Stevisalioside A (Compound 2), isolated from the roots of Stevia serrata, is an orally active antidiabetic agent that inhibits Protein Tyrosine Phosphatase 1B (PTP1B) with an IC50 value of 526.8 μM. It effectively lowers blood glucose levels and attenuates the postprandial peak observed in oral glucose and insulin tolerance tests in Streptozotocin-induced hyperglycemic mice [1].

PP5-IN-1 is a potent and competitive serine/threonine protein phosphatase-5 (PP5) inhibitor with potential anticancer activity that induces apoptosis in cancer cells.

RMC-4630 (SHP2-IN-7) is an inhibitor of SHP2.

Disodium monofluorophosphate (NSC248) is a competitive inhibitor of pyruvate kinase and alkaline phosphatase, which also irreversibly inhibits phosphorylase phosphatase.

1. Kuwanon G (Moracenin B) as dual inhibitors of PTP1B and α-glucosidase enzymes, as well as insulin sensitizers, it may potentially be utilized as an effective treatment for Type II diabetes mellitus. 2. Kuwanon G has anti-inflammatory activity, it can attenuate atherosclerosis through inhibiting foam cell formation and inflammatory response. 3. Kuwanon G is a potent inhibitor of Mycobacterium tuberculosis protein tyrosine phosphatase B. 4. Kuwanon G shows acetylcholinesterase (AChE) and butyrylcholinesterase(BChE) inhibitory activities, it may be a promising candidate for preventive and therapeutic agents for Alzheimer's disease. 5. Kuwanon G prevents the pathological progression of allergic asthma through the inhibition of lung destruction by inflammation and immune stimulation. 6. Kuwanon G has antibacterial activity against oral pathogens. 7. Kuwanon G is a specific antagonist for the GRP-preferring receptor and can be useful for studying the physiological and pathological role of GRP.
