  • Publication number: 20090298707
    Abstract: In certain embodiments, this invention pertains to the creation of “Sparse Matrix” libraries of compounds. The sparse matrix libraries of this invention typically span an n-dimensional parameter (property) space at extremely sparse intervals and thereby provide a relatively small library of compounds (e.g., a library of about 200 or fewer compounds) that can be used to quickly and efficiently screen the compound parameter space for one or more desired physical, chemical, or biological properties (e.g., binding specificity, binding avidity, ?toxicity, solubility, mobility, cell permeability, serum half-life, biocompatibility, etc.).

  • Publication number: 20090098050
    Abstract: Disclosed herein are a class of compounds comprising peptides of the sequence (X-Y-Z)n, wherein X is an amino acid selected from aspartic acid, glutamic acid, asparagine, alanine and glutamine, and Y and Z are amino acids selected from alanine, serine, threonine, phosphoserine, phosphothreonine, and their derivatives. These compounds have the property of binding tightly and specifically to calcified surfaces, making them useful for a variety of applications including remineralization of tooth and bone surfaces, diagnosis of bone and tooth defects, treatment of bone and tooth defects, and analysis of the presence and location of calcified deposits both in vitro and in vivo and in industrial, synthetic, medical, dental, and research applications where identification, localization, or manipulation of calcification is desirable.

  • Publication number: 20080069782
    Abstract: Methods for selectively manipulating a growth rate of a selected bacterium comprising the step of contacting the selected bacterium with a predetermined amount of a quorum sensing molecule to affect a change in the growth rate of the selected bacterium, wherein the quorum sensing molecule is species specific, and the change in the growth rate is dependent on the amount of quorum sensing molecule in a dose-dependent fashion. Also provided are methods for treating or protecting against bacterial infections by utilizing the dose-dependent response of bacterial quorum sensing systems. The methods can be applied to a wide range of bacteria species including Streptococci, Staphylococci, and Bacilli. Compositions, medicaments and oral formulations for use with the methods are also disclosed.

  • Publication number: 20040052814
    Abstract: Microbial infection may be treated by administration of a fusion protein comprising one or more recognition sequences and at least one antimicrobial peptide. In preferred embodiments, a linker peptide connects the recognition sequence and one or more antimicrobial peptides. The recognition sequence may be an immunoglobulin molecule, or fragment thereof, that specifically binds to a target antigen present on a pathogen. The recognition sequence may also be a non-immunological polypeptide, providing that the polypeptide binds specifically to a particular ligand. In presently preferred embodiments the recognition sequence is monoclonal antibody that binds specifically to S. mutans and the antimicrobial peptides are derivatives of histatin.
