GSK189254A (GSK189254 free base) is a novel, potent and selective histamine H3 receptor antagonist with pKi values of 9.59-9.90 and 8.51-9.17 for human and rat H3, respectively.

Purpurogallin is a naturally phenol extracted from the plants of Quercus spp, has potent xanthine oxidase (XO) inhibitory activity with an IC50 of 0.2 µM. Purpurogallin has antioxidant and anti-inflammatory effects.

SKA-121 is a selective KCa3.1 activator. SKA-121 exhibits EC50s of 109 nM and 4.4 μM for KCa3.1 and KCa2.3, respectively.

Thioridazine, an antagonist of the dopamine receptor D2 family proteins, exhibits potent anti-psychotic and anti-anxiety activities. Thioridazine is also a potent inhibitor of PI3K-Akt-mTOR signaling pathways with anti-angiogenic effect. Thioridazine shows antiproliferative and apoptosis induction effects in various types of cancer cells, with specificity on targeting cancer stem cells (CSCs).

TZ9 is a selective Rad6 inhibitor. TZ9 inhibits Rad6B-induced histone H2A ubiquitination, downregulates intracellular β-catenin, induces G2-M arrest and apoptosis, and inhibits the proliferation and migration of metastatic human breast cancer cells.

Rostafuroxin (PST 2238), a digitoxigenin derivative, is an orally active and potent Na+,K+-ATPase (ATP1A1) antognist. Rostafuroxin binds specifically to the ATP1A1 extracellular domain and blocks respiratory syncytial virus (RSV)-triggered EGFR Tyr845 phosphorylation. Rostafuroxin has antihypertensive and anti-RSV activity.

(±)-Ibipinabant ((±)-SLV319) is the racemate of SLV319. (±)-Ibipinabant ((±)-SLV319) is a potent and selective cannabinoid-1 (CB-1) receptor antagonist with an IC50 of 22 nM.

Moringin is a potent and selective TRPA1 ion channel natural agonist with an EC50 of 3.14 μM. Moringin does not activate or activates very weakly the vanilloids somatosensory channels TRPV1, TRPV2, TRPV3 and TRPV4, and the melastatin cooling receptor TRPM8. Moringin has hypoglycemic, antimicrobial, anti-inflammatory, anticancer and neuroprotection activities.

Obovatol is a biphenyl ether lignan isolated from the leaves of Magnolia obovata Thunb.
