Abstract: The present invention provides new thrombin inhibiting bisamidines derivatives, their pharmaceutically acceptable salts and hydrates, methods for their preparation, pharmaceutical composition, a process for their preparation, and use of the compounds in treatment of thrombosis, ischemia and stroke.

Abstract: This invention relates to elsamicin A derivatives wherein the 2"-amino group is selectively modified by acylation or alkylation, a process for producing said elsamicin A derivatives, an antitumor composition containing the same as the active ingredient, and a method for therapy using said compositions.

Abstract: This invention relates to novel elsamicin A derivatives having an alkylidene group on the 3' and 4'-OH group or a tetrahydropyranyl group on the 4'-OH group, a process for producing said elsamicin A derivatives, antitumor composition containing the same as the active ingredient, and a method for therapy using said compositions.

Abstract: This invention relates to the use of tocotrienol, gamma-tocotrienol and delta-tocotrienol in reducing hypercholesterolemia, hyperlipidemia and thromboembolic disorders in mammals. [The isolation of these tocotrienols from natural sources and their chemical synthesis is disclosed.] The chemical synthesis of these tocotrienols is disclosed. The present invention also relates to prodrugs and pharmaceutical compositions of gamma-tocotrienol, delta-tocotrienol and tocotrienol and uses thereof.

Abstract: A novel series of 1,3-dihydro-2H-imidazo[4,5-b]quinolin-2-ones having enhanced water solubility bioavailability and metabolic stability is disclosed in the Formula I ##STR1## wherein R.sup.1 is H, or C.sub.1 -C.sub.4 lower alkyl;R.sup.2 is H, (CH.sub.2).sub.m R.sup.3 ; benzoxazol-2yl, or benzothiazol2-yl;R.sup.3 is C.sub.1 -C.sub.8 alkyl, C.sub.4 -C.sub.8 cycloalkyl, or substituted or unsubstituted phenyl, wherein the substituents are halogen, alkoxy or trifluoromethyl;m is an integer of 1-3; andn is an integer of 1-5;or pharmaceutically acceptable salt thereof.The compounds are useful as inhibitors of ADP-induced blood platelet aggregation in human platelet-rich plasma.

Abstract: The present invention concerns nucleotide analogs and their compositions and use. In particular it relates to novel (phosphonomethoxy) methoxy purine/pyrimidine derivatives.

Abstract: The invention relates to novel farnesylated tetrahydro-naphthalenols, that inhibit HMGR activity which results in a decrease in serum total cholesterol, a decrease in LDL cholesterol levels, and inhibition of LDL oxidation. The farnesylated tetrahydro-naphthalenols of the present invention are thus useful for cholesterol/lipid lowering in cases of hypercholesterolemia, hyperlipidemia, and atherosclerosis.

Abstract: A novel series of oxazole derivatives is disclosed in the Formula I ##STR1## wherein Y and Z are independently hydrogen or together form a bond;X is CN, CO.sub.2 R.sup.1 or CO.NR.sup.2 R.sup.3 ;R and R.sup.1 are independently or together H, Na, or C.sub.1 -C.sub.5 lower alkyl;R.sup.2 and R.sup.3 are independently or together H, or C.sub.1 -C.sub.5 lower alkyl;or alkali metal salt thereof.The compounds are useful as inhibitors of ADP-induced blood platelet aggregation in human platelet-rich plasma.
