  • Patent number: 10035795
    Abstract: The present invention provides a phenothiazine derivative or a pharmaceutically acceptable salt thereof, a method of preparing a compound selected therefrom and a pharmaceutical composition containing the compound as an active ingredient. The phenothiazine derivative according to the present invention has an effect of inhibiting calmodulin (CaM; calcium-modulated protein) and thus helps cell death by maintaining the intracellular level of calcium in lung cancer cells at high concentration. Accordingly, the phenothiazine derivative according to the present invention can be usefully used to prevent or treat malignant tumors such as lung cancer.

  • 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.
