, (2008/06/13)
Novel heterobicyclic sulfonamide and sulfonic ester derivatives represented by the following general formula(I), which exhibit an antitumor activity and are lowly toxic, and processes for the preparation thereof. A sulfonamide derivative and a sulfonic ester derivative represented by the general formula (I) or a pharmacologically acceptable salt thereof: STR1 wherein A represents a monocyclic or bicyclic aromatic ring which may be substituted; B represents a six-membered unsaturated hydrocarbon ring or a six-membered unsaturated heterocycle containing one nitrogen atom, each of which may be substituted; C represents a five-membered heterocycle containing one or two nitrogen atoms which may be substituted; W represents a single bond or a group represented by formula --CH=CH--; X represents a group represented by formula --N(R1)-- or oxygen; Y represents carbon or nitrogen; Z represents a group represented by formula --N(R2)-- or nitrogen; and R1 and R2 may be the same or different from each other and each represent hydrogen or lower alkyl.
