Expanding the universe of treatable diseases by harnessing the cell's natural mechanism for enhancing protein function

ENTAC™ drugs in action

At their core, ENTACs — enhancement-targeting chimeras — are molecular matchmakers. These small-molecule drugs bring together beneficial target proteins with enzymes called deubiquitinases, or DUBs, which are key regulators of protein function. DUBs work by selectively shortening or removing chains of a molecule called ubiquitin that are attached to proteins. Whether the target protein is in short supply, is in the wrong place within the cell, or has suboptimal activity, an ENTAC can be designed to recruit a DUB to fix the problem. By introducing each target to the right DUB, ENTACs enhance the function of these crucial proteins — many of which cannot be targeted with existing drugs — ultimately restoring the cell’s health.

Entact Bio’s CEO is leading the company out of stealth and into a new age of protein enhancement

Guiding a young, groundbreaking company to maturity calls for a leader who can strike the right balance between oversight and support. Victoria Richon is hoping to provide just that as the new CEO of Entact Bio, a preclinical biotech that came out of stealth in December...
