Abstract: Copolymers of 4-[4-[(6-hydroxyhexyl)oxy]phenylazo] benzoic acid and 16-hydroxyhexadecanoic acid were prepared by polycondensation and evaluated as materials for colonic targeting. The in vitro degradation of the azo-polymers was performed in sonicated rat coecal content (cell-free extract) containing nicotinamide adenine dinucleotide phosphate, glucose-6-phosphate, glucose-6-phosphate dehydrogenase, and benzyl viologen as the redox mediator. The degradation of the azo-polymers was examined using UV absorption spectrometry and solution viscosimetry. The results of this study clearly demonstrate that the polymers can be degraded by rat bacterial azo-reductase to polymers with lower molecular weight, and may offer opportunities to develop colon-specific drug delivery systems.
