报告摘要:
Naturalproteins/peptidespossessimportantbiologicalfunctionsandarewidelystudiedforbiomedicalandtissueengineeringapplications.However,theirdrawbackssuchasintolerancetoenzymaticdegradation,expensivenessanddifficultyforlarge-scalesynthesislimitthepracticalapplication.Wehypothesizethatsyntheticpolymerscanmimicthesequencedefinednaturalpeptidestoobtainimportantbiologicalfunctions.Weestablishwater-tolerant,fastandcontrollablepolymerizationmethodforconvenientandscalablesynthesisofaminoacidpolymers.Byintroducingunnaturalaminoacids,theresultingpolymersresistproteolysisandhavestablebiologicalfunctions.Ourrecentstudiesdemonstratethatourpolymericstrategyisvalidtomimicdifferenttypesofnaturalpeptides.Bymimickingextracellularmatrixpeptides,wediscoveraminoacidpolymersthatpromoteosteoblastadhesioncomparabletothegoldstandardRGDpeptide,andshowexcellentinvivobonerepairfunction.Bymimickinghostdefensepeptide(HDP),wefindpolymersthathavepotentactivityagainstdrug-resistantbacteriaanddrug-resistantfungi,aswellaslowhemolysisandlowcytotoxicity.Theoptimalantimicrobialpolymersarecomparableto,orevensuperiorto,theperformanceofcurrentantimicrobialdrugsbothinvitroandinvivo.Notably,theseHDP-mimickingpolymersdon’tcauseresistanceinbacteriaandfungiaftercontinuoususe.Thesestudiesindicatethatpeptide-mimickingpolymerscanhaveawiderangeofapplicationsasthenextgenerationbioactivematerials.
