摘要:
A series of non-peptidergic antagonists of NPY have been synthesized and are comprised of phenyl derivatives of imidazolone compounds of Formula I. ##STR1## As antagonists of NPY-induced feeding behavior, these compounds and known analogs are expected to act as effective anorexiant agents in promoting weight loss and treating eating disorders.
摘要:
The present invention is concerned with a process for the manufacture of chiral succinic acid derivatives of formula (I) ##STR1## wherein R.sup.1 is (C.sub.1 -C.sub.6) alkyl or benzyl, and the novel intermediates used therein.
摘要:
The present invention relates to hydantoin derivatives of the formula I ##STR1## and which are intermediates for the preparation of pharmaceutical active compounds, their preparation and their use in the preparation of the active compounds.
摘要:
##STR1## Compounds of formula (I), wherein R 1 is an electronegative substituent such as nitro, halogeno or cyano group and R 2 is a group selected from (Ia) and (Ib), wherein R is hydrogen, or an alkyl, cycloalkyl, aralkyl or aryl group, wherein X 1 , X 2 , Y and Z are independently oxygen, sulfur of NR, wherein R may be as defined above and pharmaceutically acceptable esters and salts thereof are useful in the prevention or treatment of tissue damage induced by lipid peroxidation.
摘要:
Anticonvulsive compounds and compositions, of the formula ##STR1## in which X is a C.sub.1-4 -alkyl, trifluoromethyl, or halogen residue, Y is hydrogen or halogen, n is 0 or 1, and m is 0 or a cardinal number from 1 to 4, and its pharmacologically acceptable acid addition salts.
摘要:
The present invention provides labeled synthetic libraries of random oligomers and methods and apparatus for generating labeled synthetic oligomer libraries. Each member of such a library is labeled with a unique identifier tag that specifies the structure or sequence of the oligomer. In a preferred embodiment of the present invention the identifier tag is a microchip that is pre-encoded or encodable with information that is related back to a detector when the identifier tag is pulsed with electromagnetic radiation.
摘要:
The present invention consists in a method of preparing amino thiohydantoins either in isolation or as the C-terminals residue of a peptide. The method comprises reacting the amino acid or peptide with an acylating agent and thiocyanate or isothiocyanates in the presence of a strong acid. The present invention also relates to an improved method for C-terminal sequencing of peptides which routinely analyses all of the common amino acids of peptides. The invention involves the use of a strong, volatile, anhydrous organic or mineral acid to cleave the terminal amino acid thiohydantoin.
摘要:
The invention encompasses compounds of the formula: ##STR1## and the pharmaceutically acceptable salts thereof wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4, and X are variables; and W is phenyl optionally substituted with straight or branched chain lower alkyl having 1-6 carbon atoms or straight or branched chain lower alkoxy having 1-6 carbon atoms. These compounds are highly selective agonists, antagonists or inverse agonists for GABAa brain receptors or prodrugs thereof and are useful in the diagnosis and treatment of anxiety, sleep, and seizure disorders, overdose with benzodiazepine drugs, and enhancement of memory.
摘要:
The invention provides hydroxamic acid derivatives of the general formula ##STR1## wherein R.sup.1 represents cyclopropyl, cyclobutyl, cyclopentyl or cyclohexyl; R.sup.2 represents a saturated 5- to 8-membered monocyclic or bridged N-heterocyclic ring, which N-heterocyclic ring is attached via the N atom and when it is monocyclic, optionally contains NR.sup.4, O, S, SO or SO.sub.2 as a ring member and/or is optionally substituted on one or more C atoms by hydroxy, lower alkyl, lower alkoxy, oxo, ketalized oxo, amino, mono(lower alkyl)amino, di(lower alkyl)amino, carboxy, lower alkoxycarbonyl, hydroxy-methyl, lower alkoxymethyl, carbamoyl, mono(lower alkyl)-carbamoyl, di(lower alkyl)carbamoyl or hydroxy-imino; R.sup.3 represents a 5- or 6-membered N-heterocyclic ring which (a) is attached via the N atom, (b) optionally contains N, O and/or S, SO or SO.sub.2 as an additional ring member, (c) is substituted by oxo on one or both C atoms adjacent to the linking N atom and (d) is optionally benz-fused or optionally substituted on one or more other C atoms by lower alkyl or oxo and/or on any additional N atom(s) by lower alkyl or aryl; R.sup.4 represents hydrogen, lower alkyl, aryl, aralkyl or a protecting group; m stands for 1 or 2 and n stands for 1-4, pharmaceutically acceptable salts thereof, intermediates used in the manufacture thereof, and methods of use therefor. Compounds of formula I are collagenase inhibitors useful in the control or prevention of degenerative joint diseases such as rheumatoid arthritis and osteoarthritis or in the treatment of invasive tumours, atherosclerosis or multiple sclerosis.
