Abstract

Present study deals with fabrication of macromolecular prodrugs (MPDs) of flurbiprofen (FLB) with hydroxyethylcellulose (HEC). FLB was activated using p-toluenesulfonyl chloride and reacted with pre-dissolved HEC to yield HEC-FLB conjugates 1–3. Resultant prodrugs showed moderate to high degree of substitution (DS: 0.40–1.74) and assembled into nanoparticles of 220–550 nm at water/DMSO interface. Pharmacokinetic studies of HEC-FLB conjugate revealed a tmax of 4.0 h indicating delayed release of FLB while t1/2 of 10.63 h indicated sustained release characteristics of the conjugate in rabbit model. Pharmacological studies revealed that HEC-FLB conjugates had immunomodulatory potential as results showed 34 and 36% inhibition of Interleukin-6 and tumor necrosis factor-α, respectively. A 79% inhibition of paw edema indicated anti-inflammatory properties of the conjugates. Cell viability studies indicated safety of the conjugates to L929 cell lines up to 24 h in the range of 2–10 mM. Moreover, thermal analysis indicated greater stability of MPDs than FLB.
