<p>The invention provides compounds having formula (I) wherein: R1, R2, R3, R4, R5 and R6, independently, are H, halo, methoxy or hydroxyl, provided that at least one of R1, R2, R3, R4, R5 and R6 is hydroxyl, R7 and R8 are H or taken together form a carbonyl; R12 and R13 are H or taken together form a carbonyl; A is H or CR9R10R11; R9 and R10 are H or taken together form a carbonyl; R11 is H, C1 - C17 alkyl, C1 - C17 alkenyl, C1 - C17 alkynyl, or aryl; and, R14 and R15, independently are H, halo, methoxy or hydroxyl when at least 5 of R1 - R6 are hydroxyl, and H when less than 5 of R1 - R6 are hydroxyl. The compounds are useful for inhibiting protein kinase C, and treating conditions affected by protein kinase C activity, particularly cancer tumors, inflammatory disease, reperfusion injury and cardiac dysfunctions related to reperfusion injury.</p> |
