摘要:
A therapeutic and prophylactic agent for peptic ulcers which contains as an active ingredient a compound of the general formula (I): wherein R, represents hydrogen or =0; R 2 represents hydrogen or-OR 5 ; R 3 represents hydrogen or-OR 6 ; R 4 represents -OR 7 in the case of the absence of double bond, R 5 , R 6 and R 7 each represents hydrogen or an organic residue; X represents group (A): or group (B): wherein R 8 represents alkyl, and R 9 and R 10 each represents hydrogen or an organic residue; with the proviso that when X represents group (A), then R, and R 3 both represent hydrogen, R 2 represents -OR 5 , R 4 represents -OR 7 and the bond between the carbon atom to which X is attached and the carbon atom to which R 4 is attached is a single bond, and when X represents group (B), then R 1 represents =0, R 2 and R 4 both represent hydrogen, R 3 represents-OR 6 and the bond between the carbon atom to which X is attached and the carbon atom to which R 4 is attached is a double bond, or a pharmaceutically acceptable salt thereof, or a compound of the general formula (II): wherein R 11 represents hydrogen or an organic residue, and R 12 , R 13 and R 14 each represents an organic residue, or a pharmaceutically acceptable salt thereof. The compounds of the general formulae (I) and (II) can be derived from compounds contained in a hot water extract of cinnamon.
摘要:
A fibrinolytic activity enhancer for single-chain pro-urokinase comprising plasminogen as an active ingredient is disclosed. The fibrinolytic activity enhancer of the present invention enhances the fibrinolytic activity of single-chain pro-urokinase without causing systemic fibrinolysis. Thus, it is highly useful in the treatment of thrombosis and obstructive diseases.
摘要:
The invention relates to a method of heat-treating heat-labile plasma proteins for virus inactivation comprising heating a virus-contaminated plasma protein in a dry state and in the presence of both an acidic amino acid and a basic amino acid until virus inactivation is complete.
摘要:
Heat treatment of an aqueous solution or a fraction containing blood coagulation factor VIII to inactivate hepatitis viruses is carried out in the presence of a stabilizer selected from sugar-alcohols or disaccharides in a concentration of at least 1.5 g per ml of the acqueous solution or fraction.
摘要:
A method for purifying factor VIII complex comprising: (A) adsorbing an impure extract containing factor VIII complex on a water-insoluble carrier, and (B) recovering factor VIII complex in the unadsorbed fractions, wherein said water-insoluble carrier contains as a ligand a group represented by the formula (I) or (II): (CH₂) n -NH₂ (I) or (CH₂) n -CHO (II) wherein n is an integer of from 3 to 10.

摘要:
Human blood coagulation factor VIII which may have hepatitis virus activity can be virus-inactivated with keeping at a minimum the damage of the factor VIII by heating its aqueous solution at 50 to 80°C for 3 to 15 hours in the presence of 10% (WN) or more of at least one principal stabilizer of neutral amino acids, monosaccharides, oligosaccharides, and sugar alcohols and 10% (WN) or more of at least one auxiliary stabilizer of salts of hydrocarbon and hydroxyhydrocarbon carboxylic acids having 3 to 10 carbon atoms.
摘要:
Human blood coagulation factor VIII which may have hepatitis virus activity can be virus-inactivated with keeping at a minimum the damage of the factor VIII by heating its aqueous solution at 50 DEG to 80 DEG C. for 3 to 15 hours in the presence of 10% (W/V) or more of at least one principal stabilizer of neutral amino acids, monosaccharides, oligosaccharides, and sugar alcohols and 10% (W/V) or more of at least one auxiliary stabilizer of salts of hydrocarbon and hydroxyhydrocarbon carboxylic acids having 3 to 10 carbon atoms.
