An ammonium ylide mediated access towardstrans-beta,gamma-disubstituted,all-trans-alpha,beta,gamma-trisubstituted, and alpha,alpha,beta,gamma-tetrasubstituted gamma-butyrolactones bearing a broad variety of functionalities was developed. Starting from widely accessible benzylidene Meldrum’s acid derivatives and alpha-bromo carbonyl compounds,gamma-butyrolactones were obtained in yields between 32-99% with up to excellent diastereoselectivities (>95:5)viaa DABCO-mediated [2+1] annulation. Utilization of enantiomerically pure cinchona alkaloid derivatives enables the first asymmetric ammonium ylide mediated method to provide (3R, 4R)-beta,gamma-disubstituted and (2R, 3R, 4R)-alpha,beta,gamma-trisubstituted gamma-butyrolactones in moderate to good yields with up to very good enantiomeric ratios (97:3). The scalability of the transformation was proven while determining the absolute configuration.

Background Evidence on longitudinal variability of serum uric acid (SUA) and risk of all-cause mortality in the general population is limited, as many prior studies focused on a single measurement of SUA. Methods A total of 53,956 participants in the Kailuan study who underwent three health examinations during 2006 to 2010 were enrolled. Variability of SUA was measured using the coefficient of variation (primary index), standard deviation, average real variability, and variability independent of the mean. Cox proportional hazard regressions were used to calculate the hazard ratio (HR) and 95% confidence interval (CI) for the association of variability of SUA with subsequent risk of all-cause mortality, considering its magnitude and the direction and across different baseline SUA categories. Results Over a median follow-up of 7.04 years, 2728 participants died. The highest variability of SUA was associated with an increased risk of all-cause mortality, the HR was 1.33 (95% CI, 1.20-1.49) compared with the lowest variability. In this group, both a large fall (HR, 1.28; 95% CI, 1.14-1.44) and rise (HR, 1.18; 95% 1.05-1.32) in SUA were related to risk of all-cause mortality. These associations were similar across different baseline SUA categories. Consistent results were observed in alternative measures of SUA variability. Moreover, individuals with higher variability in SUA were more related to common risk factors than those with stable SUA. Conclusions Higher variability in SUA was independently associated with the risk of all-cause mortality irrespective of baseline SUA and direction of variability in the general population.

Serotonergic psychedelics, substances exerting their pharmacological action through activation of the serotonin 2A receptor (5-HT2AR), have continuously comprised a substantial fraction of the over 1000 reported New Psychoactive Substances (NPS) so far. Within this category, N-benzyl derived phenethylamines, such as NBOMes and NBFs, have shown to be of particular relevance. As these substances remain incompletely characterized, this study aimed at synthesizing positional isomers of 25H-NBF, with two methoxy groups placed on different positions of the phenyl group of the phenethylamine moiety. These isomers were then functionally characterized in an in vitro bioassay monitoring the recruitment of beta-arrestin 2 to the 5HT(2A)R through luminescent readout via the NanoBiT technology. The obtained results provide insight into the optimal substitution pattern of the phenyl group of the phenethylamine moiety of N-benzyl derived substances, a feature so far mostly explored in the phenethylamines underived at the N-position. In the employed bioassay, the most potent substances were 24H-NBF (EC50 value of 158 nM), 26H-NBF (397 nM), and 25H-NBF (448 nM), with 23H-NBF, 35H-NBF, and 34H-NBF yielding mu M EC50 values. A similar ranking was obtained for the compounds’ efficacy: taking as a reference LSD (lysergic acid diethylamide), 24H-, 26H-, and 25H-NBF had an efficacy of 106-107%, followed by 23H-NBF (96.1%), 34H-NBF (75.2%), and 35H-NBF (58.9%). The stronger activity of 24H-, 25H-, and 26H-NBF emphasizes the important role of the methoxy group at position 2 of the phenethylamine moiety for the in vitro functionality of NBF substances.

Pyrrolizidine alkaloids (PAs) and their corresponding N-oxides (PANOs) have been determined in food and feed at levels relevant for consumer health. More than 660 different PAs have been detected, but few are available as reference substances for analytical demands. In the context of the European legislation on maximum levels of PAs in food products, a defined analytical scope of 21 PAs for determination has been suggested. An expansion of the scope from 21 to 35 PAs, including 14 structural isomers, is currently under discussion. In the present study, a target screening method was established for a comprehensive characterisation of PA profiles of the species Echium vulgare, Heliotropium europaeum, Cynoglossum officinale and Symphytum spp. to assess whether an expansion of the analytical scope is required to quantitatively cover the total PA contents of Boraginaceae species. The scope of the method comprised known and unknown PAs previously screened and confirmed in the respective plant extracts. A total of 176 PAs and PANOs were detected. The toxic 1,2-unsaturated PAs represent the predominant PA type with about 98% of the mean total content. This PA profiling demonstrates that an expansion of the scope from 21 to 35 PAs is required to adequately cover the mean total PA contents of Cynoglossum officinale and H. europaeum, whereas in the case of Symphytum spp. and Echium vulgare an expansion would not be necessary.

Six novel 2-arylimidazo[2,1-b]benzothiazole (IBT) derivatives were synthesized as potential tridentate radiotracers for AD imaging purposes. Two of these ligands (6a,b) were successfully labeled with Tc-99m radionuclide at high radiochemical purity using fac-(Tc-99(m)(CO)(3)(H2O)(3)](+) synthon. [Tc-99m]7a and [Tc-99m]7b were evaluated as single photon emission computed tomography (SPECT) imaging agents for A beta plaque in AD. [Tc-99m]7a and (Tc-99m]7b exhibited suitable affinity toward A beta aggregates with IC50 values of 33.2 and 102.5 nM, respectively. The IC50 value of these radiotracers depends on the length of the spacer (alkyl chain). In biodistribution study, these complexes showed good initial brain uptakes (0.78 and 0.86% ID/g at 2 min post-injection) and fast blood clearance. Autoradiography results confirmed that these small Tc-99m complexes (Mw about 600 Da) can bind to A beta plaques in the brain sections of the rat AD model. Histopathological staining with Congo red approved the presence of A beta plaques in these brain sections. (C) 2019 Elsevier Masson SAS. All rights reserved.

1. We investigated the structure-activity relationship of 31 kinds of synthesized atorvastatin esters, thioesters, amides and lactone, selected as prodrug models, for metabolic activation by microsomes and hydrolases. 2. The susceptibility to human carboxylesterase 1 (hCES1) was influenced not only by the size of the acyl group and alkoxy group but also by the degree of steric crowding around the alkoxy group. 3. The susceptibility to human carboxylesterase 2 (hCES2) increased with a decrease in electron density around the alkoxy group of the substrate. 4. Lactone was specifically hydrolyzed by paraoxonase 3 (PON3). 5. These findings should be useful in prodrug design for controlling metabolic activation.

Herein we describe the synthesis of five new 2-aryl and 2-alkylimidazolone derivatives via an effective one-pot synthetic strategy assisted by microwave irradiations which allowed us to access the desired product in a reduced time reaction compared to the thermal heating and a slightly better yield (48% compared to 45%). The new imidazolone derivatives were evaluated for their anticancer activity in vitro against MCF-7, MDA-MB-231 and HepG2 cell lines. The results showed good cytotoxic effects for some of these derivatives on both MCF-7 and HepG2 cell lines in the range of 5.7-11.3 mu M. Among the synthesized derivatives, 2ab and 2b showed the strongest activity with IC50 values of 7 and 5.7 mu M (MCF-7) and 6.2 and 8.6 mu M (HepG2), respectively. The cytotoxic activities of these derivatives were moderate compared to those of doxorubicin. However, this product showed higher toxicity in vivo on the development of zebrafish embryos than the synthesized imidazolones. These derivatives at high concentrations exhibited some morphological abnormalities on the embryos.

Metabolites can distinguish pathogenic from healthy cells, but they are hard to couple to current photosensitizers without altering their biological activity. Here the authors design a new family of photosensitizers that retain metabolite function to target pathogenic cells and ablate them by photodynamic therapy. Photoactivatable molecules enable ablation of malignant cells under the control of light, yet current agents can be ineffective at early stages of disease when target cells are similar to healthy surrounding tissues. In this work, we describe a chemical platform based on amino-substituted benzoselenadiazoles to build photoactivatable probes that mimic native metabolites as indicators of disease onset and progression. Through a series of synthetic derivatives, we have identified the key chemical groups in the benzoselenadiazole scaffold responsible for its photodynamic activity, and subsequently designed photosensitive metabolic warheads to target cells associated with various diseases, including bacterial infections and cancer. We demonstrate that versatile benzoselenadiazole metabolites can selectively kill pathogenic cells – but not healthy cells – with high precision after exposure to non-toxic visible light, reducing any potential side effects in vivo. This chemical platform provides powerful tools to exploit cellular metabolic signatures for safer therapeutic and surgical approaches.

Purpose To investigate the association between vision and hearing impairment and falls in community-dwelling adults aged >= 50 years. Methods This is a prospective study on 50,986 participants assessed in Waves 6 and 7 of the Survey of Health, Ageing and Retirement in Europe. At baseline, we recorded socio-demographic data, clinical factors and self-reported vision and hearing impairment. We classified participants as having good vision and hearing, impaired vision, impaired hearing or impaired vision and hearing. We recorded falls in the six months prior to the baseline and 2-year follow-up interviews. The cross-sectional and longitudinal associations between vision and hearing impairment categories and falls were analysed by binary logistic regression models; odds ratios (OR) and 95% confidence intervals (CI) were calculated. All analyses were adjusted for socio-demographic and clinical factors. Results Mean age was 67.1 years (range 50-102). At baseline, participants with impaired vision, impaired hearing, and impaired vision and hearing had an increased falls risk (OR (95% CI)) of 1.34 (1.22-1.49), 1.34 (1.20-1.50) and 1.67 (1.50-1.87), respectively, compared to those with good vision and hearing (all p < 0.001). At follow-up, participants with impaired vision, without or with impaired hearing, had an increased falls risk of 1.19 (1.08-1.31) and 1.33 (1.20-1.49), respectively, compared to those with good vision and hearing (both p < 0.001); hearing impairment was longitudinally associated with falls in middle-aged women. Conclusion Vision impairment was cross-sectionally and longitudinally associated with an increased falls risk. This risk was highest in adults with dual sensory impairment. Key summary pointsAim To investigate the relationship between self-reported vision and hearing impairment and falls risk in community-dwelling adults aged >= 50 years in the cross-national Survey of Health, Ageing and Retirement in Europe (SHARE). Findings Self-reported vision impairment, versus no impairment, was cross-sectionally and longitudinally associated with an increased falls risk in adults, independent of age, sex, self-rated health, co-morbidities and medications. The risk was highest when vision and hearing impairment coincided. Message Simple questions on self-reported sensory impairment can be used to assess the risk of falls in adults.
