Gymnoside II
Gymnoside II is one of the main bioactive constituents isolated from Bletilla striata. Gymnoside II inhibits nano SiO2-induced A549 cell viability reduction, apoptosis, and ROS generation by activating Nrf2. Gymnoside II upregulates HO-1 and γ-GCSc, while downregulating the Bax/Bcl-2 ratio. Gymnoside II is applicable for research on nano SiO2-induced pulmonary injury.

Gymnoside II (1–50 µM; 24 h) alleviated the reduction in A549 cell viability induced by nano-level SiO2 and did not affect the proliferation of normal cells [1].
Gymnoside II (25 μM; pre-treatment for 2 h + co-culture for 24 h) inhibits nm SiO2-induced apoptosis in A549 cells by normalizing the expression of apoptotic proteins and reducing the percentage of apoptotic cells [1].
Gymnoside II (25 µM; pretreatment for 2 h followed by co-culture for 24 h) reduces nm SiO2-induced ROS generation in A549 cells[1].
Gymnoside II (25 µM; pretreatment for 2 h followed by coculture for 24 h) upregulates the expression of Nrf2, HO-1, and γ-GCSc and activates the Nrf2 signaling pathway in A549 cells[1].
