The compounds of the formula ##STR1## wherein G stands for an amidino group or an optionally cyclic amino group, these being respectively optionally substituted; D stands for a spacer having 2 to 6 atomic chain optionally bonded through a hetero-atom and/or a 5- to 6-membered ring (provided that the 5- to 6-membered ring is, depending on its bonding position, counted as 2 to 3 atomic chains); R.sup.1 stands for hydrogen, benzyl group or a lower alkyl group; R.sup.2 and R.sup.3 independently stand for a residual group formed by removing --CH(NH.sub.2)COOH from an .alpha.-amino acid, or R.sup.1 and R.sup.2 may form a 5- to 6-membered ring taken together with the adjacent N and C; X stands for hydrogen or an optionally substituted lower alkyl group; and Z stands for a group capable of forming an anion or a group convertible into an anion in a living body, or salts thereof and agents for inhibiting cell-adhesion, which are characterized by containing these compounds. The novel compounds and pharmaceutical agents are effective for prophylaxis and therapy of various diseases by controlling or inhibiting cell adhesion.
公式为##STR1##的化合物,其中G代表羧酰胺基团或可选择性取代的环氨基团;D代表具有2至6个原子链的间隔物,可通过杂原子和/或5至6个成员环(前提是5至6个成员环,根据其结合位置,被计算为2至3个原子链)进行选择性结合;R.sup.1代表氢、苄基或较低烷基;R.sup.2和R.sup.3分别代表通过去除α-氨基酸中的-CH(NH.sub.2)COOH形成的残基,或R.sup.1和R.sup.2可以与相邻的N和C一起形成5至6个成员环;X代表氢或可选择性取代的较低烷基;Z代表能够在活体内形成阴离子或可转化为阴离子的基团,或其盐和抑制细胞黏附的药剂,其特征在于包含这些化合物。这些新型化合物和药物剂对于通过控制或抑制细胞黏附预防和治疗各种疾病具有有效性。
