Biological Activity of Eperezolid

DescriptionEperezolid(PNU-100592) is a oxazolidinone antibacterial agent, Eperezolid demonstrated good in vitro inhibitory activity, regardless of methicillin susceptibility for staphylococci(MIC90= 1-4 mg/ml). IC50 value: 1-4 mg/ml (MIC90, staphylococci) [1] Target: Antibiotic Eperezolid binds specifically to the 50S ribosomal subunit of Escherichia coli. The specific binding of eperezolid is dose dependent and is proportional to the ribosome concentrations. Scatchard analysis of the binding data reveals that the dissociation constant (Kd) is about 20 microM. The binding of eperezolid to the ribosome is competitively inhibited by chloramphenicol and lincomycin. However, unlike chloramphenicol and lincomycin, eperezolid does not inhibit the puromycin reaction, indicating that the oxazolidinones have no effect on peptidyl transferase [2]. eperezolid was found to bind only to the 50S subunit, with similar affinity as to the 70S ribosome, and to have no affinity for the 30S subunit [3].

Background on Eperezolid

MIC50: 0.5, 1.0, 2.0, 1.0, 16.0 and 2.0 mg/L for Pcptostreptococcus, Propionibacterium acnes, Ciostridium pefringens, Clostridium dijiicile, Bactrroidesjagilis, and Fusobacterium, respectivley

Anaerobic bacteria are a common cause of serious infections. Anaerobic species which predominate in clinical infections include the Bacteroides fragilis group, Clostridium spp. and Peptostreptococcus spp. The oxazolidinones are a novel class of synthetic antimicrobials inhibiting the initiation of protein synthesis. Two compounds of this class, eperezolid and linezolid have been shown to inhibit Enterococcus faecalis and Enterococcus faecium.

In vitro: Ninety per cent of all tested Propionibacterium acnes (30 strains), PeptostreptococccuJ spp. (50 strains), C. perjringens (50 strains) and C. dficile (50 strains) were inhibited by <2 mg>

In vivo: The in vivo effectiveness of eperezolid and linezolid against one strain each of Enterococcus faecalis and vancomycin-resistant Enterococcus faecium was examined in a rat intraabdominal abscess model. Eperezolid was ineffective at doses of 25 mg/kg of body weight twice daily for the reductions in abscess bacterial density for E. faecalis. Against E. faecium infections, intravenous eperezolid was effective, reducing densities approximately 2 log10 CFU/g [2].

Clinical trials: Oral administration of eperezolid (1 000 mg PO) to healthy volunteers has earlier been reported to yield peak serum concentration of 6.28 mg/L, respectively, while the trough concentration was estimated to be 1.62 mg/L, respectively [3].

Simple method for the assay of eperezolid in brain heart infusion broth by high-performance liquid chromatography.[Pubmed:15193729]

J Pharm Biomed Anal. 2004 Jun 29;35(4):847-51.

A sensitive high-performance liquid chromatography (HPLC) method was developed and validated for quantification of Eperezolid in Brain Heart Infusion (BHI) broth. Linezolid was employed as internal standard and sample deproteinization with methanol was used. Calibration standards ranged from 0.10 to 20 mg/l. Recovery was approximately 100% at the concentrations examined. Eperezolid was stable in the autosampler vial for at least 72 h at ambient temperature and in BHI broth for 72 h at 37 degrees C. The intra- and inter-day accuracy and reproducibility (relative standard deviation, R.S.D.) were less than 12.3%. This assay is rapid and ideal for analysis of a large number of samples.

Synthesis of eperezolid-like molecules and evaluation of their antimicrobial activities.[Pubmed:23342495]

Bioorg Khim. 2012 Sep-Oct;38(5):610-20.

3-Fluoro-4-(4-phenylpiperazin-1-yl)aniline (II) prepared from 3,4-difluoro nitrobenzene was converted to the corresponding Schiff bases (III) and (IV) by treatment with 4-methoxybenzaldehyde and indol-3-carbaldehyde, respectively. Treatment of amine (II) with 4-fluorophenyl isothiocyanate affordedthe corresponding thiourea derivative (V). Compound (V) was converted to thiazolidinone and thiazoline derivatives (VI) and (VII) by cyclocondensation with ethylbromoacetate or 4-chlorophenacylbromide, respectively. The synthesis of carbothioamide derivative (X) was performed starting from compound (II) by three steps. Treatment of compound (X) with sodium hydroxide, sulfuric acid, or chlorophenacyl bromide generated the corresponding 1,2,4-triazole (XI), 1,3,4-thiadiazole (XII), and 1,3-thiazolidinone (XIII) derivatives, respectively. The structural assignments of new compounds were based on their elemental analysis and spectral (IR, 1H-NMR, 13C-NMR, and LC-MS) data. In the antimicrobial activity study all the compounds revealed high anti-Mycobacterium smegmatis activity.

In vitro activity of linezolid and eperezolid, two novel oxazolidinone antimicrobial agents, against anaerobic bacteria.[Pubmed:16887605]

Anaerobe. 1997 Oct;3(5):301-6.

Linezolid (formerly U-100766) and Eperezolid (formerly U-100592) are novel oxazolidinone antimicrobial agents that are active against multi-drug-resistant staphylococci, streptococci, enterococci, corynebacteria, and mycobacteria. Preliminary studies also demonstrated that the compounds inhibited some test strains of anaerobic bacteria. Therefore, we extended the in vitro evaluation of these agents to include a total of 54 different anaerobic species. Minimal inhibitory concentration (MIC) values were determined using a standard agar dilution method for 143 anaerobic bacterial isolates. Eperezolid and linezolid demonstrated potent activity against the anaerobic Gram-positive organisms with most MIC values in the range of 0.25-4 microg/mL. Viridans streptococci demonstrated MICs of 1-2 microg/mL; Peptostreptococcus species and Propionibacterium species were inhibited by Eperezolid, especially for Bacteroides species. Linezolid inhibited most bacteroides in the range of 2-8 microg/mL, while Eperezolid was generally two- to eight-fold less active. Linezolid and Eperezolid both demonstrated potent activity against Fusobacterium species,Mobiluncus species,Prevotella intermedia, and Porphyromonas asaccharolytica (MICs of Eperezolid due to its greater activity against Bacteroides species.

Synthesis and antibacterial activities of eperezolid analogs with glycinyl substitutions.[Pubmed:19544480]

Arch Pharm (Weinheim). 2009 Jul;342(7):377-85.

A series of Eperezolid analogs with glycinyl substitutions were prepared and their antibacterial activities were studied against a panel of susceptible and resistant Gram-positive bacteria. The compounds with N-arylacyl or N-heteroarylacyl glycinyl structural units showed good antibacterial activities. The compounds 11b, 11c, and 11e were twofold more active than linezolid against Staphylococcus epidermidis and Enterococcus faecalis. Several pyridine analogs were also prepared and found to have poor antibacterial activity against most of the tested Gram-positive bacteria, however, one of the compounds 12e showed very high activity against Enterococcus faecalis.
