<p>Compounds of formula (I) are CRTH2 antagonists, useful in the treatment of, for example, asthma, chronic obstructive pulmonary disease, rhinitis, allergic airway syndrome, and allergic rhinobronchitis. Formula (I) wherein R<SUB>1</SUB>, R<SUB>2</SUB>. R<SUB>3</SUB> and R<SUB>4</SUB> each independently are hydrogen, C<SUB>1</SUB>-C<SUB>6</SUB>alkyl, fully or partially fluorinated C<SUB>1</SUB>-C<SUB>6</SUB>alkyl, halo, -S(O)<SUB>n</SUB>R<SUB>10,</SUB> -SO<SUB>2</SUB>N(R<SUB>10</SUB>)<SUB>2,</SUB> -N(R<SUB>10</SUB>)<SUB>2,</SUB> -C(O)N(R<SUB>10</SUB>)<SUB>2,</SUB> -NR<SUB>10</SUB>C(O)R<SUB>9,</SUB> -CO<SUB>2</SUB>R<SUB>10</SUB>, -C(O)R<SUB>9</SUB>, -NO<SUB>2, </SUB>-CN or -OR<SUB>11</SUB>; wherein each R<SUB>9</SUB> is independently C<SUB>1</SUB>-C<SUB>6</SUB>alkyl, aryl, heteroaryl; R<SUB>10</SUB> is independently hydrogen, C<SUB>1</SUB>-C<SUB>6</SUB>alkyl, aryl, or heteroaryl; R<SUB>11</SUB> is hydrogen, C<SUB>1</SUB>-C<SUB>6</SUB>alkyl, fully or partially fluorinated C<SUB>1</SUB>-C<SUB>6</SUB>alkyl or a group -SO<SUB>2</SUB>R<SUB>10</SUB> ; n is 0, 1 or 2; R<SUB>5</SUB> is C<SUB>1</SUB>-C<SUB>6</SUB>alkyl, fully or partially fluorinated C<SUB>1</SUB>-C<SUB>6</SUB>alkyl, C<SUB>1</SUB>-C<SUB>6</SUB>alkenyl, C<SUB>1</SUB>-C<SUB>6</SUB>alkynyl, optionally substituted aryl, or optionally substituted heteroaryl; R<SUB>6</SUB> is hydrogen, C<SUB>1</SUB>-C<SUB>6</SUB>alkyl or fully or partially fluorinated C<SUB>1</SUB>-C<SUB>6</SUB>alkyl ; R<SUB>7</SUB> and R<SUB>8</SUB> are independently hydrogen or C<SUB>1</SUB>-C<SUB>6</SUB>alkyl, or R<SUB>7</SUB> and R<SUB>8</SUB> together with the atom to which they are attached form a cycloalkyl group; and X is -CHR<SUB>6</SUB>-, -S(O)<SUB>n</SUB>-, -C(O)-, -NR<SUB>6</SUB>SO<SUB>2</SUB>- or -SO<SUB>2</SUB>NR<SUB>6</SUB>- wherein n is 0, 1 or 2.</p> |
