Abstract
Herein, we introduce a novel amphiphilic bioconjugate (INU-F68-SA), synthesized by functionalization of pluronic F68 with a polysaccharide inulin (INU) and a lipid stearic acid (SA). The synthesis of INU-F68-SA was confirmed by FTIR and 1H-NMR analysis. INU-F68-SA can self-assemble into nanomicelles and therefore, its application in delivering of hydrophobic resveratrol (RSV) was investigated. The RSV-loaded INU-F68-SA nanomicelles (RSNM) had about 172 nm size, spherical shape, 0.237 polydispersity index, and −18 mV zeta potential. More importantly, the RSNM showed high drug entrapment efficiency, controlled drug release and protection of drug during storage. The RSNM significantly enhanced the cytotoxicity of RSV against colorectal cancer cells by inducing apoptosis and changing mitochondrial membrane potential. Further, in-vivo pharmacokinetic experiment indicated an improvement in pharmacokinetics of RSV after administering as RSNM. Thus, the use of self-assembled nanomicelles of amphiphilic INU-F68-SA bioconjugate could be a better alternative to overcome the poor in-vitro and in-vivo performance of RSV.
