β-Lactam Antibiotics Renaissance.
Since the 1940s β-lactam antibiotics have been used to treat bacterial infections. However, emergence and dissemination of β-lactam resistance has reached the point where many marketed β-lactams no longer are clinically effective. The increasing prevalence of multidrug-resistant bacteria and the progressive withdrawal of pharmaceutical companies from antibiotic research have evoked a strong rea...
متن کاملDegradation of β-lactam antibiotics
Recent developments in the chemistry and biology of βlactam antibiotics which culminated with the introduction of several clinically useful classical and nonclassical β-lactams have been most thrilling and highly rewarding. While this review touches upon the historical development of β-lactams and their reactivity in a nutshell, it provides an overview of various aspects of chemical and enzymat...
متن کاملStudies on monocyclic beta-lactam antibiotics. II. Synthesis and antibacterial activity of 3-acylamino-2-azetidinone-1-oxysulfonic acids.
The synthesis and in vitro antibacterial and beta-lactamase inhibitory activity of the 2-azetidinone-1-oxysulfonic acids having a substituent at C-4 position of the beta-lactam ring are described. The influence of C-4 substituents on the antibacterial activity was examined for the compounds having alpha-ureidoacetyl or alpha-oxyiminoacetyl group as acyl side chain at C-3 position. The antibacte...
متن کاملOccupational allergy to β-lactam antibiotics
Background Contact urticaria in atopic patients was described by Hannuksela [1], among others, in 1980. It generally appears within 30 min of allergen contact and, in the majority of cases, is restricted to the areas of contact; however, local spread and generalized urticaria in the sense of anaphylaxis are seen. Allergic rhinoconjunctivitis and asthma may also subsequently occur [2]. Von Krogh...
متن کاملHeterotropic Effect of β-lactam Antibiotics on Antioxidant Property of Haptoglobin) 2-2(-Hemoglobin Complex
Haptoglobin (Hp) is a mammalian serum glycoprotein showing a genetic polymorphism with three types, 1-1, 2-2 and 1-2. Hp appears to conserve the recycling of heme-iron by forming an essentially irreversible but non-covalent complex with hemoglobin which is released into the plasma by erythrocyte lysis. As an important consequence, Haptoglobin-Hemoglobin complex (Hp-Hb) shows considerable antiox...
