Accurate, reliable, and informative mapping of untargeted and targeted components across many samples is here performed by combining off-line GC-Olfactometry (GC-O) and comprehensive two-dimensional gas chromatography (GCxGC) coupled to time-of-flight mass spectrometry with variable ionization energy (TOF MS featuring Tandem Ionization (TM)). In particular, untargeted and targeted (UT) features patterns are processed by chromatographic fingerprinting, giving differential priority to potent odorants’ retention-times regions. Distinguishing peppermint essential oil (EO) from Piedmont (Italy – Mentha x piperita L. var. Italo-Mitcham – Menta di Pancalieri EO), with its unique sensory fingerprint (i.e., freshness and long-lasting sweetness), from high-quality peppermint EOs produced in other areas poses a great challenge. Chromatographic UT fingerprinting provided a great chemical dimensionality by mapping more than 350 peak-regions at 70 eV and 135 at 12 eV. From them, 95 components were identified and responses compared to available literature. Then, potent odorants, detected by GC-O using the aroma extraction dilution analysis (AEDA), were tracked over the chromatographic space and tentatively identified. With the highest flavor dilution (FD), 1,8-cineole (eucalyptus, fresh, camphoraceous); menthone (minty, herbaceous); and menthofuran (minty, musty, petroleum-like) were highlighted. Responsible for creamy and coumarinic notes were the diasteroisomers of (3,6)-dimethyl-4,5,6,7-tetrahydrobenzo[b]-furan-2(3H)-one (i.e., menthofurolactones), detected in higher relative abundance in Pancalieri EOs. By prioritizing the investigation of volatiles on higher LogFD retention regions, including 131 untargeted/targeted features, Pancalieri EOs were separately clustered from United States samples. Besides pre-targeted analytes, additional untargeted features were post-processed for identification within marker chemicals. Myrtenyl methyl ether, ethyl 3-methyl butanoate, propyl-2-methylbutanoate, and (E)-2-hexenal were putatively identified. Of the unknown – knowns with diagnostic roles, all metadata were collected including low energy spectra at 12 eV, which were found to be highly complementary to 70 eV spectra. (C) 2021 Elsevier B.V.

A series of new 17-cyanopyridine derivatives of pregnenolone have been synthesized, and their anti-proliferative activities against different human cancer cell lines were tested. The extensive structure-activity relationship (SAR) data suggested that the introduction of 2-amino-4-aryl-3-cyanopyridine to the D ring of pregnenolone may increase the anti-cancer activity. Among the products, the most potent compound 4j exhibited good growth inhibition against all the tested cells especially for PC- 3 cells with an IC50 value of 2.0 mu M. Further mechanistic studies showed that 4j inhibited the formation of cell colonies and migration, increased the level of reactive oxygen species (ROS) in PC-3 cells in a concentration-dependent manner, and induced necroptosis through the phosphorylation of receptor interacting protein 1/3 (P-RIP1/3) and phosphorylation of mixed lineage kinase domain-like protein (P-MLKL) pathway. The 17-pregnenolone cyanopyridine derivatives hold promising potential as anti-proliferative agents, and the most potent compound could be used as a starting point for the development of new steroidal heterocycles with improved anticancer potency and selectivity.

The B3NO2 six-membered heterocycle (1,3-dioxa-5-aza-2,4,6-triborinane = DATB), comprising three different non-carbon period 2 elements, has been recently demonstrated to be a powerful catalyst for dehydrative condensation of carboxylic acids and amines. The tedious synthesis of DATB, however, has significantly diminished its utility as a catalyst, and thus the inherent chemical properties of the ring system have remained virtually unexplored. Here, a general and facile synthetic strategy that harnesses a pyrimidine-containing scaffold for the reliable installation of boron atoms is disclosed, giving rise to a series of Pym-DATBs from inexpensive materials in a modular fashion. The identification of a soluble Pym-DATB derivative allowed for the investigation of the dynamic nature of the B3NO2 ring system, revealing differential ring-closing and -opening behaviors depending on the medium. Readily accessible Pym-DATBs proved their utility as efficient catalysts for dehydrative amidation with broad substrate scope and functional-group tolerance, offering a general and practical catalytic alternative to reagent-driven amidation.

The chemical class of benzotrifluoride derivatives is widely used in active ingredients of various commercial products, such as pharmaceuticals, pesticides, herbicides, and crop protection agents. Past studies have shown that some benzotrifluorides are not stable under UV irradiation in water and convert into benzoic acids due to C-F bond hydrolysis. It was also observed, but never systematically studied, that the ring substituents play an important role on the direct photochemical reactivity of the CF3 moiety. In the present work, we explore the structure-reactivity relationship between ring substituent and direct photodefluorination for 16 different substituents, by determining fluoride production rates, quantum yields, and half-lives, and found that strong electron-donating groups enhance the reactivity toward hydrolysis. In addition, flufenamic acid, travoprost, dutasteride, cyflumetofen, flutoanil, and teriflunomide were also examined, finding that their direct photochemical reactivity could be qualitatively predicted based on their ring substituents. We provide here a tool to evaluate the environmental persistence of benzotrifluoride contaminants, as well as to design more photodegradable new active ingredients.

A practical method for the synthesis of phenyl enol ethers is reported. The combination of a gold(I) catalyst and potassium carbonate selectively mediates the addition of phenols to propargylic alcohols/amines in a chemo-, regio-, and stereoselective fashion in high yield. The resulting enol ethers are formed exclusively with a Z-configuration and can be obtained from a wide array of phenols and propargylic alcohols or amines with the reaction showing excellent functional group tolerance.

Prenylated chalcones xanthohumol (1) and 2 ‘-hydroxy-3,4,4 ‘-trimethoxy-6 ‘-O-prenyl chalcone (2) were synthesized through the Claisen-Schmidt condensation, O-prenylation, and Claisen rearrangement and deprotection respectively, using phloroglucinol and appropriate benzaldehydes as starting materials. Based on the Mannich reaction of prenylated chalcone 1 or 2 with various secondary amines and formaldehyde in acid alcohol solvent, 10 novel prenylated chalcone Mannich base derivatives 3a-3e and 4a-4e were synthesized. Furthermore, all synthetic compounds were evaluated for antiproliferative activities in vitro against four human cancer cell lines (Aspc-1, SUN-5, HepG-2, and HCT-116) by MTT assay. The results showed that most of them exhibit moderate to good antiproliferative activities against the four human cancer cells with IC50 values of 2.52 to 47.67 mu M.

Characterization of volatile off-odor compounds in thermal duck egg gels was investigated by gas chromatography-olfactometry-mass spectrometry (GC-O-MS), odor activity values (OAVs) and aroma recombination. The results demonstrated that the off-odor of thermal duck egg mainly came from egg yolk (EY), and content of aldehydes was the highest in EY. Anaerobic treatment in nitrogen contributed to decreased off-odor sensory scores and volatile components of the heated egg gels. Aerobic EY gels (treated in air) were determined to contain eight volatile compounds with OAVs greater than 1, such as hexanal, nonanal, benzaldehyde, (E)-2-octenal, (E)-2-nonenal, (E, E)-2,4-decadienal, 1-octen-3-ol and 2-pentylfuran. However, three key volatile components (nonanal, benzaldehyde and (E)-2-nonenal) with OAVs greater than 1 were found in anaerobic EY gels. Moreover, on the basis of results of recombination and omission experiments, hexanal, (E)-2-octenal, (E, E)2,4-decadienal, 1-octen-3-ol and 2-pentylfuran were identified as key off-odor components in thermal EY gels. Sensory evaluation of the recombination model with five aroma compounds scored 4.38 out of 5 points. The major aroma profile of the off-flavor from egg EY gels included strong fatty, nutty, and mushroom aromas.

In an effort to develop novel Bax activators for breast cancer treatment, a series of diverse analogues have been designed and synthesized based on lead compound SMBA1 through several strategies, including introducing various alkylamino side chains to have a deeper access to S184 pocket, replacing carbon atoms with nitrogen, and reducing the nitro group of 9H-fluorene scaffold. Compounds 14 (CYD-2-11) and 49 (CYD-4-61) have been identified to exhibit significantly improved antiproliferative activity compared to SMBA1, with IC50 values of 3.22 mu M and 0.07 mu M against triple-negative breast cancer MDA-MB-231 and 3.81 mu M and 0.06 mu M against ER-positive breast cancer MCF-7 cell lines, respectively. Mechanism of action studies of compound 49 indicated that it can activate Bax protein to induce cytochrome c release and regulate apoptotic biomarkers, leading to cancer cell apoptosis. Further in vivo efficacy studies of compounds 14 and 49 in nude mice bearing MDA-MB-231 tumor xenografts demonstrated that these drug candidates can significantly suppress tumor growth, indicating their therapeutic potential for the treatment of breast cancer.

Benzyl alcohol (BnOH) is a natural colorless liquid organic compound that plays an important role in bacteriostatic and anesthetic processes. It is also used to relieve the nerve and ganglionic pain. In this study, we assessed the effect of topical application of BnOH on the Achilles tendon healing process. Sprague Dawley rats were subjected to an experimentally induced wound in the tendon area and then randomized into four groups. Normal saline (0.5 mL) was applied to rats in control group, and BnOH at the concentrations of 0.5 mL 0.075%, 0.15%, 0.3% were applied to the BnOH treatment groups, respectively. Wound treatment with BnOH led to significantly faster functional recovery than with saline. Moreover, treatment of wounds with 0.3% BnOH accelerated the healing process faster than with 0.075% and 0.15% BnOH. Histological analysis of healed wounds that had been treated with BnOH showed more collagen and blood capillaries and fewer inflammatory cells compared to the control. To study the mechanism of the process, the expression of mRNA of TGF-beta 1, Smad2/3 and Smad7 and protein of TGF-beta 1, p-Smad2/3 and Smad7 were quantified by real-time PCR and Western blotting, respectively. Results of this study showed that wounds treated with BnOH significantly enhanced the expression of TGF-beta 1 and Smad2/3 and reduced the expression of Smad7. In general, the current study demonstrated that BnOH improved the recovery process of tendon healing through the promotion of collagen with angiogenesis and showed that TGF-beta plays a role in BnOH treatment of tendon healing.

Under metal- and ligand-free conditions, the economical and accessible CF3SO3H successfully catalyzed homogeneous O-H bond insertion reactions between hydroxyl compounds and diazo compounds. Including phenols, alcohols, water and oximes, these O-H bond insertion reactions are very general and functional-group tolerant. Here, we first report the O-H bond insertion of oximes (ketoximes and aldoximes), and their structures were characterized by X-ray crystallography. Moreover, a simple and effective method for S-H insertion reactions of thiols was also developed, delivering the desired C-S bond products with good to excellent yields. It is worth noting that the efficacy of the developed methodology could be further shown by the expeditious synthesis of the PPAR agonist MBX-102 acid.
