  • Patent number: 10092592
    Abstract: The present invention belongs to the field of medicine technology, particularly relating to an application of cyclic dinucleotide (cGAMP) in tumor treatment. Researches carried out in the present invention show that, cGAMP can inhibit growth of many types of tumor cells, with remarkable anti-tumor effect, thus, it can be used in preparation of anti-tumor drugs; and the prepared anti-tumor drugs have low toxicity and favorable effect. Proved by a subcutaneous tumor model in nude mice, cGAMP has a remarkable inhibition effect on tumors of human gastric carcinoma cell line MNK-45, human lung adenocarcinoma cell line A549, human colorectal carcinoma cell line Lovo, human hepatocellular carcinoma cell line SMMC-7721, human prostatic carcinoma cell line PC-3 and human pancreatic carcinoma cell SW1990, which are subcutaneously implanted in nude mice, and also proved by animal acute toxicity experiment. cGAMP has a relatively low acute toxicity, therefore and may be used for preparing anti-tumor drugs.

  • Patent number: 9790502
    Abstract: This invention is directed to a RNA interference (RNAi) agent and the use of that RNAi agent to treat hepatitis B infection in individuals, as well as pharmaceutical compositions containing the RNAi agents of the invention. The RNAi agents, or constructs for expressing them are utilized to inhibit expression of at least one Hepatitis B virus (HBV) gene, where the agent comprises an effector sequence complementary to or substantially complementary to a predicted sequence transcribed from a target region. In some forms of the invention, the agent has more than one effector sequence. Multiple effectors may target the same region of an HBV gene, different (possibly overlapping) regions of the same gene and/or different HBV genes.
