Tubulin binding compounds represent one of the most attractive targets for anticancer drug development. They broadly fall into two categories viz., tubulin polymerization inhibitors, which block microtubule growth and destabilize microtubules like vinca alkaloids and cryptophycins, and the others, which polymerize microtubules into hyperstable forms represented by family of taxanes. In this context, we aimed at design and synthesis of cryptophycins based macrocyclic depsipeptides, which are synthetically more accessible, however have the basic information to target tubulins and establish structure activity relationship (SAR). Thus, a new class of cryptophycins based marocyclic depsipeptides with a truncated epoxide chain were synthesized as potential tubulin inhibitors. The resultant lead analogues 15a and 16a exhibited good anti-cancer activity, induced apoptosis, caused block/delay in cell cycle as well as significantly reduced the expression of alpha- and beta-tubulins. Molecular modelling studies show that 15a and 16a bind in the same domain as that of cryptophycins.

The products of the condensation reactions of twenty-six different 1,2-amino alcohols with excess aqueous formaldehyde were identified, with the help of a simple and effective analytical technique based on mass spectroscopy. With a few exceptions, which arise from steric or solubility effects, most amino alcohols form bis(oxazolidine)methane adducts preferentially.

The aim of this study was to evaluate the physicochemical and textural characteristics and volatile compounds of Kazakh dry-cured beef made in China. Two types of Kazakh dry-cured beef were investigated: Kazakh drycured beef made with smoking and spices (T1) and without smoking and spices (T2). There were significant (P < 0.05) differences in values of aw, moisture, L?, cohesiveness and chewiness between the two types. A total of 86 volatile compounds were isolated by solid phase microextraction-gas chromatography/mass spectrometry (SPME-GC/MS). Hydrocarbons were the most abundant in T1 products and aldehydes in T2 products. Principal component analysis showed that the first principal component (PC1) was highly related to smoke derivatives- naphthalene, 2-cyclopenten-1-one derivatives, 4-methyl-4-hepten-3-one, acetophenone, 2,3-dihydro-1H-Inden-1-one, 2-furanmethanol, methoxy-phenyl-oxime, furfural, 1-(2-furanyl)-ethanone and phenols-and the second principal component (PC2) to lipid derivatives-straight-chain aliphatic aldehydes, methyl ketone, straight-chain alcohols and 2-pentyl-furan.

A series of enantiopure ligands based on the aminoindanol scaffold, but differing in regio-and stereochemistry has been synthesized. These ligands have been conveniently derivatized and their catalytic efficiency in different enantioselective reactions has been screened to determine privileged candidates with respect to regio- and stereochemistry for each considered process. The nature of the amino substituent has been optimized for specific applications and this has led to the development of an efficient method for the preparation of bulky bicyclic amines by reductive amination.

Irreversible inhibitors are therefore the equivalent of poisons in heterogeneous catalysis.126456-43-7, Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction by binding to a specific portion of an enzyme and thus slowing or preventing a reaction from occurring. 126456-43-7, name is (1S,2R)-1-Amino-2,3-dihydro-1H-inden-2-ol.

A stereodynamic chemosensor having a parallel arrangement of a substrate-binding salicylaldehyde unit and an adjacent pyridyl N-oxide fluorophore undergoes rapid condensation with chiral amino alcohols and subsequent asymmetric transformation of the first kind toward a single rotamer. Crystallographic analysis shows that the concomitant central-to-axial chirality imprinting is controlled by minimization of steric repulsion and by intramolecular hydrogen bonding between the bound amino alcohol and the proximate N-oxide group. The substrate binding event results in strong CD effects and characteristic fluorescence changes which can be used for instantaneous in situ determination of the absolute configuration, enantiomeric composition and total concentration of a variety of chiral amino alcohols. This chemosensing approach avoids time-consuming workup and purification steps, and it is applicable to minute sample amounts which reduces the use of solvents and limits waste production.

The study of the adduct formation of Ni(II)di(2,4-dimethylphenyl)cabazonate has been undertaken by synthesising and characterising it by magnetic susceptibility, IR and 1H-NMR spectral measurements. The Ni(II) chelate forms adducts with heterocyclic nitrogen bases, spectrophotometeric method has been employed for the study of the adduct formation in a monophase chloroform. Both bidentate and unsaturated monodenate heteronuclear nitrogen bases form hexa-coordinated adducts with 1:1 stoichiomety (metal chelate, base). However, the saturated nitrogen bases form penta-coordinated adducts with 1:1 stoichiometry. The results are discussed in terms of basicity and steric factors of the bases.
