  • Patent number: 6399600
    Abstract: The invention relates to novel oxazinones designed to bind to the penicillin receptor, methods of synthesizing the compounds, and the use of the compounds as antibacterial agents. The compounds have the general formula (I) Preferably the compounds have a carboxyethyl or a substituted carboxymethyl substituent at the 2-position and a hydroxyl group at the 5-position and have a molecular shape suitable for binding to and reacting with the active site of a pencillin-recognizing enzyme. The compounds are synthesized by condensing a carboxyl-protected N-hydroxy amino acid with a 3-hydroxyprotected-4-bromobutanoic acid to form a a doubly protected N-hydroxy N-acylamino acid, which is cyclized with an organic base to yield a doubly protected 1,2-oxazin-3-one. The protecting groups are then removed to provide an antibacterial agent.

  • Patent number: 6380182
    Abstract: The invention relates to a method to inhibit bacteria from adhering to a submergible surface. The method contacts the submergible surface with an effective amount of at least one sulfamic acid or salt thereof to inhibit bacterial adhesion to the submergible surface. The invention also relates to a method for controlling biofouling of an aqueous system. This method adds an effective amount of at least one sulfamic acid or salt thereof to inhibit bacteria from adhering to a submerged surface within the aqueous system. This method effectively controls biofouling without substantially killing the fouling organisms. The sulfamic acid used in the method of the invention has the formula R1R2NS(O)2(OH). In this formula, R1 and R2 are independently a hydrogen, a C4-C20 alkyl group or a cyclohexyl group. However, R1 and R 2 are not both hydrogen.

  • Patent number: 5801023
    Abstract: This invention provides compounds of the following chemical formula or their pharmaceutically-acceptable salts: ##STR1## wherein R is hydrogen or chloro. Also, the present invention provides a process for the production of the compound of formula I, which comprises cultivating a microorganism having the identifying characteristics of Aspergillus fischeri var. thermomutatis ATCC 18618 or the like, and then isolating the compound of formula I from the fermentation broth. The pyrrolobenzoxazine compounds of formula I of this invention have broad antiparasitic activity, and thus are useful as antiparasitic agents, especially as anthelmintics.
