Design and synthesis of 3-(2-pyridyl)pyrazolo[1,5-a]pyrimidines as potent CRF1 receptor antagonists
摘要:
A series of 3-(2-pyridyl)pyrazolo[1,5-a]pyrimidines was designed and synthesized as antagonists for the corticotrophinreleasing factor-1 (CRF1) receptor. Several compounds such as 20c (K-i = 10nM) exhibited good binding affinities at the CRF1 receptor. In addition, 20c had adequate solubility in water. (C) 2004 Elsevier Ltd. All rights reserved.
The present invention provides a compound having a glucosylceramide lowering action (e.g., promoting glucosylceramide metabolism, inhibition of glucosylceramide synthesis, promoting glucosylceramide catabolism, etc.), which is expected to be useful as an agent for the prophylaxis or treatment of lysosome diseases (e.g., Gaucher's disease), neurodegenerative diseases (e.g., Parkinson's disease, Lewy body dementia, multiple-system atrophy) and the like.
The present invention relates to a compound represented by the formula (I)
wherein each symbol is as described in the specification, or a salt thereof.

report relatively simple and cost-effective orthogonal tandem catalysis, namely Ag2O in conjunction with Cs2CO3 serves to promote a multicomponent tandem reaction forming two new C–C and one new C–N bonds. 4H-Quinolizin-4-ones, key skeletal components in a variety of biologically active molecules, were obtained with yields up to 99%. The present approach features a broad substrate scope and mild reaction
本文使用二氧化碳作为C1的前体,我们报告了相对简单且经济高效的正交串联催化,即Ag 2 O与Cs 2 CO 3结合可促进多组分串联反应,形成两个新的C–C和一个新的C– N个债券。获得了4 H -Quinolizin-4-ones,这是多种生物活性分子中的关键骨架成分,产率高达99%。本方法具有广泛的底物范围和温和的反应条件,并受益于使用具有成本效益的反应和催化剂。
Palladium-catalyzed direct deprotonative arylation of 2-pyridylacetonitriles: Facile synthesis of alpha-aryl-2-pyridylacetonitrile
α-Aryl-2-pyridylacetonitrile, an important chemical intermediate, was synthesized via direct deprotonative arylation of 2-pyridylacetonitrile with aryl bromides. Pd(OAc)2/NixantPhos-based catalysis system promoted this arylation reaction to furnish diverse α-aryl-2-pyridylacetonitrile derivatives in wide range function group tolerance and high yield (80%-97%).
