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.
Disclosed are the ERK inhibitors of formula 1.0:
and the pharmaceutically acceptable salts and solvates thereof. Q is a piperidine or piperazine ring that can have a bridge or a fused ring. The piperidine ring can have a double bond in the ring. All other substituents are as defined herein. Also disclosed are methods of treating cancer using the compounds of formula 1.0.

3-(tert-Butyl)-4-hydroxyphenyl 2,4-dichlorobenzoate (1) was discovered in our in-house high throughput screening as a moderate FXR antagonist. To improve the potency and the stability of the hit 1, forty derivatives were synthesized and SAR was systematically explored. The results turn out that replacing the 2,4-dichlorophenyl with 2,6-dichloro-4-amidophenyl shows great improvement in potency, replacing the benzoate with benzamide shows improvement in stability and slight declining of potency and 3-(tert-butyl)-4-hydroxyphenyl unit is essential in obtaining the FXR antagonistic activity.
