Physical and Chemical Properties | Cilastatin SodiuIn: C16H25N2NaO5S. [86109-83-1]. Off-white to off-white amorphous solid, hygroscopic. Very soluble in water or methanol. Pka = 2.0,pKa = 24.4,pKa = 39.2. |
Use | Renal peptidase inhibitors. It can be used in combination with carbapenem antibiotic imine. Because of its specific inhibition of renal peptidase, the latter is protected from the degradation of renal peptidase, and the activity of imine ligand is improved. The mixture of cilastatin sodium and imine ligand (1:1) was Tienan (Primaxin). |
In vivo study | In a mouse model (female mice, strain CD-1, 20 g) of systemic infection, Imipenem plus Cilastatin can protect mice from S. aureus , E. coli , and P. aeruginosa infection. |

production method | the reaction of ethyl 2, 2-diethoxyacetate and 1, 3-propanedithiol gave 1, ethyl 3-dithiane-2-carboxylate, yield 69.4%. It is then reacted with 1, 5-dibromopentane in the presence of sodium hydride to give ethyl 2-(5-bromopentyl)-1, 3-dithiane-2-carboxylate. This is followed by reaction with brominated succinimide (NBS) to give ethyl 7-bromo-2-oxoheptanoate. Acidic hydrolysis gave 7-bromo-2-oxoheptanoic acid in 69% yield (based on 1, 3-dithiane-2-carboxylic acid ethyl ester). 2, 2-dimethyl-1, 3-propanediol was esterified with P-Toluenesulfonyl chloride to form bis-p-toluenesulfonate in a yield of 94.3%. Under the action of potassium cyanide, 2, 2-dimethylcyclopropane carbonitrile was obtained by cyclization in a yield of 64.9%. Alkaline hydrolysis of aqueous potassium hydroxide solution, Racemic 2, 2-dimethylcyclopropane carboxylic acid was obtained in almost quantitative yield. The racemate was resolved with L-quinine to give the pure (S) configuration in 14.1% yield. It is then reacted with N-trifluoroacetoxysuccinimide to give (+)-N-[(2,2-dimethylcyclopropane) formyloxy] succinimide in a yield of 90.5%. The imine compound is an active ester compound with high reactivity, and (+)-(S)-2, 2-dimethylcyclopropanecarboxamide is obtained by aminolysis in a yield of 83%. The product of 7-bromo-2-oxoheptanoic acid and (+)-(S)-2, 2-dimethylcyclopropanecarboxamide refluxed in toluene (Yield 25%) further reaction with L-cystine gave cilastatin in a yield of 63% [α]D23 +18.0 °(C = 0.54, methanol). |
