Acid Water-ground Nano-realgar Is Superior to Crude Realgar in Promoting Apoptosis of MCF-7 Breast Cancer Cells

Current Medical Science, 2022
Realgar is a traditional mineral Chinese medicine with antitumor effects, but it has high toxicity and low efficacy in its crude form. The purpose of this study was to optimize realgar to increase its efficacy and therapeutic potential.Crude realgar (CR) was mechanically ground to obtain nano-realgar (NR), and then nano-realgar processed products ...

The Vaporization of Realgar, As4 S 4

Journal of The Electrochemical Society, 1983
The vaporization behavior of has been investigated by mass spectrometry and mass‐loss torsion‐effusion. The results of these studies indicate that the primary constituent of the vapor above crystalline is molecular , but that minor amounts of , , , , , and are also present. The enthalpy and entropy of vaporization at 450 K are and , respectively.

[Study on water processing conditions of Realgar].

Zhong yao cai = Zhongyaocai = Journal of Chinese medicinal materials, 2009
To optimize the water processing (shui-fei) condition of Realgar.The processing conditions were optimized by L9 (3)4 orthogonal design with three factors as water dose, process times and dryness temperature. The content of dissolved arsenic As(III) in Realgar was tested by High Performance Liquid Chromatography-hydride generation on-line coupled with ...

Zur Kenntnis des Realgar. II

Zeitschrift für anorganische und allgemeine Chemie, 1969
AbstractBei der Umsetzung von Realgar, As4S4, in N‐Methylaminoäthanol mit Piperidin oder Hexamethylenimin entstehen ein Piperidinium‐ bzw. Hexamethyleniminiumsalz mit dem Anion As4S. Durch doppelte Umsetzung mit Schwermetallsalzen gelingt es, Verbindungen der annähernden Zusammensetzung PbAs4S6 und HgAs4S6 zu erhalten. Das den neuen Thiosalzen zugrunde
