Abstract:
Intensive cancer treatment with drug combination is widely exploited in the clinic but suffers from inconsistent pharmacokinetics among different therapeutic agents.To overcome it,the emerging nanomedicine offers an unparalleled opportunity for encapsulating multiple drugs in a nano-carrier.Herein,a two-step super-assembled strategy was performed to unify the pharmacokinetics of a pep-tide and a small molecular compound.In this proof-of-concept study,the bioinformatics analysis firstly revealed the potential synergies towards hepatoma therapy for the associative inhibition of exportin 1(XPO1)and ataxia telangiectasia mutated-Rad3-related(ATR),and then a super-assembled nano-pill(gold nano drug carrier loaded AZD6738 and 97-110 amino acids of apoptin(AP)(AA@G))was con-structed through camouflaging AZD6738(ATR small-molecule inhibitor)-binding human serum albumin onto the AP-Au supramolecular nanoparticle.As expected,both in vitro and in vivo experiment results verified that the AA@G possessed extraordinary biocompatibility and enhanced therapeutic effect through inducing cell cycle arrest,promoting DNA damage and inhibiting DNA repair of hepatoma cell.This work not only provides a co-delivery strategy for intensive liver cancer treatment with the clinical translational potential,but develops a common approach to unify the pharmacokinetics of peptide and small-molecular compounds,thereby extending the scope of drugs for developing the advanced com-bination therapy.
