Sulfonyl derivatives represented by the following general formula (I): Q1-Q2-T1-Q3-SO2-QA and drugs containing the same (wherein Q1 is an optionally substituted, saturated or unsaturated, five- or six-membered cyclic hydrocarbon group, a five- or six-membered heterocyclic group, or the like; Q2 is a single band, oxygen, sulfur, C1-C6 alkylene or the like; QA is optionally substituted arylalkenyl, heteroarylalkenyl or the like; and T1 is carbonyl or the like). These compounds have potent FXa-inhibitory effects and promptly exert satisfactory and persistent antithrombotic effects through oral administration, thus being useful as anticoagulant agents little accompanied with side effects.
Described in the present invention are a sulfonyl derivative represented by the following formula (I):

[wherein Q
1
represents a saturated or unsaturated 5- or 6-membered cyclic hydrocarbon group, 5- or 6-membered heterocyclic group, dicyclic fused ring or tricyclic fused ring group which may have a substituent;
Q
2
represents a single bond, an oxygen atom, a sulfur atom, a linear or branched C

alkylene group or the like;
Q
A
represents an arylalkenyl group which may have a substituent or a heteroarylalkenyl group which may have a substituent; and
T
1
represents a carbonyl group or the like] and a medicament comprising the same. The compound has strong FXa inhibitory action, provides prompt, sufficient and long-lasting anti-thrombus effects when orally administered, and has low side effects and is therefore useful as an excellent anticoagulant.
