The present invention relates to compounds of the general formula (I) wherein (formula 2) independently represents a single bond or a double bond, represents a linking group A and A′ are each independently a 5- to 7-membered heterocyclic ring, wherein the heterocyclic rings A und A′ are optionally substituted by one or more substituents, selected from C
1-6
alkyl, C
3-6
cycloalkyl, optionally substituted phenyl, optionally substituted heteroaryl, C
1-4
alkylene-(optionally substituted phenyl) and C
1-4
alkylene-(optionally substituted heteroaryl), or two substituents may be joined to form an optionally substituted, saturated, unsaturated or aromatic 5- to 7-membered ring which is fused with the heterocyclic ring A or A′, and wherein the heterocyclic rings A und A′ may contain in addition to the units X, X′, Y and Y′ one or more heteroatoms, selected from N, NR, S and Ol wherein R is selected from H and C
1-4
alkyl; the units X and X′ are each independently a H-bond acceptor; and the units Y and Y′ are each independently a H-bond donor. The compound of formula (I) can be employed in the treatment of a group of disorders and abnormalities associated with amyloid protein, such as Alzheimer's disease, and of diseases or conditions associated with amyloid-like proteins. The compounds of the present invention can also be used in the treatment of ocular diseases associated with pathological abnormalities/changes in the tissues of the visual system.

The photolysis of the isoquinoline N-imides (12a-g) under basic conditions gave the corresponding 5H-2, 3-benzodiazepines (13), presumably via the 1H-2, 3-benzodiazepines (17), together with the parent isoquinolines (14), whereas irradiation of these N-imides (12) under neutral conditions gave no diazepines. Treatment of the 1-methyl-5H-diazepines (13b, f) with acetic anhydride gave the 3-acetyl-3H-2, 3-benzodiazepines (18), which reverted back to the 5H-diazepines (13) on hydrolysis. However, the 1-unsubstituted 5H-diazepines showed no such conversion. Some reactions of the 5H-diazepines (13) thus obtained were also examined.
