The invention provides mitochondria-targeted chemiluminescent agents and their use in methods of photodynamic therapy (PDT). In particular, the invention provides compounds of general formula (I), and their pharmaceutically acceptable salts: (I) in which A represents a chemiluminescent moiety; each L, which may be the same or different, is either a direct bond or a linker; each B, which may be the same or different, represents a mitotropic moiety; n is an integer from 1 to 3, preferably 1; and x is an integer from 1 to 3, preferably 1. Such compounds find particular use in the treatment of deeply- sited tumours, e.g. glioblastoma multiforme (GBM), when used in combination with a photosensitizer or photosensitizer precursor.
triplet energy was greatly improved, and then, it could markedly promote the efficient geometrical isomerization of alkenes from the E-isomer to the Z-isomer. Moreover, it was also effective for energy-transfer-mediated organometallic catalysis, which allowed realization of the cross-coupling of aryl bromides and carboxylic acids through efficient energy transfer from HiBRCP to nickel complexes. Thus, the
catalytical activity for substrates with low reactivities is always highly desired. Herein, based on the principle of structure–property relationships, we rationallydesigned the natural product cercosporin, the naturally occurring perylenequinonoid pigment, to develop a novel organic perylenephotoreductant, hexacetyl reduced cercosporin (HARCP), through structural manipulation. Compared with cercosporin

The totalsyntheses of the PKC inhibitors (+)-calphostin D, (+)-phleichrome, cercosporin, and 10 novel perylenequinones are detailed. The highly convergent and flexible strategy developed employed an enantioselective oxidative biaryl coupling and a double cuprate epoxide opening, allowing the selective syntheses of all the possible stereoisomers in pure form. In addition, this strategy permitted rapid
