Nemifitide (INN-00835) is a novel antidepressant drug with a pentapeptide structure similar to that of melanocyte-inhibiting factor (MIF-1) and the amino acid sequence 4-F-Phe-4-OH-Pro-Arg-Gly-Trp-NH2. It is under development for the treatment of major depressive disorder. It has been given to over 430 people over the course of 12 clinical trials throughout a little over the past decade and has reached Phase III studies, but has not yet been approved for marketing in any country.
Nemifitide has shown mixed efficacy in alleviating depressive symptoms, but in the cases in which it has worked it has proven to have a rapid onset of action (~5-7 days), few to no side effects, and an excellent safety profile. However, it is inactive orally and must be administered via subcutaneous injection. Remarkably, despite having a very short half-life of only 15-30 minutes, in most or all studies assessing its efficacy nemifitide has been administered merely once daily via the subcutaneous route and yet is effective for depression.
The mechanism of action of nemifitide is unclear, but since MIF-1 has been demonstrated to have similar antidepressant effects it may act in an analogous manner. Possibly of interest however is that nemifitide binds to several receptors including 5-HT2A (where it has been shown to act as an antagonist), NPY1, bombesin, and MC4 and MC5, though at only micromolar concentrations. Whether any of these relatively weak actions are of any clinical significance is unclear.

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.
