Abstract

This invention is directed to analogs of 5-(tetradecyloxy)-2-furancarboxylic acid (TOFA) and their use in the treatment of dermatological disorders or conditions characterized by sebaceous gland hyperactivity, such as acne and oily skin, and other dermatological disorders and conditions. This invention is also directed to pharmaceutical compositions comprising analogs of TOFA and a pharmaceutically acceptable excipient for dermatological or oral administration. Formula (I)

Claims (69)

1. A compound of formula (I):

wherein:

R 1 is —O—R 2 ; and

R 2 is haloalkyl or aryl optionally substituted with —COOH,

as a single stereoisomer or as a mixture thereof;

or a pharmaceutically acceptable salt thereof.

2. The compound of claim 1 selected from:

2,2,2-trifluoroethyl 5-(tetradecyloxy)furan-2-carboxylate;

2,2,2-trichloroethyl 5-(tetradecyloxy)furan-2-carboxylate;

2-bromoethyl 5-(tetradecyloxy)furan-2-carboxylate; and

2-(5-(tetradecyloxy)furan-2-carbonyloxy)benzoic acid.

3. A compound of formula (I):

wherein:

R 1 is —O—R 3 —C(O)N(R 5 )R 6 ;

R 3 is an alkylene chain; and

R 4 is alkyl, aryl, aralkyl, heteroaryl or heteroarylalkyl;

R 5 is hydrogen, alkyl, cycloalkyl, aryl or aralkyl; and

R 6 is alkyl, cycloalkyl, aralkyl or —R 3 —C(O)OR 4 ;

or R 5 and R 6 , together with the nitrogen to which they are both attached, form an N-heterocyclyl or N-heteroaryl, each of which being optionally substituted with cycloalkyl, aryl or —C(O)OR 4 .

4. The compound of claim 3 selected from:

2-(benzyl(methyl)amino)-2-oxoethyl 5-(tetradecyloxy)furan-2-carboxylate;

tert-butyl 4-(2-(5-tetradecyloxy)furan-2-carbonyloxy)acetyl)piperazine-1-carboxylate;

2-(dicyclohexylamino)-2-oxoethyl 5-(tetradecyloxy)furan-2-carboxylate;

2-(4-cyclohexylpiperazin-1-yl)-2-oxoethyl 5-(tetradecyloxy)furan-2-carboxylate;
