  • PubMed Abstract: 

    The formation of amorphous protein aggregates containing human superoxide dismutase (hSOD1) is thought to be involved in amyotrophic lateral sclerosis onset. cis -Platin inhibits the oligomerization of apo hSOD1, but its toxicity precludes any possible use in therapy. Herein, we propose a less toxic platinum complex, namely oxa/ cis -platin, as hSOD1 antiaggregation lead compound. Oxa/ cis -platin is able to interact with hSOD1 in the disulfide oxidized apo form by binding cysteine 111 (Cys111). The mild neurotoxic phenomena induced in vitro and in vivo by oxa/ cis -platin can be successfully reverted by using lypoyl derivatives, which do not interfere with the antiaggregation properties of the platin derivative.
