Constitution: a novel compound represented by general formula (1), wherein R<1> represents -OR<3> (R<3> being H or alkyl), -NR<4>R<5> (R<4> and R<5> being each H, alkyl or alkoxy), -NHCH(R<6>)COR<7> (R<6> being H or alkyl, and R<7> being alkyl), -NHCH(R<6>)COOR<8>(R<8> being alkyl) or -NHCH(R<6>)CONR<9>R<1><0> (R<9> and R<1><0> being each H or alkyl, or alternatively NR<9>R<1><0> being a heterocyclic group as a whole); and R<2> represents H, alkyl or aralkyl. Effect: since the compound has an inhibitory activity type IV collagenase, it is useful as an inhibitor against vascularization, cancer infiltration or cancer metastasis. <CHEM> |
