The invention relates to a compound of general formula (I-0): wherein R1 means a C1-C6 alkyl group, a C2-C6 alkenyl group, a C2-C6 alkynyl group, or a C3-C6 cycloalkyl group; R2, R3, R4 and R5 mean a hydrogen atom, a halogen atom, a C1-C6 alkyl group, a halo-C1-C6 alkyl group, a C1-C6 alkoxy group, or a halo-C1-C6 alkoxy group; R6 means a hydrogen atom, or a C1-C6 alkyl group; R7a means a hydrogen atom, a halogen atom, a C1-C6 alkyl group, a halo-C1-C6 alkyl group, a C1-C6 alkoxy group, a hydroxy-C1-C6 alkyl group, -Q2-N(R1c)R1d or a nitrogen-containing heterocyclic group; R8a means a hydrogen atom, a halogen atom, a C1-C6 alkyl group, a halo-C1-C6 alkyl group, a C1-C6 alkoxy group or a hydroxy-C1-C6 alkyl group; or R7a and R8a form, as taken together, a C2-C6 alkylene group, or R7a and R8a and the ring atoms to which they bond may form a spiro ring or a bicyclo ring; and X and Y mean a methine group or a nitrogen atom. The compound of the invention has, based on its excellent Wee1 kinase-inhibitory effect, a cell growth-inhibitory effect and an additive/synergistic effect with any other anticancer agent, and is therefore useful in the field of medicine.
