摘要:
L-ascorbic acid tablets which contain more than about 90 weight percent of L-ascorbic acid and have a satisfactory mechanical strength can be obtained by spray-coating L-ascorbic acid powder capable of passing through a 200-mesh screen, with a solution of a binder under constant agitation in fluidized-bed granulating apparatus, until the amount of the binder has reached about 2 to about 4 weight percent relative to L-ascorbic acid, and compressing the resultant granules mixed with a lubricant into tablets.
摘要:
The trifluoromethylketone derivatives (I) and pharmaceutically acceptable salts thereof have a human leukocyte elastase inhibiting activity and are useful as human leukocyte elastase inhibitors for treating or preventing degenerative diseases. The trifluoromethylketone derivatives (I) have the following formula: ##STR1## wherein R.sup.1 is C.sub.1-6 alkyl which has one or two substituents selected from carboxy, esterified carboxy and di-C.sub.1-6 alkylcarbamoyl; phenyl(C.sub.1-6) alkyl, the phenyl moiety of which may have halogen or nitro or amino substituents and the alkyl moiety of which may have carboxy or esterified carboxy substituents; halo-phenyl; morpholino; or morpholino(C.sub.1-6) alkyl,R.sup.2 and R.sup.3 are each C.sub.1-6 alkyl,X is -- or --NH--, andY is ##STR2## and pharmaceutically acceptable salts thereof.
摘要:
Compounds of the formula ##STR1## and its salts, wherein A is lower alkylene, and R is optionally acyl or lower alkoxy carbonyl substituted amino or optionally acyl substituted hydroxy. The compounds are useful as intermediates in making cephalosporin derivatives.
