Abstract
Spatiotemporal control of chemical assembly in living cells remains challenging. We have now developed an efficient and general platform to precisely control the formation of assemblies in living cells. We introduced an O-[bis(dimethylamino)phosphono]tyrosine protection strategy in the self-assembly motif as the Trojan horse, whereby the programmed precursors resist hydrolysis by phosphatases on and inside cells because the unmasking of the enzymatic cleavage site occurs selectively in the acidic environment of lysosomes. After demonstrating the multistage self-assembly processes in vitro by liquid chromatography/mass spectrometry (LC-MS), cryogenic electron microscopy (Cryo-EM), and circular dichroism (CD), we investigated the formation of site-specific self-assembly in living cells using confocal laser scanning microscopy (CLSM), LC-MS, and biological electron microscopy (Bio-EM). Controlling chemical assembly in living systems spatiotemporally may have applications in supramolecular chemistry, materials science, synthetic biology, and chemical biology.

Abstract
Fluorosulfuryl isocyanate (FSI, FSO2 NCO) is established as a reliable bis-electrophilic linker for stepwise attachment of an alcohol bearing module to an amine bearing module and thence a new module RO-C(=O)-NH-SO2 -NR'R'' is created. FSI's isocyanate motif fuses directly and quickly with alcohols and phenols, affording fluorosulfuryl carbamates in nearly quantitative yield. A new reagent and process to deliver the FSI-derived fluorosulfuryl carbamate fragment to amines are also developed. The resulting SVI -F motifs from step-1 are remarkably stable, given the great structural complexities in diverse products. In the step-2 reaction with amines, the best yield of the S-N linked products arise with water alone. This "on water" interfacial reactivity phenomenon is crucial, revealing the latent reactivity of SVI -F probe for potential covalent capture of proteins in vivo which is important in today's drug discovery. The scope of the SuFEx chemistry is largely expanded thereby and the facile entry to these phosphate-like connections should prove useful to click chemistry across diverse fields.

Abstract
In early drug discovery approaches, screening hits are often weak affinity binders that are difficult to characterize in structural detail, particularly towards obtaining the 3D structure of protein-ligand complexes at atomic resolution. NMR is the outstanding technique to tackle such problems, yet suffers from a tedious structure calculation process. NMR2 was recently developed to alleviate the laborious element of routine NMR structure calculation procedures and provides the structural information at protein-ligand interaction sites orders of magnitude faster than standard procedures. The NMR2 method was extended to weak binders and applied to the oncoproteins HDM2 and MDMX. The structure of the MDMX-SJ212 complex is reported with a Kd of approximately 0.7 μm; the complex structure of HDM2 with the mm affinity ligand #845 exhibits a new scaffold.

Abstract
Covalent inhibitors of lymphoid tyrosine phosphatase (LYP) were identified from a screen of the NIH Molecular Libraries Small Molecules Repository (MLSMR). Both of the two lead compounds identified have phosphotyrosine-mimetic benzoic acid moieties as well as electrophilic acrylonitrile groups. Inhibition kinetics of both compounds are consistent with covalent modification of the enzyme, with nanomolar KI and reciprocal millisecond kinact values, representing the best efficiency ratios (kinact /KI ) among currently reported covalent LYP inhibitors. Covalent inhibitors can provide longer efficacy and better selectivity than more conventional noncovalent inhibitors, and these lead compounds are an important step toward the development of protein tyrosine phosphatase (PTP)-targeted covalent therapeutic compounds.

Abstract
Phosphatases and kinases regulate the crucial phosphorylation post-translational modification. In spite of their similarly important role in many diseases and therapeutic potential, phosphatases have received arguably less attention. One reason for this is a scarcity of high-throughput phosphatase assays. Herein, a new real-time, dynamic protein tyrosine phosphatase (PTP) substrate microarray assay measuring product formation is described. PTP substrates comprising a novel 3-nitrophosphotyrosine residue are immobilized in discrete spots. After reaction catalyzed by a PTP a 3-nitrotyrosine residue is formed that can be detected by specific, sequence-independent antibodies. The resulting microarray was successfully evaluated with a panel of recombinant PTPs and cell lysates, which afforded results comparable to data from other assays. Its parallel nature, convenience, and low sample requirements facilitate investigation of the therapeutically relevant PTP enzyme family.

Abstract
Assay design is an important variable that influences the outcome of an inhibitor screen. Here, we have investigated the hypothesis that protein tyrosine phosphatase inhibitors with improved biological activity could be identified from a screen by using a biologically relevant peptide substrate, rather than traditional phosphotyrosine mimetic substrates. A 2000-member library of drugs and drug-like compounds was screened for inhibitors of lymphoid tyrosine phosphatase (LYP) by using both a peptide substrate (Ac-ARLIEDNE-pCAP-TAREG-NH₂, peptide 1) and a small-molecule phosphotyrosine mimetic substrate (difluoromethyl umbelliferyl phosphate, DiFMUP). The results demonstrate that compounds that inhibited enzyme activity on the peptide substrate had greater biological activity than compounds that only inhibited enzyme activity on DiFMUP. Finally, epigallocatechin-3,5-digallate was identified as the most potent inhibitor of lymphoid tyrosine phosphatase activity to date, with an IC₅₀ of 50 nM and significant activity in T-cells. Molecular docking simulations provided a first model for binding of this potent inhibitor to LYP; this will constitute the platform for ongoing lead optimization efforts.

Abstract
We screened a small library of thiuram disulfides for inhibition of lymphoid tyrosine phosphatase (LYP) activity. The parent thiuram disulfide, disulfiram, inhibited LYP activity in vitro and in Jurkat T cells, whereas diethyldithiocarbamate failed to inhibit LYP at the concentrations tested. Compound 13, an N-(2-thioxothiazolidin-4-one) analogue, was found to be the most potent LYP inhibitor in this series, with an IC50 value of 3 μM. Compound 13 inhibits LYP pseudo-irreversibly, as evidenced by the time-dependence of inhibition, with a K(i) value of 1.1 μM and a k(inact) value of 0.004 s⁻¹. The inhibition of LYP by compound 13 could not be reversed significantly by incubation with glutathione or by prolonged dialysis, but could be partially reversed by incubation with dithiothreitol. Compound 13 also inhibited LYP activity in Jurkat T cells.

Abstract
A concise total synthesis of spirastrellolide A methyl ester (1 a, R(1) =Me) as the parent compound of a series of highly cytotoxic marine macrolides is disclosed, which exploits and expands the flexibility of a synthesis plan previously developed by our group en route to the sister compound spirastrellolide F methyl ester (6 a, R(1) =Me). Key to success was the masking of the signature Δ(15,16) -bond of 1 a as a C16-carbonyl group until after the stereogenic center at C24 had been properly set by a highly selective hydrogenation of the C24 exo-methylene precursor 66. Conformational control over the macrocyclic frame allowed the proper stereochemical course to be dialed into this reduction process. The elaboration of the C16 ketone to the C15-C16 double bond was accomplished by a chemoselective alkenyl triflate formation followed by a palladium-catalyzed hydride delivery. The role of the ketone at C16 as a strategic design element is also evident up-stream of the key intermediate 66, the assembly of which hinged upon the addition of the polyfunctionalized dithiane 37 to the similarly elaborate aldehyde fragment 46. Other crucial steps of the total synthesis were an alkyl-Suzuki coupling and a Yamaguchi lactonization that allowed the Northern and the Southern sector of the target to be stitched together and the macrocyclic perimeter to be forged. The lateral chain comprising the remote C46 stereocenter was finally attached to the core region by a modified Julia-Kocienski olefination. The preparation of the individual building blocks led to some methodological spin-offs, amongst which the improved procedure for the N-O-bond cleavage of isoxazolines by zero-valent molybdenum and the ozonolysis of a double bond in the presence of other oxidation-prone functionality are most noteworthy. Preliminary biological data suggest that the entire carbon framework, that is the macrocyclic core plus the lateral chain, might be necessary for high cytotoxicity.

Abstract
Amongst different posttranslational events involved in cellular-signaling pathways, phosphorylation and dephosphorylation of proteins are the most prevalent. Aberrant regulations in the cellular phosphoproteome network are implicated in most major human diseases. Consequently, kinases and phosphatases are two of the most important groups of drug targets in medicinal research today. A major challenge in the understanding of protein phosphorylation and dephosphorylation is the sheer complexity of the phosphoproteome network and the lack of tools capable of studying protein phosphorylation and dephosphorylation as they occur in cells. We highlight herein various chemical biology tools that have emerged in the last decade for such studies. First, we discuss the use of small-molecule mimics of phosphoamino acids and their use in elucidating the function of protein phosphorylation and dephosphorylation. We also introduce recent advances in the field of activity-based protein profiling (ABPP) for proteome-wide detection of protein phosphorylation and dephosphorylation. We next discuss the key concepts in the design of peptide- and protein-based biosensors capable of real-time reporting of phosphorylation/dephosphorylation events. Finally, we highlight the application of peptide and small-molecule microarrays (SMMs), and their applications in high-throughput screening and discovery of new compounds related to phosphorylation/dephosphorylation.

Abstract
A library of resorcylic acid lactones (RAL) containing a cis-enone moiety targeting kinases bearing a cysteine residue within the ATP-binding pocket was prepared using a fluorous-mixture synthesis and evaluated against a panel of 19 kinases thus providing important structure-activity trends. Two new analogues were then profiled for their selectivity against a panel of 402 kinases providing the broadest evaluation of this pharmacophores' selectivity.

Abstract
We have optimized previously discovered benzoic acids 1, which are active as inhibitors of PTP1B and LMW-PTP, two protein tyrosine phosphatases that have emerged as attractive targets for the development of novel therapeutic agents for the treatment of diabetes, obesity, and cancer. Our efforts led to the identification of new and more potent analogues with appreciable selectivity toward human PTP1B and the IF1 isoform of human LMW-PTP.

Abstract
A gain-of-function mutant of the lymphoid phosphatase Lyp (PTPN22) has recently been implicated in type 1 diabetes and other autoimmune diseases, suggesting that small-molecule inhibitors of Lyp could be useful for the treatment of autoimmunity. Virtual ligand screening (VLS) was applied in the search for hit compounds. Two different docking algorithms, FlexX and ICM, were used to screen a library of 'drug-like' molecules against two different 3D structures, representing the catalytic site of Lyp in both the inactive 'open' and active 'closed' conformations. The top-scoring compounds of each VLS run were tested for their inhibitory activity against recombinant Lyp. Interestingly, VLS with both active and inactive conformations yielded very potent hits, with IC(50) values in the sub- and low-micromolar range. Moreover, many of these hits showed high docking scores only with one conformation. For instance, this was the case with several 2-benzamidobenzoic acid derivatives, which specifically docked into the inactive open form. Tryptophan fluorescence measurements further support a binding mode in which these compounds seem to stabilize the phosphatase in its inactive conformation.

Abstract
Natural products, their derivatives, and their analogues are among the most important sources for new drug candidates and tools for chemical biology and medicinal chemistry research. Therefore, there is a need for the development of efficient synthesis methods which give access to natural product derived and inspired compound collections. To meet this challenge, the requirements of multistep stereoselective syntheses, and the logic and methodology of natural product total synthesis need to be translated and adapted to the methods and formats for the synthesis of compound collections. Recent developments in the synthesis of natural product inspired compound collections having carbocyclic and heterocyclic scaffolds highlight the fact that this goal can be successfully attained. The progress made has paved the way for the integration of natural product inspired compound collections into medicinal chemistry and chemical biology research.
