Embodiment 1

[0037] Detection of pemetrexed disodium inhibiting KSHV lytic phase replication

[0038] 1. Experimental materials

[0039] 1.1 Cells and viruses

[0040] The iSLK.219 cell was donated by Professor Dr. DonGanem. The cell is a SLK cell containing the recombinant virus rKSHV.219 and the RTA expression system regulated by Doxycycline. In this cell, the RTA expression sequence was constructed into the pRetro-XTet-ON inducible expression system (Clontech, Mountainview, CA), and the expression of this system was regulated by doxycycline. In the presence of doxycycline, RTA Expression can occur; 293T cells were preserved in our laboratory and purchased from American Type Culture Collection (ATCC).

[0041] Pemetrexed disodium was purchased from Biochempartner.

[0042] 1.2 Reagents

[0043] DMEM medium, 1640 medium and FBS were purchased from GIBCO; Alamarblue activity detection kit was purchased from Promega; SYBR mixture (iTaq TM Universal GreenSupermix) was purchased from B...

Embodiment 2

[0104] Detection of pemetrexed disodium inhibiting DNA replication in EBV lytic phase

[0105] 1. Experimental materials

[0106] 1.1 Cells and viruses

[0107] The B95-8 cell was donated by Professor Sun Xiaoping of the School of Basic Medicine of Wuhan University. The cell contains the complete sequence of the EBV virus genome. Combined induction with 20ng / mLTPA can make the virus enter the lytic phase and replicate.

[0108] 1.2 Reagents

[0109] 1640 medium and FBS were purchased from GIBCO; Alamarblue activity detection kit was purchased from Promega; SYBR mixture (iTaq TM Universal GreenSupermix) was purchased from Bio-Rad Company.

Abstract

The invention discloses application of pemetrexed disodium or pharmaceutically-acceptable salt thereof in preparing medicine for treating or preventing herpes virus infection. According to the application, pemetrexed disodium of a completely non-cytotoxic concentration is selected and used for conducting a herpes virus resisting experiment, the result shows that the compound has significant herpes virus resisting activity in dose dependency, and pemetrexed disodium performs the herpes virus resisting effect by inhibiting virus reproduction. Detection of herpes viruses of different subtypes shows that pemetrexed disodium has broad-spectrum herpes virus resisting activity, is high in selection index, can be developed into medicine for treating or preventing herpes virus infection and has broad application prospects.

Description

technical field [0001] The invention relates to the field of biomedicine, in particular to the application of pemetrexed disodium or a pharmaceutically acceptable salt thereof in the preparation of medicines for treating or preventing herpes virus infection. Background technique [0002] Herpesviridae is a family of viruses with envelopes and double-stranded DNA genomes. Members of this family can widely infect animals and humans and induce corresponding diseases. There are currently eight herpes viruses that can infect humans, including: Herpes simplex virus-1 (HSV-1), Herpes simplex virus-2 (HSV-2), Varicella-Zoster Herpes virus (Varicellazostervirus, VZV), Epstein-Barrvirus (EBV), cytomegalovirus (Cytomegalovirus, CMV), human herpesvirus type VI (HHV-6), human herpesvirus type VII (HHV-7) and card Bordeaux herpes virus (Kaposi's sarcoma-associated herpesvirus, KSHV). According to the differences in genome sequence, structure and physical and chemical properties, Herpes...
