Thermal analysis of a polymorphic azo dye derived from 2-amino-5-nitrothiazole

An azo dye, derived from 2-amino-5-nitrothiazole and a substituted N,N-dimethyl aniline, was studied by various techniques. Two sets of proton signals were obtained by NMR in CDCl3 solution, suggesting that two polymorphs coexist, however, only one set of signals is observed in DMSO solution. Differential scanning calorimetry and thermogravimetric analysis were used to confirm the existence of two forms. The events registered during thermal treatment of a sample were assigned to a glass transition, recrystallization and fusion of crystalline compounds. Hot-stage microscopy was used to obtain images of the dye samples at various stages of the heating program and these observations support the interpretation of the calorimetric results.

Modulated conjugation as a means of improving the intrinsic hyperpolarizability

A new strategy for optimizing the first hyperpolarizability based on theconcept of a modulated conjugated path in linear molecules is investiga ted. A series of seven novel chromophores with different types of conjugated paths were synthesized and characterized. Hyper-Rayleigh scatteringexperiments confirmed that modulated conjugation paths that include ben zene, thiophene, and/or thiazole rings in combination with azo and/or ethenyl linkages between dihydroxyethylamino donor groups and various acceptor groups result in enhanced intrinsic hyperpolarizabilities that exceed the long-standing apparent limit for two of the chromophores. The experimental results are analyzed and interpreted in the context of quantumlimits, which show that conjugation modulation of the bridge in donor/a cceptor molecules simultaneously optimizes the transition moments and the energy-level spacing.

Mechanistic Studies of the Palladium-Catalyzed Desulfinative Cross-Coupling of Aryl Bromides and (Hetero)Aryl Sulfinate Salts

Pyridine and related heterocyclic sulfinates have recently emerged as effective nucleophilic coupling partners in palladium-catalyzed cross-coupling reactions with (hetero)aryl halides. These sulfinate reagents are straightforward to prepare, stable to storage and coupling reaction conditions, and deliver efficient reactions, thus offering many advantages, compared to the corresponding boron-derived reagents. Despite the success of these reactions, there are only scant details of the reaction mechanism. In this study, we use structural and kinetic analysis to investigate the mechanism of these important coupling reactions in detail. We compare a pyridine-2-sulfinate with a carbocyclic sulfinate and establish different catalyst resting states, and turnover limiting steps, for the two classes of reagent. For the carbocyclic sulfinate, the aryl bromide oxidative addition complex is the resting state intermediate, and transmetalation is turnover-limiting. In contrast, for the pyridine sulfinate, a chelated Pd(II) sulfinate complex formed post-transmetalation is the resting-state intermediate, and loss of SO2 from this complex is turnover-limiting. We also investigated the role of the basic additive potassium carbonate, the use of which is crucial for efficient reactions, and deduced a dual function in which carbonate is responsible for the removal of free sulfur dioxide from the reaction medium, and the potassium cation plays a role in accelerating transmetalation. In addition, we show that sulfinate homocoupling is responsible for converting Pd(OAc)2 to a catalytically active Pd(0) complex. Together, these studies shed light on the challenges that must be overcome to deliver improved, lower temperature versions of these synthetically important processes.

Visualizing Compartmentalized Cellular Mg2+ on Demand with Small-Molecule Fluorescent Sensors

The study of intracellular metal ion compartmentalization and trafficking involved in cellular processes demands sensors with controllable localization for the measurement of organelle-specific levels of cations with subcellular resolution. We introduce herein a new two-step strategy for in situ anchoring and activation of a fluorescent Mg2+ sensor within an organelle of choice, using a fast fluorogenic reaction between a tetrazine-functionalized pro-sensor, Mag-S-Tz, and a strained bicyclononyne conjugated to a genetically encoded HaloTag fusion protein of known cellular localization. Protein conjugation does not affect the metal-binding properties of the o-aminophenol-N,N,O-triacetic acid (APTRA)-based fluorescent indicator, which displays a dissociation constant Kd = 3.1 mM suitable for the detection of low millimolar concentrations of chelatable Mg2+ typical of the intracellular environment. We demonstrate the application of our sensing system for the ratiometric detection of Mg2+ in target organelles in HEK 293T cells, providing the first direct comparison of subcellular pools of the metal without interfering signal from other compartments. Activation of the fluorescence in situ through a fluorogenic conjugation step effectively constrains the fluorescence signal to the locale of interest, thus improving the spatial resolution in imaging applications and eliminating the need for washout of mislocalized sensor. The labeling strategy is fully compatible with live cell imaging, and provides a valuable tool for tracking changes in metal distribution that to date have been an unsolved mystery in magnesium biology.

Catalytic Synthesis of ?Super? Linear Alkenyl Arenes Using an Easily Prepared Rh(I) Catalyst

Linear alkyl benzenes (LAB) are global chemicals that are produced by acid-catalyzed reactions that involve the formation of carbocationic intermediates. One outcome of the acid-based catalysis is that 1-phenylalkanes cannot be produced. Herein, it is reported that [Rh(mu-OAc)(eta2-C2H4)2]2 catalyzes production of 1-phenyl substituted alkene products via oxidative arene vinylation. Since C C bonds can be used for many chemical transformations, the formation of unsaturated products provides a potential advantage over current processes that produce saturated alkyl arenes. Conditions that provide up to a 10:1 linear:branched ratio have been achieved, and catalytic turnovers >1470 have been demonstrated. In addition, electron-deficient and electron-rich substituted benzenes are successfully alkylated. The Rh catalysis provides ortho:meta:para selectivity that is opposite to traditional acid-based catalysis.

Searching for new cures for tuberculosis: Design, synthesis, and biological evaluation of 2-methylbenzothiazoles

The actual development and clinical use of new therapeutics for tuberculosis (TB) have remained stagnant for years because of the complexity of the disease process, the treatment of which at present requires the administration of drug combinations over a 6month period. There is thus an urgent need for the discovery and development of novel, more active, and less toxic anti-TB agents. In this study, we report on the chemistry and biology of a series of potent 5-(2-methylbenzothiazol-5-yloxymethyl) isoxazole-3-carboxamide derivatives, which proved to be active against replicating Mycobacterium tuberculosis (Mtb) H37Rv. The most potent compounds 7j and 7s were found to inhibit Mtb growth at micromolar concentrations, with MICvalues of 1.4 and 1.9 muM, respectively. Impressively, all active compounds were nontoxic toward Vero cells (IC50 > 128 muM). Moreover, the best of these compounds were also tested against protozoan parasites, and some of these compounds were found to show activity, especially against Plasmodium falciparum. These studies thus suggest that certain 2-methylbenzothiazole based compounds may serve as promising lead scaffolds for further elaboration as anti-TB drugs and as possible antimalaria drugs. 2009 American Chemical Society.

Novel small molecule bradykinin B2 receptor antagonists

Blockade of the bradykinin B2 receptor provides therapeutic benefit in hereditary angioedema (HAE) and potentially in many other diseases. Herein, we describe the development of highly potent B2 receptor antagonists with a molecular weight of approximately 500 g/mol. First, known quinoline-based B2 receptor antagonists were stripped down to their shared core motif 53, which turned out to be the minimum pharmacophore. Targeted modifications of 53 resulted in the highly water-soluble lead compound 8a. Extensive exploration of its structure-activity relationship resulted in a series of highly potent B2 receptor antagonists, featuring a hydrogen bond accepting functionality, which presumably interacts with the side chain of Asn-107 of the B2 receptor. Optimization of the microsomal stability and cytochrome P450 inhibition eventually led to the discovery of the highly potent and orally available B2 receptor antagonist 52e (JSM10292), which showed the best overall properties.
