Provided is a cell proliferation inhibitor comprising a compound of the formula (1) or a pharmacologically acceptable salt thereof:wherein J<sup>1</sup>and J<sup>2</sup>each represent CH or N, with the proviso that J<sup>1</sup>and J<sup>2</sup>are not simultaneously CH; r represents 0 to 4; each R<sup>101</sup>is the same or different when r is 2 or more, and R<sup>101</sup>represents a C<sub>1-6</sub>alkyl group optionally substituted with a halogen atom or the like; s represents 0 to 5; each R<sup>102</sup>is the same or different when s is 2 or more, and R<sup>102</sup>represents a halogen atom or the like; R<sup>103</sup>represents a hydrogen atom, a C<sub>1-6</sub>alkyl group, a C<sub>3-6</sub>cycloalkyl group, or a C<sub>3-6</sub>cycloalkyl C<sub>1-6</sub>alkyl group; and R<sup>101</sup>and R<sup>103</sup>are optionally linked together to form a five- to seven-membered ring hetero ring when R<sup>101</sup>is present at the 8-position. |
