新型吲哚-嘧啶联芳类化合物的设计、合成及抗肿瘤活性研究(英文) Title:Design,Synthesis,andAntitumorActivityofNovelIndole-PyrimidineFusedAromaticCompounds Abstract: Cancerremainsaleadingcauseofglobalmorbidityandmortality,necessitatingthecontinuousdevelopmentofnoveltherapeuticstrategies.Inthisstudy,wefocusonthedesign,synthesis,andevaluationoftheantitumoractivityofaseriesofnewlydevelopedindole-pyrimidinefusedaromaticcompounds.Thesecompoundsweredesignedtopossessahybridmolecularstructure,combiningtheadvantagesofboththeindoleandpyrimidinemoieties. Introduction: Indoleandpyrimidinederivativeshavebeenwidelyrecognizedfortheirsignificantcontributionstodrugdiscoveryanddevelopment,particularlyinthefieldofcancertherapy.Severalindoleandpyrimidine-baseddrugshaveshownremarkableantitumoractivity.However,thedesignandsynthesisofnewindole-pyrimidinefusedaromaticcompoundswithimprovedantitumoractivityremainanongoingchallenge.
