  • General syntheses of 1-alkyltoxoflavin and 8-alkylfervenulin derivatives of biological significance by the regioselective alkylation of reumycin derivatives and the rates of transalkylation from 1-alkyltoxoflavins into nucleophiles
    作者:Tomohisa Nagamatsu、Hirofumi Yamasaki
    DOI:10.1039/b007302o
    日期:——
    Regioselective alkylations of reumycin derivatives under alkaline conditions with a dialkyl sulfate or alkyl halide in 1,4-dioxane or DMF to provide 1-alkyltoxoflavin or 8-alkylfervenulin derivatives of biological significance, are described. Namely, the primary and secondary alkylations of reumycin derivatives with appropriate dialkyl sulfates or alkyl bromides under alkaline conditions in 1,4-dioxane gave predominantly 1-alkyltoxoflavin derivatives, while the same alkylations in DMF instead of 1,4-dioxane gave predominantly 8-alkylfervenulin derivatives. In the case of tertiary alkylation, the reumycin derivative with 2-bromo-2-methylpropane in both solvents under the same conditions yielded only the 1-alkyltoxoflavin derivative. Moreover, the rates of transalkylation from 1-alkyltoxoflavin derivatives into nucleophiles, e.g. DMF and n-butylamine, are also described. That is, the toxoflavin derivatives possessing a primary alkyl group at the 1-position were easily dealkylated from the 1-position by heating with DMF, whereupon reumycin (i.e., 1-dealkyltoxoflavin, 8-dealkylfervenulin) derivatives were formed. In other words, transalkylation from the toxoflavin derivatives into DMF took place. However, the transalkylation of 1-alkyltoxoflavin derivatives possessing a secondary or tertiary alkyl group at the 1-position was not observed under such conditions. On the other hand, when heating 1-alkyltoxoflavin derivatives with n-butylamine in 1,4-dioxane, the transalkylations were more easily observed even in the case of 1-alkyltoxoflavin derivatives substituted by a tertiary alkyl group.
    在碱性条件下,使用二烷基硫酸酯或烷基卤化物在1,4-二恶烷或DMF中对reumycin衍生物进行区域选择性烷基化,生成具有生物学意义的1-烷基toxoflavin或8-烷基fervenulin衍生物,本文对此进行了描述。即,在碱性条件下,使用适当的二烷基硫酸酯或烷基溴化物在1,4-二恶烷中对reumycin衍生物进行伯和仲烷基化,主要生成1-烷基toxoflavin衍生物,而在DMF中替代1,4-二恶烷进行同样的烷基化,则主要生成8-烷基fervenulin衍生物。在叔烷基化的情况下,在相同条件下,使用2-溴-2-甲基丙烷在两种溶剂中的reumycin衍生物仅生成1-烷基toxoflavin衍生物。此外,还描述了从1-烷基toxoflavin衍生物向亲核试剂(例如DMF和正丁胺)的转移烷基化速率。也就是说,在1-位具有伯烷基的toxoflavin衍生物通过与DMF加热容易从1-位去烷基化,随后形成reumycin(即1-去烷基toxoflavin,8-去烷基fervenulin)衍生物。换言之,从toxoflavin衍生物向DMF发生了转移烷基化。然而,在1-位具有仲或叔烷基的1-烷基toxoflavin衍生物的转移烷基化在这些条件下未被观察到。另一方面,当在1,4-二恶烷中加热1-烷基toxoflavin衍生物与正丁胺时,即使在1-位上被叔烷基取代的1-烷基toxoflavin衍生物的情况下,转移烷基化也更容易被观察到。

    Protein disulfide isomerase (PDI) is overexpressed in glioblastoma, the most aggressive form of brain cancer, and folds nascent proteins responsible for the progression and spread of the disease. Herein we describe a novel nanomolar PDI inhibitor, pyrimidotriazinedione 35G8, that is toxic in a panel of human glioblastoma cell lines. We performed a medium‐throughput 20 000‐compound screen of a diverse

  • Toxoflavins and Deazaflavins as the First Reported Selective Small Molecule Inhibitors of Tyrosyl-DNA Phosphodiesterase II

    The recently discovered enzyme tyrosyl-DNA phosphodiesterase 2 (TDP2) has been implicated in the topoisomerase-mediated repair of DNA damage. In the clinical setting, it has been hypothesized that TDP2 may mediate drug resistance to topoisomerase II (topo II) inhibition by etoposide. Therefore, selective pharmacological inhibition of TDP2 is proposed as a novel approach to overcome intrinsic or acquired resistance to topo II-targeted drug therapy. Following a high-throughput screening (HTS) campaign, toxoflavins and deazaflavins were identified as the first reported sub-micromolar and selective inhibitors of this enzyme. Toxoflavin derivatives appeared to exhibit a clear structure-activity relationship (SAP.) for TDP2 enzymatic inhibition. However, we observed a key redox liability of this series, and this, alongside early in vitro drug metabolism and pharmacokinetics (DMPK) issues, precluded further exploration. The deazaflavins were developed from a singleton HTS hit. This series showed distinct SAR and did not display redox activity; however low cell permeability proved to be a challenge.
