More particularly, new water-soluble triazole antifungal compounds are provided having the general formulawherein A is the non-hydroxy portion of a triazole antifungal compound of the type containing a secondary or tertiary hydroxyl group and R and R1 are as defined in the specification.
Abstract:
7-(D-( Alpha -Amino- Alpha -phenyl-, 2-thienyl- and 3thienylacetamido)-3-(3-methyl-1,2,5-oxadiazol-4yl)carbonylthiomethyl-3 -cephem-4-carboxylic acids and their pharmaceutically acceptable salts are valuable as antibacterial agents, as nutritional supplements in animal feeds, as agents for the treatment of mastitis in cattle and as therapeutic agents in poultry and animals, including man. The compounds are especially useful in the treatment, particularly by oral administration, of infectious diseases caused by many Gram-positive and Gramnegative bacteria. Also included within the invention are easily cleavable esters of the abovementioned acids and pharmaceutically acceptable acid addition salts of said esters.

Abstract:
3,14,17-Substituted-6,7-Tetramethylenemorphinans have been found to possess potent narcotic agonist and/or antagonist activity. In particular, the compounds l-17-cyclopropylmethyl-3,14 Alpha (and14 Beta )-dihydroxy-6,7-tetramethylenemorphinan have been found to possess potent narcotic antagonist activity. These compounds are prepared by total synthesis and are not derived from opium alkaloids.
Abstract:
A hair dressing composition comprising a hair substantive quaternary resin to impart hair-holding properties to hair when supplied, and a grooming agent; the grooming agent preferably being incompatible with the quaternary resin.
Abstract:
Appropriately substituted 11H-pyrimido(4,5-b)(1,4)benzodiazepines have shown biological activity, e.g., antihypoxic, hypothermic, antipyretic and anti-inflammatory. An example of a potent anti-hypoxic agent is 5,6-dihydro-11-methyl11H-pyrimido(4,5-b)(1,4)-benzodiazepine.
Abstract:
A safety closure-bottle assembly comprising a snap-on closure and bottle in which the closure is provided with a tab and the bottle neck with a notched flange which registers with said tab.
Abstract:
Derivatives of neomycin B and C have been prepared which possess substantially improved antibacterial activity. An example of such an agent is 1-(L-(-)- gamma -amino- Alpha -hydroxybutyryl)neomycin B (IVa, BB-K77).
