quantitative structure-activity relationship (3D-QSAR)/comparative molecular similarity indices analysis (CoMSIA) methods have been successfully applied to explain the cytotoxicactivity of a set of 51 natural and synthesized naphthoquinone derivatives tested in human promyelocytic leukemia HL-60 cell line. The computational models have facilitated the identification of structural elements of the ligands
Avicequinone C (5a), a furanonaphthoquinone isolated from the Thai mangrove Avicennia marina has been shown previously to have interesting steroid 5α-reductase type 1 inhibitory activity. In this study, a series of avicequinone Canalogues containing furanonaphthoquinone with different degrees of saturation and substituents at the furan ring were synthesized. The resulting synthetic avicequinone C and analogues
Naphthoquinones are considered privileged structures for anticancer drug molecules. The Heck reaction of 2‐hydroxy‐1,4‐naphthoquinone (lawsone) with 1‐bromo‐3‐methyl‐2‐butene offered easy access to lapachol. Several naturally occurring linear and angular heterocyclic quinoids (α‐lapachone, β‐lapachone, dunnione, and related analogues) were prepared from lapachol. Furthermore, we demonstrated that the

Lapachol (1), a naphthoquinone isolated mostly from the plants of the bignoniaceae family has a broad spectrum of biological activities and as a consequence it has been the object of different chemical transformations. Lomatiol (3), another naturally occurring naphthoquinone having structural similarities to lapachol, has been obtained from chemical and microbial transformations of lapachol in very

GC–MS (SIM mode) method for the identification of potential phase I metabolites in vivo. Plasma analysis of Wistar rats orally administered with lapachol revealed two metabolites, α-lapachone and dehydro-α-lapachone. Hence, the biomimetic model with a manganese salen complex has evidenced its use as a valuable tool to predict and elucidate the in vivo phase I metabolism of lapachol and possibly also
