摘要:
The invention relates to novel substituted 2,3-dihydro-5-(3-oxo-2-cyclohexen-1-yl)-2-benzofurancarboxylic acids, their derivatives and their salts. The compounds are useful for the treatment and prevention of injury to the brain and of edema due to head trauma, stroke (particularly ischemic), arrested breathing, cardiac arrest, Reye's syndrome, cerebral thrombosis, cerebral embolism, cerebral hemorrhage, cerebral tumors, encephalomyelitis, spinal cord injury, hydrocephalus, post-operative brain injury trauma, edema due to cerebral infections and various brain concussions.
摘要:
The invention relates to novel substituted-3-(2,3-dihydro-1H-inden-5-yl)-4-hydroxy-1H-pyrrole-2,5-diones, their analogs and their salts. These compounds are synthesized by methods selected from a number of synthetic routes depending on the particular structure, choice of intermediate or preferred reaction sequence. The compounds are useful for the treatment and prevention of injury to the brain and of edema due to head trauma, stroke (particularly ischemic), arrested breathing, cardiac arrest, Reye's syndrome, cerebral thrombosis, cerebral embolism, cerebral hemorrhage, cerebral tumors, encephalomyelitis, spinal cord injury, hydrocephalus, post-operative brain injury trauma, edema due to cerebral infections and various brain concussions.
摘要:
The invention relates to novel [(2,3,9,9a-tetrahydro-3-oxo-9a-substituted-1H-fluoren-yl)oxy]ethanimidamides and [(2,3,9,9a-tetrahydro-3-oxo-9a-substituted-1H-fluoren-7-yl)oxy]ethanimidic acid hydrazides, their derivatives and their salts. The compounds are useful for the treatment and prevention of injury to the brain and of edema due to head trauma, stroke (particularly ischemic), arrested breathing, cardiac arrest, Reye's syndrome, cerebral thrombosis, cerebral embolism, cerebral hemorrhage, cerebral tumors, encephalomyelitis, spinal cord injury, hydrocephalus, post-operative brain injury trauma, edema due to cerebral infections, various brain concussions and elevated intracranial pressure.

摘要:
1-Oxo-2,2-disubstituted-5-indanyloxy(or thio)alkanoic acids and their salt, ester, anhydride, amide and 5-tetrazolyl derivatives are disclosed. The products display a dual pharmaceutical utility in that they exhibit diuretic, saluretic and uricosuric activity. The acid products are prepared by treating a 2,2-disubstituted-5-hydroxy(or mercapto)-1-indanone with an haloalkanoic acid or ester thereof and, if the ester is employed, hydrolyzing the ester.

[1,3-Dioxo-2-substituted and 2,2-disubstituted-indanyloxy(or thio)]alkanoic acids and their salts, esters and amides are disclosed. The products display a dual pharmaceutical utility in that they exhibit diuretic, saluretic and uricosuric activity. The acid products are prepared by treating a (2,2-di or 2-)substituted-6-hydroxy-(or mercapto)-1,3-indanedione with a haloalkanoic acid or ester thereof and if the ester is employed hydrolyzing the ester.
