DRUG-LOADED EMULSION

The present invention relates to a drug-loaded emulsion, comprising a modified hydrophobic excipient having the following formula, a hydrophobic drug and a surfactant: where R is a hydrophobic natural compound or a hydrophobic synthetic compound with one to three hydroxyl groups (n=1-3); and R1 is an α-amino protecting group, and R2 is an amino acid side chain, wherein, when m=0, R is reacted with an amino acid derivative with a protecting group by esterification to form a hydrophobic excipient carrying the amino acid derivative with a protecting group; or when m=1, R is firstly introduced with an amino acid linking arm of different chain lengths (l=1, 2, 4, 6) via an ester group, and then introduced with an amino acid derivative with a protecting group.

Synthesis and structural characterization of the individual diastereoisomers of a cross-stapled alkene-bridged nisin DE-ring mimic

Herein, we describe the synthesis, structural characterization, and synthetic use as an advanced intermediate of a cross-stapled alkene-bridged hexapeptide to mimic the DE-ring of the lantibiotic nisin. The linear precursor was cyclized by ring-closing metathesis to give the correctly folded bicyclic hexapeptide in a single step, and the four individual diastereoisomers were isolated, structurally assigned and characterized by HPLC, NMR and MS, respectively. The bicyclic hexapeptide was used as a versatile advanced synthon and was modified at its C- and N-terminus, among others, with an azide moiety to access a building block suitable for Cu(i)-catalyzed alkyne-azide cycloaddition-based ligation reactions.

Synthesis and evaluation of novel dipeptide-bound 1,2,4-thiadiazoles as irreversible inhibitors of guinea pig liver transglutaminase.

Herein we report the synthesis and evaluation of 14 novel peptides as potential irreversible inactivators of guinea pig liver transglutaminase (TGase). These peptides were designed to resemble Cbz-L-Gln-Gly, known to be a good TGase substrate, and to include a 1,2,4-thiadiazole group. The side chain length of the amino acid residue bearing the inhibitor group was also varied in order to permit investigation of this effect. Their inactivation rate constants were measured using a direct continuous spectrophotometric method and were found to vary between 0.330 to 0.89 microM(-1) min(-1).

9-Fluorenylmethyl Pentafluorophenyl Carbonate as a Useful Reagent for the Preparation of N-9-Fluorenylmethyloxycarbonylamino Acids and their Pentafluorophenyl Esters

9-Fluorenylmethyl pentafluorophenyl carbonate is a useful reagent for the efficient, side reaction-free introduction of N-9-fluorenylmethyloxycarbonyl protecting group into amino acids and for the subsequent preparation of their pentafluorophenyl esters.Some new compounds of both types are described.
