Solid-phase synthesis of prenylcysteine analogs.

ABSTRACT: Prenylcysteine derivatives are of interest for a variety of different biological reasons, including probing the CaaX protein processing pathway. A solid-phase synthesis protocol for the preparation of prenylcysteines using 2-chlorotrityl chloride resin as a solid support has been developed. A series of novel amide-modified farnesylcysteine analogs were synthesized in both high purity and yield under mild conditions. The farnesylcysteine analogs were evaluated using human isoprenylcysteine carboxyl methyltransferase as a biological target, and several new inhibitors, one with significantly enhanced potency, were identified.

Lipid and sulfur substituted prenylcysteine analogs as human Icmt inhibitors.

Project description:Inhibition of isoprenylcysteine carboxyl methyltransferase (Icmt) offers a promising strategy for K-Ras driven cancers. We describe the synthesis and inhibitory activity of substrate-based analogs derived from several novel scaffolds. Modifications of both the prenyl group and thioether of N-acetyl-S-farnesyl-L-cysteine (AFC), a substrate for human Icmt (hIcmt), have resulted in low micromolar inhibitors of Icmt and have given insights into the nature of the prenyl binding site of hIcmt.

Facile Solid-Phase Synthesis and Assessment of Nucleoside Analogs as Inhibitors of Bacterial UDP-Sugar Processing Enzymes.

Project description:The privileged uptake of nucleosides into cells has generated interest in the development of nucleoside-analog libraries for mining new inhibitors. Of particular interest are applications in the discovery of substrate mimetic inhibitors for the growing number of identified glycan-processing enzymes in bacterial pathogens. However, the high polarity and the need for appropriate protecting group strategies for nucleosides challenges the development of synthetic approaches. Here, we report an accessible, user-friendly synthesis that branches from a common solid phase-immobilized uridinyl-amine intermediate, which can be used as a starting point for diversity-oriented synthesis. We demonstrate the generation of five series of uridinyl nucleoside analogs for investigating inhibitor structure-activity relationships. This library was screened for inhibition of representative enzymes from three functional families including a phosphoglycosyl transferase, a UDP-aminosugar acetyltransferase, and a glycosyltransferase. These candidates were taken from the Gram-negative bacteria Campylobacter concisus and Campylobacter jejuni and the Gram-positive bacterium Clostridium difficile, respectively. Inhibition studies show that specific compound series preferentially inhibit selected enzymes, with IC50 values ranging from 35 ± 7 μM to 174 ± 21 μM. Insights from the screen provide a strong foundation for further structural elaboration, to improve potency, which will be enabled by the same synthetic strategy. The solid-phase strategy was also used to synthesize pseudouridine analogs of lead compounds. Finally, the compounds were found to be nontoxic to mammalian cells, further supporting the opportunities for future development.

Solid phase-assisted synthesis and screening of a small library of N-(4-hydroxyphenyl)retinamide (4-HPR) analogs.

Project description:Using solid phase-assisted synthesis and purification, a 49 member library of analogs of the mammary tumor chemopreventive retinoid N-(4-hydroxyphenyl)retinamide (4-HPR) has been prepared. After prescreening for growth inhibitory activity in human mammary tumor cells (MCF-7) in culture, most of those analogs which showed activity (12 of them) were assayed for apoptosis-inducing activity in the MCF-7 cells. At least 3 of the analogs (13, 24, and 28) showed activity approaching that of 4-HPR.

Design, solid-phase synthesis and evaluation of enterobactin analogs for iron delivery into the human pathogen Campylobacter jejuni.

Project description:The human enteropathogen Campylobacter jejuni, like many bacteria, employs siderophores such as enterobactin for cellular uptake of ferric iron. This transport process has been shown to be essential for virulence and presents an attractive opportunity for further study of the permissiveness of this pathway to small-molecule intervention and as inspiration for the development of synthetic carriers that may effectively transport cargo into Gram-negative bacteria. In this work, we have developed a facile and robust microscale assay to measure growth recovery of C. jejuni NCTC 11168 in liquid culture as a result of ferric iron uptake. In parallel, we have established the solid-phase synthesis of catecholamide compounds modeled on enterobactin fragments. Applying these methodological developments, we show that small synthetic iron chelators of minimal dimensions provide ferric iron to C. jejuni with equal or greater efficiency than enterobactin.

Solid-Phase Synthesis of Megamolecules.

Project description:This paper presents a solid-phase strategy to efficiently assemble multiprotein scaffolds-known as megamolecules-without the need for protecting groups and with precisely defined nanoscale architectures. The megamolecules are assembled through sequential reactions of linkers that present irreversible inhibitors for enzymes and fusion proteins containing the enzyme domains. Here, a fusion protein containing an N-terminal cutinase and a C-terminal SnapTag domain react with an ethyl p-nitrophenyl phosphonate (pNPP) or a chloro-pyrimidine (CP) group, respectively, to give covalent products. By starting with resin beads that are functionalized with benzylguanine, a series of reactions lead to linear, branched, and dendritic structures that are released from the solid support by addition of TEV protease and that have sizes up to approximately 25 nm.

Solid-phase peptide synthesis and solid-phase fragment coupling mediated by isonitriles.

Project description:The synthesis of polypeptides on solid phase via mediation by isonitriles is described. The acyl donor is a thioacid, which presumably reacts with the isonitrile to generate a thio-formimidate carboxylate mixed anhydride intermediate. Applications of this chemistry to reiterative solid-phase peptide synthesis as well as solid-phase fragment coupling are described.

Parallel solid-phase synthesis of diaryltriazoles.

Project description:A series of substituted diaryltriazoles was prepared by a solid-phase-synthesis protocol using a modified Wang resin. The copper(I)- or ruthenium(II)-catalyzed 1,3-cycloaddition on the polymer bead allowed a rapid synthesis of the target compounds in a parallel fashion with in many cases good to excellent yields. Substituted diaryltriazoles resemble a molecular structure similar to established terphenyl-alpha-helix peptide mimics and have therefore the potential to act as selective inhibitors for protein-protein interactions.

Solid Phase Synthesis of Fluorosulfate Containing Macrocycles for Chemoproteomic Workflows

Project description:Macrocyclic peptides are attractive for chemoproteomic applications due to their modular synthesis and potential for high target selectivity. We describe a solid phase synthesis method for the efficient generation of libraries of small macrocycles that contain an electrophile and alkyne handle. The modular synthesis produces libraries that can be directly screened using simple SDS-PAGE readouts and then optimal lead molecules applied to proteomic analysis. We generated a library of 480 macrocyclic peptides containing the weakly reactive fluorosulfate (OSF) electrophile. Initial screening of a subset of the library containing each of the various diversity elements identified initial molecules of interest. The corresponding positional and confirmational isomers were then screened to select molecules that showed specific protein labeling patterns that were dependent on the probe structure. The most promising hits were applied to standard chemoproteomic workflows to identify protein targets. Our results demonstrate the feasibility of rapid, on-resin synthesis of diverse macrocyclic electrophiles to generate new classes of covalent ligands.

Solid phase versus solution phase synthesis of heterocyclic macrocycles.

Project description:Comparing a solution phase route to a solid phase route in the synthesis of the cytotoxic natural product urukthapelstatin A (Ustat A) confirmed that a solid phase method is superior. The solution phase approach was tedious and involved cyclization of a ridged heterocyclic precursor, while solid phase allowed the rapid generation of a flexible linear peptide. Cyclization of the linear peptide was facile and subsequent generation of three oxazoles located within the structure of Ustat A proved relatively straightforward. Given the ease with which the oxazole Ustat A precursor is formed via our solid phase approach, this route is amenable to rapid analog synthesis.
