(rac) salvianic acid a

(Rac)-Salvianic acid A is the racemic form of Salvianic acid A, an orally active phenolic compound. (Rac)-Salvianic acid A activates the Nrf2/HO-1 signaling pathway while inhibiting the NF-κB pathway, exhibiting potential for antioxidant, anti-apoptotic, and anti-pulmonary inflammatory effects. (Rac)-Salvianic acid A is suitable for research in COVID-19, cardiovascular, and cerebrovascular diseases.

Danshensu (Dan shen suan A) is an active ingredient of *Salvia miltiorrhiza* with extensive cardiovascular benefits.

Danshensu sodium salt (Sodium Danshensu) is sodium salt of danshensu from the widely used Chinese herb Danshen. It can inhibited phenylephrine- and CaCl2-induced vasoconstriction in Ca2+-free medium.

Danshensu sodium (Dan shen suan A) is a phenolic compound with oral bioactivity that activates Nrf2/HO-1 and inhibits the NF-κB pathway. It reduces reactive oxygen species (ROS) production, enhances antioxidant defenses, and suppresses intrinsic apoptotic pathways. Additionally, Danshensu sodium exhibits significant antiviral activity against SARS-CoV-2 with an EC50 of 0.97 μM. It offers antioxidant, anti-apoptotic, and anti-inflammatory benefits for the lungs, presenting potential for research in COVID-19, cardiovascular, and cerebrovascular diseases.
