Abstract
There have been significant advances in the formulation and stabilization of proteins in the liquid state over the past years since our previous review. Our mechanistic understanding of protein-excipient interactions has increased, allowing one to develop formulations in a more rational fashion. The field has moved towards more complex and challenging formulations, such as high concentration formulations to allow for subcutaneous administration and co-formulation. While much of the published work has focused on mAbs, the principles appear to apply to any therapeutic protein, although mAbs clearly have some distinctive features. In this review, we first discuss chemical degradation reactions. This is followed by a section on physical instability issues. Then, more specific topics are addressed: instability induced by interactions with interfaces, predictive methods for physical stability and interplay between chemical and physical instability. The final parts are devoted to discussions how all the above impacts (co-)formulation strategies, in particular for high protein concentration solutions.'

Abstract
Small molecule inhibitors often only block a subset of the cellular functions of their protein targets. In many cases, how inhibiting only a portion of a multifunctional protein's functions affects the state of the cell is not well-understood. Therefore, tools that allow the systematic characterization of the cellular interactions that inhibitor-bound proteins make would be of great utility, especially for multifunctional proteins. Here, we describe a chemoproteomic strategy for interrogating the cellular localization and interactomes of inhibitor-bound kinases. By developing a set of orthogonal inhibitors that contain a trans-cyclooctene (TCO) click handle, we are able to enrich and characterize the proteins complexed to a drug-sensitized variant of the multidomain kinase Src. We show that Src's cellular interactions are highly influenced by the intermolecular accessibility of its regulatory domains, which can be allosterically modulated through its ATP-binding site. Furthermore, we find that the signaling status of the cell also has a large effect on Src's interactome. Finally, we demonstrate that our TCO-conjugated probes can be used as a part of a proximity ligation assay to study Src's localization and interactions in situ. Together, our chemoproteomic strategy represents a comprehensive method for studying the localization and interactomes of inhibitor-bound kinases and, potentially, other druggable protein targets.

Abstract
Protein oxidation by reactive oxygen species has been associated with aging and neurodegenerative disorders, and histidine is one of the major oxidation targets due to its metal-chelating property and susceptibility to metal-catalyzed oxidation. 2-Oxohistidine, the major product of histidine oxidation, has been recently identified as a stable marker of oxidative damage in biological systems, but its biophysical and biochemical properties are understudied, partly because of difficulties in its chemical synthesis. We developed an efficient method to generate a 2-oxohistidine side chain using metal-catalyzed oxidation, applicable to both monomers and peptides. By optimizing reagent ratios and pH buffering in Cu(2+) /ascorbate/O2 reaction system, we improved the yield more than tenfold compared to reported conditions, which allowed us to obtain homogeneously modified 2-oxohisidine peptides for further studies. Analysis of 2-oxohistidine-containing model peptides by liquid chromatography-tandem mass spectrometry demonstrated increased retention time in reverse-phase chromatography and general stability of 2-oxohistidine under electrospray ionization and collision-induced dissociation. Thus, large-scale analysis of 2-oxohistidine-modified proteome should be feasible using shotgun protein mass spectrometry, and we were able to observe such peptides in proteomics datasets. The feasibility of acquiring purified peptide probes and peptide antigens containing 2-oxohistidine will help advance the study of this non-enzymatic posttranslational modification.

Abstract
The copper-catalyzed azide-alkyne cycloaddition (CuAAC) reaction, optimized for biological molecules in aqueous buffers, has been shown to rapidly label mammalian cells in culture with no loss in cell viability. Metabolic uptake and display of the azide derivative of N-acetylmannosamine developed by Bertozzi, followed by CuAAC ligation using sodium ascorbate and the ligand tris(hydroxypropyltriazolyl)methylamine (THPTA), gave rise to abundant covalent attachment of dye-alkyne reactants. THPTA serves both to accelerate the CuAAC reaction and to protect the cells from damage by oxidative agents produced by the Cu-catalyzed reduction of oxygen by ascorbate, which is required to maintain the metal in the active +1 oxidation state. This procedure extends the application of this fastest of azide-based bioorthogonal reactions to the exterior of living cells.

Abstract
Drug discovery remains a top priority in medical science. The phenomenon of drug resistance has heightened the need for both new classes of pharmaceutical, as well as novel modes of action. A new paradigm for drug activity is presented, which includes both recognition and subsequent irreversible inactivation of therapeutic targets. Application to both RNA and enzyme therapeutic targets has been demonstrated, while incorporation of both binding and catalytic centers provides a double-filter mechanism for improved target selectivity and lower dosing. In contrast to RNA targets that are subject to strand scission chemistry mediated by ribose H-atom abstraction, proteins appear to be inactivated through oxidative damage to amino acid side chains around the enzyme active site. Methods to monitor both intracellular delivery and activity against RNA targets have been developed based on plasmid expression of the green fluorescent protein (GFP). Herein, the activity of representative metallodrugs is described in the context of both in vitro and cellular assays, and the mechanism of action is discussed. Studies with scavengers of reactive oxygen species (ROS) confirmed hydrogen peroxide to be an obligatory diffusible intermediate, prior to formation of a Cu-bound hydroxyl radical species generated from Fenton-type chemistry.

Abstract
A series of metallopeptides based on the amino terminal copper/nickel (ATCUN) binding motif have been evaluated as classical inhibitors and catalytic inactivators of both rabbit and human angiotensin-converting enzyme (hACE), and human endothelin-converting enzyme 1 (hECE-1). The cobalt complex [KGHK-Co(NH3)2]2+, where KGHK is lysylglycylhistidyllysine, displayed similar K(I) and IC50 values to those found for [KGHK-Cu]+, in spite of the enhanced charge, and so either the influence of charge is offset by the steric influence of the axially coordinated ammine ligands, or binding is dominated by contributions from the amino acid side chains, especially the C-terminal lysine that mimics the binding pattern observed for lisinopril. Moreover, the inhibition observed for [KGHK-Co(NH3)2]2+ contrasts with the activation of hACE by Co2+(aq), reflecting the stimulation of enzyme activity following replacement of the catalytic zinc cofactor by cobalt ion at each of the two active sites. Quantitative analysis of the dose-dependent stimulation of activity by Co2+(aq) yielded apparent affinities of 1.3 +/- 0.2 and 56 +/- 8 microM for the two sites in the presence of saturating Zn2+ (10 microM). Catalytic inactivation of hACE by [KGHK-Cu]+ at subsaturating concentrations had previously been characterized, with k(obs) = 2.9 +/- 0.5 x 10(-2) min(-1). Under similar conditions, the same complex is found to catalytically inactivate hECE-1, with k(obs) = 2.12 +/- 0.16 x 10(-2) min(-1), demonstrating the potential for dual-action activity against two key drug targets in cardiovascular disease. Irreversible inactivation of a drug target represents a novel mechanism of drug action that complements existing classical inhibitor strategies that underlie current drug discovery efforts.

Abstract
The antioxidant activity of tannic acid (TA), a plant polyphenol claimed to possess antimutagenic and anticarcinogenic activities, was studied by monitoring (i) 2-deoxyribose degradation (a technique for OH detection), (ii) ascorbate oxidation, (iii) ascorbate radical formation (determined by EPR analysis) and (iv) oxygen uptake induced by the system, which comprised Fe(III) complexes (EDTA, nitrilotriacetic acid (NTA) or citrate as co-chelators), ascorbate and oxygen. TA removes Fe(III) from the co-chelators (in the case of EDTA, this removal is slower than with NTA or citrate), forming an iron-TA complex less capable of oxidizing ascorbate into ascorbate radical or mediating 2-deoxyribose degradation. The effectiveness of TA against 2-deoxyribose degradation, ascorbate oxidation and ascorbate radical formation was substantially higher in the presence of iron-NTA (or iron-citrate) than with iron-EDTA, which is consistent with the known formation constants of the iron complexes with the co-chelators. Oxygen uptake and 2-deoxyribose degradation induced by Fe(II) autoxidation were also inhibited by TA. These results indicate that TA inhibits OH formation induced by Fe(III)/ascorbate/O(2) mainly by arresting Fe(III)-induced ascorbate oxidation and Fe(II) autoxidation (which generates Fe(II) and H(2)O(2), respectively), thus limiting the production of Fenton reagents and OH formation. We also hypothesize that the Fe(II) complex with TA exhibits an OH trapping activity, which explains the effect of TA on the Fenton reaction.
