  • Copper(I)-Catalyzed Addition of Grignard Reagents to in Situ-Derived <i>N</i>-Sulfonyl Azoalkenes: An Umpolung Alkylation Procedure Applicable to the Formation of Up to Three Contiguous Quaternary Centers
    作者:John M. Hatcher、Don M. Coltart
    DOI:10.1021/ja100932q
    日期:2010.4.7
    that has considerable potential with regard to catalysis and the direct incorporation of functionality not amenable to the use of enolate chemistry. Herein, we describe the first Cu(I)-catalyzed addition of Grignard reagents to in situ-derived N-sulfonyl azoalkenes. This method is remarkable in its ability to deliver highly sterically hindered compounds that would be difficult or impossible to synthesize
    N-磺酰腙的 α-烷基化通过原位衍生的偶氮烯烃提供了酮 α-烷基化的 umpolung 方法,该方法在催化和直接结合不适合使用烯醇化学的官能团方面具有相当大的潜力。在此,我们描述了首次在 Cu(I) 催化下将格氏试剂添加到原位衍生的 N-磺酰基偶氮烯烃中。这种方法能够提供通过传统烯醇化学难以或不可能合成的高度位阻化合物,包括具有多达三个连续四元中心的化合物。

    Treatment of α-(dimethylthiocarbamoylthio) ketones with bakersyeast afforded the corresponding chiral alcohols in high yields with high enantiomeric excess (in most cases, more than 96% ee). α-(Dimethylthiocarbamoylthio) aldehydes were reduced to give chiral α-(dimethylthiocarbamoylthio) alcohols in 69–92% yields with 32–63% ee, which were converted to chiral 1,2-epithio derivatives.

  • Deriving the Meaning of Unknown Words From Multiple Contexts
    作者:Maartje van Daalen-Kapteijns、Marianne Elshout-Mohr、Kees de Glopper
    DOI:10.1111/0023-8333.00150
    日期:2001.3
    Students from 11 to 12 years old were invited to derive the meaning of five unknown words, each embedded in three contexts. We focused on the students' proficiency in three activities: decontextualization of the target word meanings from the contexts (decontextualization), testing initial ideas about the word meanings with subsequent contexts (cumulative testing), and formulating dictionary-like definitions
    邀请 11 至 12 岁的学生推导五个未知单词的含义,每个单词都嵌入三个上下文中。我们专注于学生在三项活动中的熟练程度:从上下文中去除目标词的含义(去上下文化),用后续上下文测试对单词含义的初步想法(累积测试),以及制定类似字典的定义(定义)。我们比较了八名语言能力高的学生和八名低语言能力的学生。学生们被单独引导,通过导出目​​标词的含义的过程,同时大声思考。研究表明,即使是语言能力低的年轻学生也能够进行意义推导活动,而这些活动通常归因于语言能力高的成熟学生。
  • Activation of Transforming Growth Factor β in Chondrocytes Undergoing Endochondral Ossification
    作者:Marina D'Angelo、David P. Sarment、Paul C. Billings、Maurizio Pacifici
    DOI:10.1359/jbmr.2001.16.12.2339

    Transforming growth factor β (TGF‐β) has well‐documented roles in chondrocyte maturation and endochondral ossification, but the mechanisms of TGF‐β activation during these processes remain unclear. In this study, we analyzed TGF‐β activation in chick embryo resting, proliferating, and hypertrophic chondrocytes in culture. We found that both levels and activation of TGF‐β increased substantially with maturation. The majority of TGF‐β produced by resting cells over culture time remained latent, but a larger portion produced by proliferating and hypertrophic cells was activated with increasing maturation. Zymography of gelatin gels revealed that matrix metalloprotease 2 (MMP‐2) and MMP‐9 were expressed by each population and that MMP‐13 characterized hypertrophic chondrocytes and to a lesser extent proliferating chondrocytes in late cultures. Treatment with pharmacologic agents revealed that both MMPs and serine proteases are involved in activation. However, because inhibition of MMPs almost completely prevented TGF‐β activation, MMPs appear crucial for activation. During culture, inclusion of the tetracycline‐derived, collagenase/gelatinase inhibitor chemically modified nonantimicrobial tetracycline (CMT‐8) at concentrations specific for MMP‐13 inhibition resulted in complete inhibition of TGF‐β activation by proliferating and hypertrophic chondrocytes. These results show that TGF‐β production, release, and activation are regulated developmentally in chondrocytes. Our findings point to a strict mode of regulation of this potent factor to elicit diverse and highly specific effects during chondrocyte maturation and ossification.
    转化生长因子 β(TGF-β)在软骨细胞成熟和软骨内骨化过程中的作用已被充分证明,但这些过程中 TGF-β 的激活机制仍不清楚。在这项研究中,我们分析了小鸡胚胎静止、增殖和肥大软骨细胞在培养过程中的 TGF-β 激活情况。我们发现,随着细胞的成熟,TGF-β的水平和活化程度都大幅增加。静止细胞在培养过程中产生的大部分 TGF-β 仍处于潜伏状态,但增殖和肥大细胞产生的大部分 TGF-β 随着成熟度的增加而被激活。明胶凝胶的酶谱分析显示,基质金属蛋白酶2(MMP-2)和MMP-9在每个细胞群中都有表达,MMP-13是肥大软骨细胞的特征,增殖软骨细胞在晚期培养中表达较少。用药剂处理后发现,MMPs 和丝氨酸蛋白酶都参与了活化。然而,由于抑制 MMPs 几乎完全阻止了 TGF-β 的活化,因此 MMPs 似乎对活化至关重要。在培养过程中,以抑制 MMP-13 的特异浓度加入四环素衍生的胶原酶/明胶酶抑制剂化学修饰非抗菌四环素(CMT-8),可完全抑制增殖和肥大软骨细胞的 TGF-β 激活。这些结果表明,软骨细胞中 TGF-β 的产生、释放和活化是受发育调控的。我们的研究结果表明,在软骨细胞成熟和骨化过程中,这种强效因子具有严格的调节模式,可产生多种高度特异性的效应。
