Abstract: Compounds of formula I ##STR1## in which R.sub.1, R.sup.2 are the same or different and denote a hydrogen atom, an alkyl group, a cycloalkyl group, a hydroxyalkyl group, an alkenyl group, an alkinyl group or an aralkyl group or R.sup.1 and R.sup.2 together denote an alkylene residue which, together with the bound oxygen atoms and the phosphorus atom carrying the oxygen atoms, forms a saturated 5-membered to 8-membered ring;R.sup.3 denotes an optionally substituted amino group, an alkyl group, a cycloalkyl residue or an optionally substituted aryl residue;n denotes an integer between 1 and 4,as well as hydrates, solvates and physiologically tolerated salts thereof, their optically active forms, processes for their production as well as pharmaceutical preparations having factor Xa-inhibitory properties which contain these compounds.

Abstract: The invention concerns new 4-aminopyridazines of the general formula I ##STR1## in which R.sup.1 denotes an R.sup.2 --SO.sub.2 --O-- or R.sup.2 --SO.sub.2 --NR.sup.3 -- group in whichR.sup.2 denotes a cycloalkyl residue, an unsubstituted or substituted aryl or heteroaryl residue,R.sup.3 denotes a hydrogen atom, an alkyl or alkyloxyalkyl group which can be unsubstituted or substituted once or several times by hydroxy groups wherein the hydroxy groups can be substituted by alkyl, hydroxyalkyl, alkyloxyalkyl, hydroxyalkyloxyalkyl or alkylcarbonyl groups and wherein in each case two vicinal hydroxy groups can be linked together by alkylidene groups,as well as hydrates, solvates and physiologically tolerated salts thereof. The invention also concerns the optically active forms, racemates and mixtures of diastereomers of these compounds, processes for their production and pharmaceutical agents containing these compounds having a thrombin-inhibiting action.
