Pharmaceutical Peptides
Pharmaceutical peptides are sequence-defined, synthetic peptide active pharmaceutical ingredients (APIs) used as drugs or drug intermediates for metabolic, oncologic, cardiovascular, anti-infective and rare-disease indications — combining the specificity of biologics with the manufacturability and storage stability of small molecules.

What Are Pharmaceutical Peptides?
Pharmaceutical peptides are chemically synthesized peptide APIs manufactured under defined quality systems for use as human or veterinary drugs. They sit between small molecules and biologics: high target specificity and low off-target toxicity, predictable metabolism, and scalable SPPS/fragment-condensation production routes compared with recombinant expression.
Common Categories
Metabolic (insulin, GLP-1 analogs, somatostatin), oncologic (BNCT carriers, tumor-targeting ligands), cardiovascular (anti-thrombotic, RGD anti-platelet), anti-infective (defensins, viral-entry blockers), reproductive/endocrine (oxytocin, GnRH analogs) and rare-disease orphan peptides.
Manufacturing & QC
Pharmaceutical-grade production combines Fmoc SPPS (or fragment condensation for long chains) with RP-HPLC / IEX purification, counter-ion exchange (TFA → acetate / chloride), ICH Q7 documentation, stability-indicating methods, impurity profiling, and endotoxin / bioburden control. CMC documentation supports IND/NDA filings.

Pharmaceutical Peptides — Frequently Asked Questions
What is a pharmaceutical peptide exactly?
A pharmaceutical peptide is a synthetic peptide used as an active pharmaceutical ingredient (API) in a drug product. It is characterized by a defined amino-acid sequence, a defined impurity profile, and manufactured under a pharmaceutical quality system (ICH Q7/Q11) suitable for human use — distinct from research peptides used only in early-stage discovery.
Which therapeutic areas do you support?
Metabolic (insulin, GLP-1, dual agonists), oncologic (tumor-targeting ligands, BNCT carriers), cardiovascular (anti-thrombotic peptides), anti-infective (defensins, viral-entry blockers), reproductive / endocrine (oxytocin, GnRH analogs), and rare-disease / orphan peptide APIs — covering both sequence supply and CMC documentation.
Which synthesis routes do you use?
Fmoc-SPPS is the default workhorse (up to ~50 residues). Longer or difficult sequences switch to fragment condensation with native chemical ligation, or enzymatic coupling. Microwave-assisted synthesis and pseudo-dilution strategies are used for cyclic, stapled, or aggregation-prone targets.
What modification catalog is available?
Standard catalog: N-terminal acetylation / pyroglutamate / fatty-acid conjugation (C8, C12, C16), C-terminal amidation, head-to-tail or side-chain cyclization, disulfide bond formation (1–4 bridges), PEGylation (5–40 kDa), phosphorylation (pSer/pThr/pTyr), glycosylation (GlcNAc, Man), D-amino-acid substitution, and fluorescent/affinity labels.
What purity and regulatory grade can you deliver?
Research grade (≥95% HPLC), preclinical grade (≥98% with full CoA and impurity profile), and cGMP / CMC support (≥99% with ICH-stability data, endotoxin, bioburden, residual solvent, counter-ion and metal testing). Method transfer and process-validation support are available.
How do I start a pharmaceutical-peptide project?
Send the target sequence (or analog reference), desired scale, target grade, and intended indication to sonytbio@163.com. A peptide scientist replies within one business day with feasibility, route recommendation (SPPS / fragment condensation / hybrid), timeline, and a quotation; CMC documentation can be added for regulatory filings.
