5 Pharmacology and Biochemistry
5.1 Mechanism of Action

In several preclinical models, AC-100 has demonstrated potent and selective dental tissue and bone formation activity, however the exact mechanism is not known. One study (PMID:15153459) showed that AC-100 enhances dental pulp stem cell (DPSC) proliferation by down-regulating P16, accompanied by up-regulation of ubiquitin protein ligase E3A and human ubiquitin-related protein SUMO-1. Enhanced cell proliferation required intact RGD and SGDG motifs in the peptide. This study shows that AC-100 can promote DPSC proliferation, with a potential role in pulp repair.
