The present invention describes methods and compositions for improving the therapeutic efficacy of therapeutic agents previously limited by suboptimal therapeutic performance by either improving efficacy as monotherapy or reducing side effects. Such methods and compositions are particularly applicable to mustard-based alkylating agents such as uracil mustard and analogs, derivatives, or prodrugs thereof, including 6-methyluracil mustard and 6-ethyluracil mustard.

The present invention describes methods and compositions for improving the therapeutic efficacy of therapeutically active agents previously limited by suboptimal therapeutic performance by either improving efficacy as monotherapy or reducing side effects. Such methods and compositions are particularly applicable to therapeutically active agents selected from the group consisting of: (i) indirubin; (ii) an analog of indirubin; (iii) a derivative of indirubin or of an analog of indirubin; and (iv) a pharmaceutical composition comprising indirubin, an analog of indirubin, or a derivative of indirubin or of an analog of indirubin, especially meisoindigo. In particular, the therapeutically active agents selected from the group consisting of: (i) indirubin; (ii) an analog of indirubin; (iii) a derivative of indirubin or of an analog of indirubin; and (iv) a pharmaceutical composition comprising indirubin, an analog of indirubin, or a derivative of indirubin or of an analog of indirubin, especially meisoindigo, are effective Nek9 inhibitors. The active agent, such as meisoindigo, can act as a Nek9 inhibitor. The active agent can be used together with Nek9 inhibitors or agents that inhibit the expression of Nek9.

Methods and compositions suitable for the treatment of malignancies such as recurrent glioma and progressive secondary brain tumor are disclosed. These methods employ a hexitol derivative such as dianhydrogalactitol, a derivative or analog of dianhydrogalactitol, diacetyldianhydrogalactitol, or a derivative or analog of diacetyldianhydrogalactitol. The compositions can include such hexitol derivatives.
Solution-Phase and Solid-Phase Syntheses of Enzyme Inhibitor RK-682 and Antibiotic Agglomerins

The enzyme inhibitor RK-682 (5R)-(+)-1 was prepared in solution and on a solid support from (2R)-glycerates in five steps and ca. 40% overall yield. Key steps were a ring-closing tandem addition-Wittig alkenation reaction of the respective protected or immobilized glycerates with the ylide Ph-3-PCCO and the 3-acylation of the tetronic acids thus obtained with palmitic acid. A similar route extended by a mesylation-elimination sequence led to antibiotic agglomerins A-C 2 featuring 3-acyl-5-methylidenetetronic acid structures.
