Abstract
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): ##STR1## {G represents an aromatic 5- or 6-membered ring; L represents 0 or --N(R.sup.1)-- (R.sup.1 represents hydrogen or lower alky); and M represents a tricyclic structure selected from among the following ones; ##STR2## rings A and B represent each an unsaturated 5- or 6-membered ring; X represents N(R.sup.2), (wherein R.sup.2 represents hydrogen or lower alkyl), or NHCO; PA2 Y represents O, 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.C(R.sup.11), OCH(R.sup.12), S(O).sub.n CH(R.sup.13) or N(R.sup.14)CH(R.sup.15); PA2 Z represents nitrogen or C(R.sup.16) PA3 (n represents 0, 1 or 2, R.sup.3 to R.sup.13, R.sup.15 and R.sup.16 each represents hydrogen or lower alkyl, and R.sup.14 represents hydrogen, lower alkyl or …
