  • Use of tricyclic derivatives of 1,4-dihydro-1,4-dioxo-1H-naphthalene, novel compounds obtained and their application in theraphy
    Patent number: 6262095
    Abstract: The invention concerns the therapeutic use of tricyclic salts and their pharmaceutically acceptable salts having the general formula: in which: A is either a sulfur atom, an oxygen atom, or an R3N radical where R3 is a hydrogen atom, a C1-C5 alkyl radical, or a substituted or unsubstituted aromatic ring, or a substituted or unsubstituted heteroaromatic ring. R1 is either a C1-C5 alkyl radical, or an R4NH radical where R4 is a hydrogen atom, a C1-C5 alkyl radical, or a substituted or unsubstituted aromatic ring, or a substituted or unsubstituted heteroaromatic ring, or an aromatic ring that may or may not be substituted by one or more acceptor or donor groups, or a heteroaromatic ring having one or more heteroatoms, which may or may not be substituted by acceptor or donor groups.

  • Mono-- or diketone tetracyclic derivatives and therapeutical uses thereof
    Patent number: 5981544
    Abstract: Invention concerning the therapeutic use of tetracyclic derivatives and their pharmaceutically acceptable salts having the following general formula: ##STR1## in which, independently of the other: X is a carbon or nitrogen atom,T is a carbon or nitrogen atom,L is an oxygen atom or ketone functional protective group,R.sub.1 is an atom of hydrogen, an atom of halogen, or a C.sub.1 to C.sub.5 alkyl radical,R.sub.2 is a hydrogen atom, a halogen atom, a nitro radical, or a C.sub.1 to C.sub.5 alkyl radical,n and m are equal to 0 or to 1, but not independently of the other, so that if n is equal to 1, then m is equal to 0, and if n is equal to 0, then m is equal to 1.
