    Synthesis of 7-Substituted Farnesyl Diphosphate Analogues
    摘要:
    [GRAPHICS]Six farnesyl diphosphate analogues modified in the central isoprene unit have been prepared via our stereoselective vinyl triflate-mediated route to isoprenoids. The 7-allyl compound 6 is a modest inhibitor of mammalian protein-farnesyl transferase, but surprisingly the other five analogues are effective alternative substrates for this enzyme.

  • Effet de solvant sur support solide:régiosélectivité de l'alkylation des énolates de l'acétylacétate d'éthyle par le sulfate d'éthyle en présence de “hmpt solide”

    compared: for the K enolate the reaction is faster and the degree of O-alkylation higher with solid HMPA; practically no difference is seen for Na enolate, while the reverse is observed with the Li enolate. The cooperative effect of the polymer should thus only work for a sufficiently large cation, as the Li enolate is fixed on the solid HMPA in a larger amount than the K enolate. The study of this
    室温下,在一摩尔当量的固体HMPA存在下,乙酸乙酯中的Li,Na,K烯酸酯与硫酸二乙酯在THF中的反应得到60-70%的O-烷基化。在没有HMPA的情况下,在相同条件下,烯醇化锂不会发生反应,烯醇化钠只会产生C-烷基化,而烯醇化钾会导致90%的C-烷基化,在后两种情况下反应相当慢。比较了一摩尔当量的固体和液体HMPA的影响:对于烯醇化物,固体HMPA的反应更快,O-烷基化程度更高;实际上,对于烯醇钠而言,没有发现差异,而对于烯醇锂,则观察到相反的情况。因此,聚合物的协同作用应仅对足够大的阳离子起作用,因为烯醇酸锂以比烯醇酸钾更大的量固定在固体HMPA上。

In a similar manner, 3-allylgeranylgeraniol acts as a highly specific inhibitor of protein geranylgeranylation, while 3-vinylgeranylgeraniol restores protein geranylgeranylation in cells. This study indicates that certain prenyl alcohol

    unified, stereospecific synthetic route to the three geometric isomers of (E,E)-farnesyl diphosphate (E,E-FPP) (1, 2, and 3) has been developed. The key feature of this synthesis is the ability to control the stereochemistry of triflation of the beta-ketoester 10 to give either 11 or 14. Preliminary evaluation of these compounds with protein-farnesyl transferase indicates that 1 and 2 are surprisingly

  • Inhibition of Glucose- and Calcium-Induced Insulin Secretion from βTC3 Cells by Novel Inhibitors of Protein Isoprenylation

    The majority of low molecular weight G proteins undergoes a series of post-translational modification steps, e.g., isoprenylation, at their C-terminal cysteine, which seem to be critical for the transport of the modified proteins to the membrane sites for interaction with their respective effector proteins. Using lovastatin, an inhibitor of mevalonic acid, and hence, isoprenoid biosynthesis, we demonstrated previously that protein isoprenylation is critical for physiological insulin secretion from normal rat islets. Herein, we used more selective synthetic inhibitors of protein prenylation to examine their effects on glucose- and calcium-mediated insulin secretion from βTC3 cells. Both 3-allyl- and vinylfarnesols, which inhibit and/or modulate protein farnesyl transferases, significantly (80–95%) inhibited glucose- and KCl-stimulated insulin secretion from these cells. In a similar manner, the allyl and vinyl forms of geranylgeraniol, reagents targeted toward protein geranylation, attenuated insulin secretion elicited by glucose and KCl. Furthermore, manumycin A, a natural inhibitor of protein farnesylation, and geranylgeranyl transferase inhibitor-2147 (GGTI-2147), a peptidomimetic inhibitor of protein geranylgeranylation, also inhibited glucose- and KCl-induced insulin secretion to comparable degrees. Treatment of βTC3 cells with either 3-vinylfarnesol or 3-vinyl geranylgeraniol resulted in accumulation of unprenylated proteins in the cytosolic fraction. These data further support our original formulation that inhibition of isoprenylation of small molecular weight G proteins might impede their interaction with their putative effectors, which may be required for physiological insulin secretion.
    大多数低分子量的 G 蛋白在其 C 端半胱氨酸处经历了一系列翻译后修饰步骤,如异戊烯化,这似乎是将修饰后的蛋白运输到膜位点与其各自的效应蛋白相互作用的关键。洛伐他汀是甲羟戊酸的抑制剂,因此也是异戊烯生物合成的抑制剂,我们之前利用洛伐他汀证明了蛋白质异戊烯化对正常大鼠胰岛的生理性胰岛素分泌至关重要。在这里,我们使用了更具选择性的蛋白质前炔化合成抑制剂来研究它们对葡萄糖和钙介导的βTC3细胞胰岛素分泌的影响。抑制和/或调节蛋白法尼酰转移酶的 3-烯丙基和乙烯基法尼醇都能显著(80-95%)抑制这些细胞在葡萄糖和 KCl 刺激下分泌胰岛素。与此类似,针对蛋白质香叶基化的试剂香叶基烯丙基和乙烯基形式的香叶基炔醇也能减弱葡萄糖和氯化钾引起的胰岛素分泌。此外,法尼基化蛋白的天然抑制剂 manumycin A 和拟肽抑制剂 geranylgeranyl 转移酶抑制剂-2147(GGTI-2147)也能在相当程度上抑制葡萄糖和氯化钾诱导的胰岛素分泌。用 3-vinylfarnesol 或 3-vinyl geranylgeraniol 处理 βTC3 细胞会导致未肾上腺素化的蛋白质在细胞膜部分积累。这些数据进一步支持了我们最初的观点,即抑制小分子量 G 蛋白的异戊烯化可能会阻碍它们与其可能的效应物之间的相互作用,而这可能是生理性胰岛素分泌所必需的。
