  • Publication number: 20120157371
    Abstract: The invention provides compositions of novel high penetration compositions (HPC) or high penetration prodrugs (HPP) of antimicrobials and antimicrobial-related compounds, which are capable of crossing biological barriers with high penetration efficiency. The HPCs/HPPs are capable of being converted to parent active drugs or drug metabolites after crossing the biological barrier and thus can render treatments for the conditions that the parent drugs or metabolites can. Additionally, the HPPs are capable of reaching areas that parent drugs may not be able to access or to render a sufficient concentration at the target areas and therefore render novel treatments. The HPCs/HPPs can be administered to a subject through various administration routes, e.g., locally delivered to an action site of a condition with a high concentration or systematically administered to a biological subject and enter the general circulation with a faster rate.

  • Patent number: 6051678
    Abstract: Copolymers containing N-vinyllactam derivatives protected at 3-position are provided and represented by the following formula. The copolymers are used as a photoresist material suitable for deep uv process so that high sensitivity and resolution can be obtained. In addition, ultrafine circuits can be formed and an exceptional improvement in PED stability can be accomplished by use of the photoresist.

  • Patent number: 5532232
    Abstract: Compounds of the formula ##STR1## wherein L, M, R, T and X are set forth in the description, as well as hydrates or solvates thereof, which inhibit thrombin-induced platelet aggregation and clotting of fibrinogen in plasma, are described. The compounds of formula I are prepared by amidination or, depending on whether L is NH or O, by amide formation or esterification.

  • Patent number: 4960881
    Abstract: The invention relates to carbonates of formula: ##STR1## in which X is a fluorine, chlorine or bromine atom and R.sup.1 is different from the ##STR2## group and represents: a substituted or non-substituted, saturated or unsaturated, aliphatic, araliphatic, primary, secondary, tertiary or cycloaliphatic radical. These .alpha.-chlorinated carbonates are prepared by the action of a compound of formula R.sup.1 OH on a chloroformate of formula: ##STR3## in a solvent medium in the presence of an acid scavenger which is added after the two preceding compounds. They are used to block the amine function of amino acids. The .alpha.-chlorinated carbonate and amino acid are reacted in a solvent medium at a temperature of -5.degree. to 100.degree. C. in the presence of an acid scavenger. Blocked amines are very useful in peptide synthesis.
