- Inhibition of Ca2+-activated and voltage-dependent K+ currents by 2-mercaptophenyl-1,4-naphthoquinone in pituitary GH3 cells: contribution to its antiproliferative effect.
-
Quinones have been shown to possess antineoplastic activity; however, their effects on ionic currents remain unclear. The effects of 2-mercaptophenyl-1,4-naphthoquinone (2-MPNQ), menadione (MD) and 1,4-naphthoquinone (1,4 NQ) on cell proliferation and ion

- Synthesis method of thioether compound containing 1,4-naphthoquinone structure
-
The invention belongs to the technical field of organic chemical synthesis, and discloses a synthesis method of a thioether compound containing a 1,4-naphthoquinone structure; the thioether compound containing the 1,4-naphthoquinone structure is prepared by carrying out a reaction on a tetralone compound with a sulfoxide compound under the catalytic action of iodine, the reaction temperature is 60-100 DEG C, and the reaction time is 6-24 h. Compared with a synthesis method in the prior art, the method has the advantages that the naphtholone compound which is cheap, easy to obtain, wide in source, stable and low in toxicity and the low-toxicity odorless sulfoxide compound can be used for generating the thioether compound containing the 1,4-naphthoquinone structure through one-step reaction,the requirement for green chemistry is met, the requirement of the method on reaction conditions is low, and the yield of the obtained product is relatively high.

- CONDENSATION INDOLE/NAPHTHOQUINONE. SYNTHESE D'UNE NOUVELLE SERIE D'INDOLYL-1,4-NAPHTHOQUINONES
-
Addition of an indole, which does not have a group at the 3-position, to 1,4-naphthoquinone leads to the expected 2-(3-indolyl)-1,4-naphthoquinone.When the 1,4-naphthoquinone is substituted at the 2-position by an alkyl or aryl group, the 2-substituted 3-(3-indolyl)-1,4-naphthoquinone is easily formed.However, when the 2-substituent of the quinone is functional (OH, OMe, Cl, Br, NC5H10, S-C6H5), in addition to the new series of expected indolylnaphthoquinones, several by-products resulting from elimination of the 2-substituted and/or further reaction of these compounds are formed.The outcome at the reaction appears to be very sensitive to the experimental conditions.
