萘醌是一类具有 1,4-萘醌核心结构的天然化合物,因其药理学特性而受到关注。这些化合物的抗癌活性归因于它们接受电子的能力,从而导致活性氧的产生,从而导致 DNA 损伤和细胞死亡。在最近的研究中,羟基-1,4-萘醌衍生物,包括柔红霉素,已显示出对多种人类癌症的良好抑制作用,例如急性髓性白血病、慢性粒性白血病和卡波西肉瘤。为了进一步探索它们作为抗癌剂的潜力,本文重点关注天然产物启发的基于萘醌的糖杂化物的设计和合成。这些糖杂化物是根据生物活性芳基糖苷和醌的结构设计的,旨在增强它们对癌症相关蛋白靶点的结合亲和力和特异性。通过计算对接模拟研究了合成的糖杂化物与靶蛋白之间的相互作用,并发现了更好的结合亲和力。

Provided herein are naphthoquinones compounds such as those with a hydrogen bond donating group of the formula (I): wherein: R1, R2, R3, R4, R5, and n are as defined herein. Also provided herein are pharmaceutical composition of the present compounds and methods of treatment using the compounds including their use in the treatment of cancer.
An efficient one-potsynthesis of 2H-pyranonaphthoquinone was achieved via a palladium-catalyzed C–H bondactivation/C–Cbond formation/intramolecular Tsuji–Trost reaction cascade. The unprecedented procedure exhibits excellent functional group tolerance, giving the target naphthoquinones in moderate to good isolated yields (40–88%) under mild reaction conditions. Scalable production of the product
Palladium(II)-Catalyzed Reaction of Lawsones and Propargyl Carbonates: Construction of 2,3-Furanonaphthoquinones and Evaluation as Potential Indoleamine 2,3-Dioxygenase Inhibitors
An efficient reaction utilizing propargyl carbonates through Claisen rearrangement to synthesize furanonaphthoquinones is described. The remarkable transformation exhibits excellent functional group tolerance, affording the target furanonaphthoquinones in moderate to good yields (41–85%) undermildreactionconditions. Scaled-up preparation of the model product can make this reaction a method of choice
A palladium-promoted oxidative annulation reaction for the synthesis of structurally diverse naphthoquinone-containing heterocycles has been developed, providing switchable access to 1,2-naphthofuroquinones and densely functionalized cyclobutene-fused 1,4-naphthofuroquinones by selective enol/enolate-directed processes. The synthetic application was extended by late-stage functionalization of an anti-HIV
Substituted naphthoquinones of the formula (I) and pharmaceutically acceptable salts thereof wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 represent alkyl, aryl, alkoxy, hydroxy, hydrogen or halogen or any two of the groups R.sub.1, R.sub.2, R.sub.3 and R.sub.4 taken together complete a carbocyclic ring, have useful anti-allergy activity in mammals.
