Condensation of 2-((Alkylthio)(aryl)methylene)malononitrile with 1,2-Aminothiol as a Novel Bioorthogonal Reaction for Site-Specific Protein Modification and Peptide Cyclization

Site-specific modification of peptides and proteins has wide applications in probing and perturbing biological systems. Herein we report that 1,2-aminothiol can react rapidly, specifically and efficiently with 2-((alkylthio)(aryl)methylene)malononitrile (TAMM) under biocompatible conditions. This reaction undergoes a unique mechanism involving thiol-vinyl sulfide exchange, cyclization, and elimination of dicyanomethanide to form 2-aryl-4,5-dihydrothiazole (ADT) as a stable product. An 1,2-aminothiol functionality can be introduced into a peptide or a protein as an N-terminal cysteine or an unnatural amino acid. The bioorthogonality of this reaction was demonstrated by site-specific labeling of not only synthetic peptides and a purified recombinant protein but also proteins on mammalian cells and phages. Unlike other reagents in bioorthogonal reactions, the chemical and physical properties of TAMM can be easily tuned. TAMM can also be applied to generate phage-based ADT-cyclic peptide libraries without reducing phage infectivity. Using this approach, we identified ADT-cyclic peptides with high affinity to different protein targets, providing valuable tools for biological studies and potential therapeutics. Furthermore, the mild reaction conditions of TAMM condensation warrant its use with other bioorthogonal reactions to simultaneously achieve multiple site-specific modifications.

Identification of imidazo-pyrrolopyridines as novel and potent JAK1 inhibitors

A therapeutic rationale is proposed for the treatment of inflammatory diseases, such as rheumatoid arthritis (RA), by specific targeting of the JAK1 pathway. Examination of the preferred binding conformation of clinically effective, pan-JAK inhibitor 1 led to identification of a novel, tricyclic hinge binding scaffold 3. Exploration of SAR through a series of cycloamino and cycloalkylamino analogues demonstrated this template to be highly tolerant of substitution, with a predisposition to moderate selectivity for the JAK1 isoform over JAK2. This study culminated in the identification of subnanomolar JAK1 inhibitors such as 22 and 49, having excellent cell potency, good rat pharmacokinetic characteristics, and excellent kinase selectivity. Determination of the binding modes of the series in JAK1 and JAK2 by X-ray crystallography supported the design of analogues to enhance affinity and selectivity.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 343788-69-2, help many people in the next few years.343788-69-2

Synthesis of alpha,beta-Unsaturated Carbonyl-Based Compounds, Oxime and Oxime Ether Analogs as Potential Anticancer Agents for Overcoming Cancer Multidrug Resistance by Modulation of Efflux Pumps in Tumor Cells

Sixty-nine novel alpha,beta-unsaturated carbonyl based compounds, including cyclohexanone, tetralone, oxime, and oxime ether analogs, were synthesized. The antiproliferative activity determined by using seven different human cancer cell lines provided a structure-activity relationship. Compound 8ag exhibited high antiproliferative activity against Panc-1, PaCa-2, A-549, and PC-3 cell lines, with IC50 value of 0.02 muM, comparable to the positive control Erlotinib. The ten most active antiproliferative compounds were assessed for mechanistic effects on BRAFV600E, EGFR TK kinases, and tubulin polymerization, and were investigated in vitro to reverse efflux-mediated resistance developed by cancer cells. Compound 8af exhibited the most potent BRAFV600E inhibitory activity with an IC50 value of 0.9 muM. Oxime analog 7o displayed the most potent EGFR TK inhibitory activity with an IC50 of 0.07 muM, which was analogous to the positive control. Some analogs including 7f, 8af, and 8ag showed a dual role as anticancer and MDR reversal agents.

A convenient preparation of diastereomerically pure, diversely substituted piperazine-2,5-diones from n-protected -amino acids

The products of the Ugi reaction of various N-tert-butoxycarbonyl-protected -amino acids, aldehydes, amines and tert-butyl isocyanide, after tert-butoxycarbonyl deprotection, undergo efficient microwave-assisted cyclization in acetic acid to give diastereomerically pure, racemic piperazine-2,5-diones. The formation of a single diastereomer is rationalized via an enolization equilibration process in acetic acid at high temperature which enriches the product mixture in the more stable diastereomer. The relative stereochemistry of the products are confirmed by NOESY experiments and are consistent with molecular mechanics calculations. Georg Thieme Verlag Stuttgart New York.
