Patent ID: 8742119

Claim:
A compound selected from one of formulas (Ia)-(Ie): wherein A, B, D and E are each independently selected from H, R 3 and —SO 2 —NR 4 R 5 , wherein at least one of A, B, D and E is —SO 2 —NR 4 R 5 ; each R 4 is independently selected from C 1-8 alkyl, aryl and heteroaryl, each of which is substituted with n occurrences of R 2 ; each R 5 is independently hydrogen or C 1-8 alkyl; each R 1 is independently selected from hydrogen, C 1-8 alkyl, C 1-8 terminal alkynyl, C 1-8 alkoxy, halogen, haloalkyl and haloalkoxy; each R 2 is independently selected from halo, haloalkyl, C 1-4 alkyl, C 2-4 alkenyl, C 2-4 alknynyl, aryl, heteroaryl, aralkyl, heteroaralkyl, cyano, —OR a and —COOR b ; wherein two R 2 , together with the carbons to which they are attached, may form an optionally substituted ring, each of which can be further substituted; each R 3 is independently selected from —OR a , halogen, haloalkyl, haloalkoxy and optionally substituted heteroaryl; each R a is independently selected from alkyl, haloalkyl, optionally substituted heteroaryl and optionally substituted heterocyclyl; each R b is independently alkyl; each R c is independently selected from hydrogen and alkyl; and n is 0, 1, 2 or 3.
