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.

1-Hydroxy-2-butanone, a natural product extractable from bamboo juice and tomato leaves, exhibits anti-tuberculosis activity.

Collinin is a coumarin that has been found in Z. schinifolium and has diverse biological activities.1,2,3,4 It is active against drug-susceptible and -resistant strains of M. tuberculosis (MIC50s = 3.13-6.25 μg/ml).1 Collinin inhibits LPS-induced nitric oxide (NO) production (IC50 = 5.9 μM) and reduces COX-2 protein levels in RAW 264.7 cells.2 It completely inhibits aggregation of isolated rabbit platelets induced by arachidonic acid , collagen, or platelet activating factor (PAF) when used at a concentration of 100 μM.3 Dietary administration of collinin (0.05% w/w) reduces the number of mice with tumors and the number of tumors per mouse in a mouse model of colitis-related carcinogenesis.4 |1.

1. (+)-(3R,8S)-Falcarindiol is a potential new anticancer agent that exerts its activity through inducing ER stress and apoptosis. 2. Falcarindiol induces immunosuppressive effects in vitro and in vivo and might be a novel therapy for autoimmune or allergic diseases. 3. Falcarindiol has protective effect against CCl(4) toxicity , in part, be explained by anti-lipid peroxidation activity associated with the induction of the GSTs including GSTA4.
