Resumen
Desarrollamos un enfoque de cribado de espectrometría de masas de selección de afinidad proteica enantioselectiva (E-ASMS) para descubrir uniones débiles para dianas proteicas desafiantes. Este método identifica ligandos quirales selectivos con alto rendimiento y sensibilidad.
Sus antecedentes:
- La identificación de ligandos selectivos para dianas proteicas desafiantes sigue siendo un obstáculo importante en el descubrimiento de fármacos.
- Las uniones débiles y la enantioselectividad son factores críticos que a menudo se pasan por alto en los métodos de cribado tradicionales.
Conclusiones:
- E-ASMS es un método potente, de alto rendimiento y sensible para identificar ligandos débiles y selectivos.
- El enfoque permite el descubrimiento de ligandos para dianas proteicas previamente intratables.
- E-ASMS proporciona confirmación ortogonal y conocimientos mecanicistas sobre la unión enantioselectiva.

01:33Peptide Identification Using Tandem Mass Spectrometry
8.1K
Tandem mass spectrometry, also known as MS/MS or MS2, is an analytical technique that employs two mass analyzers. Essentially it is a series of mass spectrometers that helps isolate a particular biomolecule and then helps study its chemical properties.
This technique helps gather information regarding the protein from which the peptide was obtained and to study the peptides’ amino acid sequence. Identifying peptides from a complex mixture is an important component of the growing field of...

2.2K
Tandem mass spectrometry is a technique that uses multiple mass analyzers in series to obtain a higher selectivity and reduce chemical noise during analyte detection. Instruments with multiple analyzers separated by an interaction cell enable secondary fragmentation and selected study of the fragment ions.Secondary fragmentations occur in the interaction cell and can be induced by various factors. Fragmentation induced by collision with inert gases, such as N2, Ar, He, etc., is called...

6.4K
Mass spectrometry is a powerful characterization technique that can identify and separate a wide variety of compounds ranging from chemical to biological entities, based on their mass-to-charge ratio (m/z). The instruments that allow this detection, known as mass spectrometers, have three components: an ion source, a mass analyzer, and a detector. These spectrometers differ based on the nature of their ion source and analyzers.Matrix-assisted laser desorption ionization (MALDI) is a commonly...
