Crystal structure of compound 4a in complex with cdk5, showing an unusual binding mode to the hinge region via a water molecule. CDK5 carries an Open Targets association of 0.68 with Alzheimer disease, and its small-molecule tractability reads advanced clinical, druggable family, high-quality ligand, med-quality pocket, structure with ligand. The receptor here is chain A of 4AU8 with waters and heteroatoms stripped and hydrogens added at pH 7.4; its sha256 is pinned in every record so a changed file would change every hash downstream.
The crystallised drug is re-docked by us, five times at seed 42, and the five runs have to return the same number. That number is the reference score. A submission wins when it is at or below the reference minus 0.5 kcal/mol, published per target, so a difference inside the method's own noise never pays.
The reference ligand passes the same filters a submission has to pass, which is the precondition for using it as the number to beat.
0 commits are on chain for this pocket. The order is the chain's: a commit is placed by its slot, then by its index inside that slot, and a later commit waits while an earlier one is still inside its window of 1500 slots. Submit a molecule from your wallet or run it through the SDK.
No submission yet. A commit appears here the moment it lands, and its status follows the records.
Fetch the pinned verifier from this site and run the same molecule against the same file. The score comes back identical, because the seed, the exhaustiveness, the CPU count, the box and the receptor hash are all fixed and published. The target files are fetched from here on first use.

The verifier prints the filter table, the score and the result hash as JSON. With --expect it compares the hash with the one in the settlement record and exits non-zero if they differ. The five files are also served one by one under /verifier/.
