  Preparation and evaluation of deconstruction analogues of 7-deoxykalafungin as AKT kinase inhibitors

  摘要：

  The pyranonaphthoquinone (PNQ) lactone natural products, including 7-deoxykalafungin, have been reported to be potent and selective covalent inhibitors of AKT kinase. In this work we seek to identify structural features of the natural product scaffold that are essential for potency and selectivity. Using a deconstruction approach, we designed and prepared simplified analogues of 7-deoxykalafungin. Testing of the compounds for their ability to inhibit AKT and the closely related kinase PKA revealed that the 3,6-dihydro-2H-pyran ring of the PNQ lactones is required for potent and selective inhibition of AKT. We have also unexpectedly identified a new submicromolar inhibitor of PKA. (C) 2013 Elsevier Ltd. All rights reserved.

• Enantioselective Synthesis of (−)-5-Deoxyjuglomycin A⁺
  作者：H. Rama Mohan、A. S. Rao

  DOI：10.1080/00397919308012591

  日期：1993.9

  Starting from methyl 1,4-dimethoxynaphthalene-2-acetate (4), (-)-5-deoxy juglomycin A (3) has been prepared in 6 steps; the overall yield is 79%. The key step in the synthesis is the asymmetric hydroxylation of the beta , gamma-unsaturated ester (8), leading to the hydroxylactone (9) having 96% ee.

  The naturally occurring pyranonaphthoquinone (PNQ) antibiotic lactoquinomycin and related aglycones were found to be selective inhibitors of the serine-threonine kinase AKT. A set of synthetic PNQs were prepared and a minimum active feature set and preliminary SAR were determined, PNQ lactones inhibit the proliferation of human tumor cell lines containing constitutively activated AKT and show expected effects on cellular biomarkers. Biochemical data are presented supporting a proposed bioreductive alkylation mechanism of action.
• Direct Oxa-Pictet−Spengler Cyclization to the Natural (3a,5)-<i>trans</i>-Stereochemistry in the Syntheses of (+)-7-Deoxyfrenolicin B and (+)-7-Deoxykalafungin

  DOI：10.1021/jo801945n

  日期：2009.1.2

  The pyranonaphthoquinones (+)-7-deoxyfrenolicin B and (+)-7-deoxykalafungin were synthesized in four steps using an oxa-Pictet-Spengler cyclization that directly provided the natural (3a,5)-trans-substituted dihydronaphthopyrans with high diastereoselectivity. This outcome is in contrast to the unnatural (3a,5)-cis-substituted dihydronaphthopyrans reported under similar conditions for the syntheses of (+)frenolicin B and (+)-kalafungin. Computational modeling is presented that provides insight into this unusual stereoselectivity.
