tyrosine receptor kinase 3 (FLT3) is implicated in the pathogenesis of acute myeloid leukemia (AML) in 20-30% of patients. In this study we identified a highly selective (phenylethenyl)quinazoline compound family as novel potent inhibitors of the FLT3-ITD and FLT3-D835Y kinases. Their prominent effects were confirmed by biochemical and cellular proliferation assays followed by mice xenograft studies

This work presents the design and synthesis of a series of new quinazolin-4-one derivatives, based on the established effectiveness of quinazoline-based small molecules as anticancer agents. Synthesized compounds were more potent against MCF-7 than A-549 with low to submicromolar IC50s. Compound 17 exhibited the best IC50 being equipotent with the positive control doxorubicin (IC50 = 0.06 μM) and better

The present invention relates to styryl quinazoline derivatives of the general formula (I) and pharmaceutically acceptable solvates, hydrates, salts, regioisomeric and polymorphic forms thereof as well as pharmaceutical compositions containing at least one of the described compounds as pharmaceutically active agent. The compounds have been identified as new drug candidates for the prevention and/or treatment of diseases related to disfunction(s) of hematopoiesis and cancer or any other form of neo- or hyperplasias related to Fms-like tyrosine kinase 3 (FLT3) containing Internal Tandem Duplications (ITD), especially in the case of myeloid leukemia. The compounds have been also identified as new drug candidates as antibacterial agents (having bactericidal or bacteriostatic activity) which can be used for the prevention and/or treatment of bacterial infectious diseases.
The invention encompasses 2-[4-(imidazolyl)-phenyl]vinyl-heterocycle derivatives which selectively attenuate production of Abeta(1-42) and are useful in the treatment of Alzheimer's disease. Pharmaceutical compositions and methods of use are also encompassed.
