A new hypothesis regarding the effect of vitamin K3 on hepatoma cell growth is presented. In brief, exploration of cell growth activity has been identified with the action of p34(cdc2) kinase and its associated protein tyrosine phosphatase. After exploring a series of substituted derivatives of vitamin K and vitamin K3 oxide, we suggest a mechanism involving alkylation at the active-site cysteine for the inhibition of the protein tyrosine phosphatase which controls the activity of the p34(cdc2) kinase.

Paragraph 0021, (2020/05/30)
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.

Paragraph 0018, (2016/11/14)
The invention discloses a preparation method of 2-butyl sulfoxide-1,4-naphthoquinone. The method solves the problem that in the prior art, the requirements of study and application are far from being met when naphthoquinone compounds are extracted and separated only from plants. The preparation method specifically includes the two steps of firstly, synthesizing 2-butyl sulphur-1,4-naphthoquinone, wherein 1-butyl mercaptan and 1,4- naphthoquinone are made to react for 3-5 hours at the room temperature, sodium dichromate and concentrated sulfuric acid are added, the mixture continues to react for 5-10 minutes, and the product is post-processed to obtain 2-butyl sulphur-1,4-naphthoquinone; secondly, synthesizing 2-butyl sulfoxide-1,4-naphthoquinone, wherein 2-butyl sulphur-1,4-naphthoquinone and 3-chloroperoxybenzoic acid react for 1.5-2.5 hours at the temperature of 0 DEG C, and the product is post-processed to obtain 2-butyl sulfoxide-1,4-naphthoquinone. The preparation method is simple in synthesis route and low in reaction temperature, and the obtained product 2-butyl sulfoxide-1,4-naphthoquinone is obvious in anti-cancer effect and high in selectivity to cancer cells.
2-butyl sulfoxide-1,4-naphthoquinone compound
-
Paragraph 0020, (2017/01/02)
The invention discloses a 2-butyl sulfoxide-1,4-naphthoquinone compound which solves the problem that the research on 1,4-naphthoquinone without any substituent groups at the fifth bit and the eighth bit is little. The structural formula of the compound can be seen in the description. No substituent groups are arranged at the fifth bit or the eighth bit of the compound, the second bit is substituted by sulfydryl, sulfur at the second bit is oxidized into sulfoxide, and the naphthoquinone compound can have more excellent anti-cancer activity.

We report a new series of naphthoquinone derivatives as potent ACAT inhibitors, which were obtained through structural variations of previously disclosed lead 1. Several analogs represented by 3i-l, 4k-m, 6a-n, 7a, and 7i demonstrated potent human macrophage ACAT inhibitory activity by a cell-based reporter assay with human HepG2 cell lines. In particular, compounds 4l and 6j emerged as highly potent inhibitors, exhibiting significantly high inhibitory potencies with IC50 values of 0.44 μM and 0.6 μM, respectively. Moreover, compound 4l significantly reduced the accumulation of cellular cholesterol in HepG2 cell lines.
