| Abstract | A tetrahydroaminoquinoline-based library was generated with the goals of finding small molecule modulators of protein-protein interactions. Several library members as well as other related intermediates were tested for their ability to bind to Bcl-XL and Mcl-1 by in silico and 15N NMR studies. The NMR study led to the identification of the tetrahydroaminoquinoline-based nude scaffold, 7 as a weak binder (Kd?=?200?[mu]M for Bcl-XL and Kd?=?300?[mu]M for Mcl-1) to both proteins. Using this scaffold as the starting material, we then synthesized a focused library of only 9 derivatives by applying the principles of a fragment-based approach. All these derivatives were then tested by NMR and this led to the discovery of a novel, small molecule (MIPRALDEN, 17) as a binder to Mcl-1 and Bcl-XL (KD?=?25 and 70?[mu]M). This finding is novel because to our knowledge there are not many small molecules known in the literature that bind to Mcl-1. |
