    摘要: The present invention is directed to a pyrimidine derivative of the following formula (1) or a salt of the derivative: [wherein R1 represents a lower alkyl group; each of R2 and R3 represents H, alkyl, or alkoxy; each of R4 and R5 represents H or alkyl; R6 represents alkyl, —OR7, or —NR8R9; and n is a number between 0 and 3 inclusive (wherein each of R7, R8, and R9 represents H, alkyl, aryl, aralkyl, amino, a heterocyclic ring, etc.)], as well as to a medicine containing the derivative or salt as the active ingredient. The present compounds exhibit strong binding inhibitory activity against endothelin having potent vasoconstrictive effect and cell proliferation effect. Therefore, the compounds are effective as remedies for various diseases including circulatory diseases.

    摘要: Thrombin-binding substances are obtained by fractionating human urine by ion-exchange chromatography, affinity chromatography using a thrombin-bound carrier, immune adsorption column chromatography, gel filtration, and/or molecular-weight fractionation. One of the substances has a molecular weight of 46,500.+-.6,000 in reduced condition and 39,000.+-.10,000 in unreduced condition by SDS PAGE and an isoelectric point at pH 5.0-5.3, while the other has a molecular weight of 40,000.+-.8,000 in reduced condition and 31,000.+-.10,000 in unreduced condition by SDS PAGE and an isoelectric point at pH 4.9-5.7. They have strong affinity to thrombin. They are capable of promoting the thrombin catalyzed activation of protein C and prolong clotting time. They are stable to denaturing agents (urea and sodium dodecylsulfate).
