Title: Antracycline conjugates having a novel linker and method for the production
Inventor: GREENFIELD ROBORT S
IPC: C07H15/252
Filed: 1990-05-17
Granted: 1998-04-25
Abstract: The present invention relates to novel conjugates, methods for their production, pharmaceutical compositions and methods for delivering cytotoxic anthracyclines to a selected population of cells desired to be eliminated. The anthracycline conjugates comprise at least one anthracycline molecule linked to a ligand that is reactive with a cell population to be eliminated, the anthracycline having a keto group at the C-13 position, and being attached to the ligand via a linker arm and being bound to that linker arm via an acid-sensitive acylhydrazone bond at the 13-keto position of the anthracycline. The conjugates of the invention are therefore useful in antibody- or ligand-mediated drug delivery systems for the preferential killing of a selected cell population in the treatment of diseases such as cancers and other tumors, non-cytocidal viral or other pathogenic infections, and autoimmune disorders.

Abstract: The method for partially replacing catalysts in a reactor(A) in the mfg. process of PTA comprises the following processes of i) filling the reactor with water up to its upper portion, ii) inserting the upper end of a hose(B) having an intermediate valve(1) and a lower valve(2) into the reactor through an upper manhole(4), iii) setting the lower end of the hose to be lowered under the bottom of the reactor, iv) and refilling new catalyst n the reactor after partially discharging pref. one sixth of catalyst contained in the reactor out to a reservoir tank(C), in a manner of alternately opening and closing the intermediate valve as well as alternately closing and opening the lower valve.

Title: Waste water treatment method
Inventor: LEE MIN-CHOL
IPC: C02F1/70
Filed: 1993-09-08
Granted: 1996-09-04
Abstract: The acid wastes water without discharge is treated by adjusting pH to 9.0-10.0 by mixing wastes water and slaked lime, and removing sludge in wastes by agitating and settling wastes water, and reprecipitating and removing cohered deposit by anion polymer and alum, and filtrating floating matters, and treating filtrated water with EDR devices.

Title: Novel benzothiazole derivatives and process for preparing the same
Inventor: JUNG BON-YOUNG
IPC: A61K31/505
Filed: 1993-09-22
Granted: 1997-04-25
Abstract: The benzothiazole derivative of general formula and its enantiomer is prepared as follows: (1) A compound of general formula(VI) is replaced by a halogen and is reacted with alkyl or acylhalide under alkali condition to obtain a compound of general formula(VII). (2) After halogen-lithium replacement reaction of a compound(VII), a compound of general formula(VIII) is obtained by reacting with dimethyl oxalate. (3) And then an intermediate of general formula(i) is produced by reacting a compound of general formula(VIII) with methoxyl amine under basic condition or wittig reaction with phosphorous ylide. A benzothiazole is used for eliminating botanical germs or animal fungus. In the above formula, R1, R2 and R3 is independent hydrogen, halogen atom and like respectively. X is nitrogen or hydrocarbon.

Title: Manufacturing process of acetate/rayon conjugated yarn
Inventor: AHN SEUNG-SIK
IPC: D01F2/00
Filed: 1993-12-31
Granted: 1996-02-27
Abstract: The acetate/rayon conjugated yarn is produced by (a) spinning and winding an acetate yarn, and then supplying a viscose rayon yarn to the acetate yarn just before the interlacing nozzle, (b) conjugating the yarns at 350m/min speed or less to be 2.5˜3.0% cohesion amount of the oiling agent, and (c) interlacing the conjugated yarn at 1.8˜2.3kg/cm2 air pressure. The conjugated yarn has a good repulsive elasticity and interlacing strength, is free of a static electricity, and is useful as a raw material of spring and autumn wears.
