Novel collagen mimics are disclosed with a tripeptide unit having the formula (Xaa-Yaa-Gly).sub.n, where one of the positions Xaa or Yaa is a bulky, non-electron withdrawing proline derivative. By substituting a proline derivative at either the Xaa or Yaa position in the native collagen helix, the stability of the helix is increased due solely to steric effects relative to prior known collagen-related triple helices. Methods are also disclosed for making the novel collagen mimics.

A thin film that has a flexible polymer layer and a peptide layer. The peptide layer is disposed on the flexible polymer layer and has a peptide selected from HYF, DYF and YFD. The thin film reversibly curves with changes in humidity.

The present invention relates to hydrogels prepared using silylated organic molecules (such as silylated biomolecules), a process for obtaining the same, and uses thereof.

Disclosed are proteasome inhibitors, fibroblast activation protein (FAP)-activated prodrugs of proteasome inhibitors, and pharmaceutically acceptable salts of the inhibitors and prodrugs. Also disclosed are related pharmaceutical compositions, and methods of using the inhibitors and prodrugs and compositions thereof, for example, in treating cancer or other cell proliferative diseases. In vitro and in vivo methods of quantifying the expression of FAP in a biopsy sample and a mammal, respectively, are also disclosed.

Pyrrolidine carboxamido derivatives, optical isomers thereof, and salts thereof that are able to prevent, improve, and/or treat inflammatory conditions, including inflammatory bowel disease, and methods for preparing and using the same are provided.

A piezoelectric transducer is provided herein, comprising a three-dimensional structure made of a plurality of peptides, the peptides being self-assembling and the structure being piezoelectric, wherein at least a portion, or each, of said plurality of peptides comprises peptides of 2 to 10 amino acid residues, provided that the plurality of peptides is not consisted of a plurality of Phe-Phe dipeptides. Further described herein are peptides having an amino acid sequence Hyp-Phe-Phe, Boc-Dip-Dip, (L)Trp-(D)Trp or (D)Trp-(L)Trp, as well as three-dimensional structures comprising such peptides.

The present invention discloses compounds of Formula (I), and pharmaceutically acceptable salts, thereof: ##STR00001##
which inhibit coronavirus replication activity. The invention further relates to pharmaceutical compositions comprising a compound of Formula (I) or a pharmaceutically acceptable slat thereof, and methods of treating or preventing a coronavirus infection in a subject in need thereof, comprising administering to the subject a therapeutically effective amount of a compound of Formula (I) or a pharmaceutically acceptable salt thereof.

The present invention generally relates to compounds that are useful for inhibiting one or more of hepatocyte growth factor activator, matriptase, hepsin, Factor Xa, or thrombin. The present invention also relates to various methods of using the inhibitor compounds including treating a malignancy, a pre-malignant condition, or cancer by administering an effective amount of the inhibitor to a subject in need thereof.

Processes for preparing compounds of Formula (1) and Formula (2) are described, wherein X, Y, Z, R.sub.1-R.sub.7, L and n are defined herein. Intermediates useful in the preparation of the compounds of Formula (1) and Formula (2) are also described. ##STR00001##

Provided is at least one peptide of formula (I) and its use, where formula (I) is as follows: X-(Xaa.sub.1).sub.n-Pro*-(Xaa.sub.2).sub.m-Y (I). In formula (I), n=0 and m=1. At the N terminal end of the peptide, X is selected from H, —CO—R.sub.1 and —SO.sub.2—R.sub.1. At the C terminal end of the peptide, Y is selected from OH, OR.sub.1, NH.sub.2, NHR.sub.1 or NR.sub.1R.sub.2, R.sub.1 and R.sub.2 being independently selected from an alkyle, aryle, aralkyle, alkylaryl, alkoxy and aryloxy group, that can be linear, branched, cyclic, poly-cyclic, non-saturated, hydroxylated, carbonylated, phosphorylated and/or sulphured, with the possibility to have in said group skeleton a O, S and/or N heteroatom. Pro* corresponds to a Proline, an analogue or derivative thereof.
