The study of genotoxicity of two newly synthesized pyrrolinone derivatives on L5178Y mouse lymphoma and bone marrow cells

Genotoxic activity of two newly synthesized pyrrolinone derivatives (lactone (PTB) and lactame (PTP)) was studied both in vitro and in vivo. The substances were incubated with L5178Y mouse lymphoma cells for 4 h, then washed from the substances, and incubated for 18 h. PTP induced significantly increased number of micronuclei (MN) only at the highest dose used (1000 mug/ml). The 20-fold increase of the concentration of PTP led to 2.4-fold increase of the number of MN. PTP wasn’t toxic for lymphoma cells in the applied concentration range. In contrast, PTB induced significantly increased number of MN in lymphoma cells beginning from the concentration of 50 mug/ml and was toxic for lymphoma cells at concentrations of 500 mug/ml and higher. In the comet assay with L5178Y mouse lymphoma cells both substances were active at all concentrations used (PTP at concentrations of 50 mug/ml and 100 mug/ml, and PTB at concentrations of 100 mug/ml and 250 mug/ml). Acute toxicity and MN-inducing activity of compounds were studied on Swiss albino mice. PTB was substantially more toxic for mice than PTP (LD50 was 200 mg/kg and 370 mg/kg respectively). In mouse bone marrow polychromatic erythrocytes PTP induced significantly increased number of MN only at a dose equal to 1/2 of LD50. In contrast, PTB was mutagenic at all doses used -1/2, 1/5, and 1/10 of LD50. At equitoxic doses PTB induced more than 2-fold and 3.5-fold increased levels of MN compared with PTP (1/2 and 1/5 of LD50 respectively). The replacement of =NH group to =O group in chemical structure of pyrrolinone derivatives leads to substantial increase in acute toxicity for mice (1.85-fold) and MN induction activity both in vivo and in vitro.

ANALYTICAL INVESTIGATION OF THE FLAVOR OF CUPUACU (THEOBROMA-GRADIFLORUM SPRENG)

The Cupuacu (Theobroma grandiflorum Spreng.) tree, a relative of cocoa (Theobroma cacao L), is indigenous to Amazonia, Brazil. The pulp of its fruits is consumed e.g. in juices, ice creams or bakery fillings, especially in Brazilian Belem region. As a part of our ongoing project aimed at the investigation of less common tropical fruit flavors, the flavor of cupuacu pulp was analyzed. Flavor extracts were prepared by using vacuum distillation, solid phase extraction and simultaneous steam distillation-extraction (SDE). The concentrates were evaluated sensorially, and analyzed by means of GC-, GC/MS- and GC-O techniques. Several major to minor components of sensory importance for the cupuacu flavor were identified along with a number of trace constituents with very high flavor impact. The portion of short-chain acids, responsible for the typical acidic aspects of cupuacu flavor, is mainly associated with the fibrous part of the pulp, whereas the distillate is dominated by several esters. 2-Ethyl-5-methyl-4-hydroxy-3(2H)-furanone could be identified as an important trace component in the concentrate obtained by solid-phase extraction on RP-18 material. Thermal treatment of cupuacu pulp produced additionally a bread-like flavor impression, for which 2-acetyl-1-pyrrolin was found to be responsible.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.I hope my blog about 112275-50-0 is helpful to your research. COA of Formula: https://www.ambeed.com/products/112275-50-0.html.

Inactivation of Thioglucosidase from Sinapis alba (White Mustard) Seed by Metal Salts

The glucosinolates which are specialized plant metabolites of Brassica vegetables are prone to hydrolysis catalyzed by an endogenous enzyme myrosinase (thioglycoside hydrolase, thioglucosidase) that exists in Brassica plant tissue causing volatile isothiocyanates release. Currently existing literature data on the inactivation of myrosinase is insufficient in particular for use in the analysis of volatile and odor compounds in vegetables rich in glucosinolates. In this study, the impact of different metal salts in effective inactivation of enzyme activity was investigated by solid-phase microextraction (SPME) and GC/MS system in aqueous samples and kohlrabi matrix. A saturated solution of calcium chloride which is commonly used to stop enzyme activity in plant tissue inactivates the myrosinase-glucosinolate system. However, even without the participation of myrosinase, it changes the reaction pathway towards nitrile formation. The model experiment shows that optimum efficiency in inhibition of the enzyme system shows iron(III) ions, silver ions, and anhydride sodium sulfate resulting in no volatile products derived from glucosinolates. However, in the kohlrabi matrix, the strongest enzyme inhibition effect was observed for silver salt resulting in no volatile products, also both anhydrous Na2SO4 and saturated CaCl2 solution seem to be useful inhibitors in flavor studies.

A formal enantioselective total synthesis of the potent immunosuppressant FR901483 (1) has been accomplished. Our approach features the use of chiron 6 as the starting material, the application of the one-pot amide reductive bisalkylation method to construct the chiral aza-quaternary center (dr = 9:1), regio- and diastereoselective intramolecular aldol reaction to build the bridged ring, and ring closing metathesis to form the 3-pyrrolin-2-one ring.

Group 6 Metal Carbonyl Complexes Supported by a Bidentate PN Ligand: Syntheses, Characterization, and Catalytic Hydrogenation Activity

We report on the preparation of a series of phosphorusnitrogen donor ligand complexes [M(CO)(4)(PN)], where M = Cr, Mo, W and PN is 2-(diphenylphosphino)-ethylamine. The organometallic compounds were readily obtained upon reacting the respective metal hexacarbonyls with equimolar amounts of the pertinent ligand in the presence of tetraethylammonium bromide. The PN-ligated metal carbonyls were fully characterized by standard spectroscopic techniques and X-ray crystallography. The ability of the title compounds to function as homogeneous hydrogenation catalysts was probed in the reduction of acetophenone and benzaldehyde derivatives to yield the corresponding alcohols. The reaction setup was easily assembled by simply combining the components in the autoclave on the bench outside an inert-gas-operated glovebox system

Comparative study of fluxional processes at two different classes of eight-coordinate rhenium(V) polyhydride complexes

Two different structural types of dodecahedral rhenium(V) tetrahydride complexes were identified as capable of providing insight into a pseudorotational exchange of ligands at such complexes. One type of complex afforded an inequivalent set of NMR-active phosphorus atoms that occupy B sites in the rhenium coordination sphere along with four hydride ligands in the dodecahedral A sites. A second type of complex afforded the potential to inhibit the pseudorotational exchange of ligands at such complexes due to the presence of a chelating bidentate ligand. A pair of each type of complexes were studied by variable temperature NMR measurements and simulation of those measurements. The first type of complex exhibited pseudorotation of both the A site hydride ligands and the B site triphenylphosphine ligands. The first type of complexes also exhibited a pairwise exchange of the two inequivalent hydride ligands on the complexes. The second type of complex did not exhibit pseudorotational exchange of the A site hydride ligands, presumably due to the chelating bidentate ligand bound to rhenium. Instead, the A site hydride ligands of the second type of complex exhibited only exchange with the single B site hydride ligand through either a pairwise or a turnstile type of mechanism. Neither type of complex exhibited any direct intermolecular exchange of protons from the hydride ligand set with adventitious water from the solvent matrix. The value of Delta G(240)(double dagger) for each of the identified fluxional processes was close to 12 kcal/mol. The values of Delta S-double dagger for each fluxional process suggest that none of the processes are dissociative in nature.
