  Total synthesis and evaluation of lamellarin α 20-Sulfate analogues

  摘要：

  In order to explore the influence of sulfate groups on the bioactivity profiles of marine alkaloids of the lamellarin class, three such alkaloids, lamellarin alpha, lamellarin alpha 13,20-disulfate and lamellarin H, were synthesized and their activities against HIV-1 integrase and cancer cell lines were compared with those of lamellarin alpha 20-sulfate, which is a selective inhibitor of HIV-1 integrase. Lamellarin alpha does not inhibit HIV-1 integrase but shows moderate cytotoxicity with good cell line selectivity. Lamellarin alpha 13,20-disulfate is a moderate inhibitor of both HIV-1 integrase and cancer cell lines. Lamellarin H is a more potent inhibitor of HIV-1 integrase but lacked the specificity required to be medicinally useful. (C) 2002 Elsevier Science Ltd. All rights reserved.

• Synthesis of Lamellarins via Regioselective Assembly of 1,2-Diarylated [1]Benzopyrano[3,4-b]pyrrol-4(3H)-one Core

  A modular synthesis of lamellarins has been developed. The key reactions in this synthesis are the assembly of 1,2-diarylated [1]benzopyrano[3,4-b]pyrrol-4(3H)-ones from a preexisting [1]benzopyrano[3,4-b]pyrrol4(3H)-one core and the appropriate arylboronic acids. The obtained 1,2-diarylated [1]benzopyrano[3,4-b]pyrrol-4(3H)-ones could be easily converted into the corresponding lamellarin derivatives

  已经开发了层状蛋白的模块化合成。该合成中的关键反应是由预先存在的[1]苯并吡喃[3,4-b]吡咯4( 3H)-一个核心和适当的芳基硼酸。得到的1,2-二芳基[1]苯并吡喃[3,4-b]pyrrol-4(3H)-ones可以通过吡咯氮和C2芳环之间的分子内环化很容易地转化为相应的层状结构衍生物。引言 层层素是一种多环吡咯生物碱，具有独特的 14-苯基-6H-[1]苯并吡喃[4́,3́:4,5]吡咯并[2,1-a]异喹啉-6-环系统。在极少数情况下（层状蛋白 O、P、Q 和 R），这些化合物具有简单的非稠合 3,4-diarylpyrrole-2-carboxylate 结构。自从第一次从海洋前支软体动物 Lamellaria sp. 中分离出层状蛋白 A-D。1985 年，从被囊类动物、海绵类和前枝类动物中分离出 50 多种层状蛋白。这些层状蛋白表现出广泛的有用生物活性：针对几种癌细胞系的有效抗增殖活性、多药耐药性
• Synthesis, structure–activity relationships, and mechanism of action of anti-HIV-1 lamellarin α 20-sulfate analogues

  Lamellarin a and six different types of lamellarin alpha 20-sulfate analogues were synthesized and their structure-activity relationships were investigated using a single round HIV-1 vector infection assay. All lamellarin sulfates having pentacyclic lamellarin core exhibited anti-HIV-1 activity at a 10 mu M concentration range regardless of the number and position of the sulfate group. On the other hand, non-sulfated lamellarin alpha and ring-opened lamellarin sulfate analogues did not affect HIV-1 vector infection in similar concentrations. The lamellarin sulfates utilized in this study did not exhibit unfavorable cytotoxic effect under the concentrations tested (IC50 > 100 mu M). Confocal laser scanning microscopic analysis indicated that hydrophilic lamellarin sulfates were hardly incorporated in the cell. HIV-1 Env-mediated cell-cell fusion was suppressed by lamellarin sulfates. These results suggested that lamellarin sulfates have a novel anti-HIV-1 activity besides the previously reported integrase activity inhibition, possibly at a viral entry step of HIV-1 replication.

• Total Synthesis of Natural and Unnatural Lamellarins with Saturated and Unsaturated D-Rings
  作者：Poonsakdi Ploypradith、Thaninee Petchmanee、Poolsak Sahakitpichan、Nichole D. Litvinas、Somsak Ruchirawat

  日期：2006.12.1

  Twenty-eight natural and unnatural lamellarins with either a saturated or an unsaturated D-ring were synthesized according to our developed synthetic route. The key step involved the Michael addition/ring closure (Mi-RC) of the benzyldihydroisoquinoline and alpha-nitrocinnamate derivatives, which provided the 2-carboethoxypyrrole intermediates in moderate to good yields (up to 78% yield). Subsequent hydrogenolysis/lactonization furnished lamellarins with a saturated D-ring in excellent yields (up to 93% yield). DDQ oxidation of the saturated lamellarin acetates led directly to the corresponding unsaturated analogues in 54-95% yield. In addition, only two steps in our developed strategy require column chromatography.
• Divergent Synthesis of Lamellarin α 13-Sulfate, 20-Sulfate, and 13,20-Disulfate
  作者：Masatomo Iwao、Tsutomu Fukuda、Sho Saeki、Takeshi Ohta

  日期：——

  A divergent synthesis of three sulfate derivatives of lamellarin alpha, namely, lamellarin alpha 13-sulfate (2), 20-sulfate (1), and 13,20-disulfate (4) has been achieved via a common intermediate (6) in which 13-OH and 20-OH of the lamellarin core are differentially protected by MOM and benzyl groups, respectively. Compound (6) in turn was prepared using sequential Suzuki-Miyaura coupling of 3,4-dihydroxypyrrole bistriflate (7) as a key reaction.
