In vitro testing: In vitro testing was performed using DIMSCAN, a semiautomatic fluorescencebased digital image microscopy system that quantifies viable (using fluorescein diacetate [FDA]) cell numbers in tissue culture multiwell plates [1]. Cells were incubated in the presence of drug for 96 hours. Mean fluorescence values were determined for each concentration tested and then normalized to th...

The identification of a suitable non-fluorescent molecule that can be oxidized by G-quadruplexes into a fluorescent product will be important for several fields such as bioanalyte sensing and cancer therapeutic discovery. Herein, we demonstrate that 2',7'-dichlorodihydrofluorescein diacetate is a superior reducing substrate for the fluorometric detection of bioanalytes using peroxidase-mimickin...

A photostable dicyanomethylenedihydrofuran fluorophore which contains electron-donating alkoxy groups is described. This chromophore is highly environmentally-sensitive, which is a remarkable property for a fluorescent reporter. Its light excitation also enables, in low viscous solvents, the formation of dark states whose radical or triplet nature is ruled out.

The title compound, C(19)H(24)O(6), is a sesquiterpene lactone isolated from the Kenyan plant Warburgia ugandensis. Ring A adopts a chair conformation, ring B is in a C(2) twist conformation and the lactone ring is nearly planar with maximum deviation 0.007 (1) Å. The reported absolute configuration is based on that of the similar compound bromo-parasiticolide A and is supported by analysis of ...

• In an independent noninferiority FTAI study of 2,620 cows from 40 Canadian herds, first service CR was 40.4% for FACTREL and 41.0% for Fertiline® (GnRH acetate, Vétoquinol, Lavaltrie, Quebec, Canada); FACTREL was noninferior to Fertiline.3 Another independent study with 3,938 cows showed CR of FACTREL was noninferior to Cystorelin® (gonadorelin diacetate tetrahydrate injection) in FTAI (36% v...

In the title compound, [Cu(C(4)H(5)O(4))(H(2)O)](n), the imino-diacetate (ida) ligands link the Cu(II) atoms into polymeric zigzag chains running along [010]. Each Cu(II) ion is five-coordinated in a distorted square-pyramidal geometry by one N and two O atoms from an ida ligand, one O atom from the neighbouring ida ligand and one water O atom. In the crystal, the polymeric chains are held toge...

A new tetracyclic biscembrane hydrocarbon, trocheliane (1), along with two new cembranoid diterpenes, sarcotrocheldiol A (2) and B (3), and the known diterpene cembrene-C (4), were isolated from the Red Sea soft coral Sarcophyton trocheliophorum. The structures and relative stereochemistry of the compounds were elucidated by interpretation of MS, 1 D NMR, and 2 D NMR experiments. The sensitivit...
