  Statin-derived 1,3-oxazinan-2-ones as submicromolar inhibitors of LFA-1/ICAM-1 interaction: stabilization of the metabolically labile vanillyl side chain

  摘要：

  Modification of the vanillyl substituent on a potent, semisynthetic lymphocyte function-associated antigen (LFA)1/intercellular adhesion molecule (ICAM)-1 binding inhibitor of the statin family resulted in metabolically more stable analogues that displayed submicromolar inhibitory activity in vitro and considerable anti-inflammatory activity in vivo. The benzodioxole derivative 2b emerged with the best overall profile. (C) 2004 Elsevier Ltd. All rights reserved.

  土曲霉突变体对环状九环的转化阻止了lovA和lovC基因的洛伐他汀生物合成。

  摘要：

  检查了具有lovC或lovA基因被破坏的两个曲霉曲霉突变体的能力，这些突变体可将九肽转化为洛伐他汀1（一种降胆固醇药物）。lovC破坏剂能够有效地将二氢莫纳可林L 5或莫纳可林J 9转化为1，还可以将去甲基莫纳可林J 15转化为紧致蛋白3。相反，lovA突变体具有意想不到的活性β-氧化系统，仅产生少量的1在加入直接前体9后，大部分添加的非核苷酸都降解为庚肽22。类似地，lovA突变体不会积聚聚酮化合物合酶产物5，并通过两个β-氧化和β-环化反应迅速降解了作为前体添加的任何5。在C-6处羟基化得到20。

  Two new dehydromonacolins (1 and 3), together with nine known monacolins (4-12), were isolated from red yeast rice. Compounds 4-6 were isolated from a natural resource for the first time. Their structures were elucidated by means of NMR and mass spectroscopic analyses. The structure of dehydromonacolin N (1) was further confirmed by its semisynthesis from monacolin K (lovastatin) (11). Dehydromonacolin J (2), an intermediate in the semisynthesis of 1, was obtained as a new dehydromonacolin. The structure of dehydromonacolin L (3) was also confirmed by an elimination reaction of monacolin L (12). Compound 1, possessing a C2 side chain, is unprecedented in the natural monacolin family and exhibited moderate cytotoxic activity against Hep G2, Caco-2, and MCF-7 cancer cell lines. Dehydromonacolin K (8) demonstrated the most potent cytotoxicity to all three of these cell lines. The structure activity relationship of natural and synthesized monacolins was discussed. This is the first report on the cytotoxic effects of dehydromonacolins.
