摘要:
Novel bicyclic heterocyclic sulfonamide and sulfonic ester derivatives represented by general formula (I) having an antitumor activity and a reduced toxicity, pharmacologically acceptable salts thereof, and a process for producing the same; wherein ring A represents an optionally substituted mono- or bicyclic aromatic group; ring B represents an optionally substituted 6-membered unsaturated hydrocarbon ring or 6-membered unsaturated heterocyclic group containing one nitrogen atom; ring C represents an optionally substituted 5-membered heterocyclic group containing one or two nitrogen atoms; W represents a single bond or -CH=CH-; X represents -NR¹- or oxygen; Y represents carbon or nitrogen; Z represents -NR²- or nitrogen; and R¹ and R² represent each independently hydrogen or lower alkyl.
摘要:
An appetite-stimulating agent and a therapeutic agent for anorexia, each comprising, as an active ingredient, a sulfonamide derivative or sulfonic acid ester derivative represented by the following general formula (I): wherein the ring A represents a monocyclic or bicyclic aromatic ring which may be substituted, the ring B represents a 6-membered unsaturated hydrocarbon ring or a 6-membered unsaturated heterocyclic ring containing one nitrogen atom as a heteroatom, each of which may be substituted, the ring C represents a 5-membered heterocyclic ring containing one or two nitrogen atoms, which may be substituted, W represents a single bond or -CH=CH-, X represents -N(R 1 )- or an oxygen atom, Y represents a carbon atom or a nitrogen atom, Z represents -N(R 2 )- or a nitrogen atom, and R 1 and R 2 may be identical or different and each represents a hydrogen atom or a lower alkyl group, or a pharmacologically acceptable salt thereof, or a hydrate thereof.
摘要:
Novel fused polycyclic heterocycle derivatives having excellent antitumor effects and a process for producing the same. A compound represented by the following general formula (I) or pharmacologically acceptable salts thereof: wherein the ring A represents an optionally substituted monocyclic aromatic ring or a dicyclic fused ring in which at least one of the rings is an aromatic ring; the ring B represents pyrrole, 4H-1,4-oxazine, 4H-1,4-thiazine or 4(1H)-pyridone; the ring C represents an optionally substituted, monocyclic or dicyclic fused aromatic ring; and Y represents a group represented by the formula -e-f (wherein e represents a lower alkylene; and f represents amidino, guanidino or amino optionally substituted by optionally hydroxylated or optionally lower-alkylaminated lower alkyl; provided that the cases where the rings A and B are both optionally substituted monocyclic aromatic rings are excluded. Which has an excellent antitumor activity.
