Contezolid (MRX-I) has reported phase 1 data [12] and phase III data. [13] In 2021, a new drug summary was published by ADIS Press. [ 14 ] In June 2021, marketing approval was granted by the Chinese National Medical Products Administration (NMPA) for use of oral contezolid in moderate to severe complicated skin and skin structure infections.

The antimicrobial spectrum of an antibiotic can be determined by testing its antimicrobial activity against a wide range of microbes in vitro. Nonetheless, the range of microorganisms which an antibiotic can kill or inhibit in vivo may not always be the same as the antimicrobial spectrum based on data collected in vitro. [2] [5]
[98026-51-8] 2-Oxazolidinone is the parent compound of several protein synthesis inhibitor antibiotics and the Evans chiral auxiliaries for aldol reactions . Cycloserine is an antibiotic based on the 3-isoxazolidone parent.
Oxazolidine is a five-membered heterocycle ringwith the formula (CH 2) 3 (NH)O.The O atom and NH groups are not mutually bonded, in contrast to isoxazolidine. [2] [3] Oxazolidines (emphasis on plural) are derivatives of the parent oxazolidine owing to the presence of substituents on carbon and/or nitrogen.
The oxazolidinone pharmacophore—the chemical "template" essential for antimicrobial activity—consists of a 1,3-oxazolidin-2-one moiety with an aryl group at position 3 and an S-methyl group, with another substituent attached to it, at position 5 (the R-enantiomers of all oxazolidinones are devoid of antibiotic properties). [108]
[1] [9] The results of antimicrobial susceptibility tests performed during a given time period can be compiled, usually in the form of a table, to form an antibiogram. [31] [32] Antibiograms help the clinician to select the best empiric antimicrobial therapy based on the local resistance patterns until the laboratory test results are available ...
Glycopeptide antibiotics are a class of drugs of microbial origin that are composed of glycosylated cyclic or polycyclic nonribosomal peptides.Significant glycopeptide antibiotics include the anti-infective antibiotics vancomycin, teicoplanin, telavancin, ramoplanin, avoparcin and decaplanin, corbomycin, complestatin and the antitumor antibiotic bleomycin.
These have a wide range of effects on membrane permeability, cell wall formation and pheromone actions of target cells. In particular, Bacteriocin AS-48 is a cyclic peptide antibiotic produced by the eubacteria Enterococcus faecalis (Streptococcus faecalis) that shows a broad antimicrobial spectrum against both Gram-positive and Gram-negative ...
