Four integrated tools. One unified research environment.
Interactive Builder
Build a peptide residue by residue and watch mass, hydropathy, and net charge update live. Clear chemistry challenges to earn XP — a hands-on way to learn sequence design.
AI Assistant
Ask in plain language and get citation-backed answers — the agent cross-references PubChem structures, ClinicalTrials.gov studies, and mechanisms into structured evidence.
Trial Intelligence
Real-time surveillance of peptide-based clinical trials across ClinicalTrials.gov and WHO ICTRP. Surface recruitment trends, endpoint shifts, and competitive pipeline movements.
PubChem Explorer
Search PubChem for peptides and small molecules. Inspect 2D structures, molecular formulae, and weights, then jump straight to the underlying NIH compound record for deeper review.

Query PubChem for compounds, ClinicalTrials.gov for studies, or ask the research agent in natural language.
Cross-reference structures, sponsors, phases, and mechanisms — surfaced as structured evidence with primary-source links.
Identify whitespace, candidate analogs, and emerging trial signals to guide your next experimental hypothesis.
Each coupling step is 30–60 minutes. A 40-residue chain takes days on the synthesizer, then HPLC, then lyophilization. The wait is the COA. Vetted suppliers, third-party certificates, per-mg pricing — worth it when it arrives.
