Description
Lasalocid is an ionophore antibiotic isolated from Streptomyces lasaliensis, characterized by its potent antibacterial activity and the ability to form neutral complexes with monovalent and divalent cations, as well as larger organic cations like protonated dopamine. It is used in veterinary practice as a coccidiostat for gastrointestinal parasites and has demonstrated cytotoxicity targeting cell metabolism.
Uses
Used in Veterinary Medicine:
Lasalocid is used as a coccidiostat for treating gastrointestinal parasites in animals. It is effective in controlling coccidiosis, a disease caused by protozoan parasites of the genus Eimeria, which can lead to significant economic losses in poultry farming.
Used in Anticancer Applications:
Lasalocid functions as an anticancer supplement agent, particularly for treating brain tumors. It comprises a polyether antibiotic that inhibits mitochondrial GPD2 activity, leading to anti-proliferative effects on cancer cells.
Used in Pharmaceutical Research:
Lasalocid's unique ability to transport ions through apolar phases, including lipid bilayer membranes, makes it a valuable tool in pharmaceutical research. Its properties are being studied for potential applications in drug delivery and the development of new therapeutic agents.
Brand Names:
Avatec [as sodium] [Veterinary] (Hoffmann-LaRoche)

in vitro
a previous study was conducted to compare effects of the combined use of lasalocid and silybin in chicken hepatoma cells and rat myoblasts cell lines cultures. results showed that in all performed tests, the lowest lasalocid ec50-values were obtained for chicken hepatocytes. in the rat myoblasts cultures, the lowest lasalocid ec50-values were found. moreover, a lack of silybin cytotoxic effect was proven for the studied cell lines. an interaction between both substances resulted in a great decrease of lasalocid cytotoxicity. the isobolograms and combination index indicated a significant antagonistic nature of silybin effect in the course of lasalocid cytotoxicity [1].
in vivo
in a animal study, chickens 8 or 9 days old were given a completely purified crystalline amino acid diet. results showed that the requirement for sulphur-containing amino acids (saa) was neither increased nor decreased by lasalocid at 125 mg/kg diet. moreover, lasalocid could cause a significant increase in gain and gain/feed intake when added to diets that were deficient in saa, but it led to a marked decrease in performance when added to diets adequate in saa. in addition, at moderate levels of saa deficiency, lasalocid at 125 mg/kg could neither increase nor decrease the rate and efficiency of weight gain and there was no evidence of the saa x lasalocid interaction when lasalocid was given in a typical starter diet of maize and soya [2].

Check Digit Verification of cas no
The CAS Registry Mumber 25999-31-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,9,9 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 25999-31:
(7*2)+(6*5)+(5*9)+(4*9)+(3*9)+(2*3)+(1*1)=159
159 % 10 = 9
So 25999-31-9 is a valid CAS Registry Number.

Two new complexes of the ionophore antibiotic Lasalocid acid (LAS) with phenylamine (PhA) and butylamine (BuA) were synthesized and their molecular structures were studied using single crystal X-ray diffraction and spectroscopic methods. In the solid state both amines are protonated and all NH3+ protons are hydrogen bonded to etheric, hydroxyl and carboxylic oxygen atoms of the LAS anion. In chloroform solutions the structure observed in the crystal of LAS-BuA complex is preserved and an equilibrium between the LAS-PhA complex and dissociated Lasalocid acid and phenylamine is observed. In vitro antimicrobial tests of the complexes showed a significant activity towards some strains of Gram-positive bacteria. For the first time Lasalocid acid and its complexes with amines were tested in vitro for cytotoxic activity against human cancer cell lines: A-549 (lung), MCF-7 (breast), HT-29 (colon) and mouse cancer cell line P-388 (leukemia). We found that LAS and its complexes are strong cytotoxic agents towards all tested cell lines. The cytostatic activity of the compounds studied is greater than that of cisplatin, indicating that Lasalocid and its complexes are promising candidates for new anticancer drugs.
