Compounds of the formula ##STR1## wherein A represents amidino group or an optionally substituted aminoethyl; R.sup.10 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 OR.sup.11 (wherein R.sup.11 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; R.sup.12 and R.sup.13 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 an agent for inhibiting adhesion of cells which comprise these compounds are desclosed. These have more potent and long lasting activities of inhibiting cell-adhesion, thus being useful as an orally administrable anti-thrombotic agent.
化合物的式子为##STR1##其中A代表一个酰胺基团或一个可选取的取代氨基乙基;R.sup.10代表从一组中选择的一种物种,该组由硝基,卤素原子,低烯基基团,低炔基基团,低烷氧羰基基团和由式子OR.sup.11表示的基团(其中R.sup.11是氢原子或低烷基基团,低烯基基团,低炔基基团,低烷酰基基团,氨基甲酰基或甲烷磺酰基,每个基团都可以取代;R.sup.12和R.sup.13分别代表氢原子,羟基,低烷氧基或卤素原子;X代表羟基,对羟基苯基基团或一个可选酯化或酰胺化的羧基基团;Y代表一个可选酯化或酰胺化的羧基基团;n表示1或2,或其盐和抑制这些化合物所组成的细胞黏附的药物被揭示。这些具有更强大和持久的抑制细胞黏附的活性,因此可作为口服抗血栓药物。
