Spt4/Spt5 is an useful target as it is likely a transcription factor that has implications for long non-coding RNA repeats related to frontotemporal dementia (FTD) found in the C9orf72 disease pathology. Inhibitors for Spt4/Spt5 using peptides as a starting point for assays as a means for developing small molecules, which could likely lead to therapeutic development for inhibition for Spt4/Spt5 with CNS characteristics. To elucidate the specific steps of identification and modification of key interacting residues from Spt4/Spt5 complex with further effect prediction, a set of different computational methods was applied. Newly characterized, theoretically derived peptides docked on Spt4/Spt5 models, based on X-ray crystallography sources, allowed us to complete molecular dynamics simulations and docking studies for peptide libraries that give us high confident set of peptides for use to screen for Spt4/Spt5 inhibition. Several peptides with increased specificity to the Spt4/Spt5 interface were found and can be screened in cell-based assays and enzymatic assays for peptide screens that lead to small molecule campaigns. Spt4/Spt5 comprises an attractive target for neurological diseases, and applying these peptides into a screening campaign will promote the goal of therapeutic searches for FTD drug discovery.
