摘要:
The invention relates to peptide derivatives that can be used as selective inhibitors of the N-terminal site of human angiotensin-converting enzyme. The derivatives comprise the amino acid sequence with the following formula: -Asp-Phe-&PSgr;(PO2CH2)-Ala-Xaa′- (I) wherein: &PSgr;(PO2CH2) indicates that the peptide bond (CONH) between Phe and Ala has been replaced by the phosphonic bond PO2CH2, and Xaa′ represents an amino acid residue. They can be used in pharmaceutical formulations, particularly to protect haematopoietic strain cells of patients undergoing aggressive chemotherapy or radiotherapy treatment.
摘要:
The invention relates to pseudo-peptides according to the formula: wherein R1 is a group inhibiting an amine function, or an amino acid residue or peptide with an inhibited terminal amino function, R2 represents the lateral chain of a natural or non-natural amino acid, R3 represents: 1) the lateral chain of a natural amino acid except for Gly and Ala, not substituted or substituted by an aryl group, 2) an aralkyl group, or 3) an alkyl group comprising at least 3 carbon atoms, and R4 represents a lateral chain of natural or non-natural amino acid. They are useful as matrix zinc metalloprotease inhibitors, particularly in the treatment of cancer.
摘要:
The present invention relates to a peptide tag which can be used to bind a Technetium (Tc) or Rhenium (Re) radionuclide to a protein of interest which comprises the peptide tag and allows the imaging of such a tagged protein. In particular the present invention relates to a peptide tag which chelates a Tc or Re atom but which does not comprise a Cysteine residue.
