Two series of diorganotin(IV) complexes with dihalogenobenzohydroxamate ligands were prepared and shown to exhibit in vitro cytotoxic activities towards human leukemic promyelocites HL-60, BGC-823, BEL-7402 andB cell lines which, in some cases, are identical to, or even higher than, that of cisplatin. The dependence of the cytotoxic activity on some factors was also studied. | |

Drug-Fe(II) complexes have been synthesized. Structures of the complexes have been investigated using spectroscopic technique. All the complexes exhibit higher antibacterial activity than parental compounds. The absorption titration for sperm herring DNA and gel electrophoresis for pBR322 DNA show interpretative binding and cleavage of DNA with drug-Fe(II) complexes. | |

The mono-arylpyridyl bromides are very usefuley intermediates that can be further functionalized to generate bioactive compounds. It is possible to obtain mono-arylation products of 3,5-dibromopyridine with high preferentiality and high yields by air- and moisture-stable palladacycle (catalyst II) catalyzed Suzuki reaction under the conditions of2CO3-toluene-methanol (4:1, v/v), reflux (75 °C), 5.6 equiv. of 3,5-dibromopyridine with the ratio (mono:bis) ranging from of 99:1 to 90:10. This new method could also be used to easily achieve 3-bromo-5-pyridylpyridine (3j) with pyridyl | |
