    摘要: A new amino acid derivative, N.sup..alpha. -tert-butoxycarbonyl-N.sup.e -(N-bromoacetyl-.beta.-alanyl)-L-lysine (BBAL), has been synthesized as a reagent to be used in solid-phase peptide synthesis for introducing a side-chain bromoacetyl group at any desired position in a peptide sequence. The bromoacetyl group subsequently serves as a sulfhydryl-selective cross-linking function for the preparation of cyclic peptides, peptide conjugates and polymers. BBAL residues are stable to final HF deprotection/cleavage. BBAL peptides can be directly coupled to other molecules or surfaces which possess free sulfhydryl groups by forming stable thioether linkages. Peptides containing both BBAL and cysteine residues can be self-coupled to produce either cyclic molecules or linear peptide polymers. Such peptide derivatives are useful in preparing potential peptide immunogens, vaccines and therapeutics, and for substances such as peptides linked to polymers, plastics, enamels and ceramics.

    摘要: The present invention is directed to a human serum amyloid P component peptide sequence having 12 ammo acid residues and having the sequence identified as Glu-Lys-Pro-Leu-Gln-Asn-Phe-Thr-Leu-Cys-Phe-Arg. The invention is also directed to fragments of the above peptide. Two fragments useful in the present invention have the sequence Phe-Thr-Leu-Cys-Phe-Arg and Leu-Cys-Phe-Arg. The above peptides are useful for attaching cells to substrates such as ceramics, tissue culture, dishes, polymers or enamels and thus are useful as research tools for studying particular cells. The above peptides are also useful in vivo as artificial organ replacements which attach surrounding natural cells.

    摘要: A method to incorporate bromoacetyl and chloroacetyl moieties on amino groups of synthetic peptides using a standard program with an automated peptide synthesizer has been developed. The bromoacetyl and chloroacetyl-derivatized peptides react well with sulfhydryl-containing proteins and with peptides containing cysteine residues. Autopolymerization or cyclization occurs by reaction of the free sulfhydryl of cysteine in a peptide with the bromoacetyl group (or chloroacetyl group) and reactions can generally be controlled by controlling the concentrations of starting peptide in neutral pH buffers. Analytical methods for evaluating the polymers or cyclized peptides include gel filtration chromatography, reverse phase HPLC, SDS-PAGE and amino acid analysis where the degree of reaction can be evaluated by quantifying the amount of S-carboxymethylcysteine formed after HCl hydrolysis. N-bromoacetyl-derivatized peptides are useful as reagents for potential peptide immunogens, vaccines and therapeutics, and for substances such as peptides linked to polymers, plastics, enamels, and ceramics.
