Chemical Similarity Search
Goal
To programmatically find chemical analogs, alternative precursors, and structurally similar compounds for a given target molecule using PubChem's "fastsimilarity_2d" endpoint. The skill retrieves lists of similar compounds ranked by sequence alignment of their 2D molecular fingerprints, providing CIDs, molecular weights, formulas, and SMILES strings.
Instructions
1. Search by SMILES String
Search for similar compounds by providing the canonical or isomeric SMILES.
Adjust the --threshold (similarity cutoff 0-100, default is 95) to widen or narrow the search radius. Higher threshold equals higher similarity.
Adjust --max_records to limit the output length.
# Env: base-agent
python .agents/skills/chem-similarity-search/scripts/similarity_search.py \
--smiles "CC(=O)Oc1ccccc1C(=O)O" \
--threshold 95 \
--max_records 5 \
--outdir research/aspirin_similar \
--output aspirin_similar.json
2. Search by PubChem CID
Search directly using an exact compound's CID. This avoids translation steps for SMILES parsing.
# Env: base-agent
python .agents/skills/chem-similarity-search/scripts/similarity_search.py \
--cid 2244 \
--threshold 90 \
--max_records 10 \
--outdir research/aspirin_similar \
--output cid_2244_similar.json
Examples
We can test extracting highly similar analogs (Threshold 95) for Aspirin (CID: 2244 or SMILES: CC(=O)Oc1ccccc1C(=O)O).
# Env: base-agent
python .agents/skills/chem-similarity-search/scripts/similarity_search.py \
--cid 2244 \
--threshold 95 \
--max_records 5 \
--outdir .agents/skills/chem-similarity-search/examples/aspirin_analogs \
--output aspirin_analogs.json
Constraints
- Rate Limiting: PubChem PUG REST API enforces per-user throttling limits. Heavy bursts will result in
HTTP 503 Server Busyerrors. The script implements an exponential backoff retry mechanism. - 2D Similarity: Uses exact structural bit-vector fingerprints. Stereochemical and 3D properties do not strongly affect the score.
- Network: Internet access is required.

Tinjau sebelum memasang: Hindari pemasangan otomatis
Lisensi: MIT
- Dependency or permission surface needs review
- Permission surface may require sandboxing
- The SKILL.md excerpt shows an incomplete line in the script (e.g., 'elif' with no following code), but this is likely due to truncation in the provided excerpt and not a real issue.
- Quality score needs review

Daftar alat adalah petunjuk metadata, bukan kompatibilitas teruji. Prompt adalah saran.
Mulai dengan tugas kecil
- 1Baca sumber dan pastikan masukan, keluaran, dependensi, serta izin.
- 2Minta rencana dari agent. Setujui pengaturan dan biaya sebelum uji terisolasi.
- 3Periksa hasil dan berkas yang berubah. Laporkan hanya yang dijalankan dan simpan revisi sumber.
Periksa dependensi, kunci API, dan biaya layanan pihak ketiga pada sumber. Repositori publik tidak berarti semua layanan gratis.
