  摘要：

  据报道，在中性条件下，由偶氮二羧酸二异丙酯介导的2-氨基-3-氰基4 H-色酮选择性脱氢为相应的2-亚氨基色酮。脱氢反应与酚羟基相容并以高收率产生亚氨基色烯。该方法提供了香豆素和N-甲苯磺酰基2-氨基-3-氰基-4-芳基4 H-色烯的容易获得。

  Synthesis, biological assessment, and molecular modeling of racemic 7-aryl-9,10,11,12-tetrahydro-7H-benzo[7,8]chromeno[2,3-b]quinolin-8-amines as potential drugs for the treatment of Alzheimer's disease

  摘要：

  The synthesis, pharmacological analysis and molecular modeling of the readily available racemic tacrine analogs 21-30, bearing the 7-aryl-9,10,11,12-tetrahydro-7H-benzo[7,8]chromeno[2,3-b[quinolin-8-amine heterocyclic ring system (II), prepared by Friedlander reaction of 2-amino-4-aryl-4H-benzo[h] chromene-3-carbonitriles (11-20) with cyclohexanone, are described in this paper. Molecules 21-30 are potent and selective inhibitors of hAChE, in the low micromolar range, one of the most potent inhibitors, 4-(8-amino-9,10,11,12-tetrahydro-7H-benzo[7,8]chromeno[2,3-blquinolin-7-y1)-2-methoxyphenol (25), showing a IC50 (hAChE) = 0.33 +/- 0.04 mu M. Kinetic studies of compound 25 proved that this compound is a mixed type inhibitor for EeAChE (K-i=81 nM). Accordingly, molecular modeling of inhibitor 25 showed that both enantiomers have two major predicted binding modes at the active and at the peripheral anionic sites of AChE. Inhibitor 25 has an excellent antioxidant profile as determined in the ORAC experiment (1.47 +/- 0.10 Trolox equiv). Inhibitors 26-28 and 30 are permeable to BBB as determined in the PAMPA assay. Compared to tacrine, selected compounds 26-28 and 30 showed less hepatic toxicity in HepG2 cells. Moreover, cell viability-related studies in cortical neurons in primary cultures show that compounds 26-28 and 30 (0.1-50 mu M) have significant neuroprotective effects against mitochondrial chain blockers-induced cell death, and, unlike tacrine, are not neurotoxic at concentrations lower than 50 mu M. It is worth highlighting that compound 27 has the best neuroprotective properties out of all assayed compounds and shows no neurotoxicity. To sum up, these tacrine analogs can be considered as attractive multipotent therapeutic molecules on pharmacological receptors playing key roles in the progress of Alzheimer's disease.
