    Abstract: A controlled release biocidal salt of a first component comprises a cation of a N?—(C1-C22) alkanoyl di-basic amino acid alkyl (C1-C22) ester cationic biocidal molecule and a second component comprising an anion of a monomeric anionic molecule having insignificant biocidal activity. The salt is characterized such that when the salt is exposed to an aqueous medium, the salt partially dissolves thereby releasing biocidal ions in an amount sufficient to exceed the MIC or MBC of a target bacteria being controlled, and further characterized as leaving a residual reservoir of undissolved salt capable of releasing more biocidal ions as the salt is consumed or otherwise removed from the environment encompassing the target bacteria. The preferred cationic biocidal molecule comprises N?-lauroyl-L-arginine ethyl ester (“LAE”).

  • Patent number: 5654452
    Abstract: Aromatic acid-derived lipophilic polyhalogenated compounds are provided for use as contrast agents in diagnostic imaging or as therapeutic agents. These compounds are particularly useful when incorporated into an oil-in-water emulsion for tissue-specific delivery to the liver. For hepatocyte-selective delivery, the emulsion is chylomicron remnant-like by being in a size range of 50 to 200 nm and having a composition simulating naturally-occuring chylomicron remnants.

  • Patent number: 5391812
    Abstract: Polyglycolate compounds are provided having the general structure: ##STR1## wherein n is an integer from 2 to about 10; R is C.sub.1-20 linear or branched alkyl, alkoxylated alkyl, cycloalkyl, aryl, alkylaryl, substituted aryl; R' and R" are independently H, C.sub.1-20 alkyl, aryl, C.sub.1-20 alkylaryl, substituted aryl, and NR.sub.3.sup..alpha.+, wherein R.sup..alpha. is C.sub.1-30 alkyl; and L is a leaving group displaceable in a peroxygen bleaching solution by perhydroxide anion. When this compound is combined with a source of peroxygen in aqueous solution, then a plurality of stain removing peracids are formed. Such peracids are formed substantially sequentially beginning with the carbonyl adjacent to the leaving group L. Thus, a first stain removing peracid having the structure ##STR2## will be formed in amounts approaching quantitative yield.
