Antimalarial drugs. 61. Synthesis and antimalarial effects of 4-[(7-chloro-4-quinolinyl)amino]-2-[(diethylamino)methyl]-6-alkylphenols and their N.omega.-oxides
摘要:
A series of 4-[(7-chloro-4-quinolinyl)amino]-2-[(diethylamino)methyl]-6-alkylphenols and their N omega-oxides were synthesized by the condensation of 4,7-dichloroquinoline and 4,7-dichloroquinoline N omega-oxide with appropriately substituted 4-amino-2-[(diethylamino)methyl]-6-alkylphenol dihydrochlorides. The latter precursors were prepared in a six-step synthesis starting from available 2-alkylphenols. Several of the title compounds display potent antimalarial activity in mice.
Compounds of the formula ##SPC1## Wherein A designates that the fused six-membered ring could be either unreduced, partially reduced or totally reduced and wherein R.sup.1 is --N(CH.sub.3).sub.2, --N(C.sub.2 H.sub.5).sub.2, ##EQU1## or --N(CH.sub.2 CH.sub.2 Cl).sub.2 and R.sup.2 is ##SPC2## And R is an acyl group with 1-5 carbon atoms, and pharmaceutically acceptable salts thereof; processes for their preparation; pharmaceutical preparations containing at least one of these compounds and the use thereof in the treatment of and protection against malaria infection.
