Hot Natural Products & Bioactive Compounds

1. Methyl orsellinate is a phytotoxic compound, it can cause significant inhibition of radicle growth of Amaranthus hypochondriacus and Echinochloa crus-galli, interact with bovine-brain calmodulin and inhibit the activation of the calmodulin-dependent enzyme cAMP phosphodiesterase.
2. Methyl orsellinate exhibits antifungal activity.
3. Methyl orsellinate can inhibit PTP1B activity with 50% inhibitory concentration values of 277 +/- 8.6 microM, the selective inhibition of PTP1B has been widely recognized as a potential drug target for the treatment of type 2 diabetes and obesity, methyl orsellinate may can treat the type 2 diabetes and obesity.

1. Ethyl glucoside is a shale inhibitor for water base drilling fluids.
2. Ethyl glucoside is a multifunctional initiator for enzyme-catalyzed regioselective lactone ring-opening polymerization.

1. Medicarpin, a legume phytoalexin, acts as an estrogen receptor (ER) agonist, can stimulate osteoblast differentiation likely via ERβ, promote achievement of peak bone mass, and is devoid of uterine estrogenicity; in addition, given its excellent oral bioavailability, it can be potential osteogenic agent.
2. Medicarpin exhibits no uterine estrogenicity, however it can inhibit osteoclastogenesis and has nonestrogenic bone conserving effect in ovariectomized mice.
3. Medicarpin and maackiain and two of their biosynthetic precursors inhibit the constitutive and phenobarbital (PB)-induced types of AHH, but have little effect on the 3-methylcholanthrene (MC)-induced type of AHH.
4. Medicarpin sensitizes myeloid leukemia cells to TRAIL-induced apoptosis through the induction of DR5 and activation of the ROS-JNK-CHOP pathway.
5. Medicarpin has antifungal activity.

1. Myricanone has anticancer activity.
2. Myricanone has apoptosis-promoting ability by triggering caspase activation, and suppression of cell proliferation by down-regulation of NF-κB and STAT3 signalling cascades.
3. Myricanone displays significant antioxidant activity.
4. Myricanone shows in vitro testosterone 5alpha-reductase inhibitory activity and in vivo anti-androgenic activity using growth of flank organ in castrated Syrian hamsters and/or hair regrowth after shaving in testosterone-treated C57Black/6CrSlc mice.

1. Kaempferol 3-neohesperidoside has insulin-like properties in terms of glucose lowering.
2. Kaempferol 3-neohesperidoside stimulates glucose uptake in the rat soleus muscle via the PI3K and PKC pathways and, at least in part, independently of MEK pathways and the synthesis of new glucose transporters.
3. Kaempferol 3-neohesperidoside possesses not only a significant anticancer effect against HepG2 cells, but also an effective and a dose dependent hepatoprotective and antioxidant activities due to the presence of flavonoids content.

Oleuropein exhibits anti-ischemic, antioxidative, hypolipidemic, in vitro antimycoplasmal , anti-inflammatory, and anti-cancer effects., it also may be helpful in the prevention of diabetic complications associated with oxidative stress. Oleuropein prevents oxidative myocardial injury induced by ischemia and reperfusion, and reduces viremia in duck hepatitis B virus (DHBV)-infected ducks. Oleuropein reduces TLR and MAPK signaling.

1. Fraxamoside shows significant free radical scavenging effect against DPPH(EC50=62.6 uM).
2. Fraxamoside is a xanthine oxidase inhibitor (XOI) comparable in potency in vitro to the standard antigout drug allopurinol.

1. Cajanin has strong mitogenic as well as differentiation-promoting effects on osteoblasts that involved subsequent activation of MEK-Erk and Akt pathways.
2. Cajanin has potential hypolipidemic effects,possibly via up-regulating the ABCA1 protein expression,subsequently resulting in increased macrophage cholesterol efflux and RCT.
3. Cajanin can significantly improve basal glucose uptake in HepG2 cells, its improving effect is concentration dependent, it exhibits effects stronger than that of rosiglitazone, which has been used as an antidiabetic drug.
