Duan, Cancan published the artcilePharmacokinetics and tissue distribution of cantharidin after oral administration of aqueous extracts from Mylabris in rats, Formula: C12H15ClO3, the publication is Biomedical Chromatography (2021), 35(10), e5172, database is CAplus and MEDLINE.

A sensitive gas chromatog.-mass spectroscopy method was established for the determination of cantharidin (CTD) in rat plasma and liver homogenates. During the experiment, rats were randomly divided into two groups (low, high) and were administered aqueous extract of Mylabris compound for 7 days. Then, plasma and tissue samples were taken at different time points to study the pharmacokinetics and tissue distribution of CTD in rats. The selected reaction monitoring transitions for CTD and clofibrate (internal standard) were m/z 128 → 85 and m/z 169 → 141, resp. The calibration curve ranged from 10.26 to 3,078 ng/mL for plasma and from 10.26 to 246.24 ng/mL for liver homogenates. The lower limits of quantification were 10.26 ng/mL for both plasma and liver. The intra- and inter-day precision and accuracy were <20% for both plasma and liver homogenates. Extraction recovery ranged from 89.21 to 103.61% for CTD in rat plasma and liver and from 83.79 to 102.74% for IS in rat plasma and liver. Matrix effects ranged from 93.06 to 110.44% for CTD and from 91.65 to 110.80% for IS.

Hsu, Li-Na published the artcileCentral action of drugs for treatment of hypertension. I. Effect of reserpine on the conditioned response and blood pressure of normal dogs, Category: chlorides-buliding-blocks, the publication is Shengli Xuebao (1961), 24(3-4), 151-60, database is CAplus.

In 7 normal dogs given reserpine orally at 0.005-0.03 mg./kg. for 4-15 days, the positive conditioned response decreased and the reinforcement relation changed, sometimes with change in phase. The effect on the delayed conditioned response depends on dosage. A large dose (0.25 mg./kg.) seriously upset the equilibrium in stimulation-depression mechanisms to cause a nervous condition. With a daily dose of 0.005 or 0.01 mg./kg., no change in blood pressure was observed, but a change in conditioned response was quite distinct. This indicates that the cerebral cortex is more sensitive to resperine than the midbrain. It also indicates that the change in response is not induced by the action of resperine on the vasomotor center.

Chu, Haoke published the artcileAsymmetric Dearomatization of Indole by Palladium/PC-Phos-Catalyzed Dynamic Kinetic Transformation, Synthetic Route of 1451393-45-5, the publication is Angewandte Chemie, International Edition (2020), 59(49), 21991-21996, database is CAplus and MEDLINE.

A palladium-catalyzed intermol. dynamic kinetic asym. dearomatization of 3-arylindoles with internal alkynes was developed with the use of achiral Xantphos and chiral sulfinamide phosphine ligand (PC-Phos) as the co-ligands. This method could deliver various spiro[indene-1,3′-indole] compounds in good yields (up to 95% yield) with up to 98% ee. The salient features of the transformation include the use of readily available substrates, ease of scale-up and the versatile functionalization of the products. The mechanistic experiments gave some insights on active intermediates.

Reaction between phosphoryl substrates (EtO)₂P(O)R (R = H, Me, OEt) and Ti(NR₂)_nCl_4-n (R¹ = Me, Et, n = 2, 3, 4) and Mn(NEt₂)₂ leads to the exchange of one or both EtO groups for the NR₂ substituent. The reactivity of the system depends on electronic as well as steric effects of both substrates, and approx. correlates with Lewis acid-base interactions between the substrates.

Wan, Zhao-Kui published the artcileEfficacious 11β-Hydroxysteroid Dehydrogenase Type I Inhibitors in the Diet-Induced Obesity Mouse Model, Name: 2-Chloro-4-cyanobenzene-1-sulfonyl chloride, the publication is Journal of Medicinal Chemistry (2009), 52(17), 5449-5461, database is CAplus and MEDLINE.

Cortisol and the glucocorticoid receptor signaling pathway have been implicated in the development of diabetes and obesity. The reduction of cortisone to cortisol is catalyzed by 11β-hydroxysteroid dehydrogenase type I (11β-HSD1). 2,4-Disubsituted benzenesulfonamides were identified as potent inhibitors of both the human and mouse enzymes. The lead compounds displayed good pharmacokinetics and ex vivo inhibition of the target in mice. Cocrystal structures of compounds I and II bound to human 11β-HSD1 were obtained. Compound II was found to achieve high concentrations in target tissues, resulting in 95% inhibition in the ex vivo assay when dosed with a food mix (0.5 mg of drug per g of food) after 4 days. Compound II was efficacious in a mouse diet-induced obesity model and significantly reduced fed glucose and fasted insulin levels. Our findings suggest that 11β-HSD1 inhibition may be a valid target for the treatment of diabetes.

Wan, Tianfeng published the artcileCovalent organic nanospheres modified magnetic nanoparticles for extraction of blood lipid regulators in water samples, Name: Ethyl 2-(4-chlorophenoxy)-2-methylpropanoate, the publication is Journal of Separation Science (2021), 44(11), 2301-2309, database is CAplus and MEDLINE.

Covalent organic nanospheres are new kind of nanospherical polymer with large sp. surface area, uniform morphol., and excellent chem. and thermal stability. This material can be fabricated by a facile and rapid room temperature solution-phase strategy. In this work, magnetic nanoparticles were attached to the surface of covalent organic nanospheres, and the obtained composites were used for the extraction of blood lipid regulators such as clofibrate and fenofibrate. These composites were characterized with Fourier-transformed IR spectroscopy, XPS, and transmission electron microscopy. Several parameters that might affect the extraction efficiency including acetonitrile content, pH value, extraction time, and sample volume were investigated. Under optimum conditions, the proposed anal. method showed high extraction efficiency toward clofibrate and fenofibrate with enrichment factors between 60 and 83. This method exhibited outstanding anal. performance with wide linear range and excellent reproducibility and had low limits of detection in the range of 0.02-0.03 ng/mL. This method was also applied to the detection of clofibrate and fenofibrate in lake water samples, and good recoveries in the range of 92.6-112.6% was obtained.

Lin, Shuangjie published the artcileVisible-light-driven spirocyclization of epoxides via dual titanocene and photoredox catalysis, HPLC of Formula: 21286-54-4, the publication is Chemical Science (2020), 11(3), 839-844, database is CAplus and MEDLINE.

The synergistic utilization of titanocene/photoredox dual catalysis driven by visible light for the radical opening/spirocyclization of easily accessible epoxyalkynes. This environmentally benign process used organic donor-acceptor fluorophore 2,4,5,6-tetra(9H-carbazol-9-yl)isophthalonitrile as a photocatalyst and Hantzsch ester as an electron donor instead of stoichiometric metallic reductants. The photocatalytic conditions showed exceptionally high reactivity for the synthesis of privileged and synthetically challenging spirocycles, e.g., I, featuring a spiro all-carbon quaternary stereocenter. Cyclic voltammetry studies suggest that Cp₂TiIIICl is the catalytically active species.
