The dried whole plant of Meehania fargesii (H. LéV.) C. Y. WU is utilized as an antipyretic and antidote for poison in China. Water soluble fractions, obtained from an 80% acetone extract of the whole plant, showed hyaluronidase inhibitory activity. From these fractions, hyaluronidase inhibitors were isolated along with two new spermidine alkaloids (meefarnines A and B), four new flavone glycosides (fargenins A—D), and 10 known compounds. The structure of each was elucidated by spectroscopic methods.

Melonoside A (1), the first representative of a new class of ω-glycosylated fattyacid amides, was isolated from the Far Eastern marine sponge Melonanchora kobjakovae. The structure of 1, including absolute configuration, was established using detailed analysis of 1D and 2D NMR, CD, and mass spectra as well as chemical transformations. Compound 1 induces autophagy of human cisplatin-resistant germinal

Fivenewtriterpenoidsaponins, oleiferosides P–T (1–5) were isolated from the EtOH extract of the roots of Camellia oleifera C. Abel. The structures of saponins 1–5 were elucidated on the basis of integrated spectroscopic techniques. All the compounds were characterized to be oleanane-type saponins with sugar moieties linked to the C-3 of the aglycone. By using the MTT assay, an in vitro analysis

An object of the present invention is to develop a method of enhancing the cognitive ability of a brain to fundamentally cure a disease. It has been found out that, by using a medicament for treating or preventing a disease including a combination of a major tranquilizer, and vitamin C or a salt thereof and, if necessary, drip infusion, an antidepressant and an iron agent, the cognitive ability of a brain is enhanced, thus, an arbitrary disease including various cancers can be treated. The present invention also provides a method for treating or preventing a disease including a step of administering a major tranquilizer, and vitamin C or a salt thereof to a subject suffering from the disease.
