Storage method

This product should be sealed and stored dry at 4°C. Valid for 2 and a half years.

Synthesis method

First, the side chain carboxylic acid of D(-)-phenylglycine is treated with the chlorinating agent PCI5. It is made into acid chloride and then condensed with 6-APA. Add acetone and water to the reaction tank, add 6-APA when the temperature reaches -5–10°C, and add phenylglycyl chloride hydrochloride. After 0.5 hours of reaction, adjust the pH to 3.5 with 10% sodium hydroxide. The reactants were extracted with toluene. Take the aqueous layer and adjust the pH value to about 3.0 with 10% ammonia water. Decolorize with activated carbon and filter. The filtrate was then adjusted with ammonia water to make the pH 4.8. Leave to stand, then filter, wash with acetone, and vacuum dry below 40°C to obtain the product.

Purpose

For molecular biology and tissue culture. Broad-spectrum penicillin can be semi-synthesized. This product is not resistant to enzymes, stable to acid, and has low toxicity. It has inhibitory effects on both Gram-negative bacteria and Gram-positive bacteria, and has a strong effect on Escherichia coli, influenzae, Salmonella, Shigella and some Proteus.
