- Discovery of a new class of multi-target heterocycle piperidine derivatives as potential antipsychotics with pro-cognitive effect
-
A series of benzoisoxazoleylpiperidine derivatives were synthesized by using the multi-target strategies and their potent affinities for dopamine (DA), serotonin (5-HT) and human histamine H3 receptors have been evaluated. Of these compounds, t

- ZnAl2O4–Bi2O3 composite nano-powder as an efficient catalyst for the multi-component, one-pot, aqueous media preparation of novel 4H-chromene-3-carbonitriles
-
Abstract: A composite structure of ZnAl2O4–Bi2O3 nanopowder was prepared from the reaction of a watery solution of Zn(NO3)2, Al(NO3)3, and Bi(NO3)3 with a dilute solution of amino ethanol in water via a simple precipitation-complexation method. The as-prepared composite was used for the one-pot synthesis of 2-amino-4-aryl-7-(pyrrolidin-1-yl)-4H-chromene-3-carbonitrile, 2-amino-4-aryl-7-(piperidin-1-yl)-4H-chromene-3-carbonitrile, 2-amino-4-aryl-7-(1H-pyrrol-1-yl)-4H-chromene-3-carbonitrile, 2-amino-4-aryl-6-(2-(piperidin-1-yl)ethyl)-4H-chromene-3-carbonitrile and 2-amino-4-aryl-6-(1H-pyrrol-1-yl)-4H-chromene-3-carbonitrile derivatives. This procedure is very simple and affords excellent yields. Graphical Abstract: [Figure not available: see fulltext.]

- 2-Phenoxy-indan-1-one derivatives as acetylcholinesterase inhibitors: A study on the importance of modifications at the side chain on the activity
-
As a part of our project aimed at developing new agents of potential application in AD, a new series of 2-phenoxy-indan-1-one derivatives which possess alkylamine side chain were designed, synthesized, and evaluated for their inhibitory activity against AChE and BuChE. Most of the compounds were found to inhibit AChE in the nanomolar range. The optimum inhibitor 3g exhibited 34-fold increase in AChE inhibition than donepezil and displayed neuroprotective effect against H2O2-induced cell death.

- Identification of a potent, selective, and orally active leukotriene A 4 hydrolase inhibitor with anti-inflammatory activity
-
LTA4H is a ubiquitously distributed 69 kDa zinc-containing cytosolic enzyme with both hydrolase and aminopeptidase activity. As a hydrolase, LTA4H stereospecifically catalyzes the transformation of the unstable epoxide LTA4 to the diol LTB4, a potent chemoattractant and activator of neutrophils and a chemoattractant of eosinophils, macrophages, mast cells, and T cells. Inhibiting the formation of LTB4 is expected to be beneficial in the treatment of inflammatory diseases such as inflammatory bowel disease (IBD), asthma, and atherosclerosis. We developed a pharmacophore model using a known inhibitor manually docked into the active site of LTA4H to identify a subset of compounds for screening. From this work we identified a series of benzoxazole, benzthiazole, and benzimidazole inhibitors. SAR studies resulted in the identification of several potent inhibitors with an appropriate cross-reactivity profile and excellent PK/PD properties. Our efforts focused on further profiling JNJ 27265732, which showed encouraging efficacy in a disease model relevant to IBD.
