We proposed that increased C/EBP expression and/or activity in AML can lead to myeloid differentiation and exhibited that styryl quinazolinone analogue (1), induces C/EBP activity which in turn enhances differentiation and leads to growth arrest and apoptosis of leukemic cells.5 We further explored a series of styryl quinazolinones and identified 2 as potent C/EBP inducer.6 Among various heteroaryls in development as drugs quinazolinone7 also finds significance. Styryl quinazolinones are well studied for applications as anti-bacterials8 and as anticancer drugs.9 The interesting aspect of styryl quinazolinones is that they were explored as Heat shock protein 90 (HSP90) inhibitors,10 tubulin polymerization inhibitors,11,12 RAD51 inhibitors,13,14 and also cause shortening of telomeres.15 From our high throughput screen5 and subsequent development,6 we found that styryl quinazolinones induce C/EBP expression in HL-60 cells and there by induce myeloid differentiation. We hypothesized that there may be connectivity between all these protein targets and styryl quinazolinones. We were driven to postulate the exact mechanism and pathway of the drug action and hence we screened a series of structurally variant styryl quinazolinones such as styryl quinazolinones, ethynyl styryl quinazolinones, thienopyrimidinones, styryl quinolinones to see same phenotypic myeloid differentiation.
