General description
氧化砷（III），也称为三氧化二砷，是一种可用作合成多种砷基化合物原料的两性氧化物。
Application
氧化砷（III）可用于：
- 在封闭体系中通过静态氟化法合成五氟化砷（AsF5）。
- 在醋酸锌、2-甲氧基乙醇和单乙醇胺中加入As2O3，通过溶胶-凝胶自旋涂覆法制备砷掺杂 ZnO 薄膜。

This study aimed to explore macrophage polarization in acute graft-versus-host disease after hematopoietic stem cell transplantation, and investigated if arsenic trioxide (ATO) could correct this imbalance. In the colon of GVHD mice, we found that the number of F4/80+iNOS+ cells

Accumulated evidence has revealed a tight link between arsenic trioxide (ATO)-induced apoptosis and mitotic arrest in cancer cells. AKT, a serine/threonine kinase frequently over-activated in diverse tumors, plays critical roles in stimulating cell cycle progression, abrogating cell cycle checkpoints, suppressing

Arsenic trioxide (As2O3; ATO) is clinically effective in treating acute promyelocytic leukemia (APL); however, it frequently causes cardiotoxic effects. This study was designed to investigate whether ATO could induce apoptosis of cardiac fibroblasts (CFs) that play very important roles in

Alpha-fetoprotein (AFP)-producing gastric cancer (AFPGC), represented by the production of AFP, has a more aggressive behavior than common gastric cancer. The underlying mechanisms are not well understood. Arsenic trioxide (As(2)O(3)) is used clinically to treat acute promyelocytic leukemia(APL) and has
