Biodegradable polymethacrylic acid grafted psyllium for controlled drug delivery systems

Ranvijay KUMAR, Kaushlendra SHARMA

Frontiers of Chemical Science and Engineering 2013, Volume 7, Issue 1,   Pages 116-122 doi: 10.1007/s11705-013-1310-0

Abstract: Polymethacrylic acid (PMA) was synthesized on the backbone of psyllium (Psy) by a microwave assisted method to prepare polymeric grafted materials designated as (Psy- -PMA). Various grades of Psy- -PMA were prepared by changing the degree of grafting from 35%–58% and the materials were then made into tablets. Swelling and biodegradability studies of the tablets were carried out. Acetyl salicylic acid was incorporated in the various Psy- -PMA samples and tablets were prepared to study the in vitro drug release in acidic (pH= 4), neutral (pH= 7), and basic (pH= 9) media. In the acidic medium, the swelling was more than 1300%. In addition, the biodegradable Psy- -PMA had the highest drug release in the acidic medium. This may be attributed to Fickian diffusion since the drug and the medium in which it was released have the same acidic nature.

Abstract: Benefiting from the advantage of taking place in biological environments without interfering with an innate biochemical process, the bioorthogonal reaction that commonly contains the “bond formation” and “bond cleavage” system has been widely used in targeted therapy for a variety of tumors. Herein, several prominent cases based on the bioorthogonal reaction that tailoring the metabolic glycoengineering tactics to modified cells for cancer immunotherapy, and the innovative tactics for reducing the metal ions’ toxic and side effects with microneedle patches will be highlighted. Based on these applications, the complexities, potential pitfalls, and opportunities of bioorthogonal chemistry in future cancer therapy will be evaluated.
