  Synthesis and biological evaluation of 5-substituted and 4,5-disubstituted-2-arylamino oxazole TRPV1 antagonists

  摘要：

  The synthesis and structure-activity relationships of a series of 5-monosubstituted and 4,5-disubstituted 2-arylaminooxazoles as novel antagonists of the transient receptor potential vanilloid 1 (TRPV1) receptor are described. The 7-hydroxy group of the tetrahydronaphthyl moiety on the 2-amino substituent of the oxazole ring was important for obtaining excellent in vitro potency at the human TRPV1 receptor, while a variety of alkyl and phenyl substituents at the 4- and 5-positions of the oxazole ring were well tolerated and yielded potent TRPV1 antagonists. Despite excellent in vitro potency, the 5-monosubstituted compounds suffered from poor pharmacokinetics. It was found that 4,5-disubstitution on the oxazole ring was critical to the improvement of the overall pharmacokinetic profile of these analogues, which led to the discovery of compound (R)-27, a novel TRPV1 antagonist with good oral activity in preclinical animal models of pain.

  vinyl arenes with trimethylsilylazide and molecular oxygen as stoichiometric oxidant was achieved. In contrast to photocatalysts based on iridium, ruthenium, or organic dyes, [Cu(dap)2]Cl or [Cu(dap)Cl2] were found to be unique for this transformation, which is attributed to their ability to interact with the substrates through ligand exchange and rebound mechanisms. CuII is proposed as the catalytically

  用三甲基甲硅烷基叠氮化物和分子氧作为化学计量氧化剂实现了乙烯基芳烃的可见光加速氧化叠氮化。与基于铱，钌或有机染料的光催化剂相反，发现[Cu（dap）2 ] Cl或[Cu（dap）Cl 2 ]对于这种转化是独特的，这归因于它们与金属，金属或金属的相互作用。底物通过配体交换和反弹机制。有人建议将铜II作为催化活性物质，将其与叠氮化物配位后将进行光加速均质分解，从而形成铜I和叠氮化物自由基。这种激活原则（CU II -X→铜我+ X 。）开启了铜基光催化的新途径。

  一种基于光催化制备ɑ‑叠氮酮化合物的方法，基于下述反应式：其中R1为任意取代的芳基、杂芳基、1‑12碳烷基；R2为任意取代的芳基、杂芳基、或1‑12碳烷基、氢原子。通式I所示的物设置为烯烃,通式II所示的物设置为叠氮基三甲基硅烷(TMSN3)，通式III所示的物设置为ɑ‑叠氮酮化合物，采用在可见光催化下合成ɑ‑叠氮酮化合物。由于设计了光催化剂，采用在可见光催化下，以空气为氧化剂合成ɑ‑叠氮酮化合物，不再使用当量的无机氧化剂、金属试剂、以及预先制备复杂的原料，因此降低了反应条件，提高了反应的安全性。

  In the present study, a series of dibenzoazepine triazole derivatives (24-39) were synthesized and evaluated for their in vitro bioactivities including antiglycation, antibacterial, DPPH radical scavenging, urease inhibition, antileishmanial and immunomodulatory activities. The compounds were found to be moderately active only against leishmania. Within this series, compound 26 was found to be the most active antileishaminals with IC50 value 37.4 ± 0.4 µM. Structure-activity relationships for this novel class are discussed.
