Abstract
This invention encompasses compounds of the formula: ##STR1## and the pharmaceutically acceptable non-toxic salts thereof wherein X and Y are the same or different and represent oxygen or H.sub.2 with the proviso that not both X and Y are H.sub.2 ; W represents phenyl, thienyl, or pyridyl, each of which may be unsubstituted or momo or disubstituted with organic or inorganic substituents; and R.sub.1, R.sub.2, R.sub.3, and R.sub.4 are variables representing organic and inorganic substituents. 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.
