1-Deoxymannojirimycin HCl

1-甘露糖野尻霉素

Potent and specific inhibitor of α-mannosidase I. It is active against the Golgi isoform (GMI) of the enzyme and blocks carbohydrate branch elongation from immature to complex and hybrid N-glycans. Its anti-viral activity against HIV-1 is characterized by the alteration of N-glycan pattern and shift to high-mannose glycans on viral glycoprotein gp120, resulting in decreased infectivity of newly synthesized virions.

1-Deoxymannojirimycin hydrochloride (DMJ-HCl) is a potent inhibitor of alpha-mannosidase, which is an essential enzyme involved in glycoprotein metabolism. This compound is found naturally in mulberry leaves, and its chemical structure is similar to that of glucose. DMJ-HCl has been studied for its potential therapeutic applications in various diseases, including diabetes, cancer, viral infections, and lysosomal storage disorders.

Physical and Chemical Properties

DMJ-HCl is a white crystalline powder with a molecular weight of 277.68 g/mol. It is soluble in water and ethanol but insoluble in chloroform and ether. DMJ-HCl has a melting point of 224-226°C and a pKa value of 8.4. Its chemical structure is shown in Figure 1.

Synthesis and Characterization

DMJ-HCl can be synthesized through various methods, including chemical synthesis, microbial fermentation, and extraction from natural sources. Chemical synthesis involves the reaction between 2,3,4,6-tetra-O-acetyl-D-glucopyranosyl bromide and 2,5-diamino-1,4-benzoquinone in the presence of a base. Microbial fermentation involves the use of microorganisms such as Streptomyces and Bacillus to produce DMJ-HCl. Extraction from natural sources involves the use of mulberry leaves, which are a rich source of DMJ-HCl.

Analytical Methods

Various analytical methods have been developed to quantify and analyze DMJ-HCl in different samples, including pharmaceuticals, biological fluids, and plant extracts. High-performance liquid chromatography (HPLC) with UV detection is the most commonly used method for the analysis of DMJ-HCl. Other methods, such as gas chromatography-mass spectrometry (GC-MS), capillary electrophoresis (CE), and nuclear magnetic resonance (NMR), have also been used for DMJ-HCl analysis.

Biological Properties

DMJ-HCl has been shown to possess various biological properties, including anti-diabetic, anti-cancer, anti-viral, and neuroprotective activities. DMJ-HCl acts by inhibiting alpha-mannosidase, which is involved in the metabolism of glycoproteins. This inhibition leads to the accumulation of glycoproteins in the lysosomes, which results in cellular dysfunction and death in cancer cells and viruses.

Toxicity and Safety in Scientific Experiments

DMJ-HCl has been found to be safe and well-tolerated in both animal and human studies. It has been shown to have low toxicity and no significant adverse effects at therapeutic doses. However, some studies have reported mild gastrointestinal disturbances, such as nausea and vomiting, at higher doses.

Applications in Scientific Experiments

DMJ-HCl has been extensively studied for its potential therapeutic applications in various diseases, including diabetes, cancer, viral infections, and lysosomal storage disorders. DMJ-HCl has been shown to improve glucose uptake, insulin sensitivity, and glycemic control in diabetic models. DMJ-HCl has also been shown to inhibit cancer cell growth and induce apoptosis in vitro and in vivo. DMJ-HCl has been shown to inhibit the replication of various viruses, including HIV, influenza, and dengue. DMJ-HCl has also been studied for its potential therapeutic applications in lysosomal storage disorders, such as Pompe disease and Fabry disease.

Current State of Research

DMJ-HCl is currently under investigation for its therapeutic potential in various diseases, including diabetes, cancer, viral infections, and lysosomal storage disorders. Several preclinical and clinical trials are underway to evaluate the safety and efficacy of DMJ-HCl in these diseases.

Potential Implications in Various Fields of Research and Industry
