摘要:
Flurbiprofen analog compounds having an amino acid derivatized at the flurbiprofen alkanoic acid carboxyl group and terminating at an ester or amide group are effective in inhibiting cancer cells in vitro and inhibiting the growth of cancers in viva. The compounds and pharmaceutical compositions containing them are particularly useful for the treatment of lung, pancreatic and head and neck cancers.
摘要:
Disclosed are antimicrobial peptides with useful or superior properties such as antimicrobial activity, desirable levels of hemolysis, and advantageous therapeutic index against various microorganisms, especially Pseudomonas aeruginosa, Acinetobacter baumannii and Staphylococcus aureus. Also provided are methods of to control microbial growth and pharmaceutical compositions to treat or prevent microbial infections. Certain peptides are disclosed utilizing a structure-based rational modification of antimicrobial peptide D1, with single D-/L-amino acid substitutions or charged residue substitutions in or near the center of the peptide on the nonpolar or polar face, or peptides with one or more amino acids in the D configuration, and peptides with all amino acids in the D configuration. Modified peptide analogs herein can demonstrate one or more properties such as improved antimicrobial activity, specificity, and resistance to degradation. Compositions disclosed herein are useful as antibiotics, including as broad spectrum antibiotics.
摘要:
The invention relates to diseases of coronaviruses, particularly severe acute respiratory syndrome (SARS). Compositions and methods in connection with peptide-based compounds are described relating to inhibition or prevention of coronavirus activity including that of SARS coronavirus and the ability of its S protein to achieve fusion with and entry into a target cell.
摘要:
A method of treating Candida albicans infection is disclosed. In one embodiment, for treatment of oral or vaginal infection, the treatment is by topical application of a composition of conjugates that are each composed of a carrier structure and multiple .beta.GalNac(1-4).beta.Gal moieties attached to the structure. In another embodiment, for treatment of systemic infection, the treatment is by parenteral administration of a humanized form of a mouse monoclonal antibody produced by mouse hybridoma cell line Fm16 or cell line PK99H.
摘要:
A peptide having a sequence corresponding to a C-terminal portion of the Pseudomonas aeruginosa pilin protein is disclosed. The peptide is cross-reactive with surface peptides present in certain bacterial and fungal microorganisms, and is effective in inhibiting binding of such organisms to target epithelial cells. The peptide may also be employed in a vaccine composition, for producing immunity against such cross-reactive microorganisms. Also disclosed are methods of preparing peptides which are cross-reactive with the P. aeruginosa pilin peptide, and chimeric monoclonal antibodies immunoreactive with the pilin peptide.
摘要:
Templated conjugates created from naturally-occurring protein sequences found in pathogens, such as viruses, are disclosed. The sequences are “templated” into a consensus coiled-coil sequence in a platform in order to form a two-stranded antigen suitable for immunization of a subject.
摘要:
The invention relates to the use of constrained coiled-coil polypeptides to mimic α-helical structural elements of native proteins. These constrained peptidyl mimetics are used to generate and/or identify ligands which selectively bind the α-helical segment contained in the native protein.

摘要:
Treatment and diagnosis of P. aeruginosa infection or colonization is achieved in accordance with this invention by the discovery of a polypeptide which is smaller than the naturally occurring P. aeruginosa pillin protein. The pure polypeptide comprises at least one amino acid residue sequence containing about twelve amino acid residues and up to about twenty amino acid residues that define a sequence capable of immunologically mimicking an antigenic determinant cite of P. aeruginosa pilin. This amino acid residue sequence can repeat as a unit one or more times in the same polypeptide molecule. More than one of such repeating units and more than one repeating unit of the same type can be present in a single polypeptide molecule. The polypeptides act an antigens or immunogens and antibodies may be raised to the immunogens and a vaccine prepared suitable for the prevention of P. aeruginosa infection.
摘要:
A peptide having a sequence corresponding to an antigenic site in the protein exoenzyme S which is antigenically similar to a C-terminal portion of the Pseusdomonas aeruginosa pilin protein is disclosed. The peptide is cross-reactive with surface peptides present in certain bacterial and fungal microorganisms, and is effective in inhibiting binding of such organisms to target epithelial cells. The peptide may also be employed in a vaccine composition, for producing immunity against such cross-reactive microorganisms.
