Compounds of the formula ##STR1## wherein R.sub.1 and R.sub.2 are each C.sub.16-18 long-chain aliphatic acyl and are the same or different; and pharmacologically acceptable salts thereof are disclosed. These novel compounds are effective against 5-FU-resistant tumor cells, have low toxicity, and are not inactivated by nucleoside phosphorylase in vivo.
摘要:
A compound of the formula ##STR1## wherein A is adenine-9-yl and X is halogen, Preferably iodine, or a pharmaceutically acceptable salt thereof. It is a novel derivative of neplanocin A and has almost the same level of cytotoxic activity. However, it is not inactivated by the action of adenosine deaminase. It is produced by replacing a hydroxyl at position-6' in neplanocin A or 2', 3'-O-protected neplanocin A with halogen by use of a halogenating agent, and when hydroxyl at position-2' or -3' is protected, removing the protective group thereof.
摘要:
Novel nucleoside-phospholipid conjugates of the formula ##STR1## wherein R.sub.1 is C.sub.14-24 long chain aliphatic acyl or C.sub.1-24 aliphatic alkyl and N.sub.s is a nucleoside residue; and pharmacologically acceptable salts thereof are prepared in a one-step reaction by reacting the corresponding nucleoside and glycerophospholipid derivative in the presence of phospholipase D-P.

Novel nucleoside-phospholipid conjugates of the formula ##STR1## wherein R.sub.1 is C.sub.14-24 long chain aliphatic acyl or C.sub.1-24 aliphatic alkyl, R.sub.2 is C.sub.2-10 aliphatic acyl or C.sub.1-24 aliphatic alkyl and N.sub.s is a nucleoside residue; and pharmacologically acceptable salts thereof are prepared in a one-step reaction by reacting the corresponding nucleoside and glycerophospholipid derivative in the presence of phospholipase D-P.
摘要:
An information processing apparatus having a resume function which can maintain security even when a plurality of users use a common information processing apparatus. A work state at a power-off time is preserved together with a work state name including a user's ID in a different area in a plurality of preservation areas for the resume operation function on a main memory for each user. When a power source is turned on again, data in the preservation area corresponding to the user's ID is used to reproduce the work state of the user at the power-off time. A work state preservation file on a file server apparatus in a network has a resume function which does not need battery back-up. When this information processing apparatus is used, a work state at a power-off time can be independently preserved and reproduced for each of users, thereby realizing a resume function that is excellent in terms of security and utility.
摘要:
A virtual machine for operating, on a base machine, applications software for a target machine. The virtual machine includes first display control hardware for the base machine, second display control hardware for the target machine, a virtual machine monitor for emulating the operation of the target machine by utilizing the second display control hardware for displaying operation, and a selector for selecting one of the first display control hardware and the second display control hardware depending on whether the virtual machine monitor is operable in a target machine mode or a base machine mode. The OS of the base machine is utilized for the virtual machine without modification.
摘要:
An information processing apparatus having a resume function which can maintain the security even when a plurality of users commonly use the apparatus. A work state at a power-off time of the apparatus is preserved together with a work state name including a user's ID in a different area in a plurality of preservation areas for resume function on a main memory for each user. When a power source is again turned on, data in the preservation area corresponding to the user's ID is used to reproduce the work state of the user at the power-off time. The work preservation areas can be provided on a file server apparatus in a network not needing battery back-up. When the information processing apparatus is used, a work state at a power-off time can be independently preserved and reproduced for each user.
摘要:
Compounds represented by general formula I or salts thereof, wherein n is an integer of 2 or 3; R represents a straight-chain or branched saturated alkyl group having 4 or 4 carbon atoms, a cyclopentyl group, a cyclohexyl group or the like, Y represents a hydroxyl or amino group, A represents a hydrogen atom, a hydroxyl, methoxy, nitro group or the like, Q represents a hydrogen atom or a hydroxyl or methoxy group. They can be formulated to give pharmaceutical compositions that are effective as prophylactic or therapeutic agents for allergic diseases associated with IgE production inhibitors or IgE antibodies.
摘要:
A facsimile server system which can be utilized similarly to a stand-alone FAX. A remote FAX includes a scanner, a printer and a FAX communication unit. A client delivers document data to a FAX server, and makes a request for FAX transmission/printing. The FAX server expands the document data requested to be transmitted, into image data, and it transfers the image data to the appropriate remote FAX and gives a command for the FAX transmission/printing. When instructed to perform FAX transmission directly by a user, the remote FAX accepts the image of a handwritten document, and it subsequently delivers the image data of the document to the FAX server and makes a request for the FAX transmission. Besides, when the remote FAX has been commanded to scan image data or has received image data as FAX reception, it delivers the scanned image data or the received image data to the FAX server. Then, the FAX server accumulates the image data and offers them to the client in accordance with a retrieval process.
摘要:
An electrode for an electrolyte circulation-type cell stack secondary battery includes a pair of microchannels for supplying and exciting an electrolyte to or from an electrode member, and each of the microchannels is formed a first hindrance portion having a plurality of wall-shaped projections and a second hindrance portion integrally with a stepped portion in the electrode thickness direction and numerous small cylindrical projections arranged on the stepped portion in a staggered manner with respect to the flow direction of the electrolyte thereby making uniform the flow of the electrolyte on the surface of the electrode member, suppressing the formation of dendrites, making the current density uniform and improving the cell energy efficiency.
