DESCRIPTION (provided by applicant): The separation of enantiomers (i.e. chiral separations) is of great importance in the development of safe chiral pharmaceuticals and the study of chiral biological toxins and carcinogens. For pharmaceutical compounds that are chiral, usually one enantiomer (either the right or left-handed version) is the drug, while the other half causes side effects, different effects, similar effects or in limited cases, no effects. In the cas of biological toxins, understanding the chirality involved in their mechanism of action is necessary. This Small Business Innovation Research (SBIR) project will support the development of novel chiral selectors and chiral stationary phases based on the new cyclic oligosaccharide cyclofructan. Cyclofructans, or cycloinulooligosaccharides, are ¿-(2-1)-linked cyclic fructofuranose oligomers. In their native forms, they show little enantioselectivity when used as chiral stationary phases. However, Phase I results indicate that certain derivatives of cyclofructan make outstanding chiral selectors. This unique enantioselective chromatographic media is likely to be the greatest advancement in the resolution of enantiomers in the past 15 years. These chiral selectors will play a major role as separation media in pharmaceutical, medicinal, and synthetic organic chemistry. The aim of the Phase II proposal of this SBIR is to further develop these broadly effective chiral stationary phases and to bring them to the commercialization level. Specifically, we will develop the production means for these chiral stationary phases (i.e. synthesis and packing methods), test their reproducibility, build prototype columns for evaluation by experts in our target market, refine scale-up procedures to prepare for manufacturing, and begin marketing and forming strategic alliances with partners, distributors, and future investors. As a result of this proposed work, this technology will bring to market a new tool that will allow for the production of better and less expensive pharmaceutical products that have fewer side effects and can be given in lower doses. Also, we have better means to study their distribution and action in biological experiments and understand the biological actions of chiral toxins.
