  Structural Properties of Dibenzosuberanylpiperazine Derivatives for Efficient Reversal of Chloroquine Resistance in Plasmodium chabaudi

  摘要：

  For the purpose of developing chemosensitizers to reverse chloroquine (CQ) resistance in Plasmodium chabaudi in vivo, dibenzosuberanylpiperazine (1-(10,11-dihydro-5H-dibenzo[a,d]-cyclohepten-5-yl)piperazine) (DSP) and its piperazin-1-yl derivatives were synthesized systematically. DSP hydrochloride (3) was obtained from the reaction of dibenzosuberanyl chloride with piperazine in the presence of 1,8-diazabicyclo[5,4,0]-7-undecene (DBU). To understand the relationship between the substituent patterns of DSP derivatives and their biological activities, 13 hydroxyalkyl or hydroxyalkenyl derivatives were synthesized by an attack of the piperazine secondary amine of 3 on commercially available epoxides in the presence of triethylamine or DBU, and three alkyl or alkynyl derivatives were synthesized by the reactions of 3 with the corresponding organic chlorides in the presence of DBU. In both reactions, the yield was a maximum of 90%. The biological activities of the synthesized compounds were evaluated on the basis of two values: antimalarial activity and reversal activity. The values of antimalarial activities by single administration of 17 test compounds were not effective, being in the range 67-152% on day 4 after infection of Plasmodium chabaudi to mice except for the administration of 3-(dibenzosuberanylpiperazin-1-yl)-1-butene (29, 22%). On the other hand, administration of the seven test compounds (50 mg/kg dose) combined with CQ (3-4 mg/kg) gave high reversal activities, namely, low values (0% on day 4). The effective test compounds were those obtained by introducing the following substituents: 2-hydroxybutyl (24), 2-hydroxyhexen-5-yl (27), 2-hydroxybuten-3-yl (28a), 2-substituted 1-hydroxybuten-3-yl (28b), 4-acetoxybutyn-2-yl (30), 4-hydroxybutyn-2-yl (31), and 3-substituted buten-1-yl (29), which correspond to the nonbulky groups of hydroxyalkyl (C4), hydroxyalkenyl (C4-C6), hydroxyalkynyl (C4), or alkenyl (C4). These results may lead to the development of an approach to developing clinically applicable chemosensitizers for drug-resistant malaria.

  of enyne self-immolative polymers (SIPs) capable of metathesis cascade-triggered depolymerization is reported. Studies on model compounds established 1,6-enyne structures for efficient metathesis cascade reactions. SIPs incorporating the optimized 1,6-enyne motif were prepared via both polycondensation and iterative exponential growth approaches. These SIPs demonstrated excellent stability in strong

  报道了一类能够进行复分解级联触发解聚的新型烯炔自燃聚合物 (SIPs)。对模型化合物的研究建立了用于高效复分解级联反应的 1,6-烯炔结构。通过缩聚和迭代指数增长方法制备了包含优化的 1,6-烯炔基序的 SIP。这些 SIP 在强酸、强碱、亲核试剂或高温下表现出优异的稳定性，并且一旦被复分解催化剂触发，就可以进行有效和完全的解聚。进一步的研究表明，在烯炔 SIPs 的链端引入末端烯烃提高了解聚效率，并确立了它们作为刺激响应材料的潜力。

  A range of metathesis substrates was assembled from triplets of unsaturated building blocks. The approach involved the iterative attachment of a propagating and a terminating building block to a fluorous-tagged initiating building block. Metathesis cascade chemistry was used to "reprogram" the molecular scaffolds. Remarkably, in one case, a cyclopropanation reaction competed with the expected metathesis

  Rule of thumb: The high yielding title reaction is described with a focus on understanding the factors that govern the regioselectivity of the process (see scheme). Electronic, steric, and functional group properties all influence the selectivity, an understanding of which allows the selective formation of trisubstituted vinylsilanes, which are synthetically useful compounds for accessing stereodefined

  A two-step reaction sequence starting with the indium-mediated allenylation of aldehydes with 4-bromo-2-butyn-1-ols and subsequent ozonolysis of the resulting allenylic product was developed to generate a variety of dihydroxyacetone derivatives. The regioselectivity of the indium-promoted C–C bond-forming reaction can be manipulated through hydroxy protecting groups on 4-bromo-2-butyn-1-ol, yielding
