    Pharmaceutical potential of phorbol esters fromJatropha curcasoil
    摘要:
    Phorbol esters (PEs) are diterpenes present in Jatropha curcas L. seeds and have a myriad of biological activities. Since PEs are toxic, they are considered to be futile in Jatropha-based biodiesel production chain. In the present study, the extracted PEs from Jatropha oil were used as a starting material to synthesise pharmacologically important compound, prostratin. The prostratin synthesised from Jatropha showed identical mass with that of the reference standard prostratin, as determined by Nano-LC-ESI-MS/MS. Considering the rapid growth in Jatropha biodiesel industry, potential exists to harness large amount of PEs which can be further utilised to synthesise prostratin as a value added product.

    ABC-ring 6 by detaching the three-carbon units and the oxygen-appended groups. Intermediate 6 with six stereocenters was assembled from four achiral fragments in 12 steps by integrating three powerful transformations, as follows: (i) asymmetric Diels–Alder reaction to induce formation of the C-ring; (ii) π-allyl Stille coupling reaction to set the trisubstituted E-olefin of the B-ring; and (iii) Eu(fod)3-promoted

    This invention concerns a process to convert a hydroxyl group (bold in R 3 C—OH) in a tigliane-type compound to a hydrogen (bold in R 3 C—H) to obtain deoxytigliane-type compounds or structural or functional analogs thereof. The process has wide application particularly to produce specific biologically active compounds in quantity for use as pharmaceuticals. In particular the process can be used to convert phorbol to a 12-deoxytigliane (prostrating which is a therapeutic lead for the treatment of AIDS. New compositions of matter are also disclosed.

  • Highly potent, synthetically accessible prostratin analogs induce latent HIV expression in vitro and ex vivo

    Highly active antiretroviral therapy (HAART) decreases plasma viremia below the limits of detection in the majority of HIV-infected individuals, thus serving to slow disease progression. However, HAART targets only actively replicating virus and is unable to eliminate latently infected, resting CD4 + T cells. Such infected cells are potentially capable of reinitiating virus replication upon cessation of HAART, thus leading to viral rebound. Agents that would eliminate these reservoirs, when used in combination with HAART, could thus provide a strategy for the eradication of HIV. Prostratin is a preclinical candidate that induces HIV expression from latently infected CD4 + T cells, potentially leading to their elimination through a virus-induced cytopathic effect or host anti-HIV immunity. Here, we report the synthesis of a series of designed prostratin analogs and report in vitro and ex vivo studies of their activity relevant to induction of HIV expression. Members of this series are up to 100-fold more potent than the preclinical lead (prostratin) in binding to cell-free PKC, and in inducing HIV expression in a latently infected cell line and prostratin-like modulation of cell surface receptor expression in primary cells from HIV-negative donors. Significantly, selected members were also tested for HIV induction in resting CD4 + T cells isolated from infected individuals receiving HAART and were found to exhibit potent induction activity. These more potent agents and by extension related tunable analogs now accessible through the studies described herein should facilitate research and preclinical advancement of this strategy for HIV/AIDS eradication.

    高效抗逆转录病毒疗法(HAART)可将大多数HIV感染者的血浆病毒载量降至检测限度以下,从而减缓疾病进展。然而,HAART仅针对活跃复制的病毒,无法消除潜伏感染的静止CD4+ T细胞。这些感染细胞有可能在停止HAART后重新启动病毒复制,导致病毒反弹。与HAART结合使用的能够消除这些储存库的药物,可能提供一种根除HIV的策略。Prostratin是一种临床前候选药物,可以从潜伏感染的CD4+ T细胞中诱导HIV表达,可能通过病毒诱导的细胞病变效应或宿主抗HIV免疫机制来消除它们。在这里,我们报告了一系列设计的Prostratin类似物的合成,并报告了与诱导HIV表达相关的它们的体外和体内研究结果。该系列中的成员在与无细胞PKC的结合和在潜伏感染的细胞系中诱导HIV表达方面比临床前领先药物(Prostratin)高达100倍,并在来自HIV阴性供体的原代细胞中诱导HIV表达和类Prostratin的细胞表面受体表达调节方面表现出相似的效果。值得注意的是,选择的成员还在接受HAART的感染者中分离的静止CD4+ T细胞中进行了HIV诱导测试,并发现它们具有强效的诱导活性。这些更强效的药物以及通过本文所述的研究现在可以获得的相关可调控类似物,应有助于促进这种用于HIV/AIDS根除的策略的研究和临床前进展。

    The structure and stereochemistry of phorbol, a novel tetracyclic diterpene containing a reactive hydroxycyclopropyl carbinol system, is discussed. It undergoes protonation at the homoallylic 12-hydroxy-group and gives crotophorbolone (an isopropenyl cyclohexanone) and crotophorbolone K (a dimethyl cyclobutanone). With boron trifluoride–acetic acid, phorbol triacetate gives an acetoxy-isopropyl cyclohexanone
