Synthesis and pharmacological evaluation of potent and highly selective D3 receptor ligands: Inhibition of cocaine-seeking behavior and the role of dopamine D3/D2 receptors

The synthesis, pharmacological evaluation, and structure – activity relationships (SARs) of a series of novel arylalkylpiperazines structurally related to BP897 (3) are described. In binding studies, the new derivatives were tested against a panel of dopamine, serotonin, and noradrenaline receptor subtypes. Focusing mainly on dopamine D3 receptors, SAR studies brought to light a number of structural features required for high receptor affinity and selectivity. Several heteroaromatic systems were explored for their dopamine receptor affinities, and combinations of synthesis, biology, and molecular modeling, were used to identify novel structural leads for the development of potent and selective D3 receptor ligands. Introduction of an indole ring linked to a dichlorophenylpiperazine system provided two of the most potent and selective ligands known to date (D 3 receptor affinity in the picomolar range). The intrinsic pharmacological properties of a subset of potent D3 receptor ligands were also assessed in [35S]-GTPgammaS binding assays. Evidence from animal studies, in particular, has highlighted the dopaminergic system’s role in how environmental stimuli induce drug-seeking behavior. We therefore tested two novel D3 receptor partial agonists and a potent D 3-selective antagonist in vivo for their effect in the cocaine-seeking behavior induced by reintroduction of cocaine-associated stimuli after a long period of abstinence, and without any further cocaine. Compound 5g, a nonselective partial D3 receptor agonist with a pharmacological profile similar to 3, and 5p, a potent and selective D 3 antagonist, reduced the number of active lever presses induced by reintroduction of cocaine-associated stimuli. However, 5q, a highly potent and selective D3 partial agonist, did not have any effect on cocaine-seeking behavior. Although brain uptake studies are needed to establish whether the compounds achieve brain concentrations comparable to those active in vitro on the D3 receptor, our experiments suggest that antagonism at D2 receptors might significantly contribute to the reduction of cocaine craving by partial D3 agonists.

Characterisation of organic matter in sediment from Corin Reservoir, Australia

Analytical pyrolysis was performed to characterise the organic matter present in sediments from Corin Reservoir, a major water supply for Canberra, Australia. Pyrolysis of the whole sediment yielded furans, methoxyphenols, aliphatic products and nitrogenous compounds that are indicative of carbohydrates, lignin, lipids and proteins respectively. There was a decrease in the observed relative peak area of polysaccharide and lignin-derived marker compounds with increasing depth of sediment and an increase in nitrogenous marker compounds. In addition, eucalyptol, a molecular marker compound characteristic of eucalyptus – the dominant vegetation of the surrounding catchment – was detected.

High resolution accurate mass multi-class multi-residue screening method for the analysis of honey samples collected from various parts of Kerala state, India using LC-QTOF

A sensitive and specific liquid chromatography-electrospray ionization high resolution mass spectrometry (LC/ESI-HRMS) method was developed for the multi-class multi-residue screening of eight natural source honey samples collected from various locations of Kerala State, India. A generic sample extraction protocol based on liquid-liquid extraction (LLE) was employed. Minimal LC separation by a generic gradient program based on reverse phase chromatography was developed. Single injection workflow using TOF-MS survey scan followed by dependent TOF-MS/MS scans was used for the simultaneous screening, identification and confirmation of pesticide and antibiotic residues. High resolution TOF MS/MS data generated by Auto MS/MS workflow was also used for LC -MS/MS mass spectral library search. Honey samples collected from natural sources were considered to be safe for consumption; however, screening of eight honey samples indicates presence of pesticides; pharmaceuticals, degradation products, mycotoxins and veterinary antibiotics. Presence of identified compounds in the sample is confirmed by matching the obtained fragmentation pattern with insilico fragments generated by the structure of compounds. Present study also confirms that same workflow can be used for identification and confirmation of totally unknown compounds present in the honey samples. Developed method is validated by running mixed aqueous standards of pesticides and antibiotics as well as matrix matched quality control samples.

CO2 gasification in a dual fluidized bed reactor system: Impact on the product gas composition

The use of CO2 as gasification agent in the 100 kWth dual fluidized bed gasification pilot plant was investigated at TU Wien. For this purpose, steam was replaced stepwise by CO2 as gasification agent. Softwood was used as fuel and olivine as bed material. Starting from 100 vol.-% steam as gasification agent, substituting it by 32, 45 and finally 68 vol.-% CO2. All loop seals were fluidized further with steam, which resulted in these volume percentages. Additionally, a CO2 gasification test campaign converting softwood with a mixture (90/10 wt.-%) of olivine and limestone was investigated. For this case, the gasification agent was composed of 65 vol.-% CO2 and 35 vol.-% steam. The use of CO2 as gasification agent led to changes of the product gas. Instead of a H2-enriched product gas, which was produced during steam gasification, CO and CO2 occupied the major share of the product gas. Consequently, the H2/CO ratios as well as the lower heating values decreased when substituting steam by CO2. Tar contents were lower for CO2/steam gasification compared to pure steam gasification.

One-pot three-component reactions of methyl ketones, phenols and a nucleophile: An expedient way to synthesize densely substituted benzofurans

Three-component reactions of phenylglyoxal monohydrate, phenols, and indoles were developed with the aid of acid-catalyst, which produced various densely substituted benzofurans with good to excellent yields. On the basis of this observation, a one-pot, step-wise reaction was developed by using methyl ketones instead of using phenylglyoxal component in I2/DMSO system. At last, three-component reaction offered a useful way to synthesize densely substituted benzofurans starting from simple and easily available substrates. The indole component can be replaced by some other nucleophiles, such as 1,2,4-trimethoxybenzene and thiophenol.
