  The Synthesis of Radermachol

  摘要：

  Five different approaches to the preparation of 6,7-benzo-3,4-(1,4-dimethoxy-2,3-naphtho)-1,5-dioxosuberane (3), an intermediate needed for the synthesis of radermachol (1), the red pigment from the roots of Radermachera xylocarpa, are described. The synthesis of radermachol (1) has been accomplished from 1,4-nephthoquinone in 14 steps.

  The first asymmetric hydrogenation of 3‐ylidenephthalides has been developed using the IrI complex of a spiro[4,4]‐1,6‐nonadiene‐based phosphine‐oxazoline ligand (SpinPHOX) as the catalyst, affording a wide variety of chiral 3‐substituted phthalides in excellent enantiomeric excesses (up to 98 % ee). The utility of the protocol has been demonstrated in the asymmetric synthesis of chiral drugs NBP and

• Anti-HIV activity of stilbene-related heterocyclic compounds

  Viral transcription has not been routinely targeted in the development of new antiviral drugs. This crucial step of the viral cycle depends on the concerted action of cellular and viral proteins such as NF-kappa B and Tat. In the present study, stilbene-related heterocyclic compounds including benzalphthalide, phthalazinone, imidazoindole and pyrimidoisoindole derivatives are tested for their anti-HIV activity. Original assays based on recombinant viruses were used to evaluate HIV replication inhibition and stably transfected cell lines were used to evaluate inhibition of Tat and NF-kappa B proteins. Some of the stilbene-related heterocyclic compounds analysed displayed anti-HIV activity through interference with NF-kappa B and Tat function. Moreover, compounds inhibiting both targets displayed a stronger activity on viral replication. (c) 2006 Elsevier Ltd. All rights reserved.

  Several series of dihydrostilbenamide, imidazo[2,1-a]isoindole, pyrimido[2,1-a]isoindole and phthalazinone derivatives were obtained and their vasorelaxant activity was measured on isolated rat aorta rings pre-contracted with phenylephrine (10(-5) M). Some phthalazinones attained, practically, the total relaxation of the organ at micromolar concentrations. For the most potent compound 9h (EC50 = 0.43 mu M) the affinities for alpha(1A), alpha(1B) and alpha(1D) adrenergic sub-receptors were determined. (C) 2006 Elsevier Ltd. All rights reserved.
