Headquartered in Xiangyang, our campus integrates solid-phase peptide synthesis, downstream isolation, and analytical release under one quality system. The site is purpose-built for milligram-to-kilogram research-grade output, with environmental controls calibrated for sensitive sequences and copper-bound complexes.
Escrever o tempo na escala dos átomos
Peptídeos são cadeias curtas de aminoácidos unidas por ligações peptídicas precisas. São a linguagem com que as células coordenam metabolismo, reparo e envelhecimento. Na Xiangyang Lizhi aplicamos rigor molecular à biologia do tempo.
Síntese em fase sólida
SPPS automatizada com química Fmoc para sequências de até 60+ resíduos com rendimento reprodutível.
Purificação cromatográfica
RP-HPLC preparativo e troca iônica. Cromatograma independente por lote.
Caracterização estrutural
Confirmação cruzada tripla por MALDI-TOF, LC-MS e RMN.
Estudos de estabilidade
Estabilidade acelerada e de longo prazo segundo diretrizes ICH, preservando o prazo de validade.
Nitrogen, chilled water, and inert-gas lines feed the reaction hall directly. Continuous utilities are what allow Fmoc deprotection and coupling cycles to run without drift in temperature or atmosphere — the invisible infrastructure behind every peptide bond formed on site.
Solvent is stripped from a synthesis intermediate on a rotary evaporator under reduced pressure. This is the unglamorous middle of the route: each crude peptide is concentrated, exchanged, and prepared for cleavage before it ever sees a purification column.
From sterile bulk to sealed vial, without contact with the operator.
Filtered peptide solution is metered into siliconised borosilicate vials inside a Grade A air stream. Stopper insertion and crimp closure happen in line, so the molecule moves from compounding tank to sealed primary container without an open transfer step. What enters the lyophiliser is what we synthesised — nothing added, nothing lost.

Moléculas para pesquisa
Dezessete insumos peptídicos representativos para pesquisa. Cada molécula traz informação estrutural, mecanismo e direção de pesquisa.
A reversed-phase HPLC column resolves the target peptide from synthesis-related impurities; the same column data later anchors the certificate of analysis. Beside it sits the freeze-dryer, where the purified solution is taken below 0.05 mbar and slowly sublimed into a porous lyophilised cake stable for years at -20 °C.
Vials emerge from the lyophiliser onto a stainless tray for 100% visual inspection: cake structure, fill height, closure seating, and absence of particulates. Only vials that pass this check are crimped, labelled, and assigned a release batch number — every other vial is destroyed.
O tempo é irreversível. Mas pode ser compreendido.
Acreditamos que envelhecer é um processo biológico que pode ser estudado. A Xiangyang Lizhi coloca o rigor químico nas mãos de instituições acadêmicas, farmacêuticas de P&D e laboratórios pré-clínicos, para que cada molécula seja uma ferramenta de compreensão da vida.

Inside the reaction hall.
A technician verifies temperature and stirring on a jacketed stainless reactor during a peptide-coupling step. Every cycle is logged against the batch record: reagent lot, equivalents, time, and in-process control. Nothing about a peptide bond is improvised here.
A single vial. A single sequence.
The porous white cake at the bottom of the vial is the peptide itself, frozen out of solution and dried under vacuum until only the molecule remains. Stable, dose-accurate, and ready to be reconstituted in bacteriostatic water under research conditions — exactly as it left our analytical release.

Sediada em Xiangyang, Hubei. Nosso nome vem das milenares lichieiras da cidade, símbolo do presente da natureza e da paciência do tempo. Focamos em pesquisa de peptídeos bioativos e fornecimento de insumos para a comunidade global de longevidade e medicina regenerativa.
Analysts overlay the current batch chromatogram against the reference standard. Identity, retention time and main-peak area are confirmed before the batch number is ever issued. This is the last gate between synthesis and the certificate of analysis attached to your vial.
Sensitive reagents and protected amino acids are weighed and transferred under extraction. The same gloved hands that build a tripeptide today have built thousands before it; that continuity is the difference between a research-grade sequence and a batch.
