Description

Shakti P Pattanayak's team built AcTor in 2026, a first-of-its-kind stimulator of the mTOR pathway, to boost the leukemia drug ixazomib. Blocking mTOR can shield cancer cells during chemotherapy, so the team reasoned the opposite, activating mTOR by blocking its brake, TSC2, might sensitize cells to proteasome blockade. Computer docking and chemistry produced AcTor, tested alone and with ixazomib across leukemia lines and patient samples.

The pair collapsed mitochondrial energy, raised reactive oxygen, and drove cell death, with stronger effects in drug-resistant leukemia, and it shrank disease and stem-like cells in mice, including a TP53-mutant model. The authors warn AcTor must not be used alone in cancer. Leukemia teams get a counterintuitive combination strategy with animal proof, awaiting human safety data.
