Innovative therapeutic potential of cannabinoid receptors as targets in alzheimer?s disease and less well-known diseases

The discovery of cannabinoid receptors at the beginning of the 1990s, CB1 cloned in 1990 and CB2 cloned in 1993, and the availability of selective and potent cannabimimetics could only be justified by the existence of endogenous ligands that are capable of binding to them. Thus, the characterisation and cloning of the first cannabinoid receptor (CB1) led to the isolation and characterisation of the first endocannabinoid, arachidonoylethanolamide (AEA), two years later and the subsequent identification of a family of lipid transmitters known as the fatty acid ester 2-arachidonoylglycerol (2-AG). The endogenous cannabinoid system is a complex signalling system that comprises transmembrane endocannabinoid receptors, their endogenous ligands (the endocannabinoids), the specific uptake mechanisms and the enzymatic systems related to their biosynthesis and degradation. The endocannabinoid system has been implicated in a wide diversity of biological processes, in both the central and peripheral nervous systems, including memory, learning, neuronal development,32 stress and emotions, food intake, energy regulation, peripheral metabolism, and the regulation of hormonal balance through the endocrine system. In this context, this article will review the current knowledge of the therapeutic potential of cannabinoid receptor as a target in Alzheimer?s disease and other less well-known diseases that include, among others, multiple sclerosis, bone metabolism, and Fragile X syndrome. The therapeutic applications will be addressed through the study of cannabinoid agonists acting as single drugs and multi-target drugs highlighting the CB2 receptor agonist. 32.

Recent progress in the discovery and development of DNA gyrase B inhibitors

New antibacterials that modulate less explored targets are needed to fight the emerging bacterial resistance. DNA gyrase and topoisomerase IV are attractive targets in this search. These are both type II topoisomerases that can cleave both DNA strands, and can thus alter DNA topology during replication or similar processes. Currently, there are no ATP-competitive inhibitors of these two enzymes on the market, as the only aminocoumarin representative, novobiocin, was withdrawn due to safety concerns. The search for novel ATP-competitive inhibitors is a focus of ongoing industrial and academical research. This review summarizes the recent efforts in the design, synthesis and evaluation of GyrB/ParE inhibitors. The various approaches to achieve improved antibacterial activities are described, with particular reference to Gram-negative bacteria.

Thermal degradation of keratin waste

Thermal degradation of sheep wool, human hair and chicken feathers was studied by TG-MSD/FTIR and by pyrolysis followed by GC-MSD analysis in order to identify the degradation compounds and the temperature range in which they are formed. Only small differences were found between the studied keratin samples. They consist mainly in shift of characteristic temperatures of degradation and in relative amounts of compounds in degradation products, especially in aqueous phase. Degradation started with formation of ammonia and CO2 (from 167 and 197 C respectively and with maximum evolution at 273 and 287 C respectively), continues with formation of sulphur-containing inorganic compounds (SCS, SCO, H2S and SO2 at 240, 248, 255 and 253-260 C respectively) and of water (255 C). Thiols are formed in two stages (257 and 320 C) while the evolution of nitriles is maximum around 340 C and continues up to about 480 C. Phenol and 4-methylphenol are the most important degradation compounds, formed at 370 and 400 C respectively. Nitrogen was present mainly in aliphatic/aromatic nitriles, pyrroles, pyridines and amides while sulphur was found mainly as sulphides, thiols, thiazoles and thiophenes.

Volatile compounds of past?rma under different curing processes

The effects of different curing processes (curing temperature 4C or 10C and curing agent 150?mg/kg nitrite or 300?mg/kg nitrate) on the volatile compound profile of the past?rma (Turkish dry-cured meat product) have been investigated. A total of 45 volatile compounds, including alcohols, aldehydes, ketones, aliphatic and aromatic hydrocarbons, terpenes, sulphur compounds, esters, furans and nitrogenous compounds have been identified in past?rma samples. The curing temperature did not have a significant effect on any compound. The curing agent had statistically a significant or very significant influence on 12 compounds. In general, the use of nitrate increased the amount of volatile compound. However, lower mean hexanal value was determined in past?rma samples cured with nitrite than those cured with nitrate. Practical applications: Past?rma is a traditional dry-cured meat product. It is produced from whole muscle and/or mucsles of certain parts of beef or water buffalo carcasses. In curing stage, nitrate was used generally. However, nitrite can be used alone or with nitrate in this stage. In this study, the effects of different curing conditions (150?mg/kg nitrite or 300?mg/kg nitrate and 4C or 10C) on volatile compounds of past?rma were investigated. According to the results, past?rma produced with nitrate generally showed higher amounts of volatile compounds. On the other hand, curing temperature was not significant factor in terms of volatile compounds.

Pseudosaccharin amine derivatives: Synthesis and elastase inhibitory activity

Pseudosaccharin amines were synthesized from saccharin either by the reaction of pseudosaccharin chloride with amines, or via thiosaccharin which was treated with amines yielding thiosaccharinates, and their reaction with glacial acetic acid. This route gave lower yields than the first way. The synthesis of alkyl [(1,1-dioxo-benzo[d]isothiazol-3-yl)amino]alkanoates as possible Human Leukocyte Elastase (HLE) inhibitors was realized by the reaction between amino acid esters and pseudosaccharin chloride. Hydrolysis of the esters was possible under aqueous basic conditions. Selected compounds were screened for elastase inhibitory activity. Compounds 4k and 4m were found to be reversible inhibitors of HLE with Ki values of 45 muM and 60 muM.

A 15N NMR Study of Some Azoles

15N NMR data are reported for 42 azoles, taken mostly at a standard concentration and in a common solvent (0.5 M dimethyl sulfoxide with a 0.01 M increment of Cr(acac)3 for each nitrogen atom present).Signal assignments were assisted by comparison with 14N line widths, the use of 2J(15N1H) couplings, and shielding calculations obtained by the INDO/S-SOS approach.The generally large differences in nitrogen-shielding changes permitted rather facile shift assignments.

New disulfide route to 3-(1-piperazinyl)-1,2-benzisothiazole. Nucleus for atypical antipsychotic drugs

A new, one-step commercial process for the preparation of 3-(1-piperazinyl)-l,2-benzisothiazole hydrochloride, a key intermediate for the syntheses of some new, “atypical antipsychotic” drugs, was developed. Reaction of bis(2-cyanophenyl) disulfide with excess piperazine at 120-140 C for 3-24 h in the presence of small amounts of DMSO and 2-propanol formed 3-(l-piperazinyl)-l,2-benzisothiazole in 75-80% yields. The DMSO oxidized the liberated 2-mercaptobenzonitrile to regenerate bis(2-cyanophenyl) disulfide, thereby enabling the utilization of both halves of the symmetrical disulfide to generate product. The reaction mechanism for the conversion of the bis(2-cyanophenyl) disulfide to 3-amino-1,2-benzisothiazole involves the formation of ring-opened sulfenamide and benzamidine intermediates and then their subsequent ring closure to regenerate the 1,2-benzisothiazole nucleus. A safe, efficient, and robust process to prepare 3-(l-piperazinyl)-1,2-benzisothiazole under very concentrated reaction conditions was developed and successfully scaled up in the pilot plant to support the development of ziprasidone.

Lurasidone: efficacy and safety in the treatment of psychotic and mood disorders

Introduction: Lurasidone ([3aR,4S,7R,7aS]-2-[(1R,2R)-2-[4-(1,2-benzisothiazol-3-yl)piperazin-1yl-methyl] cyclohexylmethyl]-hexahydro-4,7-methano-2H-isoindole-1,3-dione hydrochloride; Latuda) is a novel benzisothiazole, second-generation antipsychotic drug developed by Dainippon Sumitomo Pharma Corporation in Japan. Similar to other atypical antipsychotics it has a distinctive pharmacodynamic profile, Areas covered: This review updates reported research findings on the efficacy, safety and tolerability of LRSD for treatment of psychotic and major affective disorders, with meta-analyses. Short-term efficacy of LRSD in schizophrenia is supported by several randomized, controlled trials with daily doses of 40?160?mg, yielding relatively modest symptomatic improvements. Lurasidone has regulatory approval for treatment of undefined duration in schizophrenia. Long-term benefits and effects in schizophrenia, and both short- and long-term use for other psychotic disorders and mania have not been tested. LRSD shows unusual efficacy in acute bipolar depression even without psychotic features. However, trials of adding LRSD to lithium or valproate for bipolar disorder have yielded inconsistent findings. Expert opinion: Available research findings indicate that LRSD is effective and well-tolerated for short-term treatment of schizophrenia, and for acute bipolar depression. It has low risk of inducing weight-gain, metabolic, or cardiac abnormalities, but its risk of akathisia may exceed that of other modern antipsychotics. Needed is adequate long-term testing in schizophrenia and bipolar disorder and testing for other indications, including against alternative treatments.

Continuation of structure?activity relationship study of novel benzamide derivatives as potential antipsychotics

A series of benzamide derivatives possessing potent dopamine D2, serotonin 5-HT1A, and 5-HT2A receptor properties were synthesized and evaluated as potential antipsychotics. Among them, 5-(4-(4-(benzo[d]isothiazol-3-yl)piperazin-1-yl)butoxy)-N-cyclopropyl-2-fluorobenzamide (4k) held the best pharmacological profile. It not only exhibited potent and balanced activities for the D2, 5-HT1A, and 5-HT2A receptors, but was also endowed with low to moderate activities for the 5-HT2C, H1, and M3 receptors, suggesting a low propensity for inducing weight gain or diabetes. In animal models, compound 4k reduced phencyclidine-induced hyperactivity with a high threshold for catalepsy or muscle relaxation induction. On the basis of its robust in vitro potency and in vivo efficacy in preclinical models of schizophrenia, 4k was selected as a candidate for further development.
