Abstract
Drug-induced enhanced dopamine (DA) signaling in the brain is a canonical mechanism that initiates addiction processes. However, indirect evidence suggests that cocaine also triggers non-canonical, DA-independent, mechanisms that contribute to behavioral responses to cocaine, including psychomotor sensitization and cocaine self-administration. Identifying these mechanisms and determining how they are initiated is fundamental to further our understanding of addiction processes. Using physiologically relevant in vitro tractable models, we found that cocaine-induced hypoactivity of nucleus accumbens shell (NAcSh) medium spiny neurons (MSNs), one hallmark of cocaine addiction, is independent of DA signaling. Combining brain slice studies and site-directed mutagenesis in HEK293T cells, we found that cocaine binding to intracellular sigma-1 receptor (σ1) initiates this mechanism. Subsequently, σ1 binds to Kv1.2 potassium channels, followed by accumulation of Kv1.2 in the plasma membrane, thereby depressing NAcSh MSNs firing. This mechanism is specific to D1 receptor-expressing MSNs. Our study uncovers a mechanism for cocaine that bypasses DA signaling and leads to addiction-relevant neuroadaptations, thereby providing combinatorial strategies for treating stimulant abuse.

Abstract
The asymmetric cross-coupling reaction is developed as a straightforward strategy toward 1,1-diaryl alkanes, which are a key skeleton in a series of natural products and bioactive molecules in recent years. Here we report an enantioselective benzylic C(sp3)−H bond arylation via photoredox/nickel dual catalysis. Sterically hindered chiral biimidazoline ligands are designed for this asymmetric cross-coupling reaction. Readily available alkyl benzenes and aryl bromides with various functional groups tolerance can be easily and directly transferred to useful chiral 1,1-diaryl alkanes including pharmaceutical intermediates and bioactive molecules. This reaction proceeds smoothly under mild conditions without the use of external redox reagents. Chiral 1,1-diaryl alkanes are important targets in pharmaceutical industry. Here, the authors report report a redox-neutral enantioselective benzylic C−H bond arylation via photoredox/nickel dual catalysis accessing chiral 1,1-diarylalkane compounds under mild conditions.

Abstract
A new dinuclear zinc synergistic catalytic asymmetric phospha-Michael/Michael cascade reaction of o-dienones and dialkyl phosphates is reported. This method has been proven to be general and efficient for the formation of a range of chiral 1,2,3-trisubstituted indane compounds containing phosphorus groups in good yields (up to 92%) with excellent stereoselectivities (up to >99% ee and up to >99 : 1 dr). The relative configuration of the product was identified as having a trans,trans substitution pattern via two-dimensional (2D) nuclear Overhauser effect spectroscopy 1H-1H NMR experiments. A possible mechanism was proposed.

Abstract
Scavenging reactive oxygen species (ROS) by antioxidants is the important therapy to cerebral ischemia-reperfusion injury (CIRI) in stroke. The antioxidant with novel dual-antioxidant mechanism of directly scavenging ROS and indirectly through antioxidant pathway activation may be a promising CIRI therapeutic strategy. In our study, a series of chalcone analogues were designed and synthesized, and multiple potential chalcone analogues with dual antioxidant mechanisms were screened. Among these compounds, the most active 33 not only conferred cytoprotection of H2O2-induced oxidative damage in PC12 cells through scavenging free radicals directly and activating NRF2/ARE antioxidant pathway at the same time, but also played an important role against ischemia/reperfusion-related brain injury in animals. More importantly, in comparison with mono-antioxidant mechanism compounds, 33 exhibited higher cytoprotective and neuroprotective potential in vitro and in vivo. Overall, our findings showed compound 33 could emerge as a promising anti-ischemic stroke drug candidate and provided novel dual-antioxidant mechanism strategies and concepts for oxidative stress-related diseases treatment.

Abstract
A novel synthetic approach for the synthesis of bioactive phenolic natural products is reported. This strategy highlights the power of halogenative aromatization reactions recently developed in our group for preparing densely functionalized arenes in a controlled fashion. Five natural products related by an aromatic core and a farnesyl side chain are synthesized. In contrast to prior methods, this synthesis features high efficiency and generality that permits preparation of targets in gram-scale quantities.

Abstract
The current therapy for depression is less than ideal with remission rates of only 25-35% and a slow onset of action with other associated side effects. The persistence of anhedonia originating from depressed dopaminergic activity is one of the most treatment-resistant symptoms of depression. Therefore, it has been hypothesized that triple reuptake inhibitors (TRIs) with potency to block dopamine reuptake in addition to serotonin and norepinephrine transporters should produce higher efficacy. The current review comprehensively describes the development of TRIs and discusses the importance of evaluation of in vivo transporter occupancy of TRIs, which should correlate with efficacy in humans.

Abstract
A new approach for the synthesis of indatraline was developed using as the key step an iodine(III)-mediated ring contraction of a 1,2-dihydronaphthalene derivative. Behavioral tests were conducted to evaluate the effect of indatraline and of its precursor indanamide on the motor activity of Wistar rats. Specific indexes for ambulation, raising and stereotypy were computed one, two and three hours after i.p. drug administration. Indatraline effects on motor activity lasted for at least three hours. On the other hand, no significant differences in motor activity were observed using indanamide. The results suggest that indatraline has a long lasting effect on motor activity and add evidence in favor of the potential use of that compound as a substitute in cocaine addiction.

Abstract
The search for novel compounds of relevance to the treatment of diseases caused by trypanosomatid protozoan parasites continues. Screening of a large library of known bioactive compounds has led to several drug-like starting points for further optimisation. In this study, novel analogues of the monoamine uptake inhibitor indatraline were prepared and assessed both as inhibitors of trypanothione reductase (TryR) and against the parasite Trypanosoma brucei. Although it proved difficult to significantly increase the potency of the original compound as an inhibitor of TryR, some insight into the preferred substituent on the amine group and in the two aromatic rings of the parent indatraline was deduced. In addition, detailed mode of action studies indicated that two of the inhibitors exhibit a mixed mode of inhibition.

Abstract
Human cytomegalovirus (HCMV) is a widespread human pathogen, possessing onco-modulatory properties. Constitutive signaling of the HCMV-encoded chemokine receptor US28 and its ability to bind a broad spectrum of chemokines might facilitate HCMV-associated tumor progression. Novel nonpeptidergic chemotypes were identified as neutral antagonists or inverse agonists on US28, that allosterically inhibit chemokine binding to US28.

JOURNAL OF THE AMERICAN SOCIETY FOR MASS SPECTROMETRY 2009; 20:805-818.

Abstract
Upon CA, ESI generated [M + H](+) ions of chalcone (benzalacetophenone) and 3-phenyl-indanone both undergo losses of H(2)O, CO, and the elements of benzene. CA of the [M + H](+) ions of 2-methoxy and 2-hydroxychalcone, however, prompts instead a dominant loss of ketene. In addition, CA of the [M + H](+) ions of 2-methoxy-beta-methylchalcone produces an analogous loss of methylketene instead. Furthermore, the [M + D](+) ion of 2-methoxychalcone upon CA eliminates only unlabeled ketene, and the resultant product, the [M + D - ketene](+) ion, yields only the benzyl-d(1) cation upon CA. We propose that the 2-methoxy and 2-hydroxy (ortho) substituents facilitate a Nazarov cyclization to the corresponding protonated 3-aryl-indanones by mediating a critical proton transfer. The resultant protonated indanones then undergo a second proton transport catalysis facilitated by the same ortho substituents producing intermediates that eliminate ketene to yield 2-methoxy- or 2-hydroxyphenyl-phenyl-methylcarbocations, respectively. The basicity of the ortho substituent is important; for example, replacement of the ortho function with a chloro substituent does not provide an efficient catalyst for the proton transports. The Nazarov cyclization must compete with an alternate cyclization, driven by the protonated carbonyl group of the chalcone that results in losses of H(2)O and CO. The assisted proton transfer mediated by the ortho substituent shifts the competition in favor of the Nazarov cyclization. The proposed mechanisms for cyclization and fragmentation are supported by high-mass resolving power data, tandem mass spectra, deuterium labeling, and molecular orbital calculations.

Abstract
The development of radioligands suitable for studying the central nervous system (CNS) norepinephrine transporter (NET) in vivo will provide important new tools for examining the pathophysiology and pharmacotherapy of a variety of neuropsychiatric disorders including major depression. Towards this end, a series of trans-3-phenyl-1-indanamine derivatives were prepared and evaluated in vitro. The biological properties of the most promising compound, [(11)C]3-BrPA, were investigated in rat biodistribution and nonhuman primate PET studies. Despite high in vitro affinity for the human NET, the uptake of [(11)C]3-BrPA in the brain and the heart was not displaceable with pharmacological doses of NET antagonists.

Abstract
Binding assays for the norepinephrine (NE) transporter (NET) with [3H]nisoxetine have generally yielded weak potencies for compounds related to cocaine and 1-(2-(di(4-fluorophenyl)-methoxy)-ethyl)-4-(3-phenylpropyl)piperazine (GBR 12909), as compared with their functional activity in inhibiting NE uptake. In the present work with HEK-293 cells expressing the human NET (hNET), potential underlying causes for this discrepancy have been addressed: ambient temperature of the binding assay, buffer in the assay, preparation used for source of the NET, and radioligand. The results indicate that the standard [3H]nisoxetine binding assay at 0 degrees C with cell membrane preparations in high Na+ buffer underestimates the functional potency of compounds related to cocaine and GBR 12909; in drug development studies it is advisable to either carry out [3H]nisoxetine binding assays with intact cells under uptake conditions, or perform classical [3H]NE uptake studies with intact cells (or with synaptosomes from brain tissue).

Abstract
RATIONALE "Agonist" therapy for drug addiction proposes that a long acting analog, with similar properties to the abused substance might serve as a useful therapeutic agent. HD-23 is a very long acting tropane analog that displays a neurochemical profile similar to cocaine. OBJECTIVE To determine, using self-administration procedures and three different schedules of reinforcement, the effect of HD-23 on rate of cocaine intake (fixed ratio), the effect of HD-23 on the motivation to respond (progressive ratio) and the time course of HD-23 pretreatment (discrete trials). METHODS Male Sprague-Dawley rats were implanted with chronically indwelling intravenous cannulae and trained to self-administer cocaine (1.5 mg/kg per infusion) on a fixed ratio schedule. After a stable baseline was established, separate groups of rats ( n=6-8) were given access to various doses of cocaine (0.37, 0.75, 1.5 or 3.0 mg/kg per injection) on a fixed ratio schedule during daily 3-h sessions, or to various doses of cocaine (0.18, 0.37, 0.75, 1.5 mg/kg per injection) on a progressive ratio schedule during daily 5-h sessions. A separate group of rats ( n=10) was tested using a discrete trials procedure; animals were given the opportunity to self-administer cocaine (1.5 mg/kg per injection) during 10-min trials which were initiated every 20 min throughout the day/night cycle. RESULTS On the FR schedule, pretreatment with HD-23 (1.0 mg/kg) decreased the rate of cocaine intake. HD-23 shifted the dose-response curve on the PR schedule to the left. On the discrete trials schedule, animals displayed a circadian pattern of drug intake; pretreatment with HD-23 significantly increased cocaine intake for about 8 h during the light phase when the probability of responding would otherwise have been very low. Animals pretreated with HD-23 displayed a high probability of cocaine self-administration for about 14 h. CONCLUSIONS The results are consistent with the idea that an acute pretreatment with the long-acting agonist, HD-23, augmented rather than diminished the motivation to self-administer cocaine.

Abstract
A series of N-aromatic, N-heteroaromatic, and oxygenated N-phenylpropyl derivatives of 1-(2-benzhydryloxyethyl)-piperazine and 1-[2-[bis-(4-fluorophenyl)methoxy]ethyl]piperazine, analogues of GBR 12909 (1a) and 12935 (1b), was synthesized and examined for their dopamine (DAT) and serotonin (SERT) transporter binding properties. One of these compounds, racemic 3-[4-(2-benzhydryloxyethyl)piperazin-1-yl]-1-(3-fluorophenyl)-propan-1-ol (33), had DAT affinity as good as, or better than, GBR 12909 and 12935, and was more selective for DAT over SERT than the GBR compounds. Both trans- (43) and cis- (47) (+/-)-2-(4-[2-[bis-(4-fluorophenyl)-methoxy]ethyl]piperazin-1-ylmethyl)-6-methoxy-1,2,3,4-tetrahydronaphthalen-1-ol had relatively good SERT selectivity and, as well, showed high affinity for SERT.

Abstract
In a continuing effort to identify novel probes with which to study the dopamine transporter (DAT), we discovered that the sigma receptor antagonist, rimcazole, binds with moderate affinity (K(i)=224nM) to the DAT. The results from previous SAR studies suggested that substitution of the carbazole ring system of rimcazole with bis-(4'-fluorophenyl)amine might improve binding affinity and selectivity for the DAT. Thus, a novel series of [3-cis-3,5-dimethyl-(1-piperazinyl)alkyl]bis-(4'-fluorophenyl)amines were synthesized. The most potent compound in this series (9b) displaced [3H]WIN 35,428 binding in rat caudate-putamen (K(i)=17.6nM) with comparable affinity to GBR 12909. Despite high-affinity binding at DAT, and structural similarity to GBR 12909, preliminary studies suggest 9b behaves more like rimcazole than GBR 12909 and does not demonstrate cocaine-like psychostimulant behavior in mice.

Abstract
Amphetamine-type stimulants are substrates for the proteins that serve as transporters for the biogenic amines dopamine (DA), serotonin (5HT), and norepinephrine (NE) and release these neurotransmitters from neurons located in the peripheral and central nervous system. Using indatraline as a lead compound, we sought to develop a long-acting depot medication that would neutralize the deleterious effects of amphetamine-type stimulants. Our first efforts produced (+/-)-HY038, and its two stereoisomers, which are hydroxy-substituted analog of indatraline. The K(i) values for [(3)H]DA reuptake inhibition by (-)-HY038 and (+)-HY038 were 3.2 +/- 0.1 and 32 +/- 1 nM. Similar results were obtained for [(3)H]5HT reuptake inhibition. (-)-HY038 and (+)-HY038 were slightly less potent at inhibiting [(3)H]NE reuptake (K(i) values of 20 +/- 2 and 159 +/- 12 nM). Low doses of (-)-HY038 blunted the ability of AMPH to release [(3)H]DA by shifting the AMPH dose-response curve to the right in a dose-dependent manner. (-)-HY038 also inhibited the ability of (+)-methamphetamine and (+/-)-3,4-methylenedioxymethamphetamine ((+/-)-MDMA) to release [(3)H]DA. Low doses of (-)-HY038 blunted the ability of these stimulants to release [(3)H]NE and [(3)H]5HT by shifting their dose-response curves to the right in a manner similar to that seen for inhibition of [(3)H]DA release. These data indicate that (-)-HY038 inhibits the ability of AMPH, (+)-methamphetamine and (+/-)-MDMA to release DA, NE, and 5HT and therefore might have the potential to neutralize the neurotoxic and cardiovascular side-effects of substrate-type stimulants.
