Abstract
Iron-catalyzed oxidative synthesis of N-aryl-substituted tetrahydroisoquinolines (THIQs) toward tetrahydroisoquinoline-based derivatives is reported. A wide range of α-amino nitriles and tetrahydroisoquinolinones are synthesized in moderate to good yields. This approach involves a new organic nitrile source, a cheap iron catalyst under an oxygen atmosphere, and temperature-controlled divergent synthesis and features complete selectivity and operational simplicity.

Abstract
In this study, an efficient method for the synthesis of sulfur-substituted 4-enyl-2-pyrrolidones was successfully developed through AIBN-promoted highly selective 5-exo-dig radical cascade cyclization of 1,6-enynes with sulfur sources with the aid of theoretical and computational chemistry. This protocol enables the first practical and green synthesis of an array of 4-enyl-2-pyrrolidones in moderate-to-good yields with broad substrate scopes and high regioselectivities (>20:1). Moreover, excellent stereoselectivities have also been achieved (up to >20:1, Z/E). Most interestingly, when the sulfur source is electron-rich thiophenol, reverse stereoselectivities were discovered. In addition, the control experiments indicate that the cascade cyclization is realized by radical reactions, and the detailed reaction mechanism and regioselectivities have also been explained by theoretical studies.

A highly efficient domino aza-MIRC (Michael Induced Ring Closure) reaction between barbiturate-derived alkenes and N-alkoxy α-haloamides has been achieved in moderate to excellent yields. This reaction proceeds smoothly under mild conditions via a domino aza-Michael addition/intramolecular SN2 sequence, providing a practical tool in the synthesis of bioactive molecules spirobarbiturate-3-pyrrolidinones.

Abstract
The γ-lactam moiety is present in a large number of natural and non-natural biologically active compounds. The range of biological activities covered by these compounds is very broad. Functionalized γ-lactams are thus of high interest and have great potential in medicinal chemistry. This review provides a description of the title compounds by focusing on their synthesis, natural sources and biological activities.

Abstract
A metal-free strategy for the formation of lactams via selective oxidation of cyclic secondary and tertiary amines is described. Molecular iodine facilitates both chemoselective and regioselective oxidation of C-H bonds directly adjacent to a cyclic amine. The mild conditions, functional group tolerance, and substrate scope are demonstrated using a suite of diverse small molecule cyclic amines, including clinically approved drug scaffolds.

Abstract
The interaction of the agonist JN403 with the human (h) alpha7 nicotinic acetylcholine receptor (AChR) was compared to that for the competitive antagonist methyllycaconitine (MLA). The receptor selectivity of JN403 was studied on the halpha7, halpha3beta4, and halpha4beta2 AChRs. The results established that the cationic center and the hydrophobic group found in JN430 and MLA are important for the interaction with the AChRs. MLA preincubation inhibits JN403-induced Ca(2+) influx in GH3-halpha7 cells with a potency 160-fold higher than that when MLA is co-injected with JN403. The most probable explanation, based on our dynamics results, is that MLA (more specifically the 3-methyl-2,5-dioxopyrrole ring and the B-D rings) stabilizes the resting conformational state. The order of receptor specificity for JN403 is as follows: halpha7 > halpha3beta4 ( approximately 40-fold) > halpha4beta2 ( approximately 500-fold). This specificity is based on a larger number of hydrogen bonds between the carbamate group (another pharmacophore) of JN403 and the halpha7 sites, the electrostatic repulsion between the positively charged residues around the halpha3beta4 sites and the cationic center of JN403, fewer hydrogen bonds for the interaction of JN403 with the halpha3beta4 AChR, and an unfavorable van der Waals interaction between JN403 and the alpha4-beta2 interface. The higher receptor specificity for JN403 could be important for the treatment of alpha7-related disorders, including dementias, pain-related ailments, depression, anxiety, and wound healing.

Abstract
Accumulating evidence suggests that α7 nicotinic receptors (α7 nAChRs), a subtype of nAChRs, play a role in the pathophysiology of neuropsychiatric diseases, including schizophrenia and Alzheimer's disease (AD). A number of psychopharmacological and genetic studies shown that α7 nAChRs play an important role in the deficits of P50 auditory evoked potential in patients with schizophrenia, and that (α nAChR agonists would be potential therapeutic drugs for cognitive impairments associated with P50 deficits in schizophrenia. Furthermore, some studies have demonstrated that α7 nAChRs might play a key role in the amyloid-β (Aβ)-mediated pathology of AD, and that α7 nAChR agonists would be potential therapeutic drugs for Aβ deposition in the brains of patients with AD. Interestingly, the altered expression of α7 nAChRs in the postmortem brain tissues from patients with schizophrenia and AD has been reported. Based on all these findings, selective α7 nAChR agonists can be considered potential therapeutic drugs for cognitive impairments in both schizophrenia and AD. In this article, we review the recent research into the role of α7 nAChRs in the pathophysiology of these diseases and into the potential use of novel α7 nAChR agonists as therapeutic drugs.

Abstract
A novel alpha 7 nAChR agonist, 4-(5-methyloxazolo[4,5-b]pyridin-2-yl)-1,4-diazabicyclo[3.2.2]nonane (24, CP-810,123), has been identified as a potential treatment for cognitive deficits associated with psychiatric or neurological conditions including schizophrenia and Alzheimer's disease. Compound 24 is a potent and selective compound with excellent pharmaceutical properties. In rodent, the compound displays high oral bioavailability and excellent brain penetration affording high levels of receptor occupancy and in vivo efficacy in auditory sensory gating and novel object recognition. The structural diversity of this compound and its preclinical in vitro and in vivo package support the hypothesis that alpha 7 nAChR agonists may have potential as a pharmacotherapy for the treatment of cognitive deficits in schizophrenia.
