Pladienolide B 

Pladienolide B is a potent cancer cell growth inhibitor that targets the SF3B1 subunit of the spliceosome. Pladienolide B exerts antitumor activities mediated through the inhibition of pre-mRNA splicing. Pladienolide B induces apoptosis^[1][2][3].

Pladienolide B (0.1-2 nM; 24-72 hours) inhibits human cervical carcinoma cells viability^[3].
Pladienolide B (0.1-2 nM; 24-48 hours) reduces SF3b1 expression in human cervical carcinoma cells^[3].
Pladienolide B induces (0.1-2 nM; 24 hours) cell cycle arrest and apoptosis^[3].

Pladienolide B (2.5-10 mg/kg; i.v.; daily for 5 days) has strong antitumor activities^[4].
