Preparation, carbonic anhydrase enzyme inhibition and antioxidant activity of novel 7-amino-3,4-dihydroquinolin-2(1H)-one derivatives incorporating mono or dipeptide moiety

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry, 2020
New dipeptide–dihydroquinolinone derivatives were successfully synthesised by benzotriazole mediated nucleophilic acyl substitution reaction and their structures were elucidated by spectroscopic and analytic techniques. The carbonic anhydrase (CA, EC 4.2.

Enzymatically-stable oxetane-based dipeptide hydrogels [PDF]

open access: yes, 2018
Low molecular weight gelators that are not easily degraded by enzymes have a range of potential applications. Here, we report new Fmoc-protected dipeptides in which the amide carbonyl group has been replaced by an oxetane ring.

Induction and Enhancement of Bacteriocin Production (Review)

open access: yesBiotechnology and Bioengineering, EarlyView.
ABSTRACT Conventionally, bacteriocins are produced by microorganisms on complex substrates, released as semi‐purified preparations or crude fermentates. These bacteriocin‐containing products often exhibit unsatisfactory purity, low active‐substance content, and high production costs, limiting their commercialization and use. This review aims to analyze

Structural compatibility between β‐lactams and substrate binding pockets of IMP‐1 and NDM‐1 determines the substrate spectrum

open access: yesBulletin of the Korean Chemical Society, EarlyView.
Chemical structures of three β‐lactam classes and the substrate‐binding pockets (SBPs) of B1 metallo‐β‐lactamases (MBLs) were compared. Structural compatibility between β‐lactams and MBL SBPs correlates with enzymatic activity, providing insights into the substrate spectrum of MBLs and β‐lactam resistance.

Development and application of a mechanistic model for protein A resolution of a bispecific antibody for process characterization and optimization

open access: yesBiotechnology Progress, EarlyView.
Abstract Regeneron's bispecific technology, based on a fully human IgG antibody construct, consists of two distinct heavy chains and a common light chain co‐expressed in a single cell. The co‐expression of the two distinct heavy chains, one of which contains a dipeptide substitution that ablates Protein A binding, leads to the formation of three ...
