Synthesis of Unnatural 2-Substituted Quinolones and 1,3-Diketones by a Member of Type III Polyketide Synthases from Huperzia serrata
摘要:
A curcuminoids, benzalacetone-, and quinolone-producing type III polyketide synthase (HsPKS3) from Huperzia serrata uniquely catalyzes the formation of unnatural 2-substituted quinolones and 1,3-diketones via head-to-head condensation of two completely different substrates. The broad range of substrate tolerance of HsPKS3 facilitates accessing structurally diverse 2-substituted quinolones and 1,3-diketones.

drug-like properties. In the present hit expansion study, 14 new 2-aryl-4-(4-aryl-2-oxobut-3-en-1-ylidene)benzothiazepanes were successfully synthesized through the implementation of various aromatic ring modifications and subsequently tested for cancercellcytotoxicity using eight different cancercell lines, revealing useful structure-activity relationship insights for this new class of compounds.
