  • Patent number: 11555091
    Abstract: This invention generally provides composition for making a polyurethane foam with reduced aldehyde emission and more specially to composition useful in means of transport such as interior part of cars, wherein composition is comprising: (a) a polyfunctional isocyanate; (b) an isocyanate reactive composition; and (c) a compound of the formula (I) or (II), wherein the compound (c) is present by weight percentage in the composition in an amount ranging from about 0.001 to about 10, preferably from about 0.01 to about 5, and more preferably from about 0.05 to about 2 based on the total weight of the composition. The compositions can reduce aldehyde emission, especially acetaldehyde emission in the PU foam and has no obvious influence on the mechanic properties of the foam.

  • 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.
