Design, synthesis of symmetrical bivalent mimetics of annonaceous acetogenins and their cytotoxicities
摘要:
A new series of linear dimeric compounds mimicking naturally occurring annonaceous acetogenins have been synthesized by bivalent analogue design, and their cytotoxicities have been evaluated against the growth of cancer cells by MTT method. Most of these compounds show selective action favored to human cancer cell lines over normal cell lines, and compound 9 with bis-terminal benzoquinone functionality exhibits an IC(50) = 0.40 mu M against MCF7 cell lines. This work mentions that appropriate conformational constraints might be a useful optimizing tool for this unique class of anticancer compounds. (C) 2011 Elsevier Ltd. All rights reserved.
Annonaceousacetogenins are a large family of naturally occurring polyketides exhibiting remarkable anticancer activities. The first generation of annonaceousacetogenin mimetic (1, AA005) exhibits comparable activity as that of natural products and presents much higher selectivity between cancer and normal cells. In this work, we report the design, synthesis, and evaluation of a new series of compound

A synthesis of trilobin, a new stereochemical varient of the adjacent bis-tetrahydrofuran subgroup of the Annonaceousacetogenins, is described. The synthesis involves three stereochemically defining carbon-carbon bond-forming steps. The first of these introduces the C23-C24 stereocenters and the left side chain by means of an S(E)2' addition of the nonracemic 11-carbon gamma-oxygenated allylic indium
A convergent synthesis of pyrrolidine analogues of solamin, which possessed a pyrrolidine in place of the tetrahydrofuran ring, was presented in a facile route from 2,5-trans-bis(methoxycarbonyl)pyrrolidine. The stereochemistry of pyrrolidine core unit was determined by 1H NMR spectroscopic analysis.

Annonaceous acetogenins are a series of potent naturally occurring anticancer agents, which act as inhibitors of complex I in mitochondria. AA005, a mimicry of acetogenins, has been found as active as those natural products and to present high selectivities between cancer and normal cells. In order to investigate the further cell-based mechanism induced by AA005, a d(4)-labeled derivative of AA005 (AA005-d(4)) was designed to detect the drug permeation ability into the membranes. In this letter, the synthesis is reported of this deuterium-labeled compound, wherein a ethylene-d(4) glycol unit is incorporated efficiently into the molecule skeleton by simple etherifications.
