  • Patent number: 7910362
    Abstract: A reporter vector which can evaluate the ability of a drug to induce CYP1A2 or both of CYP1A1 and CYP1A2 and a method for evaluation of the ability of a drug to induce CYP1A2 or both of CYP1A1 and CYP1A2 by using the reporter vector. A reporter system which can evaluate the ability of a drug capable of inducing CYP1A2 or both of CYP1A1 and CYP1A2 is completed by constructing a reporter vector having a reporter gene linked to the 3? end of a region between CYP1A1 and CYP1A2 or a reporter vector having different reporter genes linked to the both ends of the region, respectively, so as to sandwich the region, and a reporter vector having a deletion mutation in the region, and confirming that the expression of a reporter molecule is increased by the drug capable of inducing CYP1A2 or both of CYP1A1 and CYP1A2 in the reporter system using the reporter vector.

  • Publication number: 20110029296
    Abstract: A ring structure of a predicted target compound which is in a two-dimensional structural formula is arranged so as to be in an identical position as a ring structure of a template produced by superimposing two-dimensional structural formulae of compounds capable of forming a complex with a predetermined enzyme. Among predicted target compounds overlapping with a metabolic target site of the template, predicted target compounds other than those determined as being unable to access a metabolic active center site of the enzyme, or those having the same charge as that of the metabolic active center site, are determined to be metabolizable compounds. Based on the level of contribution of each atom included in the template during a metabolic reaction of the enzyme, a structural formula of a compound obtained after the metabolic reaction of the metabolizable compound whose metabolic target site has been determined is determined.
