Protocatechualdehyde (Catechaldehyde), a natural polyphenol compound isolated from the roots of radix Salviae Miltiorrhizae, is associated with a wide variety of biological activities and has been widely used in medicine as an antioxidant, anti-aging, an antibacterial and anti-inflammatory agent[1].
Protocatechualdehyde (PCA) (50, 100 μM, 24/48 hours ) treated MCF-7 cells significantly decrease cell growth by 11% and 20% in 24 hours and by 22% and 27% in 48 hours, respectively[2]. Protocatechualdehyde (50, 100 μM, 24 hours) treated MCF-7 cells are increased by 1.9-fold and 2.6-fold in the concentrations of 50 μM and 100 μM, respectively. PCA suppresses proliferation of estrogen receptor (ER)-positive (MCF-7) breast cancer cells, but not ER-negative (MDA-MB-231) breast cancer cells[2].Protocatechualdehyde (0, 100, 200 μM, 48 hours in HCT116 and SW480 cells) affects the enzyme activity of HDAC and observed that PCA treatment resulted in inhibition of HDAC activity in dose-dependent manner[3].

工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
