Abstract: A method of treatment of a disease of the human or animal body mediated by PARP comprising administering to such a subject a therapeutically effective amount of a compound of formula: or an isomer, salt, solvate, chemically protected form, and prodrug thereof, wherein: A and B together represent an optionally substituted, fused aromatic ring; RC is represented by -L-RL, where L is of formula: —(CH2)n1-Qn2-(CH2)n3— wherein n1, n2 and n3 are each selected from 0, 1, 2 and 3, the sum of n1, n2 and n3 is 1, 2 or 3 and Q is selected from O, S, NH, C(?O) or —CR1R2—, where R1 and R2 are independently selected from hydrogen, halogen or optionally substituted C1-7 alkyl, or may together with the carbon atom to which they are attached form a C3-7 cyclic alkyl group, which may be saturated (a C3-7 cycloalkyl group) or unsaturated (a C3-7 cycloalkenyl group), or one of R1 and R2 may be attached to an atom in RL to form an unsaturated C3-7 cycloalkenyl group which comprises the carbon atoms to which R1 and R2 are a

Abstract: A compound of formula: or an isomer, salt, solvate, chemically protected form, or prodrug thereof, wherein A and B together represent an optionally substituted, fused aromatic ring; RL is a C5-7 aryl group substituted in the meta position by the group R2, and optionally further substituted; wherein R2 is selected from: and its use as a pharmaceutical, in particular for the treatment of diseases ameliorated by inhibiting the activity of PARP.
