Antitumour and antimicrobial properties of a series of triorganylsilyl( | |
-dialkylaminoethoxy)silanes synthesized were investigated. Their cytotoxicity was tested in vitro on two monolayer tumour cell lines: HT-1080 (human fibrosarcoma), MG-22A (mouse hepatoma), and normal mouse fibroblasts (NIH 3T3). Their antibacterial and antifungal activity was investigated against two Gram-positive, Bacillus cereus ATCC 11778 and Staphylococcus aureus ATCC 25923, two Gram-negative, Proteus mirabilis NCIM 2241 and E. coli ATCC 25922, and two fungi strains Candida tropicalis ATCC 4563 and Candida albicans ATCC 2091. On the basis of the biological activity data against tumour cell lines and all the test bacterial/fungal strains, it has been demonstrated that silylation stimulates the overall pharmacological potency appearance or enhancement.

Series of antibacterial/antifungal isatin-bearing sulphonamides and their cobalt (II), copper (II), nickel (II) and zinc (II) metal complexes have been synthesized and screened for in-vitro antibacterial activity against Bacillus cereus, Corynebacterium diphtheriae, Escherichia coli,lebsiella pneumoniae, Proteus mirabilis, Pseudomonas aeruginosa, Salmonella typhi, Shigilla dysentriae, and Staphylococcus aureus and, for in-vitro antifungal activity against Trichophyton schoenleinii, Candid glabrata, Pseudallescheria boydii, Candida albicans, Aspergillus niger, Microsporum canis and Trichophyton mentagrophytes. The brine shrimp bioassay was also carried out to study their in-vitro cytotoxic properties. | |

Speciation Analysis and Environment
Simulate methylation reaction of arsenic(III) with methyl iodide in an aquatic system (p 747-753)

Reaction mechanism of inorganic As(III) with methyl iodide is an oxidative carbonium-transfer process. The effects of pH and salinity on methylation may be explained from a thermodynamic point of view. Redox potential switch was important to methylation reaction in the aquatic environment. Methylation reaction had good correlation with first-order reactioninetics for both As(III) and methyl iodide. | |

The polymerization of methyl methacrylate catalyzed by bidentate phosphine molybdenum tetracarbonyl complexes has been studied. The activity of these catalysts depends on the length of the (CH2)n bridge of diphosphine ligand. | |
Synthesis of novel zirconium complexes bearing mono-Cp and tridentate Schiff base [ONO] ligands and their catalytic activities for olefin polymerization (p 758-765)

DOI: 10.1002/aoc.1124
A series of novel zirconium-complexes 1-6 bearing mono-Cp and tridentate Schiff base [ONO] ligands are prepared. The molecular structure of complex 1 is further confirmed by X-ray diffraction study. When activated by excess methylaluminoxane, complexes 1-6 exhibit high catalytic activities for ethylene polymerization. The influence of polymerization temperature on the activities of ethylene polymerization is investigated, and these complexes show high thermal stability. Complex 6 is also active for the copolymerization of ethylene and 1-hexene with low 1-hexene incorporation ability. | |

Two NHC-Pd(II) complexes syn-thesized from trans-cyclohexane-1,2-diamine were fairly effective in the NHC-Pd(II) complex/Cu co-catalyzed terminal alkyne homocoupling reaction to give the corresponding symmetrical 1,4-disubstituted 1,3-diynes in good yields under mild conditions. | |

A 0.1-0.2 µm Na A zeolite was successfully synthesized, using silatrane and alumatrane precursors via the sol-gel process, seeding and microwave techniques. The best condition for synthesizing the smallest size and the most homogeneous NaA zeolite is to use the composition of SiO2:Al2O3:3Na2O:410H2O with 3 wt% crystal seed at 80 °C microwave heating for 6 h. | |
