Mutants not expressing UL12 can synthesize it almost wild-type viral DNA, suggesting that UL12 is not essential for replication of viral DNA in culture re U 15 February 2008, revised 18th April 2008, adopted 7th May 2008, published online at all On 16 Sent in June 2008 to: Prof. Dr. TY Ho, Graduate Institute of Chinese Medical Science, A 922500 Diacylglycerol acyltransferase 1 inhibitor China Medical University, 91 Hsueh Shih Road, Taichung, Taiwan 40 402, Taiwan.

Although not UL12 for viral DNA synthesis absolutely necessary, but UL12 mutant virus yields of 0.1 to 1% of wild-type yields. Analysis of the UL12 null mutants showed that the lower results of the virus yield reduction capsids leave the nucleus.
The analysis of DNA replication of cells Aloe-emodin 481-72-1 mutantinfected UL12 showed that UL12 from the L Solution of branched structures is involved intermediate-replicative HSV-1 before packaging. Therefore, these results indicate that, w While UL12 is not required for viral DNA synthesis or whether the packaging important UL12, which is of these procedures for the full effect. Furthermore, these results suggest that HSV-1 UL12, a new target for antiviral herpes be. The increase in the emergence of resistant strains Virusst The critical need for the development of new anti-herpes virus underlined by different mechanisms. Several m Possible objectives viral, such as helicase-primase complex and DNA polymerase, are known to participate in the HSV-1 infection and identified for the specific inhibitors of the fight against HSV with the activity of t, at least in cell cultures.
In this study we analyzed the potent inhibitor of HSV-1 UL12 that viral aligned. Our results show that emodin, anthraquinone present naturally inhibited in the root and bark of numerous plants of the genus Rheum and Polygonum, HSV-1 UL12 activity of t, leading to the accumulation of nucleocapsids in the nucleus and then End reduction in HSV-1 yields Vero cells. Methods Materials All chemicals, unless otherwise specified, were purchased from Sigma. Plant materials were purchased from Sun Ten Pharmaceutical Corporation. Plant samples were ground to fine powders with homogenizers and with methanol, as described above. Emodin and their analogs in dimethyl sulfoxide gel St. Diphenyltetrazolium bromide was 2.
5 3 solution in phosphate-buffered saline. Bovine pancreatic DNase I was purchased from New England Biolabs. Mouse monoclonal antibody Body against HSV-1 nucleocapsid protein and fluorescein-conjugated antibody Body goat anti-mouse were purchased from Jackson ImmunoResearch Laboratories and USBiological, respectively. Monkey kidney cells and viruses fibroblasts cells were purchased from the Bioresource Collection and Research Center, were cultured in Dulbecco, modified Eagle medium with 10% f Fetal K Calf serum and supplemented at 37 1C in a humidified CO 2nd Laboratory strain of type 1 virus was used, and the viral stock was prepared and titrated in Vero cells. Cloning, expression and purification of recombinant HSV-1 UL12 gene, to clone the HSV-1 UL12 was, the viral genomic DNA RKT from HSV-1 infected Vero cells, as described above verst And for 35 cycles with P and M UL12 UL12 primers extracted. The 1897 bp fragment of the UL12 gene was inserted into EcoRI and BamHI sites of histidine-tagged
