Structure-activity studies on a novel series of cholinergic channel activators based on a heteroaryl ether framework
摘要:
Analogs of compound 1 with a variety of azacycles and heteroaryl groups were synthesized. These analogs exhibited K-i values ranging from 0.15 to 1 10,000 nM when tested in vitro for cholinergic channel receptor binding activity (displacement of [H-3](-) cytisine from whole rat brain synaptic membranes).

The present invention provides compounds of Formula I and the pharmaceutically acceptable salts thereof, which are inhibitors of the ROMK (Kir1.1) channel. The compounds may be used as diuretic and/or natriuretic agents and for the therapy and prophylaxis of medical conditions including cardiovascular diseases such as hypertension, heart failure and chronic kidney disease and conditions associated with excessive salt and water retention.
Seventy novel benzoylphenylurea compounds were synthesized and their antitumor activities were examined in vivo against P388 leukemia. N-(2-Nitrobenzoyl)-N'-[4-(2-pyrimidinyloxy)phenyl]ureas showed the highest antitumor activities when dosed intraperitoneally or orally. Their structure-activity relationships were examined with particular focus on the position and the variety of subsitituent on each aryl ring.

distinctive copper-catalyzed radical annulation to valuable 2-(trifluoromethyl)pyrazolo[1,5-a]pyridines and their benzo analogues has been described for the first time. Notably, the newly developed complementary process allows the synthesis of 4- or 6-substituted target molecular entities as a single product, which was previously challenging to access by existing methods. The utility of this process is further
首次描述了一种机制独特的铜催化自由基环化对有价值的 2-(三氟甲基)吡唑并[1,5- a ] 吡啶及其苯并类似物的反应。值得注意的是,新开发的补充工艺允许将 4 或 6 取代的目标分子实体作为单一产品合成,这在以前很难通过现有方法获得。该过程的实用性通过四种不同环系统的简易构建、克级合成和生物活性分子的后期功能化得到进一步证明。
Graphitic Carbon Nitride as a Photocatalyst for Decarboxylative C(sp2)−C(sp3) Couplings via Nickel Catalysis
Decarboxylative C(sp2)−C(sp3) bondformation using a metallaphotoredox approach is a key method for rapidly building molecular complexity. In this work, we demonstrate that graphitic carbonnitride, a heterogeneous semiconductor, can act as a suitable photocatalyst to induce decarboxylative bondformation. A broad scope of coupling partners is presented, in addition to photocatalystrecycling, analysis,
