Patent ID: 7186840

Claim:
A compound selected from the group of compounds represented by Formula I: wherein: A is a —CH 2 —, CH(OH), —C(O)—, C═NOR 4 , —NR 5 —, —O—, —S—, —S(O)—, or —S(O) 2 —, where R 4 is hydrogen or alkyl and R 5 is hydrogen, alkyl, or acyl; Ar is an optionally substituted phenyl; R 1 is —OSO 2 R 11 where R 11 is selected from alkyl, cycloalkyl, and haloalkyl; R 2 is hydrogen, alkyl, alkenyl, alkoxy, hydroxy, halo, haloalkyl, heteroalkyl, alkylsulfanyl, alkylsulfinyl, alkylsulfonyl, nitro, cyano, or —NR 9 R 10 where R 9 and R 10 are each independently selected from hydrogen, alkyl, and acyl; and R 2 represents substitution at any one of carbons C3, C4, C7 or C8; R 3 is —SR 12 , SOR 12 , SO 2 R 12 , or SO 2 NR 13 R 14 wherein, R 12 is alkyl, hydroxyalkyl, alkoxyalkyl aminoalkyl, mono or dialkylaminoalkyl, carboxyalkyl, or alkoxycarbonylalkyl; R 13 is hydrogen or alkyl, and R 14 is hydrogen, alkyl, cycloalkyl, cycloalkylalkyl, bydroxyalkyl, alkoxyalkyl, alkoxycarbonylalkyl, aminoalkyl, aryl, or aralkyl; or R 13 and R 14 together with the nitrogen atom to which they are attached form a heterocycloamino group; and pharmaceutically acceptable salts thereof.
