Novel tricyclic heterocyclic sulfonamide derivatives and sulfonic ester derivatives which have each an antitumor action and are represented by the following general formula (I) and processes for producing the same are provided. These compounds have each an excellent antitumor activity. A sulfonamide derivative or a sulfonic ester derivative represented by the following general formula (I): Image (I) {G represents an aromatic 5- or 6-membered ring; L represents O or -N(R1)- (R1 represents hydrogen or lower alkyl); and M represents a tricyclic structure selected from among the following ones; Image Image Image (a) (b) (c) Image Image Image (d) (e) (f) [rings A and B represent each an unsaturated 5- or 6-membered ring; X represents N(R2), (wherein R2 represents hydrogen or lower alkyl), or NHCO; Y represents O, S(O)n, C(R3)(R4), C(O), N(R5), CH(R6)CH(R7). C(R8)=C(R9), N(R10)C(O), N=C(R11), OCH(R12), S(O)nCH(R13) or N(R14)CH(R15); Z represents nitrogen or C(R16); (n represents 0, 1 or 2, R3 to R13, R15 and R16 each represents hydrogen or lower alkyl, and R14 represents hydrogen, lower alkyl or lower acyl.)]} - 105 -
