The synthesis and cholinesterase inhibitory activities of solasodine analogues with seven-membered F ring

Solasodine analogues containing a seven-membered F ring with a nitrogen atom placed at position 22a were prepared from diosgenin or tigogenin in a four-step synthesis comprising of the simultaneous opening of the F-ring and introduction of cyanide in position 22 alpha, activation of the 26-hydroxyl group as mesylate, nitrile reduction, and N-cyclization. Solasodine, six obtained 22a(N)-homo analogues, as well as four 26a-homosolasodine derivatives and their open-chain precursors (13 in total) were tested as potential inhibitors of acetyland butyryl-cholinesterases and showed activity at micromolar concentrations. The structure-activity relationship study revealed that activities against studied esterases are affected by the structure of E/F rings and the substitution pattern of ring A. The most potent compound 8 acted as non-competitive inhibitors and exerted IC50 = 8.51 mu M and 7.05 mu M for eeAChE and eqBChE, respectively. Molecular docking studies revealed the hydrogen bond interaction of 8 with S293 of AChE; further rings are stabilized via hydrophobic interaction (ring A) or interaction with Y341 and W286 (rings B and C). Biological experiments showed no neurotoxicity of differentiated SH-SY5Y cells. More importantly, results from neuroprotective assay based on glutamate-induced cytotoxicity revealed that most derivatives had the ability to increase the viability of differentiated SH-SY5Y cells in comparison to galantamine and lipoic acid assayed as standards. The newly synthesized solasodine analogues are able to inhibit and to bind cholinesterases in noncompetitive mode of inhibition and exhibited neuroprotection potential of differentiated neuroblastoma cells after Glu-induced toxicity.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 274-09-9, in my other articles.

Reactions of ethyl methylsulfonylpyruvate and its sodium salt with a mixture of aromatic aldehyde and arylamine

The reactions of ethyl methylsulfonylpyruvate and its sodium salt with a mixture of aromatic aldehyde and arylamine afforded 1,5-diaryl-3-hydroxy-4-methylsulfonyl-3-pyrrolin-2-ones. The spatial structure of 1,5-diplienyi-3-liydroxy-4-methylsulfonyl-3-pyrrolin-2-one was established by X-ray diffraction analysis.

Diastereoselective cyclisation of N-alkenylideneamines into 3,4-dihydro–2H-pyrrol-1-ium halides

A number of new chiral 2-(alpha-bromoalkyl)pyrrolinium salts and 2-(alpha-selenoalkyl)pyrrolidines were synthesized by the halocyclisation and selenocyclisation, respectively, of N-(alkenylidene)alkylamines and subsequent reduction. These cyclisations were implemented in a diastereomeric fashion for the first time. Substrate control (starting imines possessing chirality in the N-alkyl or the N-alkenyl substituent) and reagent control (chiral organoselenenyl bromides) were applied. Asymmetric induction by stereocentres of the alkenylidene or double asymmetric induction by chiral selenenyl bromides on unsaturated imines with a chiral N-alkyl group resulted in diatereoselectivities up to 84:16.

Morphology evolution, mechanical properties, Mullins effect, and its reversibility of polylactide/nitrile butadiene rubber thermoplastic vulcanizates plasticized by dioctyl phthalate

Thermoplastic vulcanizates (TPVs) based on polylactide (PLA)/nitrile butadiene rubber (NBR) blends were prepared by dynamic vulcanization where the PLA phase was plasticized by dioctyl phthalate (DOP), and the influence of DOP dosage on mechanical properties, morphology evolution, Mullins effect, and its reversibility were investigated systematically. The experimental results indicated that the mechanical properties of PLA/NBR TPVs were improved significantly with the addition of DOP. Compared with that of the PLA/NBR TPVs, the Shore A hardness was decreased obviously, while the elongation at break was increased slightly with increasing DOP dosage. Mullins effect results showed that the TPVs incorporated with DOP had the relatively lower stress-softening effect. The recovery ability of the maximum stress could be remarkably enhanced by increasing heat treatment temperature. Morphology studies showed that the network microstructure of the co-continuous phases was denser with the increasing dynamic vulcanization time; however, the network microstructure of the co-continuous was changed slightly with the addition of DOP.

Synthesis of C-14-labelled myosmine, [2 ‘-C-14]-3-(1-pyrrolin-2-yl)pyridine

C-14-Labelled myosmine ([2’-C-14]-3-(1-pyrrolin-2-yl)pyridine) was synthesized for autoradiography studies starting from [carboxyl-C-14]-nicotinic acid by initial esterification of the latter in the presence of 1,1,1-triethoxyethane. Without any purification the ethyl nicotinate formed was directly reacted with N-vinyl-2-pyrrolidinone in the presence of sodium hydride, yielding C-14-labelled myosmine. The product was purified by silica gel column chromatography. The radiochemical yield was 15% and the specific activity 55.2 mCi/mmol. Copyright (C) 2003 John Wiley Sons, Ltd.
