Title: Production of glycoside, particularly steroidal gycoside
Inventor: KLEMKE RUDOLF ERICH
IPC: C07J17/00
Filed: 1992-07-22
Granted: 1999-06-15
Abstract: Novel glycosides, especially steroidal glycosides, and a novel method of their production, are provided. For the novel method of producing novel glycosides, hydroxysteryl compounds are glycosylated with tri-O-acyl glucal using molecular iodine as a reaction catalyst. In this method an alcohol or phenol, especially a hydroxy-steroid such as a water-insoluble cholesterol, is glycosylated, such that the glycosylation is performed in a single step. The resulting steryl pyranoside is by oxidation converted to the corresponding 7-ketosteryl di-O-acyl-pyranoside. The latter pyranoside is selectively reduced to provide the corresponding 7-(beta)-hydroxysteryl 2,3-dideoxy-(alpha)-D-erythro-hex-2-enopyranoside. The steroidal glycosides obtained in this way possess valuable pharmacological properties. In particular, the glycosides in vivo exhibit a selective cell-destructive activity on malignant cells which activity is substantially free of side effects on normal cells. The glycosides also possess a drive-enhancing (stimulating) activity and an anti-inflammatory (immunosuppressive or immunoregulatory) activity.

Abstract: The appts. (30) comprises essentially an anvil (32) and an opposed strap engaging member (80), with serrated faces (34, 112) through which the strap (U,L) passes. Anvil (32) has positioner that allows it to squeeze strap (U,L) against member (80) and plunger (92) at a first position, against plunger (92) only at a second position, and to disengage wholly at a third position. Strap engaging member (80) has a coaxial spring-loaded plunger (92) and is mounted on bearings (60) in cavity (54) of drive shaft (46), which itself is mounted on bearings (44) in bore (42) of support frame (40). The axis (58) of member (80) is offset (X) from the axis (48) of drive shaft (46), so rotation of the drive shaft confers an orbital motion to member (80). When the motion is applied to strap (U,L) clamped between anvil (32) and member (80), it creates friction between the strip faces and forms a friction weld conventionally. When anvil (32) is moved to the second position, the orbital motion is disengaged and smooth-faced plunger (92) maintains pressure on strap (U,L) while the weld cools.

Abstract: The invention relates to a process for treating oil deposits by the injection of a drilling fluid in admixture with a chemical solution, in an environment adjacent to the bore hole. With a view to increasing the final recovery factor, into the environment adjacent to the bore hole there is injected a unique system in a concentration of 3...4% by weight in relation to the water in the deposit, the solution comprising alkylbenzenesulphonic acid, sodium hydroxide, oxygenated water and phosphoric acid, which, within at least 3 days shall start a limited internal combustion with pressure and thermal gradient increase in the deposit layer, leading to the release of raw organic material and iron oxides with an increase of formation permeability.
