Thailanstatin D, an analogue of Thailanstatin A, inhibits AR-V7 gene splicing by disrupting the interaction between U2AF65 and SAP155, hindering their binding to the polypyrimidine tract situated between the branch point and the 3' splice site. This compound displays potent tumor inhibitory properties in human castration-resistant prostate cancer (CRPC) xenografts, resulting in cellular apoptosis.
Telaglenastat (CB-839) hydrochloride is a first-in-class, reversible, and orally active inhibitor of glutaminase 1 (GLS1). It selectively inhibits the splice variants of GLS1, specifically KGA (kidney-type glutaminase) and GAC (glutaminase C), as compared to GLS2. Telaglenastat hydrochloride has an IC50 of 23 nM for endogenous glutaminase in mouse kidney and 28 nM in the brain. In addition, it induces autophagy and exhibits antitumor activity.
Vercirnon (GSK1605786A) sodium is an orally bioavailable, selective, and potent antagonist of CCR9 . Vercirnon sodium inhibits CCR9-mediated Ca 2+ mobilization and chemotaxis on Molt-4 cells with IC 50 values of 5.4 and 3.4 nM, respectively. Vercirnon sodium is selective for CCR9 over CCR1-12 and CX3CR1-7 (IC 50 s>10 μM for all). Vercirnon sodium is an equipotent inhibitor of CCL25-directed chemotaxis of both splice forms of CCR9 (CCR9A and CCR9B) with IC 50 values of 2.8 and 2.6 nM, respectively.
Minnelide is an effective therapy against pancreatic cancer. Minnelide Inhibits Androgen Dependent, Castration Resistant Prostate Cancer Growth by Decreasing Expression of Androgen Receptor Full Length and Splice Variants. Minnelide reduced tumor volume in multiple models of pancreatic cancer. Minnelide was a more effective drug against pancreatic cancer models. It effectively reduced tumor burden and tumor related morbidity in different unique but complementary mouse models. It reduced metastatic spread and increased survival in the different models as well.
NSC 194308, an enhancer of U2AF2-RNA complexes, promotes the association of the U2AF1-U2AF2-SF1-splice site RNA complex by targeting a site between U2AF2 RNA recognition motifs (RRM1 and RRM2). It inhibits pre-mRNA splicing by stalling spliceosome assembly at the stage where U2AF recruits U2 snRNP to the branchpoint. Additionally, NSC 194308 strengthens the binding of pre-mRNA to U2AF2, selectively inducing cell death in leukemia cell lines with spliceosome mutations [1].
