    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.

  • Intramolecular nitrile oxide cycloaddition on chiral olefins: a stereocontrolled approach to β-ketol precursors
    作者:Rita Annunziata、Mauro Cinquini、Franco Cozzi、Giulio Dondio、Laura Raimondi
    DOI:10.1016/s0040-4020(01)86823-x
    日期:——
    The intramolecular nitrile oxide cycloaddition reaction on chiral (E) and (Z) olefins featuring a sulphur atom along the carbon chain connecting dipole and dipolarophile occurs with poor to excellent anti stereoselectivity, which is mainly affected by the substitutents at the allylic stereocenter. The possibility of converting the cycloadducts into stereoisomerically pure β-ketols has been established

    A novel type of ketene-Claisen rearrangement in which the precursor of the rearrangement is generated in situ by reaction of optically active allyl thioethers with dichloroketene is described. A characteristic feature of this rearrangement is the excellent chemoselectivity in favor of allyl thioethers vs. allyl ethers, i.e., exclusive chirality transfer of the allylic sulfur moiety is observed with

    allylic alcohols have been prepared and submitted to a Mitsunobu reaction with dithioacetic acid. Allyl dithioesters were deprotonated by LDA at −30°C and resulting enethiolates were quenched with iodomethane to afford quantitatively S-allyl ketenedithioacetals. These precursors undergo a thio-Claisen rearrangement under smooth conditions: room temperature or heating at 101°C. The diastereoselectivity of

    The cyclization of δ-acetoxy-O-allyl- and ϵ-acetoxy-O-homoallyl-trichloroacetimidates to 4-vinyloxazolines and a 4-vinyldihydrooxazine has been efficiently achieved by olefin aminopalladation–β-heteroatom elimination. (Z)-Allylic imidates bearing a secondary δ-acetoxy group underwent PdII-catalysed cyclization to give the E isomers of 4-vinyloxazolines selectively and gave no Overman rearrangement
