pladienolide derivative E7107

Definition / meaning of pladienolide derivative E7107

A synthetic urethane derivative of pladienolide D with potential antineoplastic activity. Pladienolide derivative E7107 is generated from the 12-membered macrolide pladienolide D, one of several macrolides derived from the bacterium Streptomyces platensis Mer-11107. This agent appears to bind to the 130-kDa subunit 3 (spliceosome-associated protein 130; SAP130) of the splicing factor 3b (SF3b), resulting in inhibition of pre-messenger RNA splicing and the arrest of cell-cycle progression. The splicing factor SF3b is a multiprotein complex integral to the accurate excision of introns from pre-messenger RNA; the subunit SAP130 associates with U2 snRNP and is recruited to prespliceosomal complexes.
