The Chemistry Behind SB525334: Properties of a Key TGF-beta Receptor I Inhibitor

Understanding the chemical profile of a pharmaceutical intermediate is fundamental to its effective use in research and development. SB525334, identified by CAS number 356559-20-1, is a complex organic molecule that serves as a potent TGF-β Receptor I (ALK5) inhibitor. A deep dive into its chemical properties reveals why it is such a valuable tool for scientists.

The molecular formula of SB525334 is C21H21N5, with a molecular weight of approximately 343.425 g/mol. This structure, featuring a quinoxaline core with tert-butyl and methyl-pyridine substituents, is designed for precise interaction with the ALK5 kinase domain. The compound's physical appearance is typically described as a yellow solid, with a melting point around 159 °C. Its stability is noted as being stable for two years from the date of purchase when stored correctly, typically at 2-8 °C.

From a chemical perspective, SB525334's selectivity for ALK5 over other related kinases like ALK2, ALK3, and ALK6 is a key feature. This selectivity translates to more focused research outcomes when studying the TGF-beta signaling pathway. The compound's solubility, for instance, in DMSO (≥20mg/mL), is critical for preparing solutions for various experimental setups. Its acidity factor (pKa) of 10.24±0.10 (predicted) also provides insights into its behavior in different chemical environments.
