A set of new dihydro-1H-pyrazolo[1,3-b]pyridine and pyrazolo[1,3-b]pyridine embelin derivatives was synthesized through a multicomponent reaction from natural embelin, 3-substituted-5-aminopyrazoles and aldehydes. The synthesized compounds were evaluated against three hematologic tumor cell lines, HEL (acute erythroid leukemia), K-562 (chronic myeloid leukemia) and HL-60 (acute myeloid leukemia), and five breast cancer cell lines (SKBR3, MCF-7, MDA-MB-231, BT-549, HS-578T). The primate non-malignant kidney Vero cell line was used as the control of cytotoxicity. From the obtained results, some structure–activity relationships were out-lined. Furthermore, in silico prediction of physicochemical properties and ADME parameters were determined for the derivatives with the best antiproliferative values.

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 C1-6 alkyl, C3-6 cycloalkyl, optionally substituted phenyl, optionally substituted heteroaryl, C1-4 alkylene-(optionally substituted phenyl) and C1-4 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 C1-4 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.
