McCourt, RO; Scanlan, EM in [McCourt, Ruairi O.; Scanlan, Eoin M.] Univ Dublin, Trinity Coll Dublin, TBSI, Dublin 2, Ireland published A Sequential Acyl Thiol-Ene and Thiolactonization Approach for the Synthesis of delta-Thiolactones in 2019.0, Cited 38.0. Formula: C8H18O3. The Name is 1,1,1-Triethoxyethane. Through research, I have a further understanding and discovery of 78-39-7.

A novel strategy for the synthesis of delta-thiolactones from inexpensive and readily available gamma-unsaturated esters has been developed. This strategy incorporates a radical acyl thiol-ene reaction as the key C-S bond forming step. Cyclization is achieved via a Steglich-type thiolactonization of 5-mercaptopentanoic acids. We report the facile and scalable synthesis of delta-thiolactones in moderate to good yield under mild reaction conditions with tolerance for a range of functional groups.

The resistance of tumors against anticancer drugs is a major impediment for chemotherapy. Tumors often develop multidrug resistance as a result of the cellular efflux of chemotherapeutic agents by ABC transporters such as P-glycoprotein (ABCB1/P-gp), Multidrug Resistance Protein 1 (ABCC1/MRP1), or Breast Cancer Resistance Protein (ABCG2/BCRP). By screening a chemolibrary comprising 140 compounds, we identified a set of naturally occurring aurones inducing higher cytotoxicity against P-gp-overexpressing multidrug-resistant (MDR) cells versus sensitive (parental, non-P-gp-overexpressing) cells. Follow-up studies conducted with the P-gp inhibitor tariquidar indicated that the MDR-selective toxicity of azaaurones is not mediated by P-gp. Azaaurone analogs possessing pronounced effects were then designed and synthesized. The knowledge gained from structure-activity relationships will pave the way for the design of a new class of anticancer drugs selectively targeting multidrug-resistant cancer cells.

A method is developed for in situ generation of 1,3-dioxan-5-one derivatives 2. These compounds are simple precursors for accessing carbohydrate structures and previously had to be produced via stepwise procedures using excessive amounts of reagents. In the present work, three different derivatives of 2 were synthesized via the reaction of trialkoxyalkanes with dihydroxyacetone dimer 1 in the presence of acetic acid as the catalyst. In the same pot, derivatives of 2 were reacted with aromatic aldehydes and 30 mol% of pyrrolidine to obtain high yields of the respective bischalcones 3 within short time periods.

A concise and straightforward total synthetic approach towards lycorine-type alkaloid (-)-gamma-lycorane has been achieved in 7 steps. The key feature of the route is the employment of a palladium-catalyzed aromatic C-H alkylation of unactivated secondary alkyl iodide. The synthetic protocols also involve a palladium-catalyzed deracemization of allylic carbonate, a Johnson-Claisen rearrangement and an iodocyclization. (C) 2020 Elsevier Ltd. All rights reserved.

HPLC of Formula: C15H12O. Keskin, S in [Keskin, Saban] Bilecik Seyh Edebali Univ, Vocat Sch Hlth Serv, Bilecik, Turkey published Orange peel volatile oil: A green solvent for propolis extraction, enhanced alpha-amylase inhibition activity in 2020, Cited 24. The Name is Chalcone. Through research, I have a further understanding and discovery of 94-41-7.

Orange peel oil contains high amount of d-limonene which is reported to have antidiabetic activity. Propolis contains many biologically active compounds like phenolic acids, flavonoids and terpenes. Because of its rich phenolic composition, antidiabetic activity of propolis has also been shown in literature. Consumption of raw propolis is limited because of its resinous nature. It should be extracted to convert it into consumable form. Ethanol is the most used solvent for this purpose. Ethanol is the limiting factor for propolis consumption either for religious concerns or being harmful for human health. There is an increasing need for new, compatible and healthier solvents for propolis extraction. This is the first paper describing the extraction of propolis with orange peel oil. 1:10 (g/v) ratio was used for extraction. Orange peel oil (OPO), orange peel oil propolis extract (OPOPE) and ethanol propolis extract (EPE) were separately analysed by using GC-MS technique. Total phenolic content of oil and propolis extract was also carried out. Inhibition of alpha-amylase from barley malt with new extract was also reported. It was found that OPOPE was rich in volatile compounds of propolis, phenolic acid derivatives and free fatty acids. It was observed that OPOPE showed higher inhibition on alpha-amylase enzyme (IC50 0.196 mg/mL). It can be concluded that orange peel oil could be used as solvent for preparing propolis extract. Propolis extract obtained with orange peel oil could also be used as complementary medicine for the treatment of type 2 diabetes.

Yu, DD; Liang, XR in [Yu, Dandan; Liang, Xianrui] Zhejiang Univ Technol, Coll Pharmaceut Sci, Minist Educ, Key Lab Green Pharmaceut Technol & Related Equipm, Hangzhou 310014, Zhejiang, Peoples R China published Characterization and Identification of Isoflavonoids in the Roots of Millettia speciosa Champ. by UPLC-Q-TOF-MS/MS in 2019.0, Cited 30.0. Quality Control of Chalcone. The Name is Chalcone. Through research, I have a further understanding and discovery of 94-41-7.

Introduction: The root of Millettia speciosa Champ. (Leguminosae) is one of the well-known traditional Chinese medicines abundant in phenolic compounds and plays important roles in the treatment of pain or numbness of the joints, blood deficiency sallow, chronic bronchitis and chronic hepatitis. Objective: An ultra-high performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS/MS) based chemical profiling approach was established for the separation and characterization of isoflavonoids in the roots of Millettia speciosa Champ. Methods: The roots of Millettia speciosa Champ. were prepared by ethanol extraction followed by further extraction with chloroform. The extracts were analyzed by UPLC-Q-TOF-MS in positive and negative electrospray ion modes at different Collision Energy (CE) values. Results: A total of 48 components were simultaneously detected, of which 38 components, including 21 isoflavones, 4 phenolic acids, 4 isoflavanones, 2 phenolic aldehydes, 2 flavanones, 1 aliphatic acid, 1 chalcone, 1 flavonol, 1 isoflavane and 1 pterocarpan were unambiguously identified or tentatively assigned based on the retention time, UV spectra, characteristic molecular ions, MS/MS fragmentation data and reference standards. The isomers of isoflavonoids were distinguished using accurate mass, the diagnostic fragmentations of C-ring and UV spectra. The major diagnostic fragment ions of isoflavonoids were observed and the corresponding fragmentation pathways were proposed. Conclusion: This investigation provides important analysis data for further quality control, pharmacological and toxicological research on Millettia speciosa Champ.
