Seven new compounds including three pairs of enantiomeric xanthine analogues (1-3), a pair of enantiomeric hypoxanthine analogue (4), and three pairs of enantiomeric N-acetyldopamine dimers (6-8), together with a known one (5) were isolated from the insect Cyclopelta parva. Their structures including absolute configurations were assigned by using spectroscopic and computational methods. Chiral HPLC was used to separate racemic 1-8. Biological evaluation found that 6b and 7a are potent COX-2 inhibitory agents with IC50 values at 385.2 nM and 868.8 nM respectively. An efficient, microwave-assisted, oxidant-interceded, transition-metal-free, cross-dehydrogenative Csp2-Csp3 coupling of C8-Caffeine 2/Theobromine 3/theophylline 4 with substituted aliphatic alcohols 11a-lvia CH bond activation for the preparation of series of substituted C8-(hydroxymethyl) Caffeine 12a-l/theobromine 13a-c/theophylline 14a-b has been developed using microwave irradiation upto 98% yield. The reaction proceeds smoothly in the presence of tert-butyl hydroperoxide (TBHP) under solvolysis condition at 120 °C for 20 min to corresponding substituted C8-(hydroxymethyl)-methylxanthine derivatives in good to excellent yields. The good substrate scope, control experiments, gram-scale synthesis, and practical synthetic transformations further highlights the practicality of this methodology. These C8-(hydroxymethyl) Caffeine 12a-l, 13a-c and 14a-b have been found to show promising in vitro antioxidant as well as antiplatelet activities. Crataegus (Rosaceae; hawthorn), are small trees that grow in the Northern Hemisphere. Plant materials of Crataegus show promising benefits in adjunctive treatment of cardiovascular disorders, primarily attributed to flavonoids and other phenolic derivatives. 1H NMR was used in quantification of four flavonoids (naringenin, hyperoside, rutin, and vitexin-2″-O-rhamnoside) and chlorogenic acid in leaf extracts of four Crataegus species. The data were validated by comparison to HPLC-DAD. Vitexin and its derivatives were significantly more concentrated in the European (C. monogyna and C. laevigata) leaves and rutin significantly more concentrated in the North American (C. douglasii and C. okanaganensis) leaves. BAY 2402234 solubility dmso The concentrations of rutin and naringenin reported in this study are the highest reported for Crataegus. This work represents the first quantitative report of flavonoids in the North American hawthorns C. douglasii and C. okanaganensis and a direct comparison with the common European species. Three new homoadamantane-type polyprenylated acylphloroglucinols, hyperacmosins E-G (1-3), with seven known compounds were isolated from the air-dried aerial parts of Hypericum asmosepalum. Their structures were determined by NMR, HRESIMS and experimental electronic circular dichroism (ECD) spectra. The hepatoprotective activity of these compounds were evaluated. Compounds 4 and 8 exhibited hepatoprotective activity against paracetamol-induced HepG2 cell damage. Commiphoins A-C (1-3), three new cadinane-type sesquiterpenes, together with two known cadinane-type sesquiterpenes (4 and 5) were isolated from the resinous exudates of Commiphora myrrha. Their structures and relative configurations were established on the basis of comprehensive spectroscopic methods, including HRESIMS, 1D and 2D NMR analyses. Compounds 1 and 3-5 were screened for anti-Alzheimer's disease (AD) activities using the AD pathological model in Caenorhabditis elegans. The results showed that they all had significant anti-AD activities. Dyslexic children present poorer postural control performance than their peers, perhaps due to different patterns of eye movements. It has been shown that guided eye movements decrease magnitude of body sway in young and older adults, but there is no evidence whether the search for visual information that occurs during eye movements affects postural control in dyslexic children. The aim of this study was to examine the use of guided eye movements and its pattern in the performance of postural control of dyslexic children during upright quiet stance. Twelve children with dyslexia (10.8 ± 1.1 years old) and 12 non-dyslexic children (10.4 ± 1.5 years old) participated in this study. All children were instructed to maintain an upright quiet stance for 60 s either fixating on a target (fixation condition) displayed 1 m ahead in the center of a monitor at eye level, or performing eye movements to follow a target displayed on one side of a monitor, then disappearing and reappearing immediately on the opposite side woor performance of postural control in dyslexic children. OBJECTIVE Sex plays an important role in many diseases. The purpose of current study is to explore whether there are different lesion patterns in the RSN functional connections between males and females with MCI progression, and identify the differences in brain network changes due to sex. METHODS Resting state fMRI data included 37 normal controls (NC), 39 early MCI (EMCI) patients and 37 late MCI (LMCI) patients were collected, and network model based on graph theory was performed to compare the differences of brain network at different stages caused by sex from three aspects functional connectivity between ROIs, intra-functional connectivity within RSN and inter-functional connectivity between RSN and white matter (WM). RESULTS Sex plays a role in the changes of RSN functional connectivity, including the default mode network (DMN), the sensory-motor network (SMN), the dorsal attention network (DAN) and the executive control network (CON). The female SMN is more vulnerable and the damage of functional connectivity between DAN and WM is more serious. CONCLUSIONS There are different lesion patterns in the RSN functional connections between males and females in the progression of MCI, which suggests that we should take full account of sex differences when conducting MCI progress studies and developing more effective biomarkers to promote the progress of cognitive impairment and dementia. According to investigations in phytomedicine and ethnopharmacology, the therapeutic properties of garlic (Allium sativum) have been described by ancestral cultures. Notwithstanding, it is of particular concern to elucidate the molecular mechanisms underlying this millenary empirical knowledge. Allicin (S-allyl prop-2-ene-1-sulfinothioate), a thioester of sulfenic acid, is one of the main bioactive compounds present in garlic, and it is responsible for the particular aroma of the spice. The pharmacological attributes of allicin integrate a broad spectrum of properties (e.g., anti-inflammatory, immunomodulatory, antibiotic, antifungal, antiparasitic, antioxidant, nephroprotective, neuroprotective, cardioprotective, and anti-tumoral activities, among others). The primary goal of the present article is to review and clarify the common molecular mechanisms by which allicin and its derivates molecules may perform its therapeutic effects on cardiovascular diseases and neuroinflammatory processes. The intricate interface connecting the cardiovascular and nervous systems suggests that the impairment of one organ could contribute to the dysfunction of the other.
