Introduction: Previous studies have reported that maternal asthma increases the risk of preterm birth. We hypothesized that inflammatory reactions caused by allergic diseases might affect the uterine environment and, subsequently, perinatal outcomes. The objective of this study was to examine the associations between allergic features among mothers and preterm pregnancy outcomes in a nationwide birth cohort. Methods: We analyzed data from pregnant women obtained from the Japanese Environment and Children’s Study (JECS), a nationwide general birth cohort study. We used binomial and multinomial logistic regression models to examine the associations between maternal allergic features and preterm birth, threatened preterm labor (TPL), and preterm premature rupture of the membrane (PPROM). Results: A total of 97,683 pregnant women were included. Prevalence of preterm birth, TPL, and PPROM was 4.7, 19.6, and 1.2%, respectively. Maternal history of allergic diseases (asthma, allergic rhinitis, allergic conjunctivitis, food allergy, drug allergy, and contact dermatitis) increased the risk of TPL(adjusted odds ratio [aOR] = 1.11 [95% CI: 1.06-1.17], aOR = 1.12 [1.08-1.16], aOR = 1.10 [1.04-1.16], aOR = 1.17 [1.09-1.26], aOR = 1.35 [1.23-1.48], and aOR = 1.34 [1.20-1.49], respectively). Although some maternal allergic features showed a negative association with preterm birth, the variables affecting preterm birth differed according to the gestational age of the fetus (22-33 weeks vs. 34-36 weeks). There were no significant associations between maternal allergic features and PPROM. Conclusion: Maternal allergic disease, except atopic dermatitis, may increase the risk of TPL. Comorbidity of maternal allergic disorders and perinatal adverse outcomes require further investigation.

The complex pathogenesis of Alzheimer’s disease (AD) has become a major obstacle in its therapy. One hopeful approach is to develop multifuntional ligands. Here, a total of 23 compounds based on nobiletin structure were designed and synthesized. The neuroprotective activities were evaluated for their antioxidant, anti-inflammatory and anti-A beta(42) (Amyloid beta-protein 42) neurotoxicity properties by MTT assays. The results demonstrated compound A12 was the most promising derivative against inflammatory (14.6 +/- 0.6 %) and cell damages induced by hydrogen peroxide (47.2 +/- 1.1 %), oxygen glucose deprivation (36.2 +/- 1.1 %) and A beta(42) (40.7 +/- 2.1 %). Molecular docking study revealed A12 formed a greater area of interactions with A beta(42) to prevent it from acquiring a beta sheet conformation for aggregation. Structure-activity relationships revealed the introduction of hydroxyl on ring B and aurone skeleton with a five-membered ring C could be benefit to increase their neuroprotective activities. In summary, A12 might represent a promising multifunctional neuroprotective agent against AD.

A heterogeneous organic-inorganic hybrid durable nanocatalyst gamma-Al2O3@Silane-TMG was prepared by covalently functionalization of nano-gamma-Al2O3 through anchored 3-chloropropyl- trimethoxysilane with 1,1,3,3-tetramethylguanidine (TMG). The structure of the catalyst was characterized by various techniques including FT-IR, XRD, SEM, EDX and TGA analyses. The synthesized nanocatalyst was successfully used in an efficient and green four-component synthesis of pyrazolopyranopyrimidine derivatives using ethyl acetoacetate, hydrazine hydrate, arylaldehydes and barbituric acid (or thiobarbituric acid) in H2O at 40 oC. This practical method produced the desired products at reduced reaction times (10-25 min) and high to excellent yields (85-98%). The main advantages of this practical method are the use of heterogeneous basic nanocatalyst, simple work-up procedure with no need to chromatographic purification, affording highly selective conversion and recyclability of the catalyst which could be used in 5 cycles with only a small decrease in its activity.

A series of 30 non-covalent imidazo[1,2-a]quinoxaline-based inhibitors of epidermal growth factor receptor (EGFR) were designed and synthesized. EGFR inhibitory assessment (against wild type) data of compounds revealed 6b, 7h, 7j, 9a and 9c as potent EGFR(WT) inhibitors with IC50 values of 211.22, 222.21, 193.18, 223.32 and 221.53 nM, respectively, which were comparable to erlotinib (221.03 nM), a positive control. Furthermore, compounds exhibited excellent antiproliferative activity when tested against cancer cell lines harboring EGFR(WT); A549, a non-small cell lung cancer (NSCLC), HCT-116 (colon), MDA-MB-231 (breast) and gefitinib-resistant NSCLC cell line H1975 harboring EGFR(L858R/T790M). In particular, compound 6b demonstrated significant inhibitory potential against gefitinib-resistant H1975 cells (IC50 = 3.65 mu M) as compared to gefitinib (IC50 > 20 mu M). Moreover, molecular docking disclosed the binding mode of the 6b to the domain of EGFR (wild type and mutant type), indicating the basis of inhibition. Furthermore, its effects on redox modulation, mitochondrial membrane potential, cell cycle analysis and cell death mode in A549 lung cancer cells were also reported.

Here-in, we present molecular design, chemical synthesis and evaluation of novel chromenyl-based 2-iminothiazolidin-4-one derivatives as tubulin polymerization inhibitors. The newly synthesized compounds were evaluated for their in vitro cytotoxicities against A549 (lung cancer), MDA-MB-231 and BT-471 (breast cancer), HepG2 (liver cancer) and HCT-116 (colon cancer) cell lines by MTT assay. Among the synthesized compounds, compound 12b showed excellent anticancer activity on MDA-MB-231 cell line with IC50 value of 0.95 +/- 1.88 mu M and was verified to be safe in normal human bronchial epithelial cells (Beas-2B). Apoptosis induced by the lead 12b was observed using morphological observations, AO/EB and DAPI staining procedures. Further, dose-dependent increase in the depolarization of mitochondrial membrane was also observed through JC-1 staining. Annexin V-FITC/PI assay confirmed that 12b induced early apoptosis. Additionally, cell cycle analysis indicated that the MDA-MB-231 cells were arrested at sub-G2/M phase and also inhibited tubulin polymerization with IC50 value of 3.54 +/- 0.2 mM. Molecular docking simulations were employed to identify the important binding modes responsible for the tubulin inhibitory activity, thus supporting their effective anticancer potential.

Apios americana Medik, a native American plant has potential as a commercially viable Northern European-grown motcrop, mainly due to its resistance to extreme climate and nutritional quality. Analysis of A. americana sourced from two UK sites; South (51.4690 degrees N, 1.1150 degrees W) and North (55.9661 degrees N, 3.2063 degrees W) showed that the tubers were a complete source of amino acids (UPLC-TUV analysis), were rich in protein (15.0 +/- 0.0160 and 17.3 +/- 0.0779%; Vario Max CN analysis), fibre (total non-starch polysaccharides, 10.4 +/- 0.570 and 10.6 +/- 0.280%; GC analysis) and micronutrients (calcium, manganese, iron, zinc, molybdenum, potassium and phosphorus; ICP-MS analysis). Apios americana tubers were also rich in bioactive phytochemicals. From the 156 plant metabolites measured using LC-MS/MS analysis, genistein was the major phytophenol in both the Southern- and Northern UK tubers (259 +/- 12.2 mg Kg(-1) and 356 +/- 29.9 mg Kg(-1) respectively); the peel having similar phytochemical profiles. The protein and fibre content of the leaves (17.3 +/- 0.0434% and 11.7 0.0445%) and rhizomes (18.4 +/- 0.0152% and 13.5 +/- 0.590%) were significantly higher (p < 0.05) than the tubers. The leaves were also a good source of anthocyanins; delphinidin and cyanidin (840 +/- 137 and 3934 +/- 176 mg Kg(-1) respectively). Cultivation of A. americana as a high-protein staple-crop has enormous potential in Northern European countries for human nutrition, diet diversification, and use in livestock diets.
