peer reviewedIn this report, we present a novel histone deacetylase inhibitor (HDACi) (N-Hydroxy-6-(5-nitro-naphtalimide)-hexanamide: ES8) that
efficiently inhibits angiogenesis in relevant ex vivo models (Human umbilical vein endothelial cells (HUVEC), 3D aortic ring assay)
and in vivo (chick chorioallantoic membrane (CAM), Zebrafish).
Transcriptomic profiling reveals a set of ES8 specific genes that are not affected by the prototypical HDACi suberoylanilide hydroxamic
acid (SAHA). Finally, ES8 also reduced tumor growth in mouse models of small cell lung cancer. Availability of a novel compound not
centered exclusively on inhibition of angiogenic factors and inducing a characteristic transcription profile may be of interest to overcome resistance to currently used chemotherapies
