Quinoline, isoquinoline, quinoxaline, and quinazoline derivatives were synthesized using microwave-assisted synthesis and their CB1/CB2 receptor activities were determined using the [35S]GTPγS binding assay. Most of the prepared quinoline, isoquinoline, and quinoxalinyl phenyl amines showed low-potency partial CB2 receptor agonists activity. The most potent CB2 ligand was the 4-morpholinylmethanone
使用微波辅助合成法合成喹啉,异喹啉,喹喔啉和喹唑啉衍生物,并使用[ 35 S]GTPγS结合测定法测定其CB1 / CB2受体活性。大部分制备的喹啉,异喹啉和喹喔啉基苯胺均显示出低效的部分CB2受体激动剂活性。最有效的CB2配体是4-吗啉基甲酮衍生物(化合物40e)(-log EC 50 = 7.8;E max = 75%)。异喹啉-1-基(3-三氟甲基-苯基)胺(化合物26c)是一种高效的CB2激动剂(-log EC 50 = 5.8; E max = 128%)。在这些研究中,没有发现明显的CB1受体激活或失活,除了40e表现出弱的CB1激动剂活性(CB1-log EC 50 = 5.0)。这些配体用作开发选择性CB2受体激动剂的新型模板。

heated with an excess of aromatic amine are unexpectedly complex. For example, when 2-chloroquinoxaline is heated with excess aniline a mixture of the expected anilino derivative (1), 6H-indolo[2,3-b]quinoxaline (7), 2,3-dianilinoquinoxaline (11), and 2-p-ainino-phenyl-3-anilinoquinoxaline (16) is obtained.
当2-氯喹喔啉与过量的芳族胺一起加热时发生的反应出乎意料的复杂。例如,当将2-氯喹喔啉与过量的苯胺一起加热时,预期的苯胺基衍生物(1),6H-吲哚并[2,3- b ]喹喔啉(7),2,3-二苯并喹喔啉(11)和2-的混合物得到对氨基苯苯基-3-苯胺基喹喔啉(16)。

aromatic and aliphatic azides with boronic acids under iron-catalyzed conditions. The amination follows an unprecedented metalloradical activation mechanism that is different from traditional metal-catalyzed C–N cross-coupling reactions. The scope of the reaction has been demonstrated by the employment of a large number of tetrazoles, azides, and boronic acids. Moreover, several late-stage aminations

Novel substituted 2-anilino- and 2-cycloalkylaminoquinoxalines have been found to be useful and selective inhibitors of PDGF-R autophosphorylation. Replacement of an anilino-substituent with substituted cyclohexylamino- or norbornylamino substituents led to significant improvements in the pharmacokinetic profile of these analogues.
