Lilium lancifolium and Lilium brownii viridulum were two common cultivars of Lilium in China, which have been used as a source of food in ancient China, and as a traditional herbal medicine in most northern hemispheres countries continues today. However, only a few secondary metabolites in Lilium closely related to human health have been reported. In this research, an offline two-dimensional (HILIC and RP C18) separation system combined with multimode high-resolution mass spectrometry data acquisition was established for in-depth exploration and comparison of the chem. components in Lilium. In total, 331 components were identified, among which phenylpropanoid derivatives and steroidal saponins were the most abundant components. Furthermore, sulfur derivatives and steroidal alkaloids were systematically characterized in Lilium for the first time. These results provided valuable information for in-depth differentiating types of components characterization, which may be applied to assess and improve the edible and medicinal values of Lilium.

The pK values and σ constants (Taft, Hammett, Webster, and Dewar constants) were determined for substituted indole-2-carboxylic acids (I). The transfer of the elec. charges in this ring system is weaker than in carbocyclic systems. The electron-donating groups have very little effect. The relation of structure with the pK of I is best expressed in terms of the Dewar theory.

Maity, Asim; Hyun, Sung-Min; Powers, David C. published the artcile< Oxidase catalysis via aerobically generated hypervalent iodine intermediates>, Reference of 112-63-0, the main research area is hypervalent iodine reagent preparation oxidase catalysis aryl iodide.

The development of sustainable oxidation chem. demands strategies to harness O2 as a terminal oxidant. Oxidase catalysis, in which O2 serves as a chem. oxidant without necessitating incorporation of oxygen into reaction products, would allow diverse substrate functionalization chem. to be coupled to O2 reduction Direct O2 utilization suffers from intrinsic challenges imposed by the triplet ground state of O2 and the disparate electron inventories of four-electron O2 reduction and two-electron substrate oxidation Here, we generate hypervalent iodine reagents-a broadly useful class of selective two-electron oxidants-from O2. This is achieved by intercepting reactive intermediates of aldehyde autoxidation to aerobically generate hypervalent iodine reagents for a broad array of substrate oxidation reactions. The use of aryl iodides as mediators of aerobic oxidation underpins an oxidase catalysis platform that couples substrate oxidation directly to O2 reduction We anticipate that aerobically generated hypervalent iodine reagents will expand the scope of aerobic oxidation chem. in chem. synthesis.

Sodium glucose co-transporter 1 (SGLT1) plays a dominant role in the absorption of glucose in the gut and is considered a promising target in the development of treatments for postprandial hyperglycemia. A series of 4-benzyl-1H-pyrazol-3-yl β-d-glucopyranoside derivatives have been synthesized, and its inhibitory activity toward SGLTs has been evaluated. By altering the substitution groups at the 5-position of the pyrazole ring, and every position of the Ph ring, we studied the structure-activity relationship (SAR) profiles and identified a series of potent and selective SGLT1 inhibitors. Representative derivatives showed a dose-dependent suppressing effect on the escalation of blood glucose levels in oral mixed carbohydrate tolerance tests (OCTT) in streptozotocin-nicotinamide-induced diabetic rats (NA-STZ rats).

Balannik, Victoria; Wang, Jun; Ohigashi, Yuki; Jing, Xianghong; Magavern, Emma; Lamb, Robert A.; De Grado, William F.; Pinto, Lawrence H. published the artcile< Design and Pharmacological Characterization of Inhibitors of Amantadine-Resistant Mutants of the M2 Ion Channel of Influenza A Virus>, Related Products of 112-63-0, the main research area is spiroundecane preparation influenza virus M2 channel blockade SAR.

The A/M2 proton channel of influenza A virus is a target for the anti-influenza drugs amantadine and rimantadine, whose effectiveness was diminished by the appearance of naturally occurring point mutants in the A/M2 channel pore, among which the most common are S31N, V27A, and L26F. We have synthesized and characterized the properties of a series of compounds, originally derived from the A/M2 inhibitor BL-1743. A lead compound emerging from these investigations, spiro[5.5]undecan-3-amine, is an effective inhibitor of wild-type A/M2 channels and L26F and V27A mutant ion channels in vitro and also inhibits replication of recombinant mutant viruses bearing these mutations in plaque reduction assays. Differences in the inhibition kinetics between BL-1743, known to bind inside the A/M2 channel pore, and amantadine were exploited to demonstrate competition between these compounds, consistent with the conclusion that amantadine binds inside the channel pore. Inhibition by all of these compounds was shown to be voltage-independent, suggesting that their charged groups are within the N-terminal half of the pore, prior to the selectivity filter that defines the region over which the transmembrane potential occurs. These findings not only help to define the location and mechanism of binding of M2 channel-blocking drugs but also demonstrate the feasibility of discovering new inhibitors that target this binding site in a number of amantadine-resistant mutants.

Li, Lin; Wang, Hui; Zhao, Shuping; Zhao, Yuan; Chen, Yongping; Zhang, Jiuyan; Wang, Chuqiao; Sun, Ning; Fan, Honggang published the artcile< Paeoniflorin ameliorates lipopolysaccharide-induced acute liver injury by inhibiting oxidative stress and inflammation via SIRT1 / FOXO1a / SOD2 signaling in rats>, HPLC of Formula: 112-63-0, the main research area is inflammation oxidative stress paeoniflorin ameliorates lipopolysaccharide acute liver injury; NLRP3 inflammasome; Paeoniflorin; SIRT1/FOXO1a/SOD2 signaling; acute liver injury; mitochondrial ROS.

Acute liver injury (ALI) is a poor prognosis and high mortality complication of sepsis. Paeoniflorin (PF) has remarkable anti-inflammatory effects in different disease models. Here, we explored the protective effect and underlying mol. mechanisms of PF against lipopolysaccharide (LPS)-induced ALI. Sprague-Dawley rats received i.p. (i.p.) injection of PF for 7 days, 1 h after the last administration, and rats were injected i.p. 10 mg/kg LPS. PF improved liver structure and function, reduced hepatic reactive oxygen species (ROS) and methane dicarboxylic aldehyde (MDA) levels, and increased superoxide dismutase (SOD) activity. Western blot anal. suggested that PF significantly inhibited expression of inflammatory cytokines (TNF-α, IL-1β, and IL-18) and inhibited activation of the NLRP3 inflammasome. PF or mitochondrial ROS scavenger (mito-TEMPO) significantly improved liver mitochondrial function by scavenging mitochondrial ROS (mROS), restoring mitochondrial membrane potential loss and increasing level of ATP and enzyme activity of complex I and III. In addition, PF increased expression of sirtuin-1 (SIRT1), forkhead box O1 (FOXO1a) and manganese superoxide dismutase (SOD2), and increased FOXO1a nuclear retention. However, the inhibitor of SIRT1 (EX527) abolished the protective effect of PF. Taken together, PF promotes mROS clearance to inhibit mitochondrial damage and activation of the NLRP3 inflammasome via SIRT1/FOXO1a/SOD2 signaling.
