Functionally Diverse Nylon-3 Copolymers from Readily Accessible β-Lactams.
A new family of β-lactams is described that enables anionic ring-opening polymerization (AROP) to prepare nylon-3 materials bearing diverse appended functionality, including carboxylic acid, thiol, hydroxyl and secondary amine groups. Nylon-3 copolymers generated with the new β-lactams are shown to display distinctive self-assembly behavior and biological properties.
متن کاملSynthetic Approaches toward Monocyclic 3‐Amino‐β‐lactams
Due to the emerging resistance against classical β-lactam-based antibiotics, a growing number of bacterial infections has become harder to treat. This alarming tendency necessitates continued research on novel antibacterial agents. Many classes of β-lactam antibiotics are characterized by the presence of the 3-aminoazetidin-2-one core, which resembles the natural substrate of the target penicil...
متن کاملDe-Escalating Anti-Pseudomonal β-Lactams
Methods We retrospectively included all ICU episodes in Ghent University Hospital during 2013 and 2014 with prescription of meropenem, piperacillin-tazobactam or ceftazidime for at least 48 hours, stratifying between ICU episodes of < and ≥4 days; for outcome analysis, only the first ≥4 days episode per patient was included. Deescalation was defined as a change from meropenem to a non-carbapene...
متن کاملPharmacodynamic optimization of β-lactams in the patient care setting
In order to eradicate an infecting organism, it is necessary to achieve or maintain concentrations of an antibiotic in vivo that exceed the minimum inhibitory concentration (MIC) for the organism. Duration of exposure, or time above MIC, was recognized as being important for beta-lactam antibiotics more than 60 years ago. Continuous infusion regimens are associated with higher clinical response...
متن کاملThe intrinsic resistome of Pseudomonas aeruginosa to β-lactams.
Pseudomonas aeruginosa is a relevant opportunistic pathogen particularly problematic due to its low intrinsic susceptibility to antibiotics. Intrinsic resistance has been traditionally attributed to the low permeability of cellular envelopes together with the presence of chromosomally-encoded detoxification systems such as multidrug efflux pumps or antibiotic inactivating enzymes. However, some...
