In our recent study, we demonstrated that certain limonoids isolated from citrus seeds induced apoptosis in human pancreatic (Panc-28) cells. In this study, limonin, nomilin and limonexic acid (LNA) were investigated for understanding the possible mode of cytotoxicity in cultured pancreatic cancer (Panc-28) cells. All three limonoids inhibited Panc-28 cell proliferation, with IC50 values less than 50 μM after 72 h of incubation. The induction of apoptosis was confirmed through the cleavage of caspase-3, decreased mitochondrial membrane potential, and expression of apoptosis-related proteins. The Bax/Bcl2 expression ratio was increased up to 11-fold in cells pre-treated with 60 μM limonoids for 48 h. Apart from this, the limonoids also induced the expression of p21, and exhibited anti-inflammatory activity through decreasing the expression of cox-2, NF-κB and IL-6. Based on these results, we were interested in understanding the possible mode of inhibition by LNA, which exhibited the highest activity. The treatment of Panc-28 cells resulted in dose- and time-dependent induction of apoptosis-inducible proteins. In addition, treatment with 60 μM LNA resulted in the activation of Akt-associated signals to induce apoptosis, and the same was confirmed by the effects of the compounds on pAkt, p53, VEGF and caspase proteins. The results of this study demonstrated the cytotoxicity of limonoids to human pancreatic cancer cells through the modulation of genes involved in proliferation and survival.Sulfur mustard (SM) is recognized as one of the most lethal warfare agents. It has the potential to seriously affect public health and safety. To employ appropriate medical countermeasures and treat victims as quickly as possible, the development of a rapid and simple SM detection technique is crucial. The aim of the present study was to explore novel detection systems exhibiting excellent selectivity and high sensitivity. An SM probe, namely N-(rhodamine-B)-thiolactam-2-n-butane (SRB-NB), which was based on a thiolactam structure, was effectively designed and synthesized. The rhodamine and thiourea moieties played the roles of the chromogenic and reacting groups, respectively. Subsequently, using ionic liquids (ILs) as the solvents, a turn-on fluorescence detection system was constructed. Notably, it was found that imidazole-based ILs displayed good solubility for an SM simulant, specifically 2-chloroethyl ethyl sulfide (2-CEES). Moreover, 1-butyl-3-methylimidazolium dicyandiamide ([BMIm]DCA) IL held the maximum amount of 2-CEES (132.5 g/100 g). The SRB-NB probe exhibited better ultraviolet (UV) absorption and fluorescence properties in ILs than in other organic solvents. SRB-NB/IL was able to detect 2-CEES in liquid form with remarkable selectivity and sensitivity. The limit of detection (LOD) was established at 3.0 × 10-6 M. Importantly, SRB-NB/ILs also showed good optical response to gaseous 2-CEES and SM.A highly enantioselective synthesis of (R,S) or (S,S)-2,6-disubstituted dehydropiperidines has been previously achieved through Sn/Li transmetalation of the corresponding stannylated dehydropiperidines or of their precursors. Herein, we successively consider their Upjohn's syn dihydroxylation and their anti-dihydroxylation via an epoxidation reaction followed by epoxide opening reaction. The stereochemical course of these reactions was first reported including the use of appropriate protecting groups before considering the conversion of the obtained compounds into NH or NMe iminosugar hydrochlorides. A primary evaluation of the designed iminosugar C-glycosides as glycosidase inhibitors suggests candidates for the selective inhibition of α-galactosidase, amyloglycosidase and naringinase. Beyond the reported results, the method constitutes a highly modulable route for the synthesis of well stereodefined iminosugar C-glycosides, an advantage which might be used for the design of iminosugars to enhance their biological properties.We study the flexoelectric effect in fifty-four select atomic monolayers using ab initio Density Functional Theory (DFT). Specifically, considering representative materials from each of the Group III monochalcogenides, transition metal dichalcogenides (TMDs), Groups IV, III-V, and V monolayers, Group IV dichalcogenides, Group IV monochalcogenides, transition metal trichalcogenides (TMTs), and Group V chalcogenides, we perform symmetry-adapted DFT simulations to calculate transversal flexoelectric coefficients along the principal directions at practically relevant bending curvatures. Avasimibe concentration We find that the materials demonstrate linear behavior and have similar coefficients along both principal directions, with values for TMTs being up to a factor of five larger than those of graphene. In addition, we find electronic origins for the flexoelectric effect, which increases with monolayer thickness, elastic modulus along the bending direction, and sum of polarizability of constituent atoms.A novel and rapid approach to characterise the occurrence of contaminants of emerging concern (CECs) in river water is presented using multi-residue targeted analysis and machine learning-assisted in silico suspect screening of passive sampler extracts. Passive samplers (Chemcatcher®) configured with hydrophilic-lipophilic balanced (HLB) sorbents were deployed in the Central London region of the tidal River Thames (UK) catchment in winter and summer campaigns in 2018 and 2019. Extracts were analysed by; (a) a rapid 5.5 min direct injection targeted liquid chromatography-tandem mass spectrometry (LC-MS/MS) method for 164 CECs and (b) a full-scan LC coupled to quadrupole time of flight mass spectrometry (QTOF-MS) method using data-independent acquisition over 15 min. From targeted analysis of grab water samples, a total of 33 pharmaceuticals, illicit drugs, drug metabolites, personal care products and pesticides (including several EU Watch-List chemicals) were identified, and mean concentrations determined at 40 ± 37 ng L-1. For targeted analysis of passive sampler extracts, 65 unique compounds were detected with differences observed between summer and winter campaigns. For suspect screening, 59 additional compounds were shortlisted based on mass spectral database matching, followed by machine learning-assisted retention time prediction. Many of these included additional pharmaceuticals and pesticides, but also new metabolites and industrial chemicals. The novelty in this approach lies in the convenience of using passive samplers together with machine learning-assisted chemical analysis methods for rapid, time-integrated catchment monitoring of CECs.
