Integrin expression inhibitors

摘要

The present invention provides an integrin expression inhibitor, and an agent for treating arterial sclerosis, psoriasis, cancer, retinal angiogenesis, diabetic retinopathy or inflammatory diseases, an anticoagulant, or a cancer metastasis suppressor on the basis of an integrin inhibitory action. Namely, it provides an integrin expression inhibitor comprising, as an active ingredient, a sulfonamide compound represented by the following formula (I), a pharmacologically acceptable salt thereof or a hydrate of them. In the formula, B means a C6-C10 aryl ring or 6- to 10-membered heteroaryl ring which may have a substituent and in which a part of the ring may be saturated; K means a single bond, -CH=CH- or - (CR<4b>R<5b>)m- (wherein R<4b> and R<5b> are the same as or different from each other and each means hydrogen atom or a C1-C4 alkyl group; and m means an integer of 1 or 2); R<1> means hydrogen atom or a C1-C6 alkyl group; Z means a single bond or -CO-NH-; and R means a C6-C10 aryl ring or 6- to 10-membered heteroaryl ring which may have a substituent and in which a part of the ring may be saturated, respectively.
