25389-94-0 Usage
Description
It has been well known as desirable antibiotics, which shows an obvious curative effect on serious infections caused by gram-negative bacteria such as Escherichia coil, Klebsiella, Proteus, Pneumonia, Enterobacter aerogenes and Shigella. Clinically, this substance is mainly used for infections caused by sensitive bacteria including pulmonary infection, urinary tract infection, biliary tract infection, sepsis, and abdominal cavity infection. For example, the effective antibacterial activity of kanamycin sulfate has been demonstrated by the treatment of acute gonorrheal urethritis in men, showing that a single parenterally administered dose of 2 mg of kanamycin sulfate cured 144 (93%) of 155 men with acute gonorrheal urethritis.1 Moreover, kanamycin sulfate was found to be a valuable drug in the treatment of serious infections in infants and children through an analysis of 140 cases treated during a two-year period.2

Uses
Different sources of media describe the Uses of 25389-94-0 differently. You can refer to the following data:
1. Kanamycin monosulfate, is used as an aminoglycoside antibiotic. Kanamycin can be used as a selection agent in several types of isolation media.Kanamycin sulfate from Streptomyces kanamyceticus has been used in tissue culture media. Kanamycin sulfate can also be used as a selection agent for cells transformed with kanamycin B resistance gene. It is recommended for use in cell culture applications at 100mg/mL.
2. Kanamycin sulfate is an antibacterial agent similar to neomycin.
Definition
A broadspectrum antibiotic.
Manufacturing Process
As described in US Patent 2,931,798, Streptomyces kanamyceticus (K2-J) was
first cultured in shake flasks in the following media: (a) 0.75% meat extract,
0.75% peptone, 0.3% NaCl, with 1.0% of starch, dextrin, maltose, glucose,
lactose, sucrose or glycerol; or (b) 2.0% soybean meal, 0.05% KCl, 0.05%
MgSO4 · 7H2O, 0.5% NaCl, 0.2% NaNO3, with 1.0% of starch, dextrin,
maltose, glucose, lactose, sucrose or glycerol. The initial pH of all media was
adjusted to 7.0. After 24 to 48 hours shaking in some cases the pH decreased
to about 6.0 to 6.8, but from 72 to 120 hours the pH rose and became 7.5 to
8.6. The production of kanamycin was apparent after 48 hours and, depending
on the media; the maximum production was found after 72 to 120 hours.The yield was highest with starch or dextrin, intermediate and about the same
with sucrose, glucose, maltose and lactose and poorest with glycerol.
Kanamycin was produced by media containing soybean meal, peanut meal,
cottonseed meal, corn steep liquor, peptone, yeast extract or meat extract,
with or without sodium nitrate. Commercially available soybean meal was
recognized to be one of the best nitrogen sources. The addition of corn steep
liquor, peptone, yeast extract or nitrate to the soybean meal promoted the
production of kanamycin.The brownish white kanamycin (5 g) was dissolved in 50 ml of 60% aqueous
methanol, insoluble material was removed and to the filtrate 40 ml of 60%
aqueous methanol containing 2,000 mg of ammonium sulfate was added, and
the precipitated kanamycin sulfate was collected, washed with 50 ml of 80%
aqueous methanol, and dried. Thus, 4.5 g of kanamycin sulfate was obtained
as a light brownish powder.
Therapeutic Function
Antibacterial
General Description
Kanamycin sulfate is a broad spectrum aminoglycoside-antibiotic derived from Streptomyces kanamyceticus. It is used as an additive in culture media for the isolation of group D streptococci on Kanamycin Esculin Azide Agar and for selection of transformed plant cells containing the neomycin phosphotransferase on a kanamycin-medium. Kanamycin sulfate can also be used as a selection agent for cells transformed with kanamycin B resistance gene. It is recommended for use in cell culture applications at 2 mL/L.
Biological Activity
soluble in water at 50mg/ml recommend our ultra pure, nuclease free water, ab02123 typically used at 100mg/ml for cell culture protect from moisture store: 2-8°c.
Biochem/physiol Actions
Mode of Action: The product acts by binding to the 70S ribosomal subunit, inhibiting translocation and eliciting miscoding. Mode of Resistance:Aminoglycoside-modifying enzymes (including acetyltransferase, phosphotransferase, nucleotidyltransferase) can alter this antibiotic, preventing its interaction with ribosomes.Antimicrobial spectrum: Kanamycin sulfate is effective against gram-negative and gram-postiive bacteria, and mycoplasma.
Check Digit Verification of cas no
The CAS Registry Mumber 25389-94-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,3,8 and 9 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 25389-94:
(7*2)+(6*5)+(5*3)+(4*8)+(3*9)+(2*9)+(1*4)=140
140 % 10 = 0
So 25389-94-0 is a valid CAS Registry Number.

Mystery solved: Using heterologous expression, the activities of two enzymes exclusively belonging to the kanamycin biosynthetic pathway have been identified in vitro. A distinctive reaction mechanism (see scheme) to produce kanamycin is proposed and the previously unknown catalytic deamination activity of KanJ dioxygenase is uncovered. Copyright
