Bacopaside I is an orally active aquaporin AQP1 inhibitor and PKC modulator with neuroprotective and anticancer activities. Bacopaside I specifically blocks the water channel and cGMP-gated ion channel activities of AQP1 without affecting AQP4, thereby inhibiting the migration of colon cancer cells expressing AQP1. Bacopaside I activates the Akt pathway by interacting with PI3K, specifically inhibits MAO-A, effectively alleviates neuron necrosis and apoptosis induced by oxygen-glucose deprivation, reduces oxidative stress, and regulates the surface expression of neuroreceptors. When combined with Bacopaside II (HY-N6016), Bacopaside I significantly reduces the viability, proliferation and invasion ability of breast cancer cells, and binds to the pregnane X receptor (PXR). Bacopaside I is applicable to the research of colon cancer, breast cancer, vascular dementia, cerebral ischemia and other related diseases.

Aberrant tau ligand 1 is a tau protein ligand. Aberrant tau ligand 1 engages tau and CRBN to trigger proteasomal degradation. Aberrant tau ligand 1 can be used for synthesis PROTACs, such as QC-01–175 (HY-134850).

Methyl isoplatydesmine is a cholinesterase inhibitor with spasmolytic activity, with a K_i value of 30.0 μM against electric eel acetylcholinesterase and a K_i value of 19.0 μM against horse serum butyrylcholinesterase. Methyl isoplatydesmine mediates spasmolytic activity by blocking voltage-dependent calcium channels. Methyl isoplatydesmine can be used in the research of Alzheimer's disease and related dementias.
