Application

Madrasin has been used as a spliceosome inhibitor to inhibit pre-mRNA processing in 3T3-L1 cells.

Biochem/physiol Actions

Madrasin is a potent and cell penetrant splicing inhibitor that interferes with the early stages of spliceosome assembly. Madrasin stalls spliceosome assembly at the A complex.
Madrasin is considered toxic to the cell at a higher concentration. At its minimal concentration, madrasin is known to induce subnuclear protein localization and cause cell cycle arrest.

Eukaryotic pre-mRNA splicing is an essential step in gene expression for all genes that contain introns. In contrast to transcription and translation, few well characterized chemical inhibitors are available with which to dissect the splicing process, particularly in cells. Therefore
