Xu, Shengtao published the artcileA Novel Potent Anticancer Compound Optimized from a Natural Oridonin Scaffold Induces Apoptosis and Cell Cycle Arrest through the Mitochondrial Pathway, Application In Synthesis of 6313-54-8, the publication is Journal of Medicinal Chemistry (2017), 60(4), 1449-1468, database is CAplus and MEDLINE.

The cytotoxicity of the natural ent-kaurene diterpenoid, oridonin, has been extensively studied. However, the application of oridonin for cancer therapy was hampered primarily by its moderate potency. In this study, a series of oridonin A-ring modified analogs, and their derivatives bearing various substituents on 14-OH position, were designed, synthesized and evaluated for anticancer efficacy. Some of the derivatives were significantly more potent than oridonin against both drug-sensitive and drug-resistant cancer cells. The most potent compound, I, was 200-fold more efficacious than oridonin in MCF-7 cancer cells. Furthermore, I induced apoptosis and cell cycle arrest at the G2/M phase. A decrease in mitochondrial membrane potential and increased Bax/Bcl-2 ratio, accompanied by activated caspase-3 cleavage, were observed in MCF-7 cells after treatment with I, suggesting that the mitochondrial pathway was involved in the I-mediated apoptosis. Moreover, I significantly inhibited tumor growth in mouse xenograft models and had no observable toxic effect.

Tian, Jun-Jie published the artcileBorane-Catalyzed Chemoselective and Enantioselective Reduction of 2-Vinyl-Substituted Pyridines, Safety of N-Benzyl-N,N-dibutylbutan-1-aminium chloride, the publication is Angewandte Chemie, International Edition (2020), 59(42), 18452-18456, database is CAplus and MEDLINE.

Herein, we report that highly chemoselective and enantioselective reduction of 2-vinyl-substituted pyridines has been achieved for the first time. The reaction, which uses chiral spiro-bicyclic bisboranes as catalysts and HBpin and an acidic amide as reducing reagents, proceeds through a cascade process involving 1,4-hydroboration followed by transfer hydrogenation of a dihydropyridine intermediate. The retained double bond in the reduction products permits their conversion to natural products and other useful heterocyclic compounds by simple transformations.

Li, Long-Di published the artcileRoom temperature phosphorescence properties of 27 coumarin derivatives on filter paper, Quality Control of 10543-42-7, the publication is Analytica Chimica Acta (1994), 296(1), 99-105, database is CAplus.

Some coumarin derivatives were used as fluorescence labeling agent. The room temperature phosphorescence (RTP) properties of 27 kinds of coumarin derivatives on filter paper were studied. Most of them can give more intensive RTP signals when using 1.0 mol L^-1 lead acetate as a heavy-atom perturber and there is an obvious relation between the RTP characteristics and the substituting group in some of the derivatives The fact that many of the coumarin derivatives can give RTP emission means that they can be expected to serve as RTP labeling agent.

Li, Longdi published the artcileRoom temperature phosphorescence properties of 6-coumarinsulfonyl chloride, HPLC of Formula: 10543-42-7, the publication is Fenxi Huaxue (1992), 20(11), 1257-60, database is CAplus.

6-Coumarinsulfonyl chloride (C₆SCl) was used as the fluorescence and low-temperature phosphorescence labeling reagent for amino acids. In this paper, the room-temperature phosphorescence (RPT) of C₆SCl on the several solid substrates, such as filter paper, polyamide films, microcrystalline cellulose, cellulose nitrate, and silica gel for chromatog. etc. was induced successfully by selection of the heavy atom perturbers and exptl. conditions. The RTP emission of C₆SCl has high selectivity, only divalent lead salts are efficient perturber among the examined fifteen compounds and the Pb(OAc)₂ induced the most strong RTP signal. Using 1.0 mol/L Pb(OAc)₂ as the perturber and filter paper as the solid substrate, more intensive RTP signal with high signal to blank ratio was obtained. The RTP signal intensity (λ_x/λ_m = 320/496 nm) as a function of the amount of C₆SCl has a good linear relationship in 0.2 μL sample solution containing 4 to 200 pmol. These results mean that C₆SCl, a new developing luminescence-labeling compound, can be expected to serve as not only a fluorescence labeling reagent, but also a RTP one.
