<p>Substituted Indoles 2-(pyridyl and imidazolyl)-indoles of formula I (I) wherein R1 represents hydrogen or lower alkyl; Ar represents 3-pyridyl or 1-imidazolyl, each unsubstituted or substituted by lower alkyl, carboxy, lower alkoxycarbonyl or carbamoyl; R2 and R3 independently represent hydrogen, lower alkyl, halogen, trifluoromethyl, hydroxy, lower alkoxy, carboxy lower alkyl, lower alkoxycarbonyl lower alkyl, carboxy, lower alkoxycarbonyl, or lower alkyl-(thio, sulfinyl or sulfonyl), or R2 and R3 together on adjacent carbon atoms represent lower alkylenedioxy; A represents alkylene of 3 to 12 carbon atoms in which the number of the carbon atoms separating the indole nucleus from group B is 3 to 12, alkenylene of 2 to 12 carbon atoms, alkynylene of 2 to 12 carbon atoms, lower alkylenephenylene-lower (alkylene or alkenylene), lower alkylenephenylene, lower alkylene-(thio or oxy)-lower alkylene, lower alkylene-(thio or oxy)-phenylene, or lower alkylenephenylene-(thio or oxy)-lower alkylene; B represents carboxy, esterified carboxy, carbamoyl, mono- or di-lower alkylcarbamoyl, hydroxymethyl, cyano, hydroxycarbamoyl, 5-tetrazolyl or formyl; the imidazolyl and pyridyl N-oxides thereof; and salts thereof pGssess thromboxane synthetase inhibitory properties. The compounds are manufactured according to processes known per se.</p> |
