Mechanoresponsive, proteolytically stable and biocompatible supergelators from ultra short enantiomeric peptides with sustained drug release propensity
The selectivehydroxylation of benzene to phenol, without the formation of side products resulting from overoxidation, is catalyzed by cytochrome P450BM3 with the assistance of amino acid derivatives as decoy molecules. The catalytic turnover rate and the total turnover number reached 259 min−1 P450BM3−1 and 40 200 P450BM3−1 when N‐heptyl‐l‐proline modified with l‐phenylalanine (C7‐l‐Pro‐l‐Phe) was

self-assemble into functional structures with applications in the areas of nanotechnology, catalysis or medicinal chemistry. Herein, we report a library of 21 short lipopeptides, together with their supramolecular characterization and antimicrobial activity against both Gram-negative (E. coli) and Gram-positive (S. aureus) strains. This study shows that simple lipoaminoacids self-assemble into micellar
In the stereoselective deacylation of H–[CH2]n-1–CONHCH(CH2Ph)CO2–C6H4NO2-p (n=10 and 16), the bilayer catalytic systems of palmitoyl-l-histidine and double-chain surfactants ([CmH2m+1]2N[CH3]2Br; m=12 and 14) offered the relatively higher enantiomer rate ratios (kcatL⁄kcatD=3.7–5.6) as compared with those (kcatL⁄kcatD=3.5–3.6) obtanined with the comicellar system of palmitoyl-l-histidine and octadecyltrimethylammonium chloride.
g natural product syringolin A, was designed and synthesized to develop analogues that are step economical and synthetically accessible in a practical manner. It was revealed that isosyringolin A exhibited proteasome-inhibitory activity comparable to that of syringolin A and that its derivatization leads to great enhancement in its proteasome inhibitory activity as well as its cytotoxicity against
