Dual combination of resveratrol and pterostilbene aqueous core nanocapsules for integrated prostate cancer targeting

Aim: Development and evaluation of aqueous core nanocapsules (ACNs) of BCS-II-class drug like resveratrol (RSV) and pterostilbene (PTE) for prostate cancer.Materials & methods: Identify synergistic effects of molar ratios of RSV and PTE against PC-3 cell. Selected ratio of drugs was added to ACNs by double-emulsification-method using Box-Behnken design. Further, assessed for physicochemical characterization, release kinetics, compatibility, in vitro cytotoxicity, in vivo pharmacokinetic and biodistribution studies.Results: Selected 1:1 ratio of RSV and PTE had greatest synergy potential have smaller particle-size (128.1 ± 3.21 nm), zeta-potential (-22.12 ± 0.2 mV), 0.53 PDI, improved encapsulation (87% for RSV, 72% for PTE), stable, no systemic toxicity, high biodistributed/accumulated in prostate cells.Conclusion: ACNs exhibited high t_1/2 (12.42 ± 1.92 hs) and 8.20 ± 8.21 hs Mean Residence Time and lower clearance, proving the high effectiveness for prostate cancer.
