Flow Cytometric Analysis of the Influence of Myosmine on the Cell Cycle

Myosmine (3-(1-pyrrolin-2-yl)pyridine) is an alkaloid found in tobacco as well as various staple foods, fruits and vegetables. Myosmine has recently been suspected to be a tobacco-independent carcinogenic source. Using cell flow cytometry, we have examined the influence of myosmine on the cell cycle of murine erythroleukemia (MEL) cells in vitro and have compared this with its effects on murine bone marrow cells in vivo. Myosmine at low concentrations inhibited cell proliferation dose dependently; while at concentrations close to 300 mu mol dm(-3) it acted in a cytostatic fashion, that is, it increased the percentage of cells in the S and G2/M phases. At doses of 350-400 mu mol dm(-3) myosmine induced apoptosis and the hypoploid fraction. In vivo intraperitoneal injection of mice with 100 mg/kg of myosmine resulted in a statistically significant increase in the percentage of cells in S phase; i.e. from 13.75 to 18.22%. The percentage of bone marrow cells in the G2/M phase increased from 6.79 to 8.93 % in treated mice compared to controls. All of these results are in agreement with the hypothesis that myosmine possesses genotoxic potential. (doi: 10.5562/cca1767)

Synthesis and reactivity of (1S)-N-(1-phenylethyl)maleimide towards nucleophiles: an application to preparation of chiral pyrroloisothiochroman and pyrrolobenzo[d]thiepine based on pi-cationic cyclization

Chiral pyrroloisothiochroman and pyrrolo[d]thiepine were obtained efficiently in four steps from N-alkylated maleimides via, successively, sulfurization, regioselective reduction followed by pi -cationic cyclination of the N-acyliminium ion intermediates. These latter, in addition, led to conjugate enamides as a consequence of the dehydration reaction. (C) 2001 Elsevier Science Ltd. All rights reserved.

Detection of CH3C3N in Titan’s Atmosphere

Titan harbors a dense, organic-rich atmosphere primarily composed of N-2 and CH4, with lesser amounts of hydrocarbons and nitrogen-bearing species. As a result of high-sensitivity observations by the Atacama Large Millimeter/submillimeter Array (ALMA) in Band 6 (similar to 230-272 GHz), we obtained the first spectroscopic detection of CH3C3N (methylcyanoacetylene or cyanopropyne) in Titan’s atmosphere through the observation of seven transitions in the J = 64 -> 63 and J = 62 -> 61 rotational bands. The presence of CH3C3N on Titan was suggested by the Cassini Ion and Neutral Mass Spectrometer detection of its protonated form: C4H3NH+, but the atmospheric abundance of the associated (deprotonated) neutral product is not well constrained due to the lack of appropriate laboratory reaction data. Here, we derive the column density of CH3C3N to be (3.8-5.7).x.10(12) cm(-2) based on radiative transfer models sensitive to altitudes above 400 km Titan’s middle atmosphere. When compared with laboratory and photochemical model results, the detection of methylcyanoacetylene provides important constraints for the determination of the associated production pathways (such as those involving CN, CCN, and hydrocarbons), and reaction rate coefficients. These results also further demonstrate the importance of ALMA and (sub)millimeter spectroscopy for future investigations of Titan’s organic inventory and atmospheric chemistry, as CH3C3N marks the heaviest polar molecule detected spectroscopically in Titan’s atmosphere to date.

Conversion of Some 2(3H)-Furanones into Pyrrolinotriazine and Oxazolopyrimidine Derivatives

2(3H)-Furanones 1 were utilized for the construction of pyrrolinotriazine and oxazolopyrimidine derivatives 4 and 9. Thus, 1 reacted with glycine in ethanol at 70 degrees C to give the acids 2, which were cyclized into the pyrrolin-5-one derivatives 3 by the action of HCl/AcOH. The later compounds 3 were also obtained by refluxing the furanones 1 with glycine in glacial AcOH for 10 h. The carboxy functionality in 3 was used for the construction of a triazinone ring by treatment with thionyl chloride followed by refluxing the acid chloride with hydrazine in ethanol. The conversion of the furanones 1 into the oxazolopyrimidine derivatives 9 involved the following steps: (i) ring opening of the lactone ring with hydrazine hydrate to give the acid hydrazides 5, (ii) conversion of the hydrazides 5 into the corresponding acyl azides 6 by action of NaNO2/AcOH, (iv) base-catalyzed decomposition of the azides in the presence of glycine, (v) ring closure of the urea derivatives 7 into the pyrimidine derivatives 8, and finally (vi) condensing 8 with benzaldehyde in the presence of NaOAc/AcOH mixture.

Covalent Modification of Cytochrome c by Reactive Metabolites of Furan

Metabolism of the hepatotoxicant furan leads to protein adduct formation in the target organ. The initial bioactivation step involves cytochrome P450-catalyzed oxidation of furan, generating cis-2-butene-1,4-dial (BDA). BDA reacts with lysine to form pyrrolin-2-one adducts. Metabolic studies indicate that BDA also reacts with glutathione (GSH) to generate 2-(S-glutathionyl)butanedial (GSH-BDA), which then reacts with lysine to form GSH-BDA-lysine cross-links. To explore the relative reactivity of these two reactive intermediates, cytochrome c was reacted with BDA in the presence and absence of GSH. As judged by MALDI-TOF mass spectrometry, BDA reacts extensively with cytochrome c to form adducts that add 66 Da to the protein, consistent. with the formation of pyrrolinone adducts. Addition of GSH to the reaction mixture reduced the overall extent of adduct formation. The mass of the adducted protein was shifted by 355 Da as expected for GSH-BDA-protein cross-link formation. LC-MS/MS analysis of the tryptic digests of the alkylated protein indicated that the majority of adducts occurred on lysine residues, with BDA reacting less selectively than GSH-BDA. Both types of adducts may contribute to the toxic effects of furan.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. 13676-54-5, you can contact me at any time and look forward to more communication. Safety of Bismaleimide.
