摘要:
Novel compounds of formula (I), in which R is a hydroxy, alkyloxy, phenylalkyloxy radical or -NH-CH2-COOH, R' and R'' are the same and are each a hydroxy or methoxy radical and R''' is a hydrogen, bromine, chlorine or iodine atom or a nitro radical. The invention also concerns the salts of said compounds and their use.
摘要:
A thio-selective radioactive labeling agent has the following general formula: *R-L-VS, wherein said *R is a radioisotope, L is a linking group, and VS is a vinylsulfone functional group.
摘要:
A thio-selective radioactive labeling agent has the following general formula: *R-L-VS, wherein said *R is a radioisotope, L is a linking group, and VS is a vinylsulfone functional group, wherein said labeling agent is capable of covalently bonding to thiol containing biomolecules such as proteins or peptides. Use of said labeling agents for labeling neurotensin and its variants are also disclosed.
摘要:
Neuropeptide analogs and compositions including neuropeptide analogs are described herein. Also provided are methods of producing and using the neuropeptide analogs and compositions including one or more neuropeptide analogs.
摘要:
This invention relates to non-natural desamino alkyl amino acid compounds, methods of making, and peptides containing these compounds as their N-terminus moieties. A preferred example is neurotensin (8-13) in which the N terminus is an alpha desamino, alpha methyl N,N dimethyl homolysine residue.
摘要:
The present invention relates to a family of peptides encoding antagonists of the vasoactive intestinal peptide (VIP) of formula (I) designed to distinguish multiple receptors that mediate VIP neurotransmission, neurotrophism and cell division. The invention also relates to methods of using these peptides to antagonize VIP-associated activity and function. The invention further relates to pharmaceutical compositions designed to inhibit VIP-associated activity. In formula (I), R and R are members independently selected from the group consisting of hydrogen, C1 to C20 alkyl and C1 to C20 acyl, provided that at least one of R or R is hydrogen; and X and X are members independently selected from the group consisting of naturally occurring amino acids and amino acid mimetics.
