2-Amino-1,3-propanediol (2-APD, also known as serinol) is a high-value-added chemical that is used as a building block for the synthesis of a variety of compounds, including drugs to treat type 2 diabetes mellitus, the antibiotic chloramphenicol, immune multiple sclerosis, and a new generation of nonionic X-ray contrast agents.
화학적 성질
white to off-white adhering crystalline powder
용도
2-Amino-1,3-propanediol is used as an intermediate in several chemical applications and also useful for serinol and some of its derivatives.
제조 방법
Add 20% 2-nitro-1,3-propanediol methanol solution (1250 g) to 5% palladium/carbon 3.5 g. Hydrogen (70 L, pressure 3MPa) was continuously introduced and reacted at 75°C for 5 hours to obtain serine alcohol solution. The serine alcohol solution is pumped into a high vacuum distillation vessel, vacuumed to 40 pa, and methanol is distilled for reuse. Yield = 97.2%.
Biosynthesis
Currently, the manufacture of 2-Amino-1,3-propanediol (2-APD) predominantly relies on chemical processes by utilizing fossil fuel-derived and highly explosive raw materials. In addition to chemical synthesis, its synthesis can also rely on biosynthesis. Luo et al. established an artificial biosynthetic pathway for converting glucose to 2-APD in a metabolically engineered Escherichia coli. This artificial pathway employs an engineered heterogeneous aminotransferase RtxA for diverting dihydroxyacetone phosphate (DHAP) to generate 2-APD phosphate and an endogenous phosphatase for converting it into the target product 2-APD. 2-APD-P is 2-amino-1,3-propanediol phosphate[1].
일반 설명
Serinol activates toxin production in the attenuated cultures of Helminthosporiumsacchari. Preparation of polyesters derived from serinol is reported.
