    Lasalocid Sodium

    $106.00 - $312.50

    Lasalocid Sodium is the salt form of Lasalocid, a carboxylic polyether ionophore. The compound has anticancer properties and antibacterial activity. Lasalocid is isolated from Streptomyces lasaliensis, first reported in 1951. It is also known as a coccidiostat; developed for the treatment of coccidia in animals, it stops coccidia from reproducing.

    Lasalocid is a mixture of several closely related homologues: A, B, C, D and E. Lasalocid Sodium is primarily made up of Lasalocid A, with the other analogs (B, C, D, E) making up no more than 10% of the total weight of the active substance.

    Lasalocid Sodium is soluble in ethanol, methanol, DMF and DMSO. It has limited water solubility.

    Mechanism of Action

    As an ionophore, the compound can increase the permeability of biological (or artificial) lipid membranes to specific ions. Lasalocid Sodium is an ionophore that can form complexes with cations and transport through lipid membranes. It can also transport larger organic cations.

    In cancer researchstudies, researchers found lasalocid induces autophagy through microtubule-associated protein 1 light chain 3 (LC-3)-II conversion. The autophagic properties were mediated by production of reactive oxygen species (ROS), confirmed by using a ROS inhibitor.

    Spectrum Lasalocid Sodium is effective against Gram-positive bacteria and protozoa. Examples of Gram-positive bacteria that are sensitive to the compound are Fusobacterium, Bifidobacterium, Eubacterium, Clostridium, and Lactobacillus.
