Procedures were developed for the preparation of the 2-, 3-, 4-, and 6-monosubstituted chloro and bromo 8-quinolinols which afforded greater yields and/or reduced the number of steps in the preparation. 100 MHz 1H-NMR spectra for the 12 possible monochloro and mono bromo analogues are given

Fluoroacetate And Fluorocitrate: Mechanism Of Action / Donald D. Clarke, Donald Dudley Clarke Phd

Chemistry Faculty Publications

The concept of lethal synthesis as suggested by Peters is reviewed in the light of the more recent work in this area. It is suggested that fluorocitrate is a "suicide" substrate for aconitase rather than a competitive inhibitor as originally suggested. The use of these substances to study glialneuronal relationships is considered


Evidence Of Steric Factors In The Fungitoxic Mechanism Of 8-Quinolinol And Its 5- And 7-Halogenated Analogues / Herman Gershon, Donald D. Clarke, And Muriel Gershon, Herman Gershon, Donald Dudley Clarke Phd, Muriel Gershon Jan 1991

Antifungal studies were made of mixtures of minimal inhibitory concentrations (MICs) of 8-quinolinol and its 5- and 7-halo analogues against six fungi: Aspergillus niger, A. oryzae, Trichoderma viride, Myrothecium verrucaria, Mucor cirinelloides, and Trichophyton mentagrophytes. Mixtures of 8-quinolinol with 5- or 7-fluoro-8-quinolinol and of 5- and 7-fluoro-8-quinolinol showed additive activity, and their respective toxicities were reversed by L-cysteine. These results suggested a common mechanism of activity for the three toxicants. Potentiation of the fungitoxicity of mixtures of 8-quinolinol and its 5- and 7-chloro, bromo, and iodo analogues, as well as mixtures of 5- and 7-chloro, 5- and 7-bromo, and 5- ...
