摘要:
The present invention relates to p21 derived peptides capable of inhibiting CDK/cyclin complexes, particularly cyclins A or E/CDK2, by modifying the interaction with their substrates. The peptides are derived from a C-terminal region of p21 and display selectivity for cyclin/CDK2 inhibition over cyclin/CDK4 inhibition. Variants of such peptides particularly involving certain alanine replacements are shown to be particularly potent.
摘要:
Structural and functional analysis of peptide inhibitor binding to the cyclin D1 groove has been investigated and used to design peptides that provide the basis for structure-activity relationships, have improved binding and have potential for development as chemical biology probes, as potential diagnostics and as therapeutics in the treatment of proliferative diseases including cancer and inflammation.
摘要:
Methods for developing non-peptidic inhibitors that target the polo-box domain of PLK1 proteins are described. Methods include developing structure activity relationships for peptidic inhibitors followed by development of non-peptide fragment alternatives for portions of the peptide inhibitors. The non-peptide fragment can provide similar structure activity relationship as the replaced peptide. Fragment alternatives to key binding determinants are identified in an iterative computational and synthetic process facilitated through understanding of the peptide structure-activity relationships. The approach is informed by peptide structure-activity data obtained through synthesis and testing of truncated and mutated analogs of known PBD binding motifs.
