  • Divergent Total Synthesis of the Antimitotic Agent Leiodermatolide
    作者:Jens Willwacher、Nina Kausch-Busies、Alois Fürstner
    DOI:10.1002/anie.201206670
    日期:2012.11.26
    Subtle but distinctive: The stereostructure of the biologically highly promising antimitotic agent leiodermatolide was uncertain. A short, efficient, and flexible total synthesis based on ring‐closing alkyne metathesis as the key step has now solved the puzzle. Subtle differences in the 1H NMR spectra of the structure shown and the conceivable isomer proved invaluable for the assignment.
    微妙但与众不同:生物学上很有前途的抗有丝分裂剂leiodermatolide的立体结构尚不确定。以开环炔烃复分解为关键步骤的短而有效且灵活的全合成方法现已解决了这个难题。所示结构和可能的异构体在1 H NMR光谱中的细微差异证明对于该赋值是无价的。
  • Synthesis, Molecular Editing, and Biological Assessment of the Potent Cytotoxin Leiodermatolide
    作者:Damien Mailhol、Jens Willwacher、Nina Kausch-Busies、Elizabeth E. Rubitski、Zhanna Sobol、Maik Schuler、My-Hanh Lam、Sylvia Musto、Frank Loganzo、Andreas Maderna、Alois Fürstner
    DOI:10.1021/ja508846g
    日期:2014.11.5
    It was by way of total synthesis that the issues concerning the stereostructure of leiodermatolide (1) have recently been solved; with the target now being unambiguously defined, the mission of synthesis changes as to secure a meaningful supply of this exceedingly scarce natural product derived from a deep-sea sponge. To this end, a scalable route of 19 steps (longest linear sequence) has been developed, which features a catalytic asymmetric propargylation of a highly enolizable beta-keto-lactone, a ring closing alkyne metathesis and a modified Stille coupling as the key transformations. Deliberate digression from this robust blueprint brought a first set of analogues into reach, which allowed the lead qualities of 1 to be assessed. The acquired biodata show that 1 is a potent cytotoxin in human tumor cell proliferation assays, distinguished by GI(50) values in the =3 nM range even for cell lines expressing the Pgp efflux transporter. Studies with human U2OS cells revealed that 1 causes mitotic arrest, micronucleus induction, centrosome amplification and tubulin disruption, even though no evidence for direct tubulin binding has been found in cell-free assays; moreover, the compound does not seem to act through kinase inhibition. Indirect evidence points at centrosome declustering as a possible mechanism of action, which provides a potentially rewarding outlook in that centrosome declustering agents hold promise of being inherently selective for malignant over healthy human tissue.
