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.

photocycloaddition of 1,3-dihydroisobenzofuran and 1,3-dihydroisoindole-2-carboxylic acid methyl ester with cyclopentene and 2,5-dihydrofuran affords two new classes of photoadducts. The photoadducts were identified by the SORT&gen algorithm as NewMolecularEntities in two-dimensional scaffold space. The structures of the adducts were established by NMR spectroscopy and the stereo-, regio- and chemoselectivity

The racemic
indolizidine-1,2-dio1 (6) was synthesized and found to be a weak, in vitro inhibitor of acid α-D-mannosidase (Km 0.75 × 10-2) and acid
α-D-glucosidase (Km 1.1 × 10-2
M).
Sulfonyl derivatives represented by general formula (I), salts of the same, and solvates of both: and application of them as drugs: [wherein R1 is hydrogen, hydroxyl, nitro or the like; R2 and R3 are each independently hydrogen, halogeno or the like; R4 and R5 are each dependently hydrogen, halogeno or the like; Q1 is an optionally substituted saturated or unsaturated 5- or 6-membered cyclic hydrocarbon group or the like; Q2 is a single bond, oxygen or the like; Q3 is, e.g., a group represented by formula (a): T1 is carbonyl or the like; and X1 and X2 are each independently methylidyne or nitrogen]. These compounds exhibit potent Fxa inhibiting activities and serve as excellent anticoagulants which speedily exert satisfactory and persistent anti-thrombotic effects through oral administration and little cause adverse effects.

[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.
