Gene Information

General description

Ciprofloxacin is a second-generation broad-spectrum fluoroquinolone antibiotic with extensive antimicrobial and pharmacokinetic properties that is widely used to combat bacterial infections. Its chemical name is 1-cyclopropyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid.

Chemical structure: fluoroquinolone

Application

Ciprofloxacin is widely used in clinical practices against Gram-positive and Gram-negative bacteria and the treatment of a broad range of infections, including those of the skin, eyes, urinary tract, lower respiratory tract, gastrointestinal tract, et cetera. It can also be combined with various antimicrobial agents to combat bacterial biofilms as well as multidrug-resistant microorganisms. Its derivatives have been developed to synthesize novel antibacterials with enhanced potency and diverse antimicrobial effects including antibacterial, antifungal, anti-HIV, anti-tumor, and anti-TB properties.

Biochem/physiol Actions

The mechanism of action of Ciprofloxacin is the inhibition of bacterial DNA synthesis by blocking the subunit A of DNA gyrase enzyme as well as by affecting the bacterial cell wall.

Questions

1–10 of 15 Questions  
  1. I am using ciprofloxacin (Product No. 17850) for research and would like to know if it can be dissolved directly in 0.1 M NaOH to prepare a stock solution. Is 0.1 M NaOH a recommended solvent, or could it affect the stability of the compound?

    1 answer
    1. The solubility of this product in NaOH has not been determined. However, other sources report that Ciprofloxacin is soluble at 3 mg/mL in 0.1 N NaOH. This information has not been validated. Note that this material is soluble in DMSO (<1 mg/ml at 25° C), methanol, 0.1N hydrochloric acid (25 mg/ml), and ethanol (<1 mg/ml at 25° C). It is insoluble in water.

      Helpful?

  2. What is the ratio used to dilute ciprofloxacin in saline solution? 0.05 g in 10 ml?

    1 answer
    1. This product has very limited solubility in water, rates of approximately 80 ug/mL are reported in the literature. This material is soluble in 0.1 N HCl at 25 mg/mL. Stock solutions are typically diluted in aqueous buffers or medium. External sources indicate that stock solutions may be diluted with 5% dextrose or normal saline to a concentration of 1 – 2 mg/mL. This information has not been validated.

  3. can we use analytical grade ciprofloxacin in patients

    1 answer
    1. This product is intended for research use only. Unfortunately, there is not a pharmaceutical grade Ciprofloxacin product currently offered. Unless otherwise stated this product is not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals.

  4. is this the anhydrous form of ciprofloxacin?

    1 answer
    1. This product is not tested for moisture content.

      Helpful?

  5. Is Ciprofloxacin HCL available and is it USP grade?

    1 answer
    1. Product 17850 has a molecular formula of C17H18FN3O3. The form of the chemical being searched for would have a molecular formula of C17H18FN3O3.HCL,H2O. There is Ciprofloxacin HCL.H2O but only in very small quantities as a secondary pharmaceutical standard, with the catalog number PHR1044. Regarding the question about whether the products are USP grade, the answer is no. Both products are labeled as strictly for Research Use Only and, as such, are not suitable for human use.
