Anodic oxidation of the dye molecules, methylene blue, acid blue 25, reactive blue 2 and reactive blue 15 in chloride solution leads to colour destruction but UV and TOC data show that the oxidation reactions do not lead to complete destruction of th

Two pyridine analogues of the metal complexing region of the anticancer drug bleomycin and two related but deactivated prodrugs have been linked to a 2,6-diphenylpyridine derivative as a DNA binding unit. The 2,6-diphenylpyridine system is structural

An unexpected reaction of 1,5-bis(arylamino)-3-oxapentanes 4, 21 and 22 with diglycolyl dichloride gave 24-membered macrocyclic tetralactams 18, 23 and 24 respectively, in a reaction involving two molecules of each reactant (2:2 process). This was in

The synthesis of 2,6-disubstituted pyridines 10, 23, 27a–28b is reported. These compounds are expected to complex iron(II) and yield hydroxyl radicals by interaction of the aqueous complex with oxygen. In addition a second series of 2,6-disubstitut

Prodrugs bioreductively activated to bleomycin analogues are reported. The production of hydroxyl radicals in the presence of FE(II) and dioxygen by both the prodrugs and the activated products are determined and their in vitro cytotoxicity measured.

The radical cations of indol-3-ylacetic acid and derivatives were found to eliminate CO2 to yield skatolyl radicals with rates in the range ca. 102 to >105 s-1, strongly dependent on substitution. For the radical cations substituted at nitrogen, the

Improved routes to the quinoxalinone acid chloride 1 and the 3-methyl-quinoxalinone 21 are described. These intermediates are used to obtain the fluoroionophores 15–19 and 27–29, respectively. The effects of the complexation of metal ions by the
