19F-NMR-Based Dual-Site Reporter Assay for the Discovery and Distinction of Catalytic and Allosteric Kinase Inhibitors.

ABSTRACT: In modern kinase drug discovery, allosteric inhibitors have become a focus of attention due to their potential selectivity, but such compounds are difficult to identify. Here we describe an NMR-based competition assay using 19F-containing reporter molecules, which allows for rapid identification and discrimination between ATP-competitive and allosteric kinase inhibitors. We illustrate the principle of such a dual-site competition assay with the example of catalytic and allosteric ABL1 kinase inhibitors. The assay can also be used to identify and characterize mixed binding modes of well-known drugs, as shown for crizotinib and fingolimod.

Catalytic site conformations in human PNP by 19F-NMR and crystallography.

Project description:Purine nucleoside phosphorylase (PNP) is a target for leukemia, gout, and autoimmune disorders. Dynamic motion of catalytic site loops has been implicated in catalysis, but experimental evidence was lacking. We replaced catalytic site groups His257 or His64 with 6-fluoro-tryptophan (6FW) as site-specific NMR probes. Conformational adjustments in the 6FW-His257-helical and His64-6FW-loop regions were characterized in PNP phosphate-bound enzyme and in complexes with catalytic site ligands, including transition state analogs. Chemical shift and line-shape changes associated with these complexes revealed dynamic coexistence of several conformational states in these regions in phosphate-bound enzyme and altered or single conformations in other complexes. These conformations were also characterized by X-ray crystallography. Specific (19)F-Trp labels and X-ray crystallography provide multidimensional characterization of conformational states for free, catalytic, and inhibited complexes of human PNP.

Dual 19F/1H MR gene reporter molecules for in vivo detection of ?-galactosidase.

Project description:Increased emphasis on personalized medicine and novel therapies requires the development of noninvasive strategies for assessing biochemistry in vivo. The detection of enzyme activity and gene expression in vivo is potentially important for the characterization of diseases and gene therapy. Magnetic resonance imaging (MRI) is a particularly promising tool, since it is noninvasive and has no associated radioactivity, yet penetrates deep tissue. We now demonstrate a novel class of dual (1)H/(19)F nuclear magnetic resonance (NMR) lacZ gene reporter molecule to specifically reveal enzyme activity in human tumor xenografts growing in mice. We report the design, synthesis, and characterization of six novel molecules and evaluation of the most effective reporter in mice in vivo. Substrates show a single (19)F NMR signal and exposure to ?-galactosidase induces a large (19)F NMR chemical shift response. In the presence of ferric ions, the liberated aglycone generates intense proton MRI T(2) contrast. The dual modality approach allows both the detection of substrate and the imaging of product enhancing the confidence in enzyme detection.

A Dual Reporter Splicing Assay Using HaloTag-containing Proteins.

Project description:To evaluate the effects of genetic variations on mRNA splicing, we developed a minigene-based splicing assay using reporter genes encoding luciferase and the multifunctional HaloTag protein. In addition to conventional RT-PCR analysis, splicing events can be monitored in this system using two parameters: luciferase activity and signals derived from HaloTag-containing proteins bound to a fluorescent ligand following SDS-PAGE. The luciferase activity reflects the accumulated amounts of successfully spliced HaloTag-luciferase fusion products, whereas the amounts and sizes of HaloTag-containing proteins provide quantitative insights into precursor, correctly spliced, and aberrantly spliced mRNA species. Preliminary experiments confirmed that the dual reporter minigene assay can provide estimates of overall splicing efficiency based on the levels of protein products. We then used the minigene assay to analyze a case of chronic granulomatous disease that was caused by a G>C mutation at position +5 in the 5'-splice donor site of intron 5 of the CYBB gene. We found that the G>C mutation affected CYBB mRNA splicing by changing a delicate balance of splicing efficiencies of introns 4, 5, and 6.

19F NMR studies on ?-butyrobetaine hydroxylase provide mechanistic insights and suggest a dual inhibition mode.

Project description:The final step in the biosynthesis of l-carnitine in humans is catalysed by the 2-oxoglutarate and ferrous iron dependent oxygenase, ?-butyrobetaine hydroxylase (BBOX). 1H and 19F NMR studies inform on the BBOX mechanism including by providing evidence for cooperativity between monomers in substrate/some inhibitor binding. The value of the 19F NMR methods is demonstrated by their use in the design of new BBOX inhibitors.

Discovery of an allosteric site in the caspases.

Project description:Allosteric regulation of proteins by conformational change is a primary means of biological control. Traditionally it has been difficult to identify and characterize novel allosteric sites and ligands that freeze these conformational states. We present a site-directed approach using Tethering for trapping inhibitory small molecules at sites away from the active site by reversible disulfide bond formation. We screened a library of 10,000 thiol-containing compounds against accessible cysteines of two members of the caspase family of proteases, caspase-3 and -7. We discovered a previously unreported and conserved allosteric site in a deep cavity at the dimer interface 14 A from the active site. This site contains a natural cysteine that, when disulfide-bonded with either of two specific compounds, inactivates these proteases. The allosteric site is functionally coupled to the active site, such that binding of the compounds at the allosteric site prevents peptide binding at the active site. The x-ray crystal structures of caspase-7 bound by either compound demonstrates that they inhibit caspase-7 by trapping a zymogen-like conformation. This approach may be useful to identify new allosteric sites from natural or engineered cysteines, to study allosteric transitions in proteins, and to nucleate drug discovery efforts.

A 19F-NMR approach using reporter molecule pairs to assess beta-galactosidase in human xenograft tumors in vivo.

Project description:Gene therapy has emerged as a promising strategy for treatment of various diseases. However, widespread implementation is hampered by difficulties in assessing the success of transfection in the target tissue and the longevity of gene expression. Thus, there is increasing interest in the development of non-invasive in vivo reporter techniques to assay gene expression. We recently demonstrated the ability to detect beta-galactosidase activity in stably transfected human prostate tumor xenografts in mice in vivo using 19F NMR. We now extend the studies to human MCF7 breast cancer cells growing as xenografts in nude mice. Moreover, by using two spectrally resolved reporters (o-fluoro-p-nitrophenyl-beta-D-galactopyranoside and an isomer), two tumors could be interrogated simultaneously revealing lacZ transgene activity in a stably transfected tumor versus no activity in a wild-type tumor. Most significantly, hydrolytic activity observed by 19F NMR corresponded to differential activity in lacZ-expressing tumors.

Two-dimensional 19F-13C correlation NMR for 19F resonance assignment of fluorinated proteins.

Project description:19F solid-state NMR is an excellent approach for measuring long-range distances for structure determination and for studying molecular motion. For multi-fluorinated proteins, assignment of 19F chemical shifts has been traditionally carried out using mutagenesis. Here we show 2D 19F-13C correlation experiments that allow efficient assignment of the 19F chemical shifts. We have compared several rotational-echo double-resonance-based pulse sequences and 19F-13C cross polarization (CP) for 2D 19F-13C correlation. We found that direct transferred-echo double-resonance (TEDOR) transfer from 19F to 13C and vice versa outperforms out-and-back coherence transfer schemes. 19F detection gives twofold higher sensitivity over 13C detection for the 2D correlation experiment. At MAS frequencies of 25-35 kHz, double-quantum 19F-13C CP has higher coherence transfer efficiencies than zero-quantum CP. The most efficient TEDOR transfer experiment has higher sensitivity than the most efficient double-quantum CP experiment. We demonstrate these 2D 19F-13C correlation experiments on the model compounds t-Boc-4F-phenylalanine and GB1. Application of the 2D 19F-13C TEDOR correlation experiment to the tetrameric influenza BM2 transmembrane peptide shows intermolecular 13C-19F cross peaks that indicate that the BM2 tetramers cluster in the lipid bilayer in an antiparallel fashion. This clustering may be relevant for the virus budding function of this protein.

Fast Magic-Angle-Spinning 19F Spin Exchange NMR for Determining Nanometer 19F-19F Distances in Proteins and Pharmaceutical Compounds.

Project description:Internuclear distances measured using NMR provide crucial constraints of three-dimensional structures but are often restricted to about 5 Å due to the weakness of nuclear-spin dipolar couplings. For studying macromolecular assemblies in biology and materials science, distance constraints beyond 1 nm will be extremely valuable. Here we present an extensive and quantitative analysis of the feasibility of 19F spin exchange NMR for precise and robust measurements of interatomic distances up to 1.6 nm at a magnetic field of 14.1 T, under 20-40 kHz magic-angle spinning (MAS). The measured distances are comparable to those achievable from paramagnetic relaxation enhancement but have higher precision, which is better than ±1 Å for short distances and ±2 Å for long distances. For 19F spins with the same isotropic chemical shift but different anisotropic chemical shifts, intermediate MAS frequencies of 15-25 kHz without 1H irradiation accelerate spin exchange. For spectrally resolved 19F-19F spin exchange, 1H-19F dipolar recoupling significantly speeds up 19F-19F spin exchange. On the basis of data from five fluorinated synthetic, pharmaceutical, and biological compounds, we obtained two general curves for spin exchange between CF groups and between CF3 and CF groups. These curves allow 19F-19F distances to be extracted from the measured spin exchange rates after taking into account 19F chemical shifts. These results demonstrate the robustness of 19F spin exchange NMR for distance measurements in a wide range of biological and chemical systems.

Discovery of a potential allosteric ligand binding site in CDK2.

Project description:Cyclin-dependent kinases (CDKs) are key regulatory enzymes in cell cycle progression and transcription. Aberrant activity of CDKs has been implicated in a number of medical conditions, and numerous small molecule CDK inhibitors have been reported as potential drug leads. However, these inhibitors exclusively bind to the ATP site, which is largely conserved among protein kinases, and clinical trials have not resulted in viable drug candidates, attributed in part to the lack of target selectivity. CDKs are unique among protein kinases, as their functionality strictly depends on association with their partner proteins, the cyclins. In an effort to identify potential target sites for disruption of the CDK-cyclin interaction, we probed the extrinsic fluorophore 8-anilino-1-naphthalene sulfonate (ANS) with human CDK2 and cyclin A using fluorescence spectroscopy and protein crystallography. ANS interacts with free CDK2 in a saturation-dependent manner with an apparent K(d) of 37 μM, and cyclin A displaced ANS from CDK2 with an EC(50) value of 0.6 μM. Co-crystal structures with ANS alone and in ternary complex with ATP site-directed inhibitors revealed two ANS molecules bound adjacent to one another, away from the ATP site, in a large pocket that extends from the DFG region above the C-helix. Binding of ANS is accompanied by substantial structural changes in CDK2, resulting in a C-helix conformation that is incompatible for cyclin A association. These findings indicate the potential of the ANS binding pocket as a new target site for allosteric inhibitors disrupting the interaction of CDKs and cyclins.
