ABSTRACT:
Novel tricyclic heterocyclic sulfonamide derivatives and sulfonic ester derivatives which have excellent antitumor activity and are represented by the following general formula (I) and processes for producing the same are provided. The present sulfonamide derivatives or a sulfonic ester derivatives are represented by the following general formula (I): ##STR1## wherein G represents an aromatic 5- or 6-membered ring; L represents 0 or --N(R.sup.1)-- and --R.sup.1 represents hydrogen or lower alkyl; and M represents a tricyclic structure selected from among the following; ##STR2## rings A and B each represent an unsaturated 5- or 5 -membered ring; X represents N(R.sup.2) wherein R.sup.2 represents hydrogen or lower alkyl, or NHCO; Y represents 0, S(O).sub.n, C(R.sup.3) (R.sup.4), C(O), N(R.sup.5), CH(R.sup.6)CH(R.sup.7), C(R.sup.8).dbd.C(R.sup.9), N(R.sup.10) C(O), N.dbd.CR.sup.11), OCH(R.sup.12), S(O).sub.n CH(R.sup.13) or N(R.sup.14)CH(R.sup.15); Z represents nitrogen or C(R.sup.16); and n represents 0, 1 or 2, R.sup.3 to R.sub.13, R.sup.15 and R.sup.16 each represent hydrogen or lower alkyl, and R.sup.14 represents hydrogen, lower alkyl or lower acyl.
