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.
该公式化合物为##STR1##其中A代表酰胺基团或可选择取代的
氨基乙基;R.sup.10代表从硝基、卤素原子、较低的烯基基团、较低的炔基基团、较低的烷氧羰基团和由OR.sup.11(其中R.sup.11为氢原子或较低的烷基基团、较低的烯基基团、较低的炔基基团、较低的烷酰氧基团、羰基基团或甲磺酰基团,每个基团都可以被取代)表示的基团中选择的一种物种;R.sup.12和R.sup.13分别代表氢原子、羟基、较低的烷氧基团或卤素原子;X代表羟基、对羟基苯基基团或可酯化或酰化的羧基团;Y代表可酯化或酰化的羧基团;n表示1或2,或其盐和包含这些化合物的细胞黏附
抑制剂的代理物被公开。这些化合物具有更强大和持久的抑制细胞黏附活性,因此可用作口服抗血栓药物。
