Embodiment 1

[0046] The application of targeting thymidylate synthase (TS) in screening anti-herpes virus drugs comprises the following steps:

[0047] Pemetrexed disodium is known as a thymidylate synthase inhibitor, and this inhibitor is used to verify whether it has anti-herpes virus effects:

[0048] 1. Experimental materials

[0049] 1.1 Cells and viruses

[0050] iSLK.219 cells were donated by Professor Dr. Don Ganem. The cells are SLK cells containing recombinant virus rKSHV.219 and doxycycline (Doxycycline) regulated RTA expression system. In this cell, the RTA expression sequence was constructed into the pRetro-X Tet-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).

[0051] Pemetrexed disodium was purchased from Biochempartner.

Embodiment 2

[0087] The application of targeting thymidylate synthase (TS) in screening anti-herpes virus drugs comprises the following steps:

[0088] Pemetrexed disodium is known as a thymidylate synthase inhibitor, and this inhibitor is used to verify whether it has anti-herpes virus effects:

[0089] 1. Experimental materials

[0090] 1.1 Cells and viruses

[0091] 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 / mL TPA can make the virus enter the lytic phase and replicate.

[0092] 1.2 Reagents

[0093] 1640 medium and FBS were purchased from GIBCO; Alamarblue activity detection kit was purchased from Promega; SYBR mixture (iTaq TM Universal Green Supermix) was purchased from Bio-Rad Company.

[0094] 1.3 Experimental Instruments

[0095] The multi-label microplate reader was purchased from PerkinElmer; the fluorescent quantitat...

Embodiment 3

[0118] The application of targeting thymidylate synthase (TS) in screening anti-herpes virus drugs comprises the following steps:

[0119] Pemetrexed disodium is known as a thymidylate synthase inhibitor, and this inhibitor is used to verify whether it has anti-herpes virus effects:

[0120] 1. Experimental materials

[0121] 1.1 Cells and viruses

[0122] Vero cells were preserved in our laboratory and purchased from the American Type Culture Collection (ATCC). HSV-1 is an F strain, which is preserved by the Wuhan Institute of Virology, Chinese Academy of Sciences. HSV-2 is a G strain, which is preserved by the Wuhan Institute of Virology, Chinese Academy of Sciences.

[0123] 1.2 Reagents

[0124] DMEM medium and FBS were purchased from GIBCO; Alamarblue activity detection kit was purchased from Promega; crystal violet staining solution.

Abstract

The invention discloses application of thymidylate synthase as the target in screening anti-herpes virus drugs. thymidylate synthase can be used for screening drugs resisting Herpes simplex virus-1 (HSV-1), Herpes simplex virus-2 (HSV-2), Varicella zoster virus (VZV), EB virus (Epstein-Barr virus, EBV), Cytomegalovirus (CMV), human herpes virus type VI (HHV-6), human herpes virus type VII (HHV-7) and Kaposi's sarcoma-associated herpesvirus (KSHV) and other herpes viruses. The cell target thymidylate synthase involved in the invention can be used as a new anti-herpes virus target for drug development, and can be applied to treatment or prevention of herpes virus infection.

Description

technical field [0001] The invention relates to the field of biomedicine, in particular to the application of targeting thymidylate synthase in screening anti-herpes virus drugs. 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, mainly including: Herpes simplex virus-1 (HSV-1), Herpes simplex virus-2 (HSV-2), Varicella zoster virus (VZV), Epstein-Barr virus (EBV), cytomegalovirus (CMV), human herpes virus type VI (HHV-6), human herpes virus type VII (HHV-7) and Kaposi's sarcoma-associated herpesvirus (KSHV). According to the differences in genome sequence, structure and physical and chemical properties, Herpesviridae can be divided into three subfamilies: α-Herpesvirinae, β-Herpesvirinae and γ-Herpesvirinae. The life cycle of herpes virus is divided ...
