Prodigiosenes conjugated to tamoxifen and estradiol

We report the synthesis of the first click-appended prodigiosene conjugates. Four prodigiosene conjugates of estradiol functionalised at the 7alpha-position were prepared, as were three prodigiosene conjugates of tamoxifen. The coupling between a prodigiosene and an 11-hydroxy estradiol derivative via an ether linkage was investigated, as was the 11- and 7-functionalisation of the estradiol core. The robustness of estradiol protecting groups was severely challenged by reactions typically used to equip such frameworks for 11- and 7-functionalisation. Specifically, and important to synthesis involving estradiol, TBS, TMS and THP are not useful protecting groups for the functionalisation of this core. When the chemical features of the therapeutic agent limit the choice of protecting group (in this case, prodigiosenes bearing aryl, NH, alkenyl and ester groups), click chemistry becomes an attractive synthetic strategy. The anti-cancer activity of the seven click prodigiosene conjugates was evaluated.

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.
