Abstract
In our ongoing efforts to discover new potent histone deacetylase (HDAC) inhibitors as promising anticancer candidates, we designed and synthesized a small collection of 3-substituted amines possessing macro heterocyclic skeletons bearing variable-length tails. As a metal binder domain, all the compounds possess an amide function suitable for Zn2+ chelation in the enzyme active site. A combination of solution and solid phase techniques were employed to synthesize the compounds and, as the key synthetic step to obtain the rings, a ring closing metathesis (RCM) reaction was adopted. The putative affinity of the compounds for the histone deacetylase-like protein (HDLP) model receptor active site was explored through docking calculations, and we also report preliminary studies on their pharmacological properties.
