SAP 155 Activators

The chemical class of SF3B1 Activators includes compounds that can indirectly influence the activity of SF3B1 through their effects on splicing factors, RNA processing, and related cellular signaling pathways. These compounds do not directly activate SF3B1; instead, they modulate cellular environments or pathways that could impact SF3B1's functional role in RNA splicing.

Compounds like Pladienolide B, Spliceostatin A, Meayamycin, Sudemycin D6, and E7107 target components of the spliceosome complex, potentially affecting SF3B1's activity in RNA splicing. Isoginkgetin and histone deacetylase inhibitors like Trichostatin A, Vorinostat, and Romidepsin may affect gene expression patterns, potentially impacting the splicing activities of SF3B1. Proteasome inhibitors like Bortezomib and MG-132 could indirectly influence the dynamics of splicing factors, including SF3B1, by affecting protein turnover and cellular stress responses.
