摘要:
This invention relates to the new process for preparing the 1R-cis isomer of carbovir, (1R-cis)-amino-1,9-dihydro-9-[4-(hydroxymethyl)-2-cyclopenten-1-yl]-6H-purin-6-one, an antiviral agent and intermediates of the formula (Vlb) use in that process ##STR1## wherein X is chloro, bromo or iodo and R is (C.sub.1-6) alkyl.
摘要:
This invention relates to new process for preparing certain optically active purine substituted cyclopentene derivatives and novel intermediates used in this process. In particular, the invention concerns the synthesis of the 1R-cis isomer of carbovir, (1R-cis)-amino-1,9-dihydro-9-[4-(hydroxymethyl)-2-cyclopenten-1-yl]-6H-purin-6-one, an antiviral agent, and certain intermediates.
摘要:
The present invention provides novel conformationally-defined macrocyclic compounds that have been demonstrated to be selective agonists of the ghrelin receptor (growth hormone secretagogue receptor, GHS-R1a and subtypes, isoforms and variants thereof). Such compounds are useful as medicaments for treatment and prevention of a range of medical conditions characterized by disturbed gastrointestinal motility including, but not limited to, post-surgical gastroparesis and post-operative ileus in combination with opioid-induced bowel dysfunction. These agents are effective for multiple disorders at dose levels equivalent to those required to treat a single disorder.
摘要:
The present invention provides novel conformationally-defined macrocyclic compounds that have been demonstrated to be selective modulators of the ghrelin receptor (growth hormone secretagogue receptor, GHS-R1a and subtypes, isoforms and variants thereof). Methods of synthesizing the novel compounds are also described herein. These compounds are useful as agonists of the ghrelin receptor and as medicaments for treatment and prevention of a range of medical conditions including, but not limited to, metabolic and/or endocrine disorders, gastrointestinal disorders, cardiovascular disorders, obesity and obesity-associated disorders, central nervous system disorders, genetic disorders, hyperproliferative disorders and inflammatory disorders.
摘要:
A system for providing data related to discounted services available near a given location. The system includes a memory storing compressed service data representative of a plurality of services in various locations categorized by type of service and compressed coupon data representative of discounts available for the services. The system also includes a book of coupons corresponding to the discounted services wherein the coupon data includes identifying numbers which identify locations of coupons within the coupon book corresponding to the discounts available for the services. A data entry circuit receives and compresses input data identifying a desired category of services and the given location and a microprocessor, receiving and responsive to the compressed input data, selectively retrieves the service data and coupon data from the memory. The retrieved service data represents one or more selected services in the desired category near the given location and the retrieved coupon data represents the discounts available for the selected services including the identifying numbers of the coupons. The microprocessor then expands the retrieved service data and coupon data into a user-readable form and a display displays the expanded retrieved service data and coupon data.

摘要:
The present invention is directed to novel macrocyclic compounds of formula (I) and their pharmaceutically acceptable salts, hydrates or solvates: wherein R1, R2, R3, R4, R5, R6, n1, m, p Z1, Z2, and Z3 are as describe in the specification. The invention also relates to compounds of formula (I) which are antagonists of the motilin receptor and are useful in the treatment of disorders associated with this receptor and with or with motility dysfunction.
摘要:
A data processing device for providing data related to the categories of services available at locations along a highway in response to operator input is disclosed. The device includes a memory, a keyboard for entering input data identifying a desired service and an origin position into the memory. The input data is compressed before it is stored in the memory. The memory stores predetermined data in a compressed form related to the categories of services available at locations along the highway. The device also includes a microprocessor for retrieving from the memory the predetermined data which is a function of the input data. The microprocessor expands the retrieved compressed data into an operator readable form and provides the expanded data to a display for displaying the expanded retrieved data such as restaurants, gas stations, motels, or other services along the highway.
