- Containing purine pentadiene ketone derivative synthesis method and application
-
The invention discloses a compound with an effect for resisting plant viruses, and relates to a preparation method and an application of a purine-containing pentadienone derivatives with an effect of resisting the plant viruses. A series of purine-containing pentadienone derivatives are synthesized in five steps by adopting 6-chloropurine, thiourea, absolute ethyl alcohol, methanoic acid, p-hydroxy benzaldehyde, sodium hydroxide, potassium hydroxide, acetone, hydrochloric acid, substituted aromatic aldehyde and substituted heterocyclic aldehydes as raw materials. The invention also discloses compounds A1, A3, A5, A7, A11, A12 and A17, which have a curative, protective and passivation effect on CMV, TMV and SRBSDV, and are relatively high in plant virus resistant activity and can be used for preparing new chemicals for preventing the plant virus diseases.

- THERAPEUTIC FOR HEPATIC CANCER
-
A novel pharmaceutical composition for treating or preventing hepatocellular carcinoma and a method of treatment are provided. A pharmaceutical composition for treating or preventing liver cancer is obtained by combining a chemotherapeutic agent with an anti-glypican 3 antibody. Also disclosed is a pharmaceutical composition for treating or preventing liver cancer which comprises as an active ingredient an anti-glypican 3 antibody for use in combination with a chemotherapeutic agent, or which comprises as an active ingredient a chemotherapeutic agent for use in combination with an anti-glypican 3 antibody. Using the chemotherapeutic agent and the anti-glypican 3 antibody in combination yields better therapeutic effects than using the chemotherapeutic agent alone, and mitigates side effects that arise from liver cancer treatment with the chemotherapeutic agent.

- Anti-Claudin 3 Monoclonal Antibody and Treatment and Diagnosis of Cancer Using the Same
-
Monoclonal antibodies that bind specifically to Claudin 3 expressed on cell surface are provided. The antibodies of the present invention are useful for diagnosis of cancers that have enhanced expression of Claudin 3, such as ovarian cancer, prostate cancer, breast cancer, uterine cancer, liver cancer, lung cancer, pancreatic cancer, stomach cancer, bladder cancer, and colon cancer. The present invention provides monoclonal antibodies showing cytotoxic effects against cells of these cancers. Methods for inducing cell injury in Claudin 3-expressing cells and methods for suppressing proliferation of Claudin 3-expressing cells by contacting Claudin 3-expressing cells with a Claudin 3-binding antibody are disclosed. The present application also discloses methods for diagnosis or treatment of cancers.
