Epimedin A also possesses anti-inflammatory activity. Epimedin A can be used in the research of osteoporosis and inflammatory diseases.

Flupentixol is an orally active D₁/D₂ dopamine receptor antagonist and new PI3K inhibitor (PI3Kα IC₅₀=127 nM). Flupentixol shows anti-proliferative activity to cancer cells and induces apoptosis. Flupentixol can also be used in schizophrenia, anxiolytic and depressive research.

Batiraxcept (AVB-500; AVB-S6-500) is a selective, soluble AXL receptor and GAS6 inhibitor that targets the GAS6-AXL signaling axis. Batiraxcept is orally inactive and does not cross the blood-brain barrier. Batiraxcept competitively binds to GAS6 ((K_D <1 nM), preventing its interaction with the AXL receptor tyrosine kinase, thereby inhibiting downstream PI3K/AKT and MAPK signaling pathways, reducing tumor cell glycolysis, angiogenesis, and metastatic potential. Batiraxcept has demonstrated antitumor activity in preclinical models of endometrial, cholangiocarcinoma, and ovarian cancer by inhibiting tumor growth, invasion, and metastasis.

Naphthazarin (DHNQ) is a microtubule depolymerizing agent. Naphthazarin can improve motor function and reduce neuroinflammation in mouse models of Parkinson's disease. Naphthazarin can induce tumor cell apoptosis, autophagy, and cell cycle arrest. Naphthazarin can also induce erythrocyte apoptosis. Naphthazarin can be used in the research of tumors and neurodegenerative diseases.

Jujuboside B is a bioactive saponin component isolated from Ziziphi Spinosae Semen (sour jujube seed), with oral efficacy and blood-brain barrier permeability. Jujuboside B induces acute leukemia cell death and drives necroptosis apoptosis by activating the RIPK1/RIPK3/MLKL pathway. Jujuboside B upregulates the expression of NOXA, PARP and caspase-3, activates AMPK, inhibits the proliferation of breast cancer cells, and induces cell apoptosis and autophagy. Jujuboside B inhibits angiogenesis and tumor growth by blocking the VEGFR-2 signaling pathway. Jujuboside B alleviates liver injury in mice by regulating the Nrf2-STING signaling pathway. Jujuboside B alleviates liver injury by regulating anti-inflammatory responses and downregulating the expression of 11β-HSD2. Jujuboside B induces ferroptosis and overcomes radioresistance in non-small cell lung cancer via the PPARγ-ATF3-Gpx4 signaling pathway. Jujuboside B exerts inhibitory effects on platelet aggregation. Jujuboside B inhibits febrile seizures by suppressing the activity of AMPA receptors. Jujuboside B reverses chronic unpredictable mild stress-promoted tumor progression by blocking the PI3K/Akt and MAPK/ERK pathways and dephosphorylating CREB signaling. Jujuboside B is applicable to related studies on acute leukemia, breast cancer, PM_2.5-induced lung injury, hepatotoxicity, liver injury, colorectal cancer, non-small cell lung cancer, thromboembolic diseases, cardiovascular diseases associated with high platelet aggregation, febrile seizures, and depressive-like phenotypes.
