Description
Sinomenine is a morphinan-type alkaloid from Sinomenium acutum(青藤, “Qing-teng”), traditionally used in TCM for “wind-damp bi-syndrome” (joint pain, stiffness). The HCl salt (CAS 6080-33-7) is the commercial pharma form — water-soluble, ChP-monographed, deployed as injectable powder & oral tablets for rheumatoid arthritis (RA), osteoarthritis (OA), and adjunctive analgesia in the CN/SEA pharma channel.
Literature bioactivity clusters (buyer search hooks):
- Anti-arthritic & Analgesic – suppresses TNF-α, IL-1β, IL-6, MMPs in RA models; microglia-modulating in some neuroinflammation assays (light link to Huperzine A neuro line)
- Immunomodulatory – T/B-cell modulation at higher exposures, literature-level
- Osteoclast/osteoblast balance – bone-remodeling signal (secondary to RA/OA use-case)
Four commercial buckets:
- Pharma API – ChP RA/OA/Analgesic (main): ChP “盐酸青藤碱” injectable + tablet, CN hospital channel steady; SEA/EMA-route export inquiry growing. Search: “sinomenine hydrochloride API”, “盐酸青藤碱 manufacturer”, “sinomenine RA China pharma”.
- Arthritis & Inflammation R&D: CRO/CDMO bulk 98%+ for RA/OA pipeline adjunct, analgesic comparator, microglia/neuro-inflammation tangential (stacks lightly with Huperzine A 102518-79-6 + Icaritin 118525-40-9 in “neuro-inflam / brain-aging” R&D discussions).
- TCM Export Brand: “Qing-teng / Sinomenium acutum” heritage positioning for CN-export TCM brands (usually as part of a “TCM-origin alkaloid API” cluster: berberine, tetrandrine, sinomenine).
- Reference Standard / R&D: 98%+ HPLC for Sinomeniumextract QC, stability, formulation pilot.
Applications

Pharma API (ChP) – injectable powder, tablets; RA rheumatoid arthritis, OA osteoarthritis, adjunctive analgesia; CN hospital channel + SEA export
Arthritis & Inflammation R&D – CRO/CDMO bulk 98%+; RA/OA pipeline, analgesic comparator, cytokine (TNF-α/IL-1β/IL-6) modulation literature
TCM-Derived Alkaloid Cluster – “Qing-teng” heritage; often procured alongside Berberine, Tetrandrine, etc. for TCM-export API baskets
Reference Standard (≥98% HPLC) – Sinomeniumextract QC, sinomenine assay methodology
Upstream link – buyers often also check free base Sinomenine CAS 115-53-7 (R&D/standard); Taima cross-links
