  • Publication number: 20140356417
    Abstract: Drag derivatives are provided herein which are suitable for loading into liposomal nanoparticle carriers. In some preferred aspects, the derivatives comprise a poorly water-soluble drag derivatized with a weak-base moiety that facilitates active loading of the drag through a LN transmembrane pH or ion gradient into the aqueous interior of the LN. The weak-base moiety can optionally comprise a lipophilic domain that facilitates active loading of the drag to the inner monolayer of the liposomal membrane. Advantageously, LN formulations of the drag derivatives exhibit improved solubility, reduced toxicity, enhanced efficacy, and/or other benefits relative to the corresponding free drags.

  • Patent number: 8835435
    Abstract: Novel compounds selected from 2-(3-aminoaryl)amino-4-aryl-thiazoles of formula (I) that selectively modulate, regulate, and/or inhibit signal transductions mediated by certain native and/or mutant tyrosine kinases implicated in a variety of human and animal diseases such as cell proliferative metabolic, allergic and degenerative disorders. More particularly, these compounds are potent and selective c-kit inhibitors.
