  • Patent number: 10493136
    Abstract: An immunity-inducing agent comprising as an effective ingredient a specific polypeptide is disclosed. These polypeptides were isolated, by the SEREX method using a cDNA library derived from canine testis and serum from a cancer-bearing dog, as a polypeptide which binds to an antibody existing specifically in serum derived from a cancer-bearing living body. The polypeptides can induce immunity in a living body and cause regression of a tumor in a cancer-bearing living body. Therefore, these polypeptides are especially effective as a therapeutic and/or prophylactic agent for a cancer(s).

  • Publication number: 20180256495
    Abstract: It has been demanded to develop a formulation for a novel external preparation having excellent transdermal absorption of a basic pharmacologically active component contained therein. It is found that the lipid solubility (log P values) of a basic pharmacologically active component and an organic acid (particularly a fatty acid) contribute significantly to the transdermal absorption of the basic pharmacologically active component in the selection of proper combinations of the basic pharmacologically active component and the organic acid. Namely, it is found that superior transdermal absorption of a basic pharmacologically active component having a lipid solubility level of 0.5 to 5 can be achieved by forming a salt of the component with a fatty acid having a lipid solubility level of ?1 to 4. Thus, it becomes possible to provide a novel external preparation having excellent transdermal absorption properties.

  • Publication number: 20150216796
    Abstract: The present invention provides a microneedle array which makes it possible to quantitatively and accurately inject a drug into the skin. The present inventors have found that when a microneedle array is coated with a drug composition comprising a drug and an additive which has a Vickers hardness of about 3 or more, the removal of the drug can be avoided, and the drug can be surely inserted into the skin along with the microneedle array. As a result, the microneedle array coated with the drug composition of the present invention can be used in the fields in which the drug is required to be administrated with high quantitative performance even when the drug is contained in small amounts, e.g., the administration of a vaccine, and the scope of application of the microneedle array can be extended.
