Protein assembly directed by synthetic molecular recognition motifs
Ma, Mingming,Bong, Dennis
, p. 7296 - 7299 (2011)
Tris-functionalized cyanuric acid (TCA) and melamine (TM) selectively recognize each other in aqueous solution with 1:1 stoichiometry. We have coupled biotin to TCA and TM to allow pseudo-tetrahedral display of TCA and TM on streptavidin through biotin-ligand binding. Synthetic cyanuric acid/melamine recognition is found to drive selective protein-protein assembly.

Advances in the design of permeable peptides and in the synthesis of large arrays of macrocyclic peptides with diverse amino acids have evolved on parallel but independent tracks. Less precedent combines their respective attributes, thereby limiting the p

The synthesis of 6β-(methylfumaramido) and 6β-chloroacetamido derivatives 1b and 1c of 6β-amino-7,8-didehydromorphinan and the corresponding 14-hydroxy derivatives 1e and 1f are described.The 7,8-dihydro derivatives of these compounds were synthesized in inactive (2b,c,e,f) as well as in tritiated form (3b,c,e,f).

A series of structurally modified Tm3+ DOTAM-alkyl complexes as potential PARACEST MRI contrast agents has been synthesized with the aim to decrease the overall positive charge associated with these molecules and increase their biocompatibility. Two types of structural modification have been performed, an introduction of terminal carboxylate arms to the alkyl side chains and a conjugation of one of the alkyl side chains with aspartic acid. Detailed evaluation of the magnetic resonance imaging chemical exchange contrast associated with the structurally modified contrast agents has been performed. In contrast to the acutely toxic Tm3+ DOTAM-alkyl complexes, the structurally modified compounds were found to be tolerated well during in vivo MRI studies in mice; however, only the aspartic acid modified chelates produced an amide proton-based PARACEST signal.

We report the synthesis of a GDP analogue, SML-8-73-1, and a prodrug derivative, SML-10-70-1, which are selective, direct-acting covalent inhibitors of the K-Ras G12C mutant relative to wild-type Ras. Biochemical and biophysical measurements suggest that modification of K-Ras with SML-8-73-1 renders the protein in an inactive state. These first-in-class covalent K-Ras inhibitors demonstrate that irreversible targeting of the K-Ras guanine-nucleotide binding site is potentially a viable therapeutic strategy for inhibition of Ras signaling. Putting a stop to Ras: Two new selective, direct-acting covalent inhibitors of the K-Ras G12C mutant are reported. Studies suggest that the modification of K-Ras with SML-8-73-1 renders the protein inactive. These novel covalent inhibitors demonstrate that irreversible targeting of the K-Ras guanine-nucleotide binding site is potentially a viable therapeutic strategy for inhibition of Ras signaling.

The development of cruzain inhibitors has been driven by the urgent need to develop novel and more effective drugs for the treatment of Chagas' disease. Herein, we report the lead optimization of a class of noncovalent cruzain inhibitors, starting from an inhibitor previously cocrystallized with the enzyme (Ki = 0.8 μM). With the goal of achieving a better understanding of the structure-activity relationships, we have synthesized and evaluated a series of over 40 analogues, leading to the development of a very promising competitive inhibitor (8r, IC50 = 200 nM, Ki = 82 nM). Investigation of the in vitro trypanocidal activity and preliminary cytotoxicity revealed the potential of the most potent cruzain inhibitors in guiding further medicinal chemistry efforts to develop drug candidates for Chagas' disease.
Synthesis and transport studies of model dipeptides with modified N-terminal amino groups into E. coli K12 mutant strains

experimental part, p. 1959 - 1966 (2010/07/04)
The synthesis of Interminable guanidine derivatives of three dipeptides Ala-Ala, Ala-Leu, Ala-Phe and three dipeptides containing betaine as an N-terminal amino acid: Bet-Ala, Bet-Leu, Bet-He has been carried out. The transport studies of the obtained pseudopeptides and corresponding natural peptides into E. coli Kl2 mutant strains have also been performed. The results indicate that modified dipeptides containing N-terminal guanidine or betaine are not transported into E. coli K12 cells.

Chelated lanthanide ions, especially gadolinium, have found wide use as contrast agents in magnetic resonance imaging. A new paradigm for generating contrast, termed PARACEST, was recently described that requires the slow exchange of water or other exchan
