Characterization of isoquinolin alkaloids from Fumaria agraria and evaluation of their antiproliferative activity against human breast cancer cell lines

Fumaria agraria (Fumariaceae) is an annual plant used traditionally in Algeria for various medicinal purposes. Alkaloids extracts from areal parts were subjected to solvent fractionation and GCMS analysis. Rates of alkaloids recorded were respectively of 700 mg/100 g of Dry Weight of total alkaloids ?TA?, 400 mg/100 g DWof neutral fraction ?NF?, 40 mg/100 g DW of acid fraction ?AF? and 250 mg/100 g DWof the basic fraction ?BF?. Protopine was found to be the most potent alkaloid of the total extract (41.55%). Fractionation showed that Protopine was found essentially in the BF fraction (60.7%). Antiproliferative activities of total alkaloids extract and BF fraction were assessed on MCF-7 and MDAMB- 231 breast cancer and MCF10A mammary normal cell lines, by trypan blue exclusion essay. Both TA extract and BF fraction showed potent antiproliferative activities against MCF-7 breast cancer cells in varying degrees with respective IC50 of 47.8 ¡À 1.8 mug/ml and 17.6 ¡À 0.4 muM, without cell death induction but no impact was observed on normal MCF-10A cell growth. MCF7 Cell line was most sensitive (IC50 of 17,6 ¡À 0,4muM) to BF fraction effect than MDAMB-231 one (IC50 of 36,4 ¡À 0,6muM). Isoquinolein alkaloids of Fumaria agraria and specially the fraction which contain Protopine showed potent antiproliferative activity against breast cancer cells.

Polybenzimidazole (PBI)-functionalized silica nanoparticles modified PBI nanocomposite membranes for proton exchange membranes fuel cells

Polybenzimidazole (PBI) has been chemically bonded to silica nanoparticles (SNPs) through an ozone-mediated process using N-(p-carboxyphenyl)maleimide (pCPM) functionalized SNPs (SNP-pCPM) as precursors, to enhance the interfacial compatibility between SNPs and PBI in PBI/SNP nanocomposites. The PBI-functionalized SNPs (SNP-PBI) have been well characterized and used as inorganic nanofillers for preparation of PBI/SNP-PBI membranes for fuel cells. Addition of PBI-SNP to PBI membranes enhances their thermal and mechanical properties as well as decreases their phosphoric acid uptakes. For the PBI/SNP-PBI membrane with 10wt% of SNP-PBI, it shows a proton conductivity of about 50mScm-1 at 160C, which is 25% higher compared to the pristine PBI membrane. Consequently, the PBI/SNP-PBI membrane demonstrates a maximum power density of 650mWcm-2 in a single cell test, compared to the value of 530mWcm-2 read from the test for pristine PBI membrane.

Solvent dependent energy transfer of N-bridged naphthalimide- bisindolymaleimide fluorescent dyes

Double build-in chromophores, naphthalimide (NIM) and bisindolymaleimide (BIM), were synthesized and characterized. Absorption and emission properties of double chromophores dye were fully investigated in various solvents. The priority of through bond energy transfer (TBET) to NTM or BIM is solvent dependent. There appears large different emission wavelength change in CHCl 3 and DMF with alkyl attached to BIM. However, the product of cyclohexyl substitution leads to a different emission behavior, which is non-sensitivity to solvent polarity. Quantum chemical calculation for the molecular orbital reveals that intramolecular charge transfer (ICT) is the key factor for their different opto-electronic properties.

The Pd-catalyzed C-H alkylation of ortho -methyl-substituted aromatic amides with maleimide occurs preferentially at the ortho -methyl C-H bond over the ortho -C-H bond

The reaction of ortho-methyl-substituted aromatic amides with maleimides in the presence of Pd(OAc)2 and AgOAc results in C-H alkylation at the ortho-methyl C-H bond. DFT calculations indicate that the formation of a five-membered palladacycle is a kinetically favorable step, but the insertion of the maleimide into the six-membered palladacycle is energetically favored.

Ruthenium catalyzed decarbonylative arylation at sp3 carbon centers in pyrrolidine and piperidine heterocycles

This paper describes the development of a new catalytic transformation, the ruthenium-catalyzed decarbonylative arylation of cyclic 2-amino esters, which replaces the ester group with an aryl ring at the sp3 carbon center. For example, proline ester amidine 1 is converted to 2-arylpyrrolidine 3 in the presence of arylboronic acids or esters as arene donors and Ru 3(CO)12 as the catalyst. This process provides a rapid access to a variety of 2-arylpyrrolidines and piperidines from commercially available proline, hydroxyproline, and pipecolinate esters. The examination of the substrate scope also showed that many arene boronic acids and boronate esters serve as coupling partners. The high chemoselectivity of this process was demonstrated and ascribed to the significant rate difference between the decarbonylative arylation and the C-H arylation. The decarbonylative arylation complements the C-H arylation, since the latter process lacks control over the extent of functionalization, affording a mixture of mono- and bis-arylpyrrolidines. When applied in tandem, these two processes provide 2,5-diarylpyrrolidines in two steps from the corresponding proline esters. It was also demonstrated that the required amidine or iminocarbamate directing group fulfills two major functions: first, it is essential for the ester activation step, which occurs via the coordination-assisted metal insertion into the acyl C-O bond; second, it facilitates the decarbonylation, via the stabilization of a metallacycle intermediate, assuring the formation of the 2-arylated products instead of the corresponding ketones observed before by others.
