ENZYMATIC FORMATION OF PROTOPINES BY A MICROSOMAL CYTOCHROME P-450 SYSTEM OF CORYDALIS VAGINANS

A microsomal cytochrome P-450-NADPH dependent enzyme which hydroxylates stereo- and regiospecifically carbon atom 14 of (S)-cis-N-methyltetrahydroprotoberberines has been discovered in a number of plant cell cultures originating from species containing protopine alkaloids; the monooxygenase was solubilized, partially purified (100-fold) and characterized.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 1081-17-0

Probing selectivity in recognition-mediated dynamic covalent processes

Two simple recognition-mediated dynamic Diels-Alder systems are used to probe the role of kinetics and thermodynamics in determining the equilibrium position in exchanging libraries and the time taken to reach that equilibrium. The selectivity expressed by recognition-driven dynamic processes is demonstrated to be less than the free-energy difference between the components as a result of compensatory effects arising from the extent of conversion to products within the library.

N,N’-DIMALEIMIDES IN THE DIELS-ALDER REACTION. I. KINETICS OF THE UNCATALYZED REACTION WITH trans,trans-1,4-DIPHENYLBUTADIENE AND 1,3-DIPHENYLISOBENZOFURAN

The kinetic behavior of a series of diimides, in which the maleimide rings are linked through various bridges, in the Diels-Alder reaction with trans,trans-1,4-diphenylbutadiene and 1,3-diphenylisobenzofuran was studied.The energies of charge transfer were determined and the electron affinities were calculated by spectrophotometry of the charge-transfer complexes between the imides and hexamethylbenzene.Although the rates of reaction of the bisimides with the investigated dienes differ by seven orders of magnitude, the general type of “diene-donor, dienophile-acceptor” reaction is preserved.

Pyrrolidinohydroquinazolines – A novel class of CCR3 modulators

A novel class of CCR3 modulators is described. Starting with lead compound 4a (Ki: 110 nM), which turned out to be an antagonist of eotaxin at the CCR3 receptor, further optimization led to compound 8b (Ki: 28 nM), which surprisingly proved to be an agonist.

Aza-Peptide Michael Acceptors: A New Class of Inhibitors Specific for Caspases and Other Clan CD Cysteine Proteases

Aza-peptide Michael acceptors are a new class of irreversible inhibitors that are highly potent and specific for clan CD cysteine proteases. The aza-Asp derivatives were specific for caspases, while aza-Asn derivatives were effective legumain inhibitors. Aza-Lys and aza-Orn derivatives were potent inhibitors of gingipain K and clostripain. Aza-peptide Michael acceptors showed no cross reactivity toward papain, cathepsin B, and calpain.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! Read on for other articles about 2144-40-3!, 73286-71-2

Synthesis and evaluation of novel 4-[(3H,3aH,6aH)-3-phenyl)-4,6-dioxo-2- phenyldihydro-2H-pyrrolo[3,4-d]isoxazol-5(3H,6H,6aH)-yl]benzoic acid derivatives as potent acetylcholinesterase inhibitors and anti-amnestic agents

The present study was designed to synthesize and evaluate pyrrolo-isoxazole benzoic acid derivatives as potential acetylcholinesterase (AChE) inhibitors for the management of Alzheimer’s disease. The synthesis of pyrrolo-isoxazole benzoic acid derivatives involved ring opening cyclization of p-aminobenzoic acid with maleic anhydride to yield maleanilic acid, which in turn afforded N-arylmaleimide via ring closed cyclization. Azomethine-N-oxides were obtained by condensation of N-arylhydroxylamine with differently substituted benzaldehydes followed by refluxing of N-arylmaleimide with differently substituted azomethine-N-oxides to pyrrolo-isoxazole benzoic acid derivatives as cis- and trans-stereoisomers. The synthesized compounds were evaluated in vitro for AChE inhibitory activity in rat brain homogenate with donepezil as standard AChE inhibitor. Thereafter, the most potent test compound was evaluated for in vitro butyrylcholinesterase inhibitory activity and in vivo memory evaluation in scopolamine (0.4 mg/kg)-induced amnesia in mice by employing Morris water maze test. All pyrrolo-isoxazole benzoic acid derivatives demonstrated potent AChE inhibitory activity. Most of compounds exhibited similar activity to donepezil and four of them (7h, 7i, 8i, and 8h, IC50 = 19.1 ¡À 1.9-17.5 ¡À 1.5 nM) displayed higher inhibitory activity as compared to donepezil (21.5 ¡À 3.2 nM) with compound 8ia (IC50 = 17.5 ¡À 1.5 nM) being the most active one. The test compound 8ia also ameliorated scopolamine-induced amnesia in mice in terms of restoration of time spent in target quadrant (TSTQ) and escape latency time (ELT). It may be concluded that pyrrolo-isoxazole benzoic acid derivatives may be employed as potential AChE inhibitors.

Applicability of a Monolithic Column for Separation of Isoquinoline Alkalodis from Chelidonium majus Extract

Isoquinoline alkaloids are the main group of secondary metabolites present in Chelidonium majus extracts, and they are still the object of interest of many researchers. Therefore, the development of methods for the investigation and separation of the alkaloids is still an important task. In this work, the application potential of a silica-based monolithic column for the separation of alkaloids was assessed. The influence of the organic modifier, temperature, salt concentration, and pH of the eluent on basic chromatographic parameters such as retention, resolution between neighboring peaks, chromatographic plate numbers, and peak asymmetry were investigated. Based on the obtained results, a gradient elution program was developed and used to separate and quantitatively determine the main alkaloids in a Chelidonium majus root extract.
