    • Alternaria toxins in South African sunflower seeds: cooperative study 

      Hickert, Sebastian; Flett, Bradley; Hermes, Lena; Marques, Lucas Maciel Mauriz; Focke, Christine (Springer, 2017)
      Sunflower seed samples (N = 80) from different sunflower cultivars originating from different localities in South Africa were analyzed for 15 toxins produced by fungi of the genus Alternaria by means of a simple one-step ...
    • In vitro antioxidant, antimutagenic and genoprotective activity of Rosa roxburghii fruit extract 

      Van der Westhuizen, Francois H.; Janse van Rensburg, Catharina S.; Rautenbach, George S.; Loots, Du Toit; Huysamen, Cristal; Louw, Roan; Pretorius, Pieter J.; Erasmus, Elardus; Marnewick, Jeanine L.; Van der Westhuizen, Francois H.; Janse van Rensburg, Catharina S.; Rautenbach, George S.; Loots, Du Toit; Huysamen, Cristal; Louw, Roan; Pretorius, Pieter J.; Erasmus, Elardus; Marnewick, Jeanine L. (Wiley, 2008)
      The antioxidant properties of the fruit of the Rosa roxburghii (RR) plant have been associated with several putative health promoting effects. The possible cytotoxic, mutagenic/antimutagenic and genotoxic effects of RR ...
    • Pathogenic features of heterotrophic plate count bacteria from drinking-water boreholes 

      Horn, Suranie; Pieters, Rialet; Bezuidenhout, Carlos (IWA Publishing, 2016)
      Evidence suggests that heterotrophic plate count (HPC) bacteria may be hazardous to humans with weakened health. We investigated the pathogenic potential of HPC bacteria from untreated borehole water, consumed by humans, ...
    • Synthesis and in vitro antimalarial activity of a series of bisquinoline and bispyrrolo[1,2a]quinoxaline compounds 

      Van Heerden, Lezanne; Cloete, Theunis T.; Breytenbach, J. Wilma; Breytenbach, Jaco C.; N'Da, David D.; De Kock, Carmen; Smith, Peter J.; Van Heerden, Lezanne; Cloete, Theunis T.; Breytenbach, J. Wilma; Breytenbach, Jaco C.; N'Da, David D.; De Kock, Carmen; Smith, Peter J. (Elsevier, 2012)
      Series of bisquinolines 4e15 and bispyrrolo[1,2a]quinoxalines 16e20 containing various polyamine linkers were synthesized. The aqueous solubility and distribution coefficient were experimentally determined. The compounds ...
    • Synthesis and in vitro biological activities of ferrocenyl-chalcone amides 

      Smit, Frans J.; Bezuidenhout, Jaco J.; Bezuidenhout, Carlos C.; N'Da, David D. (Springer, 2016)
      A series of aminoferrocenyl–chalcone amides 11–19 were synthesized through condensation of a carboxylic acid-functionalized chalcone 10 with ferrocenylamines, using 1,1′-carbonyldiimidazole as the coupling agent. The ...
