  Absolute stereostructure and total synthesis of leptomycin B

  摘要：

  The absolute stereostructure of leptomycin B, an antitumor antibiotic and inhibitor of nuclear protein export, was firstly presumed as 1 having 4S, 5R, 10R, 16R, 18S, 19R, 20S on the basis of NMR comparison with callystatin A (2) and then 1 was asymmetrically synthesized. The synthesized leptomycin B (I) was found identical with the authentic sample in HPLC and CD comparison as well as in other respects. This structural elucidation of the absolute stereostructure and total synthesis are the first example;among the leptomycin family as Streptomyces metabolites. (C) 1998 Elsevier Science Ltd.

  Bioassay-guided separation by use of the fission yeast expressing NES of Rev, a HIV-1 viral regulatory protein, resulted in isolation of valtrate (1) as a new Rev-transport inhibitor from the nucleus to cytoplasm from Valerianae Radix. Valtrate (1) also inhibited the p-24 production of HIV-1 virus without showing any cytotoxicity against the host MT-4 cells. (C) 2002 Elsevier Science Ltd. All rights reserved.
