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

atropisomeric resorcinol-bearing quinazolinones have been developed. Utilizing a new guanidinylated dimeric peptidic ligand, a set of products were generated in good yields with excellent stereocontrol. The transformation was readily scalable, and a range of product derivatizations were performed.

Condensation of 4‐(3H)‐quinazolinone (2) with 4‐(aminophenyl)‐mercaptoacetic acid under the conditions of the Mannich reaction furnished compounds 3a and 3b. Reaction of 4 with 4‐(amino‐phenyl)mercaptoacetic acid yielded 5 which when treated with aryl aldehydes gave 6. Similarly, compounds 8 were obtained from 7.

We recently reported on the discovery of a novel antibacterial (2) with a 4(3H)-quinazolinone core. This discovery was made by in silico screening of 1.2 million compounds for binding to a penicillin-binding protein and the subsequent demonstration of antibacterial activity against Staphylococcus aureus. The first structure–activity relationship for this antibacterial scaffold is explored in this report
Synthesis and evaluation of new quinazolin-4(3H)-one derivatives as potent antibacterial agents against multidrug resistant Staphylococcus aureus and Mycobacterium tuberculosis
demonstrated equipotent MIC against multiple drug-resistant strains of S. aureus including VRSA, concentration dependent bactericidal activity against S. aureus and synergized with FDA approved drugs. Moreover, compound 4′c exhibited more potent activity in reducing the biofilm and exhibited a PAE of ∼2h at 10X MIC which is comparable to levofloxacin and vancomycin. In vivo efficacy of 4'c in murine neutropenic
