Side Chain Stereoisomeri Sm and Antistaphylococcal Potency
Penicillins may be regarded as acylation products of 6-aminopenicillanic acid (Figure 1). This bicyclic dipeptide results from cyclization of L-Cysteinyl-L-valine (1) and is loosed into the culture medium in good yield when a strain of Penicillium chrysogenurn (W.51.20) is cultured in the absence of side chain precursors suitable for acylation at the 6-amino grouping (2). With the attainment of...
متن کاملIsolation of a Penicillin Acylase Producing E.coli and Kinetic Characterization of the Whole Cell Enzyme Activity
Penicillin acylase (EC 3.5.1.11) has been a target of study for a long time because of its pivotal role in the deacylation of the penicillin into the 6- aminopenicillanic acid (6-APA) and the side-chain organic acids. This property of penicillin acylase has been exploited commercially for large scale production of 6-APA, which is the key intermediate in the manufacture of semi-synthetic penicil...
متن کاملChallenges and advances in computational docking: 2009 in review.
Docking is a computational technique that places a small molecule (ligand) in the binding site of its macromolecular target (receptor) and estimates its binding affinity. This review addresses methodological developments that have occurred in the docking field in 2009, with a particular focus on the more difficult, and sometimes controversial, aspects of this promising computational discipline....
متن کاملChromatography of penicillins, penicilloates, and penicilloylamides on dextran gels.
The factors influencing the chromatographic behavior on dextran gels of penicillins and their derivatives were investigated by comparing elution profiles and partition coefficients (K(D) and K(AV)) of penicillins differing in side-chain structure and among penicillin derivatives of identical side-chain but different nuclear structure. Under the conditions of pH and ionic strength employed (pH 7...
متن کاملStructure-activity relationship of new 2-substituted penem antibiotics.
The antibacterial activities of three new penems with 4-hydroxyprolinamide, 1-prolinamide and N-methyl-N-2-propionamide substituents, respectively, in position 2 and of their stereoisomers were examined against Staphylococcus aureus, Enterococcus faecalis, Enterococcus faecium, Escherichia coli and Pseudomonas aeruginosa. All substitutes conferred a broad antibacterial spectrum on the penem moi...
