Imide and isatin derivatives as β-lactam mimics of β-lactam antibiotics [PDF]
, 2002 Activated γ-lactams, which are derivatives of succinimide, phthalimide and isatin with suitable elements of molecular recognition, have been synthesised as mimics of the ß-lactam antibiotics and their chemical and biological reactivity ...

Spherical and rod shaped protoplasts from β-lactam antibiotic treated cultures of Bacillus subtilis [PDF]
FEMS Microbiology Letters, 1988 Addition of β-lactams to exponentially growing cultures of an autolytically deficient Bacillus subtilis metc3 lyt-2 strain FJ6 caused increase in optical density to stop after 1 h when it had about doubled, and thereafter to remain constant for at least 6 h.

NMR spectrometric assay for determining enzymatic hydrolysis of β-lactam antibiotics with bacteria in aqueous solution [PDF]
FEMS Microbiology Letters, 1984 An application of a nuclear magnetic resonance (NMR) spectrometer for the measurement of β-lactamase activity in clinical material containing bacteria is presented. By means of proton (1H)-NMR, it was easy to measure quantitatively β-lactamase activity in human bacteriuria, without performing any such pretreatment as isolation of bacteria or extraction

The state and consideration for skin test of β-lactam antibiotics in pediatrics
Frontiers in Cellular and Infection Microbiology, 2023 β-lactam antibiotics are the most frequently used drugs and the most common drugs that cause allergic reactions in pediatrics. The occurrence of some allergic reactions can be predicted by skin testing, especially severe adverse reactions such as ...

Initiation of murein biosynthesis inEscherichia colicells treated with β-lactam antibiotics [PDF]
FEMS Microbiology Letters, 1987 The study of the synthesis and accumulation of murein in cells initiating growth in the presence of β-lactam antibiotics indicated: (i) Murein rearrangement contributes substantially to cell enlargement during the first doubling in cell mass; (ii) Penicillin-binding protein 2 has the potential capability to synthesize most, if not all, the new murein ...

β-Lactam vs Non-β-Lactam Antimicrobial Prophylaxis and Surgical Site Infection.
JAMA Netw OpenImportance β-lactam-based surgical antimicrobial prophylaxis (SAP) is the standard for most surgical procedures. Alternatively, and mostly due to allergies, non-β-lactam-based prophylaxis is used.

Allergy, Asthma & Clinical Immunology, 2020 Background Penicillins and other β-lactam antibiotics are the most common elicitors of allergic drug reaction. However, data on the pattern of clinical reaction types elicited by specific β-lactams are scarce and inconsistent.

PREPARATION OF ANTIBACTERIAL BENTONITE β LACTAM ANTIBIOTIC COMPOSITE
EQA, 2018 The adsorption of Doripenem (beta-lactam antibiotic belonging to the subgroup carbapenem) from aqueous solution using bentonite as the adsorbent was studied at various pH of the solution. The doripenem loaded in bentonite which called doripenem-bentonite

The Mechanisms of Catalysis by Metallo β-Lactamases [PDF]
, 2008 Class B β-lactamases or metallo-β-lactamases (MBLs) require zinc ions to catalyse the hydrolysis of β-lactam antibiotics such as penicillins, cephalosporins, carbapenems, and cephamycins.
