  An Uncharged Oxetanyl Sulfoxide as a Covalent Modifier for Improving Aqueous Solubility

  摘要：

  Low aqueous solubility is a common challenge in drug discovery and development and can lead to inconclusive biological assay results. Attaching small, polar groups that do not interfere with the bioactivity of the pharmacophore often improves solubility, but there is a dearth of viable neutral moieties available for this purpose. We have modified several poorly soluble drugs or drug candidates with the oxetanyl sulfoxide moiety of the DMSO analog MMS-350 and noted in most cases a moderate to large improvement of aqueous solubility. Furthermore, the membrane permeability of a test sample was enhanced compared to the parent compound.

  Large-Scale Asymmetric Synthesis of the Bioprotective Agent JP4-039 and Analogs

  摘要：

  JP4-039 is a novel nitroxide conjugate capable of crossing lipid bilayer membranes and scavenging reactive oxygen species (ROS). An efficient and scalable one-pot hydrozirconation-transmetalation-imine addition methodology has been developed for its asymmetric preparation. Furthermore, this versatile methodology allows for the synthesis of cyclopropyl and fluorinated analogs of the parent lead structure.

  JP4-039 is a lead structure in a series of nitroxide conjugates that are capable of accumulating in mitochondria and scavenging reactive oxygen species (ROS). To explore structure–activity relationships (SAR), new analogs with variable nitroxide moieties were prepared. Furthermore, fluorophore-tagged analogs were synthesized and provided the opportunity for visualization in mitochondria. All analogs were tested for radioprotective and radiomitigative effects in 32Dcl3 cells.
