摘要

SULFONAMIDO HETEROCYCLIC THROMBIN INGIBITORS Sulfonamido heterocyclic thrombin inhibitors are provided which have the structure <IMG> wherein G is <IMG> or <IMG> including all stereoisomers thereof and salts thereof, wherein n is 0, 1 or 2 or 3; m is 0, 1, 2 or 3; Y is NH or S; p is 0, 1 or 2, Q is a single bond or <IMG> A is aryl, cycloalkyl, azacycloalkyl or azaheteroalkyl; R is hydrogen, hydroxyalkyl, aminoalkyl, alkyl, cycloalkyl, amidoalkyl, arylalkyl, alkenyl, aryl, alkynyl, arylalkoxyalkyl, or an amino acid side chain; R1 and R2 are independently hydrogen, lower alkyl, cycloalkyl, aryl, hydroxy, alkoxy, keto, thioketal, thioalkyl, thioaryl, amino or alkylamino; or R1 and R2 can be taken together with the carbons to which they are attached to form a cycloalkyl, aryl or heteroaryl ring; R3 is lower alkyl, aryl, arylalkyl, heteroaryl, quinolinyl or tetrahydroquinolinyl; and R4 can be guanidine, amidine or aminomethyl; where A includes a hetero atom, R4 is amidino; otherwise it may be any of the R4 moieties set out above.
