AC-100 is a novel synthetic peptide derived from an endogenous human protein produced by bone and dental cells (a fragment from matrix extracellular phosphoglycoprotein). It is being developed by Acologix, Inc.



Investigated for use/treatment in periodontal disease.


In animal models, AC-100 promoted cartilage regeneration. In the study, goats with an osteochondral femoral condylar (knee cartilage) defect were used to evaluate the effects of AC-100 on cartilage regeneration. Cylindrical defects were created in the knee cartilage and were filled with a collagen s... Read more

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-... Read more
