Claim:
A compound of the formula (II) or a pharmaceutically acceptable salt thereof, wherein R 9 , R 12 and R 14 are H; or two of R 9 , R 12 and R 14 are H; and the remaining of R 9 , R 12 and R 14 is (a) —NH 2 , (b) —NHR 6 , (c) —NR 6 R 7 , (d) —N(CO)R 6 , (e) —N(CS)R 6 , or (f) —NO 2 ; R 10 is a group R 3 ; R 11 is a group R 1 ; in which each of R 1 and R 3 , independently, is: (a) H (b) C 1-6 alkyl, (c) C 1-6 alkoxy, (d) straight or branched C 1-6 hydroxyalkyl, (e) straight or branched C 1-6 alkylhalides; or (f) a group Ar; Ar is (a) phenyl, (b) 1-naphthyl, (c) 2-naphthyl, (d) benzyl, (e) cinnamoyl, (f) a 5 to 7-membered, partially or completely saturated, heterocyclic ring containing 1 to 4 heteroatoms, selected from oxygen, nitrogen and sulfur, or (g) a bicyclic ring system consisting of two heterocyclic rings as defined under (f), or a bicyclic ring system consisting of one benzene ring and one heterocyclic ring as defined under (f); optionally, the group Ar is substituted with (a) Y, or (b) a 5 to 7-membered, partially or completely saturated, heterocyclic ring each containing 1 to 4 heteroatoms selected from oxygen, nitrogen or sulfur; Y is (a) H, (b) halogen, (c) C 1-6 alkyl, (d) CF 3 , (e) hydroxy, (f) C 1-6 alkoxy, (g) C 1-4 alkenyl; (h) phenyl; (i) phenoxy, (j) benzyloxy, (k) benzoyl, (l) OCF 3 , (m) CN, (n) straight or branched C 1-6 hydroxyalkyl, (o) straight or branched C 1-6 alkylhalides, (p) NH 2 , (q) NHR 6 , (r) NR 6 R 7 , (s) NO 2 , (t) —CONR 6 R 7 , (u) NHSO 2 R 6 , (v) NR 6 COR 7 , (x) SO 2 NR 6 R 7 , (z) —C(═O)R 6 , (aa) —CO 2 R 6 , or (ab) S(O) n R 6 ; wherein n is 0, 1, 2 or 3; R 13 is R 6 and R 7 are independently (a) H, (b) C 1-6 alkyl, (c) C 3-7 cycloalkyl, or (d) Ar, as defined above for R 1 ; alternatively, R 6 and R 7 are linked to form a group (CH 2 ) 3-5 ; R 8 is (a) H, or (b) C 1-6 alkyl.
