Abstract: Disclosed are new thienyl[3,2-d]pyrimidin-4-one compounds shown as the general formula (I), preparation method, pharmaceutical compositions and pharmacological use thereof. The compounds are strong DPPIV (dipeptide peptidase IV) inhibitors and can treat type II diabetes through well inhibiting DPPIV indirectly increasing the content of GLP-1 in vivo and inducing a series of physiological actions in vivo. Therefore, the compounds could be developed as new promising drugs for treating diabetes.

More particularly, it relates to a compound 1,3,5,7-tetrahydroxy-8-isoprenylxanthone (TI, FIG. 1), that is naturally occurring in the plant of Garcinia esculenta Y. H. Li, and its biological activity of inhibiting nitric oxide production and microRNA 155 expression in stimulated macrophages, which can be developed as potential anti-inflammatory drugs.

Abstract: The present invention relates to a synthetic compound and its therapeutic uses.

Abstract: A novel polyisoprenylated tetracyclic xanthone, named garciesculentone B, isolated from Garcinia esculenta Y. H. Li is disclosed in the present invention. This compound is shown to have significant cytotoxicity against various cancer cells. In addition, garciesculentone B is shown to have antimigration effect on various cancer cells such as human esophageal carcinoma cell. The experimental data supports that this compound is useful for developing into an anticancer drug.

Abstract: This invention relates to the use of a compound from natural sources for therapeutic uses. More particularly, it relates to a compound, Garcimultiflorone E, naturally occurring in the plant of Garcinia esculenta Y. H. Li which has potent anti-inflammation and anti-cancer effect.

Abstract: Two novel polyprenylated benzoylphloroglucinol derivatives, garciesculentones A and C, are disclosed in the present invention. Garciesculentones A and C exhibit cytotoxicity and/or antimigration effect against various cancer cell lines. The experimental results of the present invention suggest that Garciesculentones A and C are useful for developing into anticancer drugs.

Abstract: Disclosed is a natural compound, Oblongifolin C, isolated from a natural plant comprising Garcinia species such as Garcinia yunnanesis Hu, for its effects of anti-migration and anti-invasion against cancer and its use as an anticancer drug. The treated cancers comprise cervical cancers and esophageal cancers. The cancer treatment comprises inhibition of cancer metastasis and inhibition of autophagic flux.

Abstract: The present invention relates to a novel hexahydrodibenzo[a,g]quinoline compound represented by general formula (I) and its derivatives, enantiomer, diastereoisomer, raceme and mixtures thereof, as well as pharmaceutically acceptable salts thereof. The present invention further relates to a method for preparing the compound, and the compound has good prevention and treatment effect on neurological diseases, especially diseases associated with dopamine receptor and 5-hydroxytryptamine receptor. The bioactivity experiment demonstrates that, the compound is expected to be developed into a novel and potent chemical entity for treating diseases associated with dopamine receptor and 5-hydroxytryptamine receptor, especially schizophrenia, Parkinson's disease, drug addiction, migraine and so on.

Abstract: The present invention discloses 3D-structure of SARS-CoV Viral 3CL Protease obtained through molecular simulation. The 3D-structure is used as a drug target for screening the existing medical database CMC (Comprehensive Medicinal Chemistry, MDL Information System, Inc.), and a group of compounds which have the activity of inhibiting SARS-CoV virus 3CL Protease are found. Cinanserin was tested at molecular and viral levels, and it was found to be able to inhibit the SARS-CoV viral 3CL protease and SARS-CoV viruses. Cinanserin analogs were synthesized and tested at molecular and viral levels, they were found to be able to inhibit the SARS-CoV virus 3CL Protease and SARS-CoV viruses, and may be used for treating and/or preventing SARS-CoV virus infection.

Abstract: The invention relates to pharmaceutical compositions comprising benzopyranone derivatives for the treatment of Severe Acute Respiratory Syndrome (SARS).

Abstract: The invention relates to the benzopyran compounds of formula (I), or the salts thereof, in which, the bond between 3 and 4 positions is a single or double bond; R1 represents a hydrogen atom or a C1-6 alkyl that can be substituted; R2 represents a hydrogen atom, a C1-6 alkyl that can be substituted or an aromatic carbocyclic or aromatic heterocyclic group that can be substituted. The invention also relates to a process for preparing such compounds or their salts as well as the use of such compounds or their salts in the preparation of the medicine against type II diabetes mellitus.
