    三异丙醇硼B(O i Pr)3化学选择性还原醛和酮的新方法:与三乙醇硼B(OEt)3的比较
    摘要:
    描述了多种脂族和烯丙基α,β-不饱和醛和酮的化学选择性Meerwein-Ponndorf-Verley还原过程。该化学选择性还原由三异丙氧基硼B(O i Pr)3催化。还研究了醛和酮还原为相应醇的动力学,并测量了每种羰基化合物的速率常数。比较了在B(O i Pr)3存在下与在B(OEt)3存在下的每种羰基化合物的速率常数和还原产率。通过GC-MS分析作为还原产物的醇。发现使用B(OEt)的速率常数和酒精产率更高3(与B(O i Pr)3相比)。所提出的机理涉及六元过渡态,其中醇和羰基均与烷氧基硼催化剂的相同硼中心配位。 描述了在三异丙醇硼B(O i Pr)3存在下化学选择性Meerwein-Ponndorf-Verley(MPV)还原各种脂族和烯丙基α,β-不饱和醛和酮的方法。将结果与在B(OEt)3存在下获得的结果进行比较。

  • Synthesis of Thiophene and NO-Curcuminoids for Antiinflammatory and Anti-Cancer Activities
    作者:Mahera Ahmed、M. Khan、Kim Rainsford
    DOI:10.3390/molecules18021483
    日期:——
    In search of better NSAIDs four novel nitric oxide donating derivatives of curcumin (compounds 9a–d), and four thiophene curcuminoids (compounds 10a–c, 11) have been synthesised. The cytotoxic effects of these compounds along with the lead compound curcumin (7) and their effect on the production of the reactive oxygen species nitric oxide and pro-inflammatory cytokines IL-1β, TNF-α and chemokine CXCL-8 were evaluated using human monocytic THP-1 and colon adenocarcinoma CACO-2 cell lines. All of the nitric oxide donating curcuminoids 9a–d and the thiophene curcuminoids 10a–c and 11 were non-cytotoxic to THP-1 cells over a concentration range of 10-100 μM and compared with curcumin compounds 10b and 10c, were more toxic. In CACO-2 cells, 10b and 11 appeared to be non-toxic at 10 to 50 μM, whereas 10a and 10c were non-cytotoxic at 10 μM only. These results clearly indicate that the introduction of a nitroxybutyl moiety to curcumin and replacement of phenyl rings with thiophene units reduces the cytotoxic effect of the parent curcumin, whereas a methyl substituted thiophene increases the cytotoxic effects. In THP-1 cells, drugs 10a and 11 significantly decreased IL-1-β production at their non-cytotoxic concentrations, whereas, they did not decrease TNF-α production in CACO-2 cells. Compound 11 showed a significant decrease in CXCL-8 production.
    为了寻找更好的非甾体抗炎药(NSAIDs),合成了四种新型的捐赠一氧化氮姜黄素生物(化合物9a-d)和四种噻吩姜黄素(化合物10a-c, 11)。使用人单核细胞THP-1和结肠腺癌CACO-2细胞系评估了这些化合物与领先化合物姜黄素(7)的细胞毒性效应,以及它们对活性氧物种一氧化氮和促炎细胞因子IL-1β、TNF-α和趋化因子CXCL-8产生的影响。所有的捐赠一氧化氮姜黄素生物9a-d和噻吩姜黄素10a-c及11在10-100 μM浓度范围内对THP-1细胞均无细胞毒性,而与姜黄素化合物10b和10c相比,则具有更高的毒性。在CACO-2细胞中,10b和11在10至50 μM时似乎无毒,而10a和10c仅在10 μM时无细胞毒性。这些结果清晰表明,将一氧化氮基团引入姜黄素并用噻吩单元替换苯环可以降低母体姜黄素的细胞毒性,而甲基取代的噻吩则提高了细胞毒性。在THP-1细胞中,药物10a和11在其无细胞毒性浓度下显著降低了IL-1β的产生,而在CACO-2细胞中,则未降低TNF-α的产生。化合物11显示出CXCL-8产生的显著减少。
  • Kinetics and rate constants for reactions associated with organoborane autoxidations

    The thermal decomposition of the peroxides BunOOBBun2, (BunOO)2BBun, and (BusOO)2BBus occurs predominantly by a non-radical process with a low enthalpy and large negative entropy of activation. A minor homolytic decomposition was detected in vinyl acetate. The primary initiation, R3B + O2 [graphic omitted] radicals, was also investigated and ki was found to be 1.7 ± 0.2 × 10–5 for tri-s-butylborane;

    The syntheses of triisopropyl borate and other boric acid esters under conditions of mechanochemical activation with the use of zeolite catalysts were found to be highly efficient. The proposed method exhibits the following advantages over known methods: short synthesis times, low energy consumption, higher yields of target products, and the absence of byproducts. The mechanism of the catalytic esterification of boric acid under conditions of mechanochemical activation is discussed.
