The invention relates to heteroaryl compounds, pharmaceutically acceptable salts thereof, and pharmaceutical preparations thereof. Also described herein are compositions and the use of such compounds in methods of treating diseases and conditions mediated by deficient CFTR activity, in particular cystic fibrosis.
CO2 and water are the only byproducts of this process, and the reaction conditions can scale up to gram quantities. The transformation involves an unprecedented tBuOK-catalyzed domino process, and features Michael addition/6π-electrocyclic ring opening/[1,5]-H shift/carba-6π-electrocyclic ring closure/decarboxylative aromatization reactions.
new methodology for the synthesis of fluorinated and non‐fluorinated 1H‐pyrazolo[3,4‐b]pyridin‐3‐ones was developed. The reactions proceed by cyclization of electron‐rich 3‐amino‐1H‐pyrazol‐5(4H)‐ones with 1,3‐diketones and the products were obtained in good to excellent yields and with excellent regioselectivity. The products, which can be regarded as deazapurine analogues, were tested for the alkaline
为氟化和非氟化的1的合成的新方法ħ -吡唑并[3,4- b ]吡啶-3-酮被开发。反应是通过将富含电子的3-氨基-1 H-吡唑-5(4 H)-1与1,3-二酮环化而进行的,所获得的产物具有良好的产率和极好的区域选择性。该产品可被视为脱氮嘌呤类似物,已测试了碱性磷酸酶(h- TNAP和h- IAP)和核苷酸焦磷酸酶/磷酸二酯酶(h- NPP1和h‐NPP3)抑制曲线。大多数衍生物对组织非特异性和肠道碱性磷酸酶和核苷酸焦磷酸酶(NPP1和NPP3)酶表现出选择性和有效的抑制作用。通过分子对接分析研究了最有效抑制剂的可能结合方式。
Liver X Receptor (LXR) partial agonists: Biaryl pyrazoles and imidazoles displaying a preference for LXRβ
A series of biaryl pyrazole and imidazole LiverXReceptor (LXR) partial agonists has been synthesized displaying LXRβ selectivity. The LXRβ selective partial agonist 18 was identified with potent induction of ATP binding transporters ABCA1 and ABCG1 in human whole blood (EC50 = 1.2 μM, 55% efficacy). In mice 18 displayed peripheral induction of ABCA1 at 3 and 10 mpk doses with no significant elevation
A visible‐light photoredox‐catalyzed reaction of tetrahydroisoquinolines with β‐fluorinated gem‐diols results in the formation of C1‐monofluoromethylated tetrahydroisoquinolines via C(sp3)Hbondactivation. This protocol provides a new method to introduce a CF group with stable, easily‐prepared monofluorinated gem‐diol as CF source. A mechanistic investigation is presented based on control experiments
