Abstract

Matchpoint Therapeutics has publicly launched with $70 million in series A financing and an earlier $30 million in seed money to develop covalent drugs for immune diseases. Its founders include Stanford University chemical biologist Nathanael Gray and Harvard Medical School cell biologist Edward Chouchani. Covalent drugs, once considered fringe players , have been gaining traction among drug developers for their ability to form long-lasting bonds with their protein targets. Unlike drugs that form reversible, noncovalent interactions, covalent compounds permanently shut down the disease-linked proteins they bind to, resulting in a potent therapy with a long action time. Selectivity is the name of the game to ensure that the compounds don’t stray to the wrong targets and cause side effects. Matchpoint will initially pursue compounds that latch to cysteines on their protein targets. Cysteine is the most popular covalent docking site among amino acid residues for its strong nucleophilicity and low
