  • Patent number: 9752151
    Abstract: The present invention relates to a composition for treatment or metastasis suppression of cancers which includes a p34 expression inhibitor or activity inhibitor as an active ingredient. According to the present invention, the p34 protein knock-down causes monoubiquitination of PTEN and accordingly nuclear localization of PTEN is induced, as a result, an Akt pathway which is related to survival, proliferation, invasive properties and metastatic properties of tumors is inhibited, and thus there is an effect of significantly reducing clonogenic potential and tumor forming potential of various cancer cells which simultaneously express PTEN and NEDD4-1. Consequently, the p34 gene expression inhibitor or p34 protein activity inhibitor according to the present invention can be effectively used as a treatment agent or a metastasis suppression agent for cancers.

  • Patent number: 9447054
    Abstract: Disclosed is an anticancer supplement agent including a benzo[d]oxazole derivative as an effective ingredient. The benzo[d]oxazole derivative, which is a nuclear factor E2-related factor 2 (Nrf2) inhibitor, is capable of inhibiting activity of Nrf2 that induces an antioxidant enzyme to remove reactive oxygen species (ROS) that kills a cancer cell, thereby increasing production of ROS. Therefore, the benzo[d]oxazole derivative can be used as an anticancer supplement agent that shows therapeutic effects in anticancer agent therapy or radiation therapy, and in this regard, the benzo[d]oxazole derivative can overcome tolerance of the cancer cell to anticancer agent therapy or radiation therapy and enhance apoptotic effects on the cancer cell.

  • Patent number: 8793078
    Abstract: The present invention provides a method for constructing a database of atomic fingerprint descriptors. The invention provides a method for predicting activation energy using an atomic fingerprint descriptor and an atomic descriptor, the method comprising the steps of: (i) calculating the atomic fingerprint descriptor of a substrate; (ii) comparing the calculated atomic fingerprint descriptor with the constructed atomic fingerprint descriptor database to select an atomic position where cytochrome P450-mediated metabolism occurs; and (iii) predicting activation energy for the selected atomic position using an atomic descriptor. Also, the invention provides a method of predicting the activation energy of CYP450-mediated phase I metabolism using effective atomic descriptors.
