Identification of 2-aminopyrimidine derivatives as inhibitors of the canonical Wnt signaling pathway

The canonical Wnt signaling pathway plays a fundamental role in embryonic as well as in adult development. Consequently, dysregulation of the pathway has been linked to a wide spectrum of pathological conditions. In a program aimed at the identification of small molecule inhibitors of the canonical Wnt pathway we identified a series of 2-aminopyrimidine derivatives which specifically inhibited the pathway with minimal or no sign of cellular toxicity. The hit molecules 1 and 2 showed promising inhibitory activity with IC50 values of approximately 10 muM, but low solubility and metabolic stability. During the early stage of the hit series exploration, the pyrimidine core was variously decorated to obtain active compounds with a better physico-chemical profile. In particular, compound 13 showed Wnt inhibition activity comparable to hit molecules 1 and 2, with improved physico-chemical properties. Therefore, this series of compounds may be considered a promising starting point for the design of novel small molecule inhibitors of the canonical Wnt pathway.

Recent therapeutic progress of chalcone scaffold bearing compounds as prospective anti-gout candidates

Gout is a common form of arthritis characterized by severe and sudden pain for a long duration, swelling, tenderness, lingering discomfort, and acute redness in the joint situated at the big toe due to the accumulation of monosodium urate (MSU) crystals. Though, at present these drugs have limited pharmacodynamics benefits with the emergence of adverse effects. Therefore, the modern trend has perceived a shift towards the regular use of natural products and tailored-approach, which have revolutionized the prescription pattern from traditional combinations to unexplored classes of drugs. Natural product classes such as chalcones have received adequate attention for treating these severe ailments with a better margin of safety. Chalcone or 1,3-diphenyl-2-propene-1-one or benzylideneacetophenone are the natural scaffold comprising of two aromatic rings connected together by a three-carbon alpha, beta unsaturated carbonyl link. The chalcone scaffold bearing synthetic (polyhydroxylated chalcones, 3,5,2,4-tetrahydroxychalcone, trans-chalcone) and natural (sappanchalcone, okanin, hesperidin methylchalcone, quercetin chalcone, 4-hydroxyderricin, isobavachalcone, xanthoangelol F, xanthoangelol, and xanthoangeleol B) compounds have been found to exhibit tremendous anti-gout activity by completely suppressing the active disease proliferating enzyme, xanthine oxidase (XO) as well as by suppressing the activation of nuclear factor kappa-light-chain-enhancer of activated B cells (NF-kappabeta), along with preventing the formation and influx of pro-inflammatory factors. The overview glance of this scientific review will provide information to the scientists working in the pharmaceutical as well as allied science fields in fabricating, screening, and exploring the abundant hidden chemical classes based on the provided structural, chemical, and miscellaneous aspects.

Pharmaceuticals of emerging concern in aquatic systems: Chemistry, occurrence, effects, and removal methods

In the last few decades, pharmaceuticals, credited with saving millions of lives, have emerged as a new class of environmental contaminant. These compounds can have both chronic and acute harmful effects on natural flora and fauna. The presence of pharmaceutical contaminants in ground waters, surface waters (lakes, rivers, and streams), sea water, wastewater treatment plants (influents and effluents), soils, and sludges has been well doccumented. A range of methods including oxidation, photolysis, UV-degradation, nanofiltration, reverse osmosis, and adsorption has been used for their remediation from aqueous systems. Many methods have been commercially limited by toxic sludge generation, incomplete removal, high capital and operating costs, and the need for skilled operating and maintenance personnel. Adsorption technologies are a low-cost alternative, easily used in developing countries where there is a dearth of advanced technologies, skilled personnel, and available capital, and adsorption appears to be the most broadly feasible pharmaceutical removal method. Adsorption remediation methods are easily integrated with wastewater treatment plants (WWTPs). Herein, we have reviewed the literature (1990-2018) illustrating the rising environmental pharmaceutical contamination concerns as well as remediation efforts emphasizing adsorption.

Oxidation of sulfamethoxazole by UVA radiation and modified Fenton reagent: Toxicity and biodegradability of by-products

Improvement of sulfamethoxazole (4-amino-N-(5-methylisoxazol-3-yl)- benzenesulfonamide – SMX) biodegradability using a modified Fenton’s reaction has been studied. The modification consists of replacing hydrogen peroxide with atmospheric air and adding copper sulphate as a reaction promoter. Two series of experiments were carried out. The first (Series 1) was conducted using only the catalysts with aeration. In the second series (Series 2), cycles of UVA radiation and aeration were used. During UVA radiation, the removal of sulfamethoxazole proceeds less rapidly than in only aerated solution. After 1.5 h of these two processes, the SMX degradation was 23% in Series 2 and 59% in Series 1. The opposite trend was observed for mineralization and the removal of DOC was about 5% higher in Series 2 than in Series 1. The FTIR spectra of the extracts of reaction products yielded by four organic solvents of varying polarity revealed a wide diversity of functional groups in the post-reaction mixture in comparison to the extracts from sulfamethoxazole solution. Based on FTIR analysis, several oxidation products of sulfamethoxazole are proposed. Apparently, hydroxyl radicals initially attack sulphonamide bonds, resulting in the formation of sulfanilic acid and 3-amino-5-methylisoxazole. Irrespective of the reference organism used in toxicity tests, the post-reaction mixture in the Series 2 was more toxic than the post-reaction mixture in Series 1. In contrast, the biodegradability calculated as BOD5/DOC ratio, was higher for post-reaction mixture 2 and amounted to 0.43. IWA Publishing 2009.

A novel strategy of successive non-radical and radical process for enhancing the utilization efficiency of persulfate

During the process of persulfate oxidation, side reactions such as the recombination of radicals can usually result in the low utilization efficiency of persulfate, which decreases the mineralization of target pollutants. In this study, the successive oxidation strategy was proposed based on successive non-radical and radical process (SNRP), to enhance the utilization efficiency of peroxymonosulfate (PMS), and further enhance the mineralization of sulfonamides. The results indicated that 0.04 mM of sulfonamide could be completely removed within 240 min at 1.2 mM PMS and initial pH 6.8 in the non-radical process, but the mineralization was very low (<2%). Moreover, the decomposition efficiency of PMS was less than 10% within 480 min. Fe(II) was added into the solution in which non-radicals process was performed, to initiate radical process by activating residual PMS. Compared to Fe(II)/PMS process, the SNRP process significantly increased the mineralization of sulfonamides, reaching 27.0%, 19.0%, 16.7% and 17.2%, respectively for sulfamethoxazole, sulfanilamide, sulfadiazine and sulfamerazine. The increased mineralization was due to the enhanced PMS utilization. Seven degradation products were identified in the SNRP process. Among them, hydrolyzed 3-amino-5-methyl isoxazole, (3-amino-5-methylisoxazole) sulfonic acid and 4-aminobenzenesulfinic acid produced in the non-radical oxidation process showed resistance to the subsequent radical oxidation. This study can provide a possible way to enhance the utilization efficiency of PMS as well as the mineralization of organic pollutants. I hope this article can help some friends in scientific research.

Decisive properties of solvent able to form gels with syndiotactic polystyrene

The thermoreversible gel formation of syndiotactic polystyrene (SPS) was studied in detail. Even if SPS solutions with high concentrations did not form gels, there were the cases where SPS formed gels at lower concentrations of SPS, which favor the formation of a polymer-solvent molecular compound. Sixty-two solvent compounds were examined in regard to whether they could form SPS gels. All the compounds whose molecular volume is between 69 and 153 A3 and whose Fedors’ solubility parameter value is between 8.8 and 12.3 (cal/cm3)1/2 were found to produce SPS gels as solvent. Since a solvent molecule that can form SPS gel can be a guest of SPS delta co-crystalline phase, it has become convenient to find functional molecules able to co-crystallize with SPS by taking into account these conditions of gelation solvent molecules.

Intermolecular hydrogen bonding interactions of furan, isoxazole and oxazole with water

Intermolecular hydrogen bonding between furan, isoxazole, oxazole and water has been analysed using theoretical methods. Ab initio and DFT methods have been employed to optimize the adducts of heterocycles with single water molecule. The stabilization energies associated with the adduct formation are evaluated at B3LYP/AUG-cc-pVDZ//B3LYP/6-31+G*, MP2/AUG-cc-pVDZ//MP2/6-31+G* levels and corrected for zero-point vibrational energies (ZPE) and basis set superposition error (BSSE) using counterpoise method. Natural bond orbital analysis (NBO) at MP2/6-31+G* has also been carried out to study electron delocalization of these adducts. The hydrogen bond acceptor ability of heteroatoms and p cloud of the ring are compared. In the heterocyclic molecules with nitrogen and chalogen in 1, 2 and 1, 3 positions, the nitrogen is better hydrogen bond acceptor than the chalcogen in all cases.
