Despite studies on umbelliferous fruits flavor makeup, nothing is known regarding roasting impact on their fruit aroma. Five major umbelliferous crops viz., anise, caraway, coriander, cumin and fennel were analyzed via headspace solid-phase microextraction to reveal for 117 volatile constituents. Oxygenated monoterpenes amounted for the major volatile class in raw fruits at 75% with (E)-anethole, carvone, beta-linalool, cuminaldehyde and estragole as major components in anise, caraway, coriander, cumin, and fennel, respectively. Difference was observed in fennel fruit ?estragole? levels derived from different origins. Upon roasting, several novel volatiles were detected viz. pyrazines and flavored Milliard type volatiles. Major flavor intensified response was detected in cumin with an increase in its ?cuminaldehyde? levels versus a decrease of estragole levels in fennel. Roasted cumin exhibited highest peroxide value 14.2 mEq O2/Kg, whereas the least was detected in fennel at 6.1 mEq O2/Kg, though with both values not representing a health hazard.

Novel achiral and chiral alkyl alpha-(1,3-benzothiazol-2-ylsulfonyl)- alpha-fluoroacetates can be readily synthesized by metalation-fluorination of (1,3-benzothiazol-2-ylsulfonyl)acetates. DBU-mediated condensations of these fluorinated synthons with aldehydes proceed in a facile manner at 0 C or at room temperature giving high yields of alpha-fluoro acrylates. Ketones are unreactive under these conditions. The presence of fluorine renders the synthon substantially more reactive compared to the unfluorinated analogue. Reactivity of alpha-(1,3-benzothiazol-2-ylsulfonyl)-alpha-fluoroacetate and the Horner-Wadsworth-Emmons reagent (EtO)2P(O)CHFCOOEt has also been compared.

Ethnopharmacological relevance: Plants of Epilobium angustifolium are popular in China to treatment of traumatic injury, subduing inflammation and menstrual disorders. In European, the preparations or extracts containing E. angustifolium are popular to treat prostate diseases. Recent research suggested that E. angustifolium showed therapeutic effects in early stage of BPH, inflammation of urethra and prostate, as well as micturition problems. And the related researches were focus on aqueous extract and its main constituent of oenothein B. Aim of the study: This study aims to evaluate the therapeutic effect against BPH of the ethyl acetate extracts (EAE) and n-butanol extracts (BUE) from E. angustifolium and to chemical investigation of the active constituents. Materials and methods: The in vitro anti-BPH activity was assessed by determining the benign prostatic hyperplasia epithelial-1 (BPH-1) cell viability using MTT assay as well as suppressing of prostate specific antigen (PSA) secretion in prostate epithelial cancer hormone-dependent (LNCaP) cells measured by ELISA method. The in vivo anti-BPH was evaluated by testosterone propionate induced BPH SD rats. After oral administration of BUE at 100, 200 and 400 mg/kg B.W. for 28 days, the prostate weight and index, plasma androgen level, histopathological alteration, oxidative and inflammatory-related factors in prostate were assessed. Phytochemical investigation on active extracts was carried by chromatographic and spectroscopic techniques. Anti-BPH activities of the isolates were evaluated in vitro. Results: BUE and EAE from E. angustifolium exhibited significant anti-BPH effect in vitro. Further in vivo study demonstrated that BUE exhibited therapeutic effects against TP-induced BPH in SD rats via down-regulating of the androgen level, suppressing the expression of NF-kappaB and eventually alleviating the inflammatory responses and oxidative stress. Phytochemical research on BUE and EAE extracts led to the isolation and identification of 50 compounds. In vitro anti-BPH screening revealed that 26 compounds exhibited anti-proliferation in BHP-1 cell and 36 compounds showed PSA inhibition in LNCap cell, in which 7 compounds exhibited very significant anti-BPH activities in both two cell lines (P < 0.01), 5 compounds with extremely significant activities in one of the cell lines (P < 0.001), and compound 25 exhibited the most potent anti-BPH activity (P < 0.001). Conclusions: E. angustifolium exhibited the therapeutic potential against BPH, and its active compounds may be used as candidate for treatment of BPH.

Electric Literature of 652-39-1, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 652-39-1, 4-Fluoroisobenzofuran-1,3-dione, introducing its new discovery.

Methods to incorporate deuterium and tritium atoms into organic molecules are valuable for medicinal chemistry. The prevalence of pyridines and diazines in pharmaceuticals means that new ways to label these heterocycles will present opportunities in drug design and facilitate absorption, distribution, metabolism, and excretion (ADME) studies. A broadly applicable protocol is presented wherein pyridines, diazines, and pharmaceuticals are converted into heterocyclic phosphonium salts and then isotopically labeled. The isotopes are incorporated in high yields and, in general, with exclusive regioselectivity.

Reference of 1552-42-7, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 1552-42-7, Crystal violet lactone, introducing its new discovery.

The aim of this work is to investigate the luminescence color changes of thermosensitive luminous fibers (TLFs). These TLFs are comprised of rare-earth luminescent materials as the luminescence sources, reversible thermochromic crystal violet lactone (CVL) pigment as the luminescence conversion agent, and polyacrylonitrile (PAN) as the matrix. It was found that the TFLs could not only change their color, but also convert the luminescence upon temperature change based on a structural transformation of the CVL pigment. X-ray diffraction (XRD) measurements indicated that rare-earth luminescent materials maintained their basic crystal structure and the CVL pigment was not destroyed by the process of spinning. The scanning electron microscopy (SEM) images of TLFs at the microcosmic angle showed that the CVL pigments were evenly distributed in the PAN matrix and formed a luminescence filter on the surface of the fiber. The differential scanning calorimetry (DSC) and thermogravimetry (TGA and DTG) results indicate that the TLFs possess satisfactory thermostability below 212.6 C. The color and luminescence of the TLFs were accurately exhibited on the CIE 1931 chromaticity coordinates. The thermosensitive capability of TLFs was qualitatively verified by observing them in water at 40 C and it was found that the fibers had brilliant luminescence and vivid thermosensitivity.
