  Synthesis and topoisomerase I inhibitory activity of a novel diazaindeno[2,1-b]phenanthrene analogue of Lamellarin D

  摘要：

  A novel 5-oxa-6a,8-diazaindeno[2,1-b]phenanthren-7-one scaffold was designed and synthesized as an active analogue of the cytotoxic marine alkaloid Lamellarin D. The design was based on molecular modeling of the site of interaction of Lamellarin D with DNA-topoisomerase I cleavable complex, whereas the synthesis capitalized on a simple Friedel-Crafts cyclization of indole to a beta-carbolinone nucleus. The product exhibited topoisomerase I poisoning activity and submicromolar cytotoxicity on human non-small cell lung cancer H460 cell line. (C) 2011 Elsevier Ltd. All rights reserved.

  Synthesis of N -benzyl-des- D -ring lamellarin K via an acyl-Claisen/Paal-Knorr approach

  摘要：

  Lamellarin K is a complex pyrrole natural product and member of the lamellarin family - a group of natural products known for their potent biological activities, such as, antiproliferative activity and inhibition of P-gp mediated drug efflux pumps. We herein describe the synthesis of the N-benzyl-des-D ring analogue of lamellarin K using a route that centres on an acyl-Claisen reaction to eventually prepare a highly-functionalised 1-aryl-4-methyl-1,4-diketone. Paal-Knorr pyrrole formation using this diketone undergoes auto-oxidation to give a fully-substituted 5-formyl pyrrole which was converted into the natural lactone B ring. Antiproliferative testing of the N-benzyl-des-D ring analogue gave an IC50 of 2.63 mu M against the MDA-MB-231 breast cancer cell line. (C) 2017 Elsevier Ltd. All rights reserved.

  The acyl-Claisen rearrangement of substituted phenylacetyl chlorides and cinnamyl morpholines gives 2,3-syn-diarylpent-4-enamides. Electron-rich cinnamyl morpholines containing alkoxy substituents only reacted with phenylacetyl chlorides; replacement of the phenylacetyl chlorides with alkyl acid chlorides in these reactions gave no rearranged products. Use of the morpholine amides generated in the
