We prove the mirror duality conjecture for the mirror pairs constructed by Berglund, Hübsch, and Krawitz. Our main tool is a cohomological LG/CY correspondence which provides a degree-preserving isomorphism between the cohomology of finite quotients of Calabi–Yau hypersurfaces inside a weighte...
Fine-grained recognition is one of the most difficult topics in visual recognition, which aims at distinguishing confusing categories such as bird species within a genus. The information of part and bounding boxes in fine-grained images is very important for improving the performance. However, i...
Dipeptides and amides were obtained in high yields from N-carbobenzyloxy α-amino acids and 3-phenylpropanoic acid with unprotected α-amino acids via the corresponding mixed carbonic carboxylic anhydrides using ethyl chloroformate and triethylamine by an ecological and convenient method in whic...
A one-pot ambient-temperature procedure for the synthesis of 3,5-disubstituted-1,2,4-oxadiazoles from amidoximes and carboxylic acids under superbase-promoted conditions is reported.
In vitro and in vivo pharmacological properties of 5-{2-[4-(6-fluoro-1H-indole-3-yl)piperidin-1-yl]ethyl}-4-(4-fluorophenyl)thiazole-2-carboxylic acid amide (NRA0562), a novel atypical antipsychotic, were investigated. NRA0562 showed high affinities for human cloned dopamine D1, D2, D3 and D4 re...
The antipsychotic profile of 5-{2-[4-(6-fluoro-1H-indole-3-yl)piperidin-1-yl]ethyl}-4-(4-fluorophenyl)thiazole-2-carboxylic acid amide (NRA0562) was investigated using the conditioned avoidance test in rats. NRA0562 is a putative “atypical” antipsychotic agent with moderate to high affinities ...
Emodin (1,3,8-trihydroxy-6-methylanthraquinone) is an active constituent of Rheum palmatum, and showed inhibitory activity on lipopolysaccharide-induced NO production in our previous study. However, the apoptosis-inducing activity of emodin has remained undefined. Among three structurally relate...
Two stereocontrolled synthetic approaches to (E,E,E) and (Z,E,E)-α-chloro-ω-substituted hexatrienes 1–3 are described starting from unsaturated compounds 4–6. The key step of the first approach is based on the palladium-catalyzed rearrangement of bis-allylic acetates 4 and 5 and the second o...
3-Diethylamino-4-(4-methoxyphenyl)-isothiazole 1,1-dioxide (1) was made to react with arylalkyl- and arylazides 2. Cycloadducts 3, which could be isolated in some cases, afforded N-arylalkyl- or N-aryl-thiadiazabicyclo[3.1.0]hexene derivatives 4 through N2-elimination. Thermal rearrangements of ...
To develop a fluorometric method for assaying vitamin D metabolites and synthetic analogs, the reaction of major vitamin D3 metabolites and synthetic analogs with fluorescent dienophile (DMEQ-TAD) was studied, and the stereochemical structure of the resulting fluorescent adducts were determined ...
In this paper, a one-step copper-catalyzed procedure for oxidative coupling of active methylene compounds including cyclic β-diketones, cyclic β-ketoesters and 5-pyrazolone with benzenethiols is described. Benzenethiols are in situ generated in the reaction mixture from aryl halides and thiour...
We have studied the nonlinear optical properties for synthesized materials by using the Z-scan technique, in order to measure nonlinear refractive indices. The nonlinear optical properties of synthesized N-(2-hydroxyphenyl)-2-propylpentanamide (HO-AAVPA), in micellar aqueous solution of F127, we...
A water-soluble, small molecular zinc fluorescence probe (ZFP) based on 2-(2′-hydroxyphenyl) benzoxazole was prepared. It exhibited high selectivity and sensitivity to Zn2+ than the other metal ions. The highest fluorescence enhancement was observed in the presence of Zn2+ owing to the inhibiti...
Two fluorescein-labeled pyridinylimidazoles were synthesized and evaluated as probes for the binding affinity determination of potential kinase inhibitors to the c-Jun N-terminal kinase 3 (JNK3) and p38α mitogen-activated protein kinase (MAPK). Fluorescence polarization (FP)-based competition b...
A new series of 5-[(3′-chloro-4′,4′-disubstituted-2-oxoazetidinyl)(N-nitro)amino]-6-hydroxy-3-alkyl/aryl[1,3]azaphospholo[1,5-a]pyridin-1-yl-phosphorus dichlorides has been synthesized and subjected to acute antibacterial and antifungal screening studies. All the derivatives belonging to this...
Reaction of the potassium salts of N-thiophosphorylated thioureas of common formula RNHC(S)NHP(S)(OiPr)2 [R = pyridin-2-yl (HLa), pyridin-3-yl (HLb), 6-amino-pyridin-2-yl (HLc)] with Cu(PPh3)3I in aqueous EtOH/CH2Cl2 leads to mononuclear [Cu(PPh3)2La,b–S,S′] (1, 2) and [Cu(PPh3)Lc–S,S′] (3) ...
Mess in the physical world has lots of advantages—it platforms personal expression, enables personalized and effective organization and search, can spark creative interaction and exploration, and so on. In this Opportunity chapter, we illustrate how relaxing your over-tidy, clinical designs can...
By synthetically combining the utilization of different fuels and the co-production of alternative fuels and power, a multifunctional energy system (MES) can present more opportunities to achieve higher efficiency, lower investment, and less environmental impact as compared to traditional energy...
Seed harvesting ants are ecosystem engineers that shape vegetation, nutrient cycles, and microclimate. Progress in ecological research is, however, slowed down by poor species delimitation. For example, it has not been resolved to date, how many species the European harvester ant Messor “struct...
Few studies have inquired about the relationship between myrmecological activity and the granulometry and mineralogy of sediments of a palaeontological site. The objectives of this article are to determine the sedimentological or mineralogical distinctions produced by ants of the species Messor ...
