  Diarylspiro[2.4]heptenes as Orally Active, Highly Selective Cyclooxygenase-2 Inhibitors:  Synthesis and Structure−Activity Relationships

  摘要：

  A novel series of 5,6-diarylspiro[2.4]hept-5-enes was shown to provide highly potent and selective cyclooxygenase-2 (COX-2) inhibitors. A study of structure-activity relationships in this series suggests that 3,4-disubstituted phenyl analogs are generally more selective than 4-substituted phenyl analogs and that replacement of the methyl sulfone group on the B-phenyl ring with a sulfonamide moiety results in compounds with superior in vivo pharmacological properties, although with lower COX-2 selectivity, Several compounds have been shown to possess promising pharmacological properties in adjuvant-induced arthritis and edema analgesia models. The absence of gastrointestinal (GI) toxicity at 200 mpk of several selected compounds in rats and mice corresponds well with the weak potency for inhibition of COX-1 observed in the enzyme assay. Methyl sulfone 55 and sulfonamide 24 were shown to have superior in vivo pharmacological profiles, low GI toxicity, and good oral bioavailability and duration of action.

  A palladium catalyst under visible light irradiation activates cyclobutanone oxime ester through single electron transfer to induce radical ring opening to generate hybrid cyanoalkyl Pd(I) radical species. Hybrid cyanoalkyl Pd(I) radical species can undergo either β-H elimination to deliver (E)-4-arylbut-3-enenitrile or undergo radical addition with silyl enol ether and enamide to generate δ-cyano

  A catalytic defluorinative ring‐opening indolylation of siloxydifluorocyclopropanes was reported. It was found that AgBF4‐catalyzed reaction of siloxydifluorocyclopropanes with indoles could be controlled to deliver α‐fluoro‐β‐indolyl‐propanones within 1.5 hours at room temperature. Cyclization of these α‐fluoroketone derivatives were then carried out in the presence of trifluoroacetic anhydride in

• LADA strategy for the synthesis of unnatural amino acids and direct modifications of peptides
  作者：Jun-Liang Zhou、Yun-Qi Liu、Zhan-Kui Sun

  Unnatural amino acids (UAAs) are important building blocks in organic synthesis and drug discovery. They are also frequently integrated into peptides or proteins for biological studies. However, the direct and simplified synthesis of UAAs remains a great challenge. At the same time, vast known peptide modifications are based on carbon-heteroatom bonds. There are no general methods for peptide modifications

  非天然氨基酸 (UAA) 是有机合成和药物发现的重要组成部分。它们还经常被整合到用于生物学研究的肽或蛋白质中。然而，UAA 的直接和简化合成仍然是一个巨大的挑战。同时，大量已知的肽修饰是基于碳-杂原子键。没有通过构建 C-C 键对肽进行修饰的通用方法。为了应对这一挑战，我们在此提出了 LADA 策略，该策略由两个步骤组成：半胱氨酸残基的选择性标记和激活，脱硫生成以碳为中心的自由基和自由基a加入烯烃以建立C-C键。这种一锅法方案具有明显的优点，例如良好的官能团耐受性、生物相容性反应条件和保留的立体化学。该策略已成功用于非天然氨基酸的合成和肽的直接修饰。
