Abstract
The present invention provides new chemically modified 4-dedimethylaminotetracycline compounds that can be substituted with aryl, alkenyl, or alkynyl groups. The 7, 8, and/or 9 positions and methods for preparing such compounds. Other tetracycline compounds include the 4-dedimethylaminotetracycline derivatives with an oxime group, NH-Alkyl, or N—NH-Alkyl group substituted at the C4 position as well as C2 Mannich derivatives. The present invention also provides a method of treating a mammal suffering from conditions or diseases by administering to the mammal an effective amount of the new chemically modified tetracycline compounds.
Claims
exact text as granted — not AI-modified1 . A tetracycline compound of the formulae:
wherein:
R7 is selected from the group consisting of hydrogen, amino, nitro, mono(lower alkyl)amino, halogen, di(lower alkyl)amino, ethoxythiocarbonylthio, azido, acylamino, diazonium, cyano, and hydroxyl;
R6-a is selected from the group consisting of hydrogen and methyl;
R6 and R5 are selected from the group consisting of hydrogen and hydroxyl;
R8 is selected from the group consisting of hydrogen and halogen;
R9 is selected from the group consisting of hydrogen, amino, azido, nitro, acylamino, hydroxy, ethoxythiocarbonylthio, mono(lower alkyl)amino, halogen, diazonium, di(lower alkyl)amino and RCH(NH 2 )CO;
R is hydrogen or lower alkyl; and
pharmaceutically acceptable and unacceptable salts thereof; with the following provisos:
when either R7 and R9 are hydrogen then R8 must be halogen; and
when R6-a, R6, R5 and R9 are all hydrogen and R7 is hydrogen, amino, nitro, halogen, dimethylamino or diethylamino, then R8 must be halogen; and
when R6-a is methyl, R6 and R9 are both hydrogen, R5 is hydroxyl, and R7 is hydrogen, amino, nitro, halogen or diethylamino, then R8 is halogen; and
when R6-a is methyl, R6 is hydroxyl, R5, R7 and R9 are all hydrogen, then R8 must be halogen; and
when R6-a, R6 and R5 are all hydrogen, R9 is methylamino and R7 is dimethylamino, then R8 must be halogen; and
when R6-a is methyl, R6 is hydrogen, R5 is hydroxyl, R9 is methylamino and R7 is dimethylamino, then R8 must be halogen; and
when R6-a is methyl, R6, R5 and R9 are all hydrogen and R7 is cyano, then R8 must be halogen.
2 . A tetracycline compound of the formulae:

R is hydrogen or lower alkyl; and
pharmaceutically acceptable and unacceptable salts thereof, with the following provisos:
when R4 is NOH, N—NH-alkyl or NH-alkyl and R7, R6-a, R6, R5, and R9 are all hydrogen, then R8 must be halogen; and
when R4 is NOH, R6-a is methyl, R6 is hydrogen or hydroxyl, R7 is halogen, R5 and R9 are both hydrogen, then R8 must be halogen; and
when R4 is N—NH-alkyl, R6-a is methyl, R6 is hydroxyl and R7, R5, R9 are all hydrogen, then R8 must be halogen; and
when R4 is NH-alkyl, R6-a, R6, R5 and R9 are all hydrogen, R7 is hydrogen, amino, mono(lower alkyl)amino, halogen, di(lower alkyl)amino or hydroxyl, then R8 must be halogen; and
when R4 is NH-alkyl, R6-a is methyl, R6 and R9 are both hydrogen, R5 is hydroxyl, and R7 is mono(lower alkyl)amino or di(lower alkyl)amino, then R8 must be halogen; and
when R4 is NH-alkyl, R6-a is methyl, R6 is hydroxy or hydrogen and R7, R5, and R9 are all be hydrogen, then R8 must be halogen.
