Inhibition of Zika Virus Replication by Synthetic Bis-Naphthoquinones
摘要:
Zika virus (ZIKV) is a mosquito-borne pathogen which is a current global public health concern. There are currently no approved vaccines or antivirals against ZIKV infection. Taking into account that naphthoquinones have shown promising antiviral activity, the aim of this study was to describe the screening of two bis-naphthoquinones series against ZIKV. Twenty seven compounds were evaluated against ZIKV using Vero cells. The findings showed that among the compounds analyzed four were promising. Compound 3.3' -((2-nitrophenyl)methylene)bis(2-hydroxynaphthalene-1,4-dione) containing the nitro group at the ortho position showed the best selectivity index, followed by compound 3,3'-(4-chlorophenylmethylene)bis(naphthalene-1,2,4-triyl triacetate) with the chlorophenylmethylene radical. These results demonstrate that these bis-naphthoquinones are largely effective in inhibiting the replication of ZIKV.

catalyst for the solvent-free preparation of 3,3'-(arylmethylene)-bis(2-hydroxynaphthoquinone) 3,3′-(arylmethylene)-bis(2-hydroxynaphthalene-1,4-dione)} derivatives in high yields and relatively short times. The one-pot pseudo-multi-component reaction of 2-hydroxynaphthoquinone (2-hydroxynaphthalene-1,4-dione) (2 eq.) and arylaldehydes (1 eq.) has been used for the preparation of these compounds. Graphic

compared to cisplatin, thus indicating the superiority of 1j as a possible anticanceragent. This compound was observed to induceapoptosis in the glioma cells by inducing the caspasedependent apoptotic pathways via ROS and downregulating the PI3K/AKT/mTOR pathway. Estimation of different oxidative stress markers also confirms the induction of oxidative stress in 1j exposed cancer cells. The toxicity of 1j
