nRNP Inhibitors

nRNP inhibitors as a chemical class are not well-established, due to the lack of direct inhibitors that specifically target these proteins. However, the above list provides a snapshot of chemicals that can indirectly affect nRNP function through various pathways and processes. nRNPs are a diverse group of RNA-binding proteins that play key roles in post-transcriptional regulation of gene expression, including mRNA splicing, transport, stability, and translation. The mechanisms of action for the above chemicals range from disrupting the nuclear export of RNA (Leptomycin B), interfering with the spliceosome and its associated components (Pladienolide B, E7107, Sudemycin, Meayamycin B), to altering cellular conditions (Amiloride) or protein synthesis (Emetine, Rocaglamide, Silvestrol) that can indirectly impact nRNP function.

Many of these compounds affect the spliceosome, a complex molecular machine that is crucial for the correct splicing of pre-mRNA, a process in which nRNPs are intimately involved. For example, Pladienolide B and its derivatives bind to the spliceosome, potentially altering its function and, by extension, the role of nRNPs in RNA splicing. Other compounds, such as Amiloride, may not directly interact with nRNPs but can create cellular conditions that are unfavorable for nRNP function.
