Enyzme-responsive polymeric assemblies hold great potential for biomedical applications due to the over-expression of disease-associated enzymes, which can be utilized to activate such systems only in afflicted tissues. Herein we demonstrate that the overall molecularweight of polymeric amphiphiles, which have the same hydrophilic/hydrophobic ratio, can be tuned to create polymericmicelles with an extreme

chemistries, we used mixtures of thiols to prepare degradable PEG-dendron amphiphiles functionalized with two different types of enzymatically cleavable end groups. By tuning the feed ratios of the two thiols, we achieved mixtures of hybrids with statistically different ratios of end groups. Studies of the disassembly of statistically mixed hybrids showed that these amphiphiles have higher degrees of
Tandem reactions of nitriles with 2-aminoethanethiolhydrochloride or amino alcohols in the presence of a catalytic amount of cupric methacrylate (CuII2L4, L = methacrylate) were employed to prepare 2-thiazolines and 2-oxazolines under mild reaction conditions. The synthetic procedure showed high selectivity for the synthesis of mono- and bis-thiazolines and oxazolines, and a variety of 2-thiazolines

Several cysteinyl peptides have been synthesised and shown to be reversible competitive inhibitors of the Bacillus cereus metallo-beta -lactamase. The pH dependence of pK(i) indicates that the thiol anion displaces hydroxide ion from the active site zinc(II). D,D-Peptides bind to the enzyme better than other diastereoisomers, which is compatible with the predicted stereochemistry of the active site. (C) 2001 Elsevier Science Ltd. All rights reserved.
