Investigation the cytotoxicity of newly synthesized quinazo-line–sulfonamide derivatives in human leukemia cell lines and hematopoietic activity in zebrafish embryos.

<p>These videos contain the time lapse imaging of the wild type&nbsp; zebrafish embryos showing the circulation, control (mock 0.5% V/V DMSO) and compound 4a treated embryos at 72 hours post fertilization. The compound 4a specifically blocked the formation of blood and no circulation was seen in these embryos.&nbsp;</p>
