    • The invention provides the use of a photosensitizer which is 5-aminolevulinic acid (5-ALA) or a derivative (e.g. an ester) of 5-ALA, or a pharmaceutically acceptable salt thereof, in the manufacture of a composition for use in methods of photodynamic therapy (PDT) on an animal, wherein said PDT comprises: (a) administering to said animal a composition comprising said photosensitizer; and (b) photoactivating said photosensitizer, and wherein side-effects (e.g. pain and/or erythema) of said PDT are prevented or reduced by use of one or more of (i)-(iv): (i) said composition comprises said photosensitizer in a concentration of less than 10% wt (e.g. 0.5 to 8% wt), (ii) said composition is administered for less than 2 hours (e.g. 30 minutes to 90 minutes) prior to said photoactivation, (iii) said photoactivation is carried out with a light source having a fluence rate of less than 50 mW/cm2 (e.g. 5 to 40 mW/cm2), (iv) said photoactivation is carried out with sunlight. Preferably, side-effects of PDT are prevented or reduced by using (iii) or (iv) in combination with (i) and/or (ii).
    • 本发明提供了5-氨基乙酰丙酸(5-ALA)或5-ALA衍生物(例如酯)或其药学上可接受的盐的光敏剂在制备用于 光动力疗法(PDT),其中所述PDT包括:(a)向所述动物施用包含所述光敏剂的组合物; 和(b)光活化所述光敏剂,并且其中通过使用(i) - (iv)中的一种或多种来防止或减少所述PDT的副作用(例如疼痛和/或红斑):(i)所述组合物包含 浓度小于10%wt(例如0.5至8%wt)的光敏剂,(ii)所述组合物在所述光活化之前施用少于2小时(例如30分钟至90分钟),(iii)所述光活化是 用光通量小于50mW / cm2(例如5〜40mW / cm2)的光源进行,(iv)所述的光活化是在太阳光下进行的。 优选地,通过使用(iii)或(iv)与(i)和/或(ii)组合来防止或减少PDT的副作用。

    • The invention provides compounds for use in photochemotherapy or diagnosis, said compounds being branched alkyl esters or substituted alkyl esters of 5-aminolevulinic acid, or derivatives or pharmaceutically acceptable salts thereof. In particular, the invention provides compounds of formula (I): R22N—CH2COCH2CH2CO—OR1 (wherein R1 represents an optionally substituted branched alkyl (e.g. C5-30 alkyl) group, or a substituted alkyl group; R2, each of which may be the same or different, represents a hydrogen atom or an optionally substituted alkyl group, preferably a group R1; wherein said substituents are selected from hydroxy, alkoxy, acyloxy, alkoxycarbonyloxy, amino, aryl, nitro, oxo, fluoro, —SR3, —NR32 and PR32 groups, and each alkyl group is optionally interrupted by one or more O—, —NR3—, —S— or —PR3— groups; and R3 represents a hydrogen atom or a C1-6 alkyl group) and salts thereof for us in diagnosis and photochemotherapy of disorders of abnormalities of external or internal surfaces of the body, and products and kits for performing the invention.
