wherein A is
wherein R1, R2 and R3 are independently selected from H and alkyl;
wherein X is O, S, NR4 or a direct bond, wherein R4 is H or alkyl;
wherein Z is a saturated hydrocarbyl chain comprising from 1 to 20 carbon atoms interrupted by one or more heteroatom(s) and optionally substituted by one or more oxo substituent(s);
wherein q is 1, 2 or 3;
wherein if q is 2 or 3, then each A can be the same or different;
wherein the or each R5 is independently selected from H and alkyl;
wherein the or each R6 is independently selected from alkyl;
wherein n is 1 to 5;
wherein p is 0 to 4; and
wherein the sum of n and p is less than 6,
or a pharmaceutically acceptable salt thereof, and the use thereof in therapy, particularly for the treatment of a condition associated with oxidative stress, such as oxidative damage of the central nervous system or an acute or chronic neurological disorder such as traumatic brain injury, spinal cord injury, cerebral tumour, subharrachnoid haemorrage/cerebral vasospasm, cerebral ischaemia, stroke (ischaemic or haemorragic), Alzheimer's disease, Huntington's Disease, Parkinson's Disease, Friedrich's ataxia, motor neuron disease or multiple sclerosis.
