SiDMAP Launches a Metabolomics Service for Early Detection of Drug-Induced Liver and Kidney Toxicity
News Oct 24, 2008
Using its proprietary metabolomics technology platform, SiDMAP is able to monitor changes in vital metabolite fluxes in response to drug treatment to quickly determine organ toxicity before structural or morphological damage occurs.
With recent advances in drug discovery, large numbers of potential new drugs have been identified. Yet, a big obstacle that remains in drug discovery and development is the lack of a reliable way to screen these drug candidates to determine toxicity levels early enough in the process. Based on research performed by SiDMAP in collaboration with the Center for Metabolomics at the FDA National Center for Toxicological Research, SiDTox' now also includes a cost-effective and non-invasive test which promises to better enable pharmaceutical researchers to rapidly detect drug-induced toxicity prior to organ damage.
'Using non-invasive and non-emitting 13C glucose tracer, we are able to quantify synthesis and turnover of selected metabolites in real time in order to develop the necessary translational plasma, tissue and urine isotopomer profiles routinely applicable as toxicity biomarkers in humans,' commented Dr. Laszlo Boros, SiDMAP's Chief Scientific Advisor. 'Our tracer substrate approach utilizes the accurate assessment and quantification of cross-talk and flux alterations among physiologically vital substrate and product pools and their disruption to provide early indications of the presence and mechanisms of drug-induced toxicity, as seen in the FDA study involving valproic acid.'
Presently, drug toxicities, in general, are assessed by morphological markers of organ damage, proteomic and metabonomics methods and gene expression profiles. However, there remains a need for rapid markers to detect drug toxicity prior to irreversible organ damage.
Researchers say they have discovered a gene mutation that slows the metabolism of sugar in the gut, giving people who have the mutation a lower risk of diabetes, obesity, heart failure, and even death. The researchers say their finding could provide the basis for drug therapies that could mimic the workings of this gene mutation.
A computer-guided algorithm may help scientists find just the right spot to split a protein and then reassemble it to functionality, according to a new study. Researchers say this could be another step — perhaps even a dance step — toward using chemical and light signals to create new medical treatments and biosensors.READ MORE
