Polyurea dendrimer folate-targeted nanodelivery of L-buthionine sulfoximine as a tool to tackle ovarian cancer chemoresistance. Recommended basis is Sulfoximine, Bioisosteric. Products is: https://www.ambeed.com/products/50578-18-2.html, 145026-07-9

(2S)-2-Amino-4-(butylsulfonimidoyl)butanoic acid (BD136012) is a building block containing a sulfoximine group. Several CDK and ATR inhibitors have exemplified the utilization of the NH sulfoximine group as abioisostere for a sulfonamide group to overcome the main project hurdles of aqueous solubility, sulfonamide-mediated off-target activity and IP. Moreover, its NH group could be expediently further functionalized through Buchwald-Hartwig coupling reaction and multifarious nucleophilic reactions.. Recommended Products is: 4381-25-3 and 1621962-30-8.

Ovarian cancer is a highly lethal disease, mainly due to chemoresistance. Our previous studies on metabolic remodeling in ovarian cancer have supported that the reliance on glutathione (GSH) bioavailability is a main adaptive metabolic mechanism, also accounting for chemoresistance to conventional therapy based on platinum salts. In this study, we tested the effects of the in vitro inhibition of GSH synthesis on the restoration of ovarian cancer cells sensitivity to carboplatin. GSH synthesis was inhibited by exposing cells to L-buthionine sulfoximine (L-BSO), an inhibitor of ¦Ã-glutamylcysteine ligase (GCL). Given the systemic toxicity of L-BSO, we developed a new formulation using polyurea (PURE) dendrimers nanoparticles (L-BSO@PUREG4-FA2), targeting LBSO delivery in a folate functionalized nanoparticle.
