1. ISOGINKGETIN (4',4'''-Dimethylamentoflavone), a compound derived from the leaves of Ginkgo biloba, to up-regulate adiponectin secretion with potency comparable to that of rosiglitazone, a known modulator of adiponectin production. 2. Isoginkgetin has anti-tumor activity, the mechanistic basis is splicing inhibition , thus, pre-mRNA splicing inhibitors may represent a novel avenue for development of new anti-cancer agents.3. Isoginkgetin can inhibit tumor cell invasion by regulating phosphatidylinositol 3-kinase/Akt-dependent matrix metalloproteinase-9 expression. 4. Isoginkgetin (0.3mg/kg ip for 3d) can reduce the level of O2·- in plasma and erythroeyte and sometimes increase the activity of SOD in anoxic rats, the action being stronger than aspirin.

4-Hydroxycanthin-6-one is a novel quinoline alkaloid isolated from the stem bark of Ailanthus altissima. Additionally, five other known compounds were identified. The structure of the new compound was established through analysis of physical and spectral data, and its absolute configuration was determined using electronic circular dichroism and quantum chemical calculations. These compounds exhibit significant inhibitory activity on lipopolysaccharide (LPS)-induced nitric oxide (NO) production in RAW 264.7 cells, indicating potential anti-inflammatory properties.

7-(4-Hydroxyphenyl)-1-phenyl-4-hepten-3-one as a beneficial compound to ameliorate the deleterious effects of Aβ on dendrite integrity and cell survival, and may provide new insights on drug discovery of Alzheimer's disease (AD).
