P21 is a nootropic peptide targeting improved neurogenesis. In animal studies, P21 has been shown to boost levels of BDNF (brain-derived neurotrophic factor), thus promoting neurogenesis (nerve growth) and inhibiting the formation of Amyloid plaques and Tau proteins seen in Alzheimer's disease. BDNF has been linked not just to enhanced neurogenesis, but to the down regulation of certain enzyme responsible for tau and amyloid plaque formation in Alzheimer's brains. P21 has been shown to improve cognition in animal models.
P21 is a modified, synthetic mimetic of CNTF. CNTF is a naturally occurring protein mediator of neuron growth in humans. The effects of CNTF have primarily been studied in the nervous system, though there are receptors for the peptide in other locations throughout the body (e.g. bone). It has been shown to promote neurotransmitter synthesis and neurite outgrowth. It also protects neurons and their supporting cells against inflammatory attacks. In addition to its neurotrophic effects, CNTF is known to increase satiety and thus reduce food intake.
CNTF and cerebrolysin are not the same molecule. P21 and cerebrolysin are not the same either_ If is discussed below and contrasted with P21.
A recombinant version of CNTF was developed under the brand name Axokine. It was tested as a treatment for amyotrophic lateral sclerosis and is currently not sold. Interestingly, the body is quick to generate antibodies against Axokine, suggesting that there may be a potential for administering P21 and exogenous CNTF together in some settings, thus boosting CNTF levels while keeping antibody activity to a minimum.

Zhaobo Bio acquired early mastery of development and manufacturing of peptides, the short chain amino acids linked by peptide bonds that have enabled new generations of small molecule drugs that closely mimic the body's natural pathways.
Now Zhaobo Bio possesses first-class capabilities to manufacture peptides at industrial scale and in full compliance with the strictest Good Manufacturing Practice (GMP) standards.
Upstream peptide synthesis
Zhaobo Bio production plants are endowed with state-of-the-art equipment for solvent supply, peptide synthesis, purification and isolation of active ingredients and intermediates. All equipment and containment is GMP qualified and cleaning validated. Overlapping capacities and sizes of different equipment trains facilitate a smooth scale-up for increases in demand within the product life cycle.
Downstream purification and isolation of peptides
Zhaobo Bio is committed to the systematic expansion and modernization of its purification equipment in order to ensure the efficient production of ever-increasing amounts of bulk peptide pharmaceuticals.
It uses sophisticated methods for large scale purification campaigns such as preparative high performance liquid chromatography (HPLC), ion exchange (IEX), size-exclusion chromatography (SEC), and ultra-filtration (UF/TFF). The equipment in place permits highly efficient or even continuous manufacturing of extremely pure products up to multi-kg quantities per lot.
For preparative HPLC, dynamic axial compression (DAC) stainless steel columns of up to 60 cm diameter both in batch and continuous mode are packed with the appropriate high performance silica separation phase. For low-pressure chromatography columns up to 80 cm diameter are available. Solvent delivery is ensured from eluent tank farms and containers.
The control of microbiological contamination is a prerequisite for API manufacturing. Class D (ISO 8) and C (ISO 7) clean rooms are supplied via HEPA-filtered, temperature and humidity controlled air, down-flow booths are used for minimizing microbial contamination and protecting operators. Highly active pharmaceutical ingredients are handled in integrated safety workbenches or flexible isolators reaching OEB level 4 (1-10 µg/m3).
Predefined physicochemical properties of the API can only be achieved by a carefully controlled isolation process. Besides precipitation and crystallization, lyophilization of intermediates and final API is a standard unit operation. LaixingPharma have multiple lyophilizers in different sizes (up to 300 liters) located in clean rooms.
