    Abstract: PROBLEM TO BE SOLVED: To provide a method useful for treatment and prevention of diseases accompanying excess cell adhesion derived by selectin receptor by using a polymer of acryclic acid or methacrylic acid. SOLUTION: Polyacrylic acids and polymers of methacrylic acid or their salts, preferably polyacrylic acids having molecular weight of 900-63,000g/mol, are effective for treatment and prevention of diseases relating to selectin receptor-induced excess cell adhesion at tissues affected with a disease, particularly diseases of cardiac and vascular system or rheumatic diseases. This medicine is possible to administrate intravenously, orally or nonorally, or as pieces of transplantation and through rectum. The polyacrylic acids and polymethacrylic acids with high molecular weights are extremely strong and specific p-selectin antagonists.

    Abstract: Use of N-substituted pyrrolidone, imidazolidinone, oxazolidinone or thiazolidinone derivatives of formula (I), in all stereoisomer or mixture forms, or their salts is for inhibiting the adhesion and/or migration of leukocytes or inhibiting VLA-4 receptors is new. W = R1-A-CR13 or R1A-CH=C; Y = CO, CS or CH2; Z = O, S or CH2 etc.; A = 1-6C alkylene, 3-12C cycloalkylene, (1-6C), phenylene-(1-6C)alkyl, or the divalent residue of a 5- or 6-membered ring containing 1 or 2 N (optionally mono- or disubstituted) etc.; B = 1-6C alkylene (optionally substituted), 2-6C alkenylene, phenylene, phenylene-(1-3C) alkyl or (1-3C) alkylene-phenyl; D = CR2R3.

    Abstract: Imidazole derivs. of formula (I) and their salts are new. R1 = 1-6C alkyl. R2, R3 = independently H, F, Cl, Br, I or 1-3C alkyl. X = OH or -NR4R5. R4 = H or 1-7(1-4)C alkyl, opt. substd. by CN, NH2 or CO2H. R5 = 1-8 (1-5)C alkyl, opt. interrupted by phenyl and opt. substd. by not less than 1 OH, 1-3C alkoxy, (un)substd. phenyl, CO2H, CO2-(1-3C alkyl), -CONH2, CN, 2-5C alkynyl, NH2, NHR6, N(R6)2, N+(R6)3, NH-CO-(1-6C alkyl), a gp. of formula (i), a monocyclic 5-7 membered (un)saturated opt. substd. heterocycle with one N heteroatom, and opt. an extra N, O or S heteroatom, where the S atom can be oxidised to SO or SO2. Alternatively, R4 and R5 together form a 5-7 membered opt. substd. heterocycle which may contain, in addn. to the amide N atom, a further N, O or S heteroatom. The heterocycle is not morpholine. R6 = independently 1-4C alkyl, 2-6C alkoxyalkyl or phenyl-(1-3C alkyl). N-(2-morpholinoethyl)-1-methyl -2-imidazolsulphonic acid amide and N-(2-morpholinopropyl) -1-methyl-4-imidazolsulphonic acid amide are specifically claimed. Also claimed.are methods for preparing (I), e.g. by sulphonation of the corresponding mono-, di- or trisubstituted imidazole cpd.
