Optimization of Antitumor Modulators of Pre-mRNA Splicing
摘要:
The spliceosome regulates pre-mRNA splicing, which is a critical process in normal mammalian cells. Recently, recurrent mutations in numerous spliceosomal proteins have been associated with a number of cancers. Previously, natural product antitumor agents have been shown to interact with one of the proteins that is subject to recurrent mutations (SF3B1). We report the optimization of a class of tumor-selective spliceosome modulators that demonstrate significant in vivo antitumor activity. This optimization culminated in the discovery of sudemycin D6, which shows potent cytotoxic activity in the melanoma line SK-MEL-2 (IC50 = 39 nM) and other tumor cell lines, including JeKo-1 (IC50 = 22 nM), He La (IC50 = SO nM), and SK-N-AS (IC50 = 81 nM). We also report improved processes for the synthesis of these compounds. Our work supports the idea that sudemycin D6 is worthy of further investigation as a novel preclinical anticancer agent with application in the treatment of numerous human cancers.

We report the design and highly enantioselective synthesis of a potent analogue of the spliceosome inhibitor FR901464, based on a non-naturalproduct scaffold. The design of this compound was facilitated by a pharmacophore hypothesis that assumed key interaction types that are common to FR901464 and an otherwise unrelated naturalproduct (pladienolide). The synthesis allows for the preparation of numerous
