    Abstract: Provided herein are block copolymers comprising a hydrophilic polymer segment and a hydrophobic polymer segment, wherein the hydrophilic polymer segment comprises a polymer selected from the group consisting of: poly(ethylene oxide) (PEO), poly(methacrylate phosphatidyl choline) (MPC), and polyvinylpyrrolidone (PVP), wherein the hydrophobic polymer segment comprises wherein R′ is —H or —CH3, wherein R is —NR1R2, wherein R1 and R2 are alkyl groups, wherein R1 and R2 are the same or different, wherein R1 and R2 together have from 5 to 16 carbons, wherein R1 and R2 may optionally join to form a ring, wherein n is 1 to about 10, and wherein x is about 20 to about 200 in total. Also provided are pH-sensitive micelle compositions for therapeutic and diagnostic applications.

    Abstract: Embodiments of the present disclosure pertain to formulations for cancer treatment that include a particle loaded with diethylstilbestrol (DES) and a pharmaceutically acceptable carrier. The pharmaceutically acceptable carrier may also be loaded into the particle. The formulations may also include a stabilizer that is also loaded into the particle. The particles may be dispersed in an aqueous solution to form a nanosuspension that is adapted for subcutaneous administration and sustained release of DES. Additional embodiments pertain to methods of treating cancer in a subject by administering to the subject a formulation of the present disclosure. The subject may be a human suffering from prostate cancer. The administration of the formulations to the subject may bypass or minimize first pass metabolism. The administration may also minimize hepatic exposure of DES. Additional embodiments pertain to methods of making the formulations of the present disclosure by loading a particle with DES.
