Metabolite identification methods

Metabolite identification is an important research direction in the field of biomedicine. Through the detection and analysis of metabolites in organisms, we can understand the metabolic status of organisms and the occurrence and development process of diseases, and provide strong support for disease diagnosis and treatment. The MetID team of Medicilon is composed of experienced scientists. We provide fast and reliable in vivo and in vitro MetID and reactive metabolite capture services. We also support new drug screening and domestic and oversees IND filings. Since the establishment of MetID team, Medicilon has successfully completed multiple different types of research projects for clients, including challenging peptide MetID research.

The following are some common methods for metabolite identification:

1. High performance liquid chromatography (HPLC): It can separate and detect small molecule metabolites in biological samples, and is often used for the detection of metabolites such as amino acids, organic acids, and fatty acids.

2. Mass spectrometry (MS): It can identify metabolites with larger molecular weights in biological samples, such as peptides, proteins, nucleic acids, etc., and is often used in proteomics and metabolomics research.

3. Nuclear Magnetic Resonance (NMR): It can analyze the structure of organic molecules in biological samples and is often used for the structural identification of metabolites and the study of metabolic processes.

4. Gene knockout/transgenic technology: Through gene knockout or transgenic technology, the impact of specific genes on the synthesis and decomposition process of metabolites is studied.

5. Isotope labeling technology: By injecting isotope-labeled substances into organisms, the synthesis and decomposition process of metabolites in organisms can be studied.

6. Bioinformatics methods: Through bioinformatics methods, a large amount of genome and metabolome data are integrated and analyzed to understand the synthesis and decomposition processes of metabolites in organisms and the functions of related genes.

What is preclinical testing?

In the process of preclinical testing of a compound or biological agent into a drug, the compound involved must go through the testing phase. First, we need to identify potential targets that can treat the disease. Then, a variety of compounds or preparations are screened out. Any compound that has shown potential as a drug for the treatment of this disease needs to be tested for toxicity before clinical testing to reduce the possibility of injury. preclinical testing What is the basis of preclinical testing? According to US Food and Drug Administration (FDA) regulations, a series of tests are required before a new drug is approved for use. In the first stage, basic research determines a hypothetical target for the treatment of a certain disease, and then screens small molecules or biological compounds to discover any substance with the potential to treat the disease. Then, a preclinical research phase followed, before which, as described above, the potential toxicity of the compou

Inventory of the three major in vitro pharmacokinetic research methods

The metabolic properties of a compound are an essential factor in whether or not it can be used as a drug in the clinical setting, so pharmacokinetic studies of newly synthesized compounds are required in drug development. In vitro incubation with liver microsomes, recombinant CYP450 enzyme lines, and in vitro incubation with hepatocytes are some of the more common in vitro drug metabolism methods. 1. In vitro incubation method with liver microsomes The metabolic stability and metabolic phenotypes of candidate compounds in different species of liver microsomes are good predictors of the metabolic properties of compounds in vivo. They are practical tools for evaluating candidate compounds in the pre-development phase of drug development. Liver microsomes include rat liver microsomes, human liver microsomes, canine liver microsomes, monkey liver microsomes, and mouse liver microsomes. In in vitro incubation of the liver, microsomes are the "gold standard" for in vitro d

Novel Parkinson’s Therapies Possible with New Mouse Model

Parkinson's disease (PD) is a neurodegenerative disorder that is marked by the accumulation of the protein, α-synuclein (αS), into clumps known as Lewy bodies, which diminish neural health. Now, researchers from Brigham and Women's Hospital (BWH) report the development of a mouse model to induce PD-like αS aggregation, leading to resting tremor and abnormal movement control. The mouse responds to L-DOPA, similarly to patients with PD. The team's study (“Abrogating Native α-Synuclein Tetramers in Mice Causes a L-DOPA-Responsive Motor Syndrome Closely Resembling Parkinson’s Disease”) on the use of this transgenic mouse model appears in Neuron . “α-Synuclein (αS) regulates vesicle exocytosis but forms insoluble deposits in PD. Developing disease-modifying therapies requires animal models that reproduce cardinal features of PD. We recently described a previously unrecognized physiological form of αS, α-helical tetramers, and showed that familial PD-causing missense mutati
