benzosulfohydroxamic acid. As an important class of reagents, hydroxamic acids have found a variety type of applications in inorganic, organic and pharmaceutical chemistry, including antibiotics, inhibitors, and strong metal ion-chelators, etc. As of today, many other methods have been developed to prepare different hydroxamic acids...
