Naphthoquinone Derivatives Targeting Melanoma

Current Topics in Medicinal Chemistry, 2023
Abstract: Cancer is responsible for high mortality rates worldwide, representing a serious health problem. In this sense, melanoma corresponds to the most aggressive type of skin cancer, being the cause of the highest death rates. Therapeutic strategies for the treatment of melanoma remain limited, with problems associated with toxicity, serious side ...

Dihydroxyacetone Naphthoquinone Sunscreen

JAMA: The Journal of the American Medical Association, 1972
To the Editor.— During the past decade, we have successfully used a sunscreen containing dihydroxyacetone/ naphthoquinone (lawsone) for patients with all types of cutaneous photosensitivity. 1 An advantage of this sunscreen is its capacity to induce a broad "ultraviolet shield" (290 to 405 nm) in the uppermost layer of the skin.

Organocatalytic atroposelective synthesis of naphthoquinone thioglycosides from aryl-naphthoquinones and thiosugars

Chemical Communications, 2023
A stereoselective organocatalytic strategy was developed to synthesize the axially chiral naphthoquinone thioglycosides from aryl-naphthoquinones and thiosugars. The reaction pathway involves atroposelective addition and stereoretentive oxidation.

Tubulin‐Perturbing Naphthoquinone Spiroketals

Chemical Biology & Drug Design, 2008
Several natural and synthetic naphthoquinone spiroketals are potent inhibitors of the thioredoxin–thioredoxin reductase redox system. Based on the antimitotic and weak antitubulin actions noted for SR‐7 ([8‐(furan‐3‐ylmethoxy)‐1‐oxo‐1,4‐dihydronaphthalene‐4‐spiro‐2′‐naphtho[1″,8″‐de][1′,3′][dioxin]), a library of related compounds was screened for ...

The Use of Naphthoquinones and Furano-naphthoquinones as Antiinvasive Agents

Current Medicinal Chemistry, 2019
Background: Cancer is a leading cause of mortality in the world and metastasis is to blame. A number of naphthoquinones (NQs) have shown ability to reduce cancer stemness and metastatic potential. Furano-naphthoquinones (FNQs), which is a class of NQ characterized by the incorporation of an additional furan ring, have demonstrated improved anti ...
