A new furopyrimidine compound, their pharmaceutically acceptable salt, and a tyrosine kinase activity inhibitor. The furopyrimidine compound is a compound defined by chemical formula 1, 2, 3 or 4, on their precursor, and can exist as a form of free base or in an acid-addition salt. Since the furopyrimidine compound has an effect of inhibiting activity of DDR2 tyrosine kinase, it can be used in treating illnesses caused by the DDR2 tyrosine kinase activity such as hepatocirrhosis, rheumatoid arthritis or cancer.

A novel copper-catalyzed [3+2] cycloaddition reaction with concomitant in situ generation of benzoylacrylonitriles and nitrile imines from phenacylmalononitriles and hydrazonoyl chlorides, respectively, is reported. The reaction was performed using copper(I) chloride as catalyst and N-methylimidazole as a clean complexing agent/weak base to afford the functionalized 4-benzoyl-5-cyanopyrazoles in moderate

The synthesis and pharmacological analyses of a number of furo[2,3-b]quinolin-4-amine, and pyrrolo[2,3-b]quinolin-4-amine derivatives are reported. Thus, we synthesized diversely substituted tacrine analogues 1–11 and 12–16 by Friedländer-type reaction of readily available o-amino(furano/pyrrolo)nitriles with suitable and selected cycloalkanones. The biological evaluation of furanotacrines 1–11 and
报道了许多呋喃并[2,3 - b ]喹啉-4-胺和吡咯并[2,3 - b ]喹啉-4-胺衍生物的合成和药理学分析。因此,我们合成了不同地取代的他克林的类似物1 - 11和12 - 16由容易获得的德兰德型反应ø -氨基(呋喃/吡咯)与合适的和选定的环烷酮腈。的生物学评价furanotacrines 1 - 11和pyrrolotacrine 13表明,这些都是很好的,在微摩尔范围内,和丁酰胆碱酯酶的高度选择性抑制剂。在呋喃诺那林中组中,最有趣的抑制剂是2-(对甲苯基)-5,6,7,8-四氢呋喃[2,3- b ]喹啉-4-胺(3)[IC 50(eqBuChE)= 2.9±0.4μM ; IC 50(hBuChE)= 119±15μM]。相反,吡咯烷酮 12和14被证明对两种胆碱酯酶具有中等等价性,分别是1,2-二苯基-5,6,7,8-四氢-1 H-吡咯并[2,3 - b ]喹啉-4-胺(12)。对两种酶的抑制作用最强[IC
