A compound of the formula (1):
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 hydrocarbyl chain comprising from 2 to 10 carbon atoms and one or more carbon-carbon double bonds, the hydrocarbyl chain also being optionally 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.
化合物的式子(1):其中A为其中R1、R2和R3独立地选择自H和烷基;其中X为O、S、NR4或直接键,其中R4为H或烷基;其中Z为含有2到10个碳原子和一个或多个碳-碳双键的烃基链,该烃基链也可以被一个或多个杂原子打断,并且也可以被一个或多个氧代取代基取代;其中q为1、2或3;其中如果q为2或3,则每个A可以相同或不同;其中每个R5独立地选择自H和烷基;其中每个R6独立地选择自烷基;其中n为1到5;其中p为0到4;并且n和p的总和小于6,或其药学上可接受的盐,以及其在治疗中的用途,特别是用于治疗与氧化应激有关的疾病,例如中枢神经系统的氧化损伤或急性或慢性神经系统疾病,如创伤性脑损伤、脊髓损伤、脑肿瘤、蛛网膜下腔出血/脑血管痉挛、脑缺血、中风(缺血性或出血性)、阿尔茨海默病、亨廷顿病、帕金森病、弗里德里希共济失调症、运动神经元病或多发性硬化症。
