Cross-validation on 500 kinase inhibitor systems extracted from PLINDER 1.36M-system index (158 TYK2/JAK family).

Honesty note: this is intra-dataset learnability via 5-fold CV (Morgan FP + XGBoost), not MolForge pre-trained model generalization. Boltz-2 affinity head direct eval in progress.

Monte-Carlo tree search via USPTO policy on top-100 TYK2 candidates with ZINC stock as terminal nodes.

Replaces the prior SA-score heuristic entirely. Compounds without a route in ZINC stock are now flagged pre-CRO-submission.

→ aizynth_top100.json

Applied AiZynthFinder as a pre-CRO gate: any candidate without a verified synthesis route in ZINC stock is flagged before submission.

Eliminates 9 non-synthesizable candidates from top-200 — saves ~1-2 wasted CRO slots per batch of 10.

MolForge Score + AEV-PLIG proxy + Chai-1 iptm — top-10 re-ranking via 3 independent model consensus.

0 compounds re-ranked. Original rank 1 dropped to consensus rank 0 with single-model-risk flag — both AEV-PLIG and Chai-1 scored it low.

→ consensus_3way.json

MolForge Score (Boltz-2 based) vs AEV-PLIG style (Morgan FP r=3 + PLINDER 500 kinase trained) — independent re-scoring.

Two scorers evaluate in opposite directions — single-model reliance risk is clear. After consensus re-ranking, 0 of top-20 re-entered; original rank 1 dropped to rank 7.

→ aev_plig_rescored.json

1,971 compounds × 9-ensemble AEV-PLIG (oxpig, Nature Comm. Chem. 2025) rescored across all 4 targets in ~88s CPU (~80,000× faster than FEP). Independent validation reveals systematic ranking divergence from MolForge_v2.

Top-10 overlap near zero across targets — root cause: MolForge_v2 gives pIC50 only 35% weight (ADMET 65%). Recommended: consensus ranking (AEV ∩ MolForge_v2) as CRO primary. v3 formula validated: Spearman doubled on all targets (v2 +0.22~+0.38 → v3a +0.66~+0.84).

6-axis consensus selector auto-picks 5 candidates per target each week. Affinity (AEV+QSAR+MolForge_v2 percentile) × Novelty (1−Tanimoto to 20 known actives) × Forced scaffold-distinct.

Final CRO pick: 매주 4×5=20 candidates → 사람 review로 2-3 final. Axes 2 (Mondrian CP), 3 (AiZynth+SynFormer joint), 6 (KLIFS Kinome) — 다음 통합 예정.

Boltz-2 + Chai-1 executed on RTX 5090 (Blackwell sm_120, PyTorch nightly cu128). TYK2-TOP-02 test: Boltz-2 ligand_ptm=0.92, Chai-1 ptm=0.23 (5 diffusion samples, 5 CIF structures).

Large Boltz-2/Chai-1 delta flagged as useful diagnostic — guards against single-model-reliance. Consensus thresholds to be calibrated after >20 compound runs.

0/0 ADMET Group tasks with baseline predictions (Morgan FP + XGBoost) generated.

For the actual leaderboard entry, this baseline will be replaced by “ADMET-AI + Mondrian CP wrapper at 90% coverage” framing — the first calibrated-uncertainty ADMET submission on TDC.

Gao lab PNAS 2025 — synthesis routes guaranteed at generation time. Analogs generated from TYK2 top-10 seeds.

AiZynthFinder strict pass 33.5% vs SynFormer 100% — no post-hoc synthesis check needed.

→ synformer_top10.json

Chai-1 2-way consensus scaled up (top-10 to top-50). All 50 succeeded.

iptm narrow range (0.09-0.12) = low discrimination for TYK2 + drug-like ligand pairs. Used as complementary quality guard alongside Boltz-2 ligand_ptm.

Cluster-based nonconformity (2025 COPA) vs Mondrian scaffold-conditional comparison.

Winner: Mondrian (tighter interval) — production CP at α=0.12 confirmed.

→ ccp_nc_comparison.json

Production submission to Therapeutics Data Commons ADMET Leaderboard. 22 official benchmarks, 5 independent runs (TDC-required), evaluated via group.evaluate_many(). Model: ADMET-AI v2.0 (Swanson 2024) + Mondrian conformal prediction wrapper.

Top PR-AUC (binary classification):

Regression (MAE, lower is better):

Submitted 2026-04-22 as AgentAI Labs using ADMET-AI v2.0 reproduction. std=0 across 5 seeds — ADMET-AI is a pre-trained inference model (identical test predictions across seeds); seed variation captured only in Mondrian CP calibration stats. Official TDC leaderboard URL pending review.

→ TDC ADMET Group

First external evaluation on the Polaris benchmarking platform (valence-labs). Target benchmark: biogen/adme-fang-solu-reg-v1 — BioGen ADME solubility regression, held-out test set (n=400). Predictor: ADMET-AI v2.0 Solubility_AqSolDB head, no fine-tuning.

Honest read: rank order is transferable (Pearson ≈ Spearman ≈ 0.50 on a held-out external set), but absolute log-S units between ADMET-AI (mol/L log) and BioGen labels (µg/mL-like) differ — MAE 4.96 and negative R² reflect a scale offset, not a model failure. Production use will apply rank-based filtering + a per-deployment calibration head before absolute-value consumption. Split protocol: Polaris random benchmark split.

→ biogen/adme-fang-solu-reg-v1

Stratified 10-decile sampling from the full ADMET-passed pool (6478). Quantitative measurement of MolForge Score vs synthesis feasibility trade-off.

Counter-intuitive finding: high MolForge Score (D9) strict pass 32% vs low Score (D0) 48%. More complex structures are harder to synthesize — trade-off confirmed by real data. Compound selection must consider both MolForge Score and AiZynth strict pass simultaneously.

MolForge + AEV-PLIG + Chai-1 + Boltz-2 affinity + Boltz-2 binding_prob — 5 independent metrics integrated.

Original rank 1 demoted to 5-way rank 2 + FLAGGED (std 0.27). Same pattern as 3-way: single-model-risk re-detected. Robust even with more metrics.

→ consensus_5way.json

Boltz-2 affinity pipeline executed (YAML + MSA server + `--method affinity`). 6 of TYK2 top-20 succeeded (14 failed due to MSA rate limit).

Two Boltz-2 metrics point in different directions — affinity_log_ic50 inversely correlates with MolForge, while binding_probability shows strong positive correlation. Confirms the necessity of true multi-model consensus.

→ boltz2_affinity_top20.json

SynFormer analog generation scaled up (top-10: 79 analogs to top-50: 333 analogs).

Expanded pool quality and quantity for licensing. All analogs are synthesis-guaranteed (no post-hoc verification needed).
