Free-energy calculations and machine learning uncover diverse p38α–MK2 molecular glues

  • Glue-type inhibitors that bridge p38α and MK2 act longer than classic active-site blockers, but the ternary-complex mechanism makes rational design hard.
  • The team combined free energy perturbation with machine learning to rank compounds drawn from varied chemical sources in silico.
  • This yielded several structurally distinct, potent, selective glues; two leads showed good exposure and cut TNFα in an LPS mouse model after oral dosing.
💡 Points Based on the abstract

A team would next point this FEP-plus-ML triage at its own induced-proximity target, but first ask for the missing control: how did the ranking beat plain docking or a similarity screen on hit rate? For glues I'd also want cooperativity (ternary versus binary affinity) and residence time reported, since those, not potency alone, explain the durable effect.
