Structure-activity study of pyridine derivatives inhibiting thromboxane synthetase

The relationship between the structure of the side chain of pyridine derivatives and the inhibitory potency towards thromboxane synthetase was quantitatively analyzed by the adaptive least-squares (ALS) method. The main descriptors concerning the molecular structure used in the analysis were estimated on the basis of the minimum energy conformation obtained from MINDO/3 molecular orbital calculation. All of 27 pyridine derivatives were recognized correctly by the best discriminant function. Validity of the discriminant function was tested by the leave-one-out technique. The activity ratings of 23 compounds could be predicted correctly with the descriptors used in the best function. Application of this relationship to the design of inhibitors and the mode of enzyme-inhibitor interaction were discussed.

Kinetics and Mechanism of Halogen-bridge Cleavage in Dimethylaminomethylphenyl-C1,N Pallada- and Platina-cycles by Pyridines. Pressure Effects, and Crystal Structures of the N,N-cis Reaction Product, its N,N-trans Orthometallated Analogue and a Dimer of Similar Reactivity

An ambient and high-pressure stopped-flow kinetic study of the halogen-bridge cleavage reaction in the pallada- and platina-cycles <2> (M = Pd or Pt; R = H, 4-MeO, 5-Me or 5-F; X = Cl or I) by a series of substituted pyridines in chloroform as solvent revealed that it is a fast, associatively driven second-order process, with strong steric rather than electronic demands.Substituent effects and activation parameters (DeltaH(excit.),DeltaS(excit.) and DeltaV(excit.)) were in full accord with the proposed associative mechanism.The Pd dimers transformed into N,N-trans monomers of the type (py = pyridine).In contrast, the Pt counterparts afford N,N-cis species under the same conditions.The geometry of the N,N-cis complex X(py)>, as well as of the N,N-trans platinacycle Cl(py)>, has been confirmed by X-ray crystallography.The most striking structural differences in the N,N-cis and N,N-trans related platinacycles are the Pt-Cl and Pt-N(py) bond distances <2.300(1) and 2.408(5), 2.138(4) and 2.02(1) Angstroem, respectively>.The crystal structure of trans-<(n-Bu3P)IPd(mu-I)2PdI(P-n-Bu3)> has also been determined and used to account for its similar reactivity to <2> in the bridge-splitting reaction.

The chemistry of univalent metal beta-diketiminates

The easily electronically and sterically tunable beta-diketiminates are widely used auxiliary ligands for the creation of a wide range of metal complexes with various oxidation states in all groups of the periodic table. This review article highlights the recent advances of univalent beta-diketiminatometal complexes. Such low-valent metals supported by beta-diketiminates display remarkable metal-metal bonding, organic functionality and small molecule activations, reactivity relevant to biological active sites, and catalytic reactivity.

Copper-catalyzed selective oxygenation of methyl and benzyl substituents in pyridine with O2

A selective oxygenation of picolines and their derivatives has been achieved by usingasimple copper salt as a catalyst and molecular oxygen as an oxidant, where the alpha-position of the alkyl substituent is selectively oxidized to give the corresponding aldehydes or ketones. Addition of a catalytic amount of water enhances the catalytic activity, which could be attributed to the role of the proton donor to activate the substrates.

Oxidative degradation of AMP/MEA blends for post-combustion CO2 capture

The oxidative degradation of aqueous, concentrated 2-amino-2-methyl-1- propanol (AMP)/monoethanolamine (MEA) mixture has been investigated in batch reactors at temperatures in the range of 100-140C, and oxygen pressures in the range of 250-350 kPa. The oxidation pathway of individual AMP was proposed before attempting to investigate the oxidation of AMP/MEA blend. As compared with degradation of single MEA and AMP, no cross product was found in the degraded AMP/MEA blend under the experimental conditions. This result showed that AMP and MEA could be oxidized in parallel in the mixture. Both the overall degradation rates of MEA and AMP increased with raising temperature and oxygen partial pressure. MEA degraded faster than AMP in the blend under all the experimental conditions. The degradation rate of AMP decreased indicating MEA protects AMP from oxidation in the mixture when initial MEA concentration was increased.

Aryne [3 + 2] cycloaddition with N-sulfonylpyridinium imides and in situ generated N-sulfonylisoquinolinium imides: A potential route to pyrido[1,2-b]indazoles and indazolo[3,2-a]isoquinolines

The aryne [3 + 2] cycloaddition process with pyridinium imides breaks the aromaticity of the pyridine ring. By equipping the imide nitrogen with a sulfonyl group, the intermediate readily eliminates a sulfinate anion to restore the aromaticity, leading to the formation of pyrido[1,2-b]indazoles. The scope and limitation of this reaction are discussed. As an extension of this chemistry, N-tosylisoquinolinium imides, generated in situ from N?-(2-alkynylbenzylidene)-tosylhydrazides via an AgOTf-catalyzed 6-endo-dig electrophilic cyclization, readily undergo aryne [3 + 2] cycloaddition to afford indazolo[3,2-a]-isoquinolines in the same pot, offering a highly efficient route to these potential anticancer agents.

Finite molecular assemblies in the organic solid state: toward engineering properties of solids

Assemblies of organic molecules that form finite structures represent targets for crystal engineers that can exhibit properties largely independent of crystal packing. Such finite molecular assemblies can display function, such as host-guest behavior and chemical reactivity. Here, we provide a review of finite molecular assemblies characterized in the organic solid state. The assemblies are classified as being either purely synthetic or functional. Examples from both the areas are presented and discussed.
