Using fragment-based screening of a focused fragment library, 2-aminoquinoline 1 was identified as an initial hit for BACE1. Further SAR development was supported by X-ray structures of BACE1 cocrystallized with various ligands and molecular modeling studies to expedite the discovery of potent compounds. These strategies enabled us to integrate the C-3 side chain on 2-aminoquinoline 1 extending deep into the P2′ binding pocket of BACE1 and enhancing the ligand's potency. We were able to improve the BACE1 potency to subnanomolar range, over 106-fold more potent than the initial hit (900 μM). Further elaboration of the physical properties of the lead compounds to those more consistent with good blood-brain barrier permeability led to inhibitors with greatly improved cellular activity and permeability. Compound 59 showed an IC50 value of 11 nM on BACE1 and cellular activity of 80 nM. This compound was advanced into rat pharmacokinetic and pharmacodynamic studies and demonstrated significant reduction of Aβ levels in cerebrospinal fluid (CSF).

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 —(CR4bR5b)mb— (wherein R4b and R5b are the same as or different from each other and each means hydrogen atom or a C1-C4 alkyl group; and mb means an integer of 1 or 2); R1 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.
