  Synthesis and structure-activity relationships of a novel series of non-peptide angiotensin II receptor binding inhibitors specific for the AT2 subtype

  摘要：

  Structure-activity relationships are reported for a novel class of 4,5,6,7-tetrahydro-1H-imidazo[4,5-c]pyridine-6-carboxylic acid derivatives that displace I-125-labeled angiotensin II from a specific subset of angiotensin II (Ang II) binding sites in rat adrenal preparations. This binding site is not the Ang II receptor mediating vascular contraction or aldosterone release, but, rather, is one whose function has not yet been fully elucidated. It has been identified in a number of tissues and has a similar affinity for Ang II and its peptide analogues as does the vascular receptor. The non-peptide compounds reported here are uniquely specific in displacing Ang II at this binding site and are inactive in antagonizing Ang II at the vascular receptor or in pharmacological assays measuring vascular effects. PD 123,319 (79), one of the most potent compounds, has an IC50 of 34 nM. Certain of these compounds may have utility in the definition and study of Ang II receptor subtypes.

• Palladium‐Catalyzed Reductive Carbonylation of (Hetero) Aryl Halides and Triflates Using Cobalt Carbonyl as CO Source

  日期：2021.1.15

  A generalized protocol for the reductive carbonylation of (hetero) aryl halides and triflates under CO gas‐free conditions using Pd/Co2(CO)8 and triethylsilane has been developed. The mild reaction conditions, enhanced safety, and wide substrate scope highlight its importance in routine organic synthesis.

  已经开发了一种通用协议，用于在无CO气体条件下使用Pd / Co 2（CO）8和三乙基硅烷对（杂）芳基卤化物和三氟甲磺酸进行还原羰基化。温和的反应条件，增强的安全性和广泛的底物范围突出了其在常规有机合成中的重要性。
