##STR1## The present invention provides novel substituted anthraquinones having formula (.alpha.), wherein R.sub.1 and R.sub.2 are independently H, C.sub.1 -C.sub.10 alkyl, aryl, arylalkyl, alkylaryl, or R.sub.1 and R.sub.2 taken together with the adjacent nitrogen atom N form a substituted or unsubstituted cyclic ring which may contain additional heteroatoms; n and m are independently 1, 2, or 3; A is halogen, OH, alkoxy, OCO(NR.sub.3 R.sub.4), S--C(NH.sub.2)=NR.sub.5, or when m=1, comprises an oxirane ring with the adjacent oxygen atom; R.sub.3, R.sub.4, and R.sub.5 are independently H, alkyl, or aryl; X is H, OH, NR.sub.6 R.sub.7, Cl, Br, I, F, alkyl, aryl, alkoxy, aryloxy, COOR.sub.8, or CONR.sub.9 R.sub.10 ; and R.sub.6, R.sub.7, R.sub.8, R.sub.9, and R.sub.10 are independently H, lower alkyl, or aryl useful for inhibiting protein kinase C and treating conditions related to, or affected by inhibition of protein kinase C, particularly cancer tumors, inflammatory disease, reperfusion injury, and cardiac dysfunctions related to reperfusion injury.
本发明提供了具有式(α)的新型取代蒽醌,其中R1和R2独立地为H,C1-C10烷基,芳基,芳基烷基,烷基芳基或R1和R2与相邻的氮原子N一起形成取代或未取代的环状环,该环可能含有额外的杂原子;n和m独立地为1、2或3;A为卤素,OH,烷氧基,OCO(NR3R4),S-C(NH2)=NR5,或当m=1时,包括与相邻的氧原子形成环氧环;R3、R4和R5独立地为H,烷基或芳基;X为H,OH,NR6R7,Cl,Br,I,F,烷基,芳基,烷氧基,芳氧基,COOR8或CONR9R10;R6、R7、R8、R9和R10独立地为H,低级烷基或芳基,用于抑制蛋白激酶C并治疗与蛋白激酶C抑制相关或受影响的疾病,尤其是癌症肿瘤,炎症性疾病,再灌注损伤和与再灌注损伤相关的心脏功能障碍。
