Targeted inhibitors
WebThe target of rapamycin (known as mTOR or the mechanistic target of rapamycin) is a protein that tells cells when to grow, divide, and survive. mTOR often mutates in cancer cells, leading to uncontrolled tumor cell growth. Although originally developed as an antifungal agent, rapamycin was found to substantially suppress the immune system ... Targeted covalent inhibitors (TCIs) or Targeted covalent drugs are rationally designed inhibitors that bind and then bond to their target proteins. These inhibitors possess a bond-forming functional group of low chemical reactivity that, following binding to the target protein, is positioned to react rapidly with a proximate nucleophilic residue at the target site to form a bond.

WebResults and discussion Structure–activity relationship study We envisioned that the mitochondria-targeting peptides developed by Kelley and co-workers 37–39 could be starting points for mechanism-based inhibitors of sirtuins. It was hypothesized that such inhibitors could be designed by incorporating a thiocarbonyl-containing lysine residue … WebMedicines known as monoclonal antibodies can be designed to target these checkpoint proteins. These drugs are called immune checkpoint inhibitors (or just checkpoint inhibitors). Checkpoint inhibitors don't kill cancer cells directly. They work by helping the immune system to better find and attack the cancer cells, wherever they are in the body.
