In the title compound, [Ru(CH3OCS2)2(C18H15P)2], the Ru(II) atom is in a distorted octa-hedral coordination by two xanthate anions (CH3OCS2) and two tri-phenyl-phosphane (PPh3) ligands. Both bidentate xanthate ligands coordinate the Ru(II) atom with two slightly different Ru-S bond lengths but with virtually equal bite angles [71.57 (4) and 71.58 (3)°]. The packing of the complexes is assured b...

The presence of left ventricular outflow tract obstruction (LVOTO) of either a resting or dynamic nature may have important therapeutic and prognostic implications in patients with hypertrophic cardiomyopathy (HCM). Doppler echocardiograms combined with amyl nitrite (Amyl) inhalation were performed in 333 consecutive patients referred for suspected HCM to diagnose and categorize the nature and ...

Several recent publications have shown that changes in heart murmurs after the inhalation of amyl nitrite may be of diagnostic aid (Vogelpoel et al., 1959; Barlow and Shillingford, 1958). The effect of amyl nitrite on intracardiac heemodynamics and intracardiac heart sounds has been studied extensively by Vogelpoel et al. (1960, 1961) and Schrire et al. (1961). For the past four years amyl nitr...

In the title compound, C15H17NO4S2, synthesized by addition of O-ethylxanthic acid potassium salt to a diastereomeric mixture of (4R)-3-(2-chloro-propano-yl)-4-phenyl-oxazolidin-2-one, the oxazolidinone ring has a twist conformation on the C-C bond. The phenyl ring is inclined to the mean plane of the oxazolidinone ring by 76.4 (3)°. In the chain the methine H atom is involved in a C-H⋯S and a ...

i had angina with normal coronary arteries. This group was compared with i5 patients who had angiographically proven coronary artery disease and positive treadmill tests but negative amyl nitrite tests: the group with positive amyl nitrite tests responded to drug inhalation with a significantly greater heart rate increase (47% vs. 34%, P< o.oI), and a significantly greater fall in systolic bloo...

A series of triorganophosphinegold(1) dithiocarbamate (R(3)PAuS(2)CNR'(2)) and xanthate (R(3)PAuS(2)COR') complexes have been prepared and characterised spectroscopically. Based on crystallographic evidence, the molecules feature linear gold(1) geometries defined by sulphur and phosphorus donors. The complexes, along with a series of known anti-cancer agents, have been screened against a panel ...

Tricyclodecan-9-yl-xanthogenate (D609) has been extensively studied in biological systems and exhibits a variety of biological functions, including antiviral, antitumor, and anti-inflammatory activities. Most of these activities have been largely attributed to the inhibitory effect of D609 on phosphatidylcholine-specific phospholipase C. However, as a xanthate derivative, D609 is a strong elect...

In this paper, the effect of ultrasonic pre-treatment and aeration on the flotation separation of chalcopyrite from pyrite was investigated at different amounts of potassium ethyl xanthate (KEX), as a collector, and pH values. Artificially-mixed samples of chalcopyrite and pyrite were subjected to flotation studies to understand the effect of aeration with or without ultrasonic tre...
