Abstract:
Manufacturing method of tetrazolylimidazoles was described. Tetrazoles, I, II (A = CH2, bond CHMe, CMe2, CH2CH2 : R1 = H, alky1, aralky1, alky1 group substituted by hetero aromatic ring; R2 = R3 = H, alkoxy or haloalky1 group, alky1 group: R4 = alky1, ally1, aralky1 group) were obtained by treating the cyanides(III) with NaN3. I, II had analgesic and uricosuric properties.
Abstract:
Title compds. [I; R1 = H, C1-2 alkyl, Ph, tolly1; R2-R5 = H, C1-2 alkyl; R6 = H, C1-3 substituent with O-position-condensed benzene or C1-3 alkoxy or halo-substituted alkyl having halo, NO2 or OH; A = single bond or C6H5-CH; Q = single bond or alkylene group of formula -CnH2n-(n = 2-6); X = O, S; Z = N or -CH having anti-coagulation or anti-serotonin activity were prepd. by eliminating R7(that is OH) in compds. II or by reacting compds. III with halogen compds. IV(3-isocyanato- or 3-isocyanato-alkano carboxylic acid; Hal = halo) or dihalogen compds. (IVa).
Abstract:
Compound having the formula (FORMULA) or its salts of addition of acids physiologically acceptable and process for its preparation, wherein is reacted: a) N-benzylpiperazine and 5-methoxy-benzofurane-2-carboxylic acid, a1) at a higher temperature and without using a condensing agent or a2) at a temperature of at least 15` C in presence of appropriate condensing agents, b) N-benzylpiperazine with an activated sub-product of 5-methoxybenzofurane-2-carboxylic acid or c) N-(5-methoxy-2-benzofuroyl)-piperazine with a benzyl halide, an alkyl-sulfonate of benzyl or an aryl-sulfonate of benzyl. Medicine, containing the above compound.
Abstract:
Compounds of general formula are disclosed wherein appropriate substituents for R1, R2 to R5, R6, A, Q, X, and Z are defined for these novel hexahydropyrimidines. Procedures for the preparation of these compounds are also given. Because of the highly effective serotonin antagonistic activity in combination with a strong inhibiting effect on thrombocyte aggregation and good compatibility these compounds are effective in treating migraine. Additionally, the compounds also exhibit an anti-histamine activity, cause an increase in erythrocyte fluidity, a psychotropic activity, a weak bradykinin antagonism and hypotensive effects.
