Identification of new 4-N-substituted 6-aryl-7H-pyrrolo[2,3-d]pyrimidine-4- amines as highly potent EGFR-TK inhibitors with Src-family activity

The epidermal growth factor receptor is an important target in molecular cancer therapy. Herein, the enzymatic inhibition potential of a series of chiral and non chiral pyrrolopyrimidine based derivatives have been investigated and optimised. Overall, seven new compounds were identified having enzymatic IC 50 values comparable to or better than the commercial drug Erlotinib. High activity was also confirmed towards the epidermal growth factor receptor L858R and L861Q mutants. Based on calculated druglike properties, eight compounds were further evaluated towards a panel of 52 other kinases revealing interesting Src-family kinase and colony stimulating factor 1 receptor kinase inhibitory activity. Cell proliferation studies with the cell lines A431, C-33A, AU-565, K-562 and genetically engineered Ba/F3-EGFRL858R cells also showed several molecules to be more active than Erlotinib, and thus confirming these pyrrolopyrimidines as attractive drug candidates or lead structures.

Activity of 6-aryl-pyrrolo[2,3-d]pyrimidine-4-amines to Tetrahymena

A series 6-aryl-pyrrolo[2,3-d]pyrimidine-4-amines (43 compounds), some of which are epidermal growth factor tyrosine kinase inhibitors, were tested for their protozoal toxicity using an environmental Tetrahymena strain as model organism. The protozoacidal activity of the analogues was found to be highly dependent on a 4-hydroxyl group at the 6-aryl ring, and a chiral 1-phenylethanamine substituent in position 4. Further, the potency was affected by the aromatic substitution pattern of the phenylethanamine: the unsubstituted, the meta-fluoro and the para-bromo substituted derivatives had the lowest minimum protozoacidal concentrations (8-16 μg/mL). Surprisingly, both enantiomers were found to have high potency suggesting that this compound class could have several modes of action. No correlation was found between the compounds protozoacidal activity and the in vitro epidermal growth factor receptor tyrosine kinase inhibitory potency. This suggests that the observed antimicrobial effects are related to other targets. Testing towards a panel of kinases indicated several alternative modes of action.

FUSED BICYCLIC PYRIMIDINES AS PTK INHIBITORS CONTAINING A ZINC BINDING MOIETY

The present invention relates to fused bicyclic pyrimidine containing zinc- binding moiety based derivatives that have unique properties as protein tyrosine kinase (PTK) inhibitors and their use in the treatment of PTK related diseases and disorders such as cancer. The said derivatives may further act as HDAC inhibitors.

MULTI-FUNCTIONAL SMALL MOLECULES AS ANTI-PROLIFERATIVE AGENTS

The present invention relates to the compositions, methods, and applications of a novel approach to selective inhibition of several cellular or molecular targets with a single small molecule. More specifically, the present invention relates to multi-functional small molecules wherein one functionality is capable of inhibiting histone deacetylases (HDAC) and the other functionality is capable of inhibiting a different cellular or molecular pathway involved in aberrant cell proliferation, differentiation or survival.
