They stated further animal testing

"They are type of underappreciated medicinal agents," stated Bremer. "Our work shows the necessity to explore their potential further."
DNA 'barcoding' enables rapid testing of nanoparticles for therapeutic delivery
Using small snippets of DNA as "barcodes," scientific study has created a new way of quickly screening ale nanoparticles to selectively deliver therapeutic genes to a particular organs from the body. The process could accelerate the event and employ of gene therapies for such killers as cardiovascular disease, cancer and Parkinson's disease.
They also noted the study further demonstrates the necessity to explore metals for therapeutic uses. Metals aren't generally utilized in drug design due to concerns about toxicity and particular targeting when compared with organic compounds. However, several metal-based therapies already exist. For example, gold can be used in therapies for several cancers and rheumatoid arthritis symptoms, while other metal-based remedies are presently in numerous studies.

Next, they designed molecules known as ligands to do something as delivery vehicles for copper into neuronal cells, an important part of converting the therapeutic action of copper to biological systems. The TSRI team then sent their ligand-copper complexes for their study collaborators in the College of Wisconsin-Madison, who administered it to rodents. The compound extended the animals' lives, even if these were given lethal doses from the contaminant.
They stated further animal testing is required to determine optimal dosage, dosing frequency along with other factors. Janda stated numerous studies to demonstrate effectiveness cannot be carried out in humans because of botulinum neurotoxicity dangers. However, the security from the copper complex could be validated through other numerous studies already going ahead for various uses, he added.
If discovered to be safe, Bremer stated the copper therapeutic could give a more efficient therapy than existing methods to botox. Presently, botox sufferers get an anti-contaminant medicine that may inactivate the contaminant circulating within their system, therefore stopping further poisoning. However, the anti-contaminant cannot reverse preexisting paralysis since the contaminant functions inside cells. Consequently, disease recovery could be slow, and paralysis might take days or several weeks to put on off.
"The anti-contaminant is antibody-based, meaning it just works outdoors cells," stated Janda. "This latest therapy can readily enter cells where it may attack the etiological agent, a protease, which accounts for paralysis seen in the neurotoxin."
