Compounds of the formula
[wherein A represents amidino group or an optionally substituted aminoethyl; R¹⁰ represents one species selected from a group consisting of nitro group, a halogen atom, a lower alkenyl group, a lower alkynyl group, a lower alkyloxycarbonyl group and a group represented by the formula OR¹¹ (wherein R¹¹ is hydrogen atom or a lower alkyl group, a lower alkenyl group, a lower alkynyl group, a lower alkanoyl group, a carbamoyl group or a methanesulfonyl group, each of which may be substituted; R¹² and R¹³ respectively represent hydrogen atom, hydroxyl group, a lower alkoxy group or a halogen atom; X represents hydroxyl group, p-hydroxyphenyl group or an optionally esterified or amidated carboxyl group; Y represents an optionally esterified or amidated carboxyl group; and n denotes 1 or 2], or a salt thereof and agent for inhibiting adhesion of cells, which comprise said compound, and these have more potent and long lasting activities of inhibiting cell-adhesion, thus being useful as an orally administrable anti-thrombotic agent.
式中的化合物
[其中 A 代表脒基或任选取代的氨基乙基;R¹⁰ 代表一种选自硝基、卤素原子、低级烯基、低级炔基、低级烷氧羰基和式 OR¹¹ 所代表的基团(其中 R¹¹ 为氢原子或低级烷基、低级烯基、低级炔基、低级烷酰基、氨基甲酰基或甲磺酰基,每个基团均可被取代;R¹² 和 R¹³ 分别代表氢原子、羟基、低级烷氧基或卤原子;X 代表羟基、对羟基苯基或任选酯化或酰胺化的羧基;Y 代表任选酯化或酰胺化的羧基;和 n 表示 1 或 2],或其盐和抑制细胞粘附的制剂,其中包括所述化合物,这些化合物具有更强和更持久的抑制细胞粘附的活性,因此可用作口服抗血栓形成剂。
