产品描述

Spliceosomes mediate the processing of pre-mRNA into mature mRNA.[1],[2] Each spliceosome is a multiunit complex containing several proteins and RNA molecules that work in unison to repeatedly cleave and rejoin segments of mRNA.[1],[3] Pladienolide B is a macrocyclic lactone that selectively binds splicing factor 3b and inhibits mRNA splicing.[4],[5] Through this action, pladienolide B potently blocks the growth of proliferating cells with mean IC50 values of 1.6 nM for six gastric cancer cell lines.[6],[7] In xenograft tumors generated in mice using human cancer cells, pladienolide B blocks mRNA splicing and induces apoptosis, clearing tumors within two weeks after treatment.[7]
