  • Eczema herpeticum is a widespread Herpes simplex virus(HSV) infection, which usually develops in patients with atopic dermatitis, because prutitis in patients with atopic dermatits leads them to scratch their bodies, it cause the dissemination of Herpes simplex virus. This study carried out to observe the progress of Eczema herpeticum and find effective remedy. The pastient was taken Herb-medicine with acupunture, cupping theraphy, aroma theraphy, and etc. After the treatment the grade of VAS was decressed and clinical symptoms were gradually disappeared. Those results suggest that herbal treatment was effective to Eczema herpeticum.

  • 면역 결핍 바이러스와 허피즈 바이러스 -1,2에 대한 한약의 항바이러스 작용을 관찰하기 위하여, 세포 바이러스 검색에 초기 독성과 감염 바이러스의 생존 세포 수를 비교적 단기간내 볼 수 있는 96-well plate를 이용한 MTT assay로 측정하였다. 본 실험은 예비 실험 단계에서 사용된 총 85가지의 한약중 단미제 6가지와 복합처방 44가지를 선정하였으며 복합처방은 유사한 치법으로 분류하였고 한약의 시료 추출은 순수하게 물로 전탕하여 여과하였다. 실험 결과 파두와 맥아가 면액 결핍 바이러스에 대해 감염초기 유의성이 있었으며 호장근, 갈근우방자탕과 형방패독산이 허피즈 바이러스-1,2에 대해 감염초기 유의성이 있었으나 실험의 시간 경과에 따른 지속적인 약효 안정성을 보이지는 못하였다. 이 실험을 통하여 한약을 이용한 우수한 바이러스 치료를 개발하기 위해서는 단미제나 복합 처방에서 항바이러스 작용이 큰 유효성분의 대량 분리와 세포 실험에 있어서 오차를 줄 일 수 있는 세포면역학적 실험의 도입 등이 필요할 것으로 사료된다.

  • Background: Herpes simplex virus type 1 (HSV-1), known to latently infect the host's trigeminal ganglion, can lead to severe herpes encephalitis or asymptomatic infection, potentially contributing to neurodegenerative diseases like Alzheimer's. The virus generates reactive oxygen species (ROS) that significantly impact viral replication and induce chronic inflammation through NF-κB activation. Nuclear factor E2-related factor 2 (Nrf2), an oxidative stress regulator, can prevent and treat HSV-1 infection by activating the passive defense response in the early stages of infection. Methods and results: Our study investigated the antiviral effects of ginsenoside Rg5, an Nrf2 activator, on HSV-1 replication and several host cell signaling pathways. We found that HSV-1 infection inhibited Nrf2 activity in host cells, induced ROS/NF-κB signaling, and triggered inflammatory cytokines. However, treatment with ginsenoside Rg5 inhibited ROS/NF-κB signaling and reduced inflammatory cytokines through NRF2 induction. Interestingly, the Nrf2 inhibitor ML385 suppressed the expression of NAD(P)H quinone oxidoreductase 1(NQO1) and enhanced the expression of KEAP1 in HSV-1 infected cells. This led to the reversal of VP16 expression inhibition, a protein factor associated with HSV-1 infection, thereby promoting HSV-1 replication. Conclusion: These findings suggest for the first time that ginsenoside Rg5 may serve as an antiviral against HSV-1 infection and could be a novel therapeutic agent for HSV-1-induced neuroinflammation.

  • Two triterpenes 1 and 2 with antiviral activity against Herpes simplex virus type 1 in vitro were isolated from Prunella vulgaris. Each compound caused a significant reduction in viral cytopathic effect when vero cells were exposed to them for 72 hours after viral challenge. They were identified as betulinic acid (1) and $2\alpha, 3\alpha$-dihydroxyurs-12-en-28-oic acid(2) on the basis of their spectroscopic properties. The antiviral activity of them was estimated as $EC_{50}=30\;\mu$g/ml(1) and $8\;\mu$g/ml(2), respectively by plaque reduction assay.

  • In order to find less toxic antiherpetic agents, antiviral activities of quercitrin against two strains of pathogenic viruses such as herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) were determined in Vero cells using plaque reduction assay in vitro. Quercitrin showed a concentration-dependent decrease in plaque formation of HSV-1 and HSV-2. It also exhibited more potent antiherpetic activity on HSV-1 with 50% effective concentration (EC$_{50}$) of 20.4 $\mu$g/ml than on HSV-2 with EC$_{50}$ of 30.4 $\mu$g/ml. The combined antiherpetic effects of quercitrin with nucleoside antiherpetic agents, acyclovir and vidarabine, were examined on the multiplication of these two strains of herpesviruses in Vero cells by the combination assay. The results of combination assay were evaluated by the combination index (CI) that was calculated by the multiple drug effect analysis. The combinations of quercitrin with acyclovir and vidarabine on HSV-1 showed more potent synergism with CI values of 0.27-0.81 for 50%, 70%, 90% effective levels than those on HSV-2 with CI values of 1.03~2.20..20.

  • We have investigated the biochemical properties of the herpes simplex virus type 1 (HSV-1) DNA polymerase without the UL42 protein (Pol), purified from insect cells infected with a recombinant baculovirus containing the UL30 gene. BSA and DTT have inhibitory effects on dAMP incorporation. Pol showed a greater turnover rate of steady-state single nucleotide incorporation at 12 mM $MgCl_2$ than at 2 mM $MgCl_2$. However, it showed a greater processivity of DNA synthesis at lower $MgCl_2$ concentration (1 mM, 2 mM) than at a higher $MgCl_2$ concentration (12.5 mM). These results are consistent with a slow DNA dissociation at lower $MgCl_2$ concentrations. Pol does not incorporate a correct nucleotide into the primer with an incorrect nucleotide at the end; instead, it preferentially excises the incorrect nucleotide at the 3' end of the primer. Pol has DNA polymerase activity at pHs 6.5 and 7.5 but little at pHs 5.5, 8.5, and 9.5. It has exonuclease activity at pHs 6.5, 7.5, and 8.5 but little at pHs 4.5, 5.5, and 9.5. The finding that Pol has exonuclease activity but not DNA polymerase at pH 8.5 suggests that DNA binds to Pol, but deoxynucleotide binding or incorporation does not occur at pH 8.5.

  • 19 Aromatic ring and L-amino acid ester contained rupestonic acid amide derivatives 2a~2l, 3a~3g were synthesized and preliminarily evaluated in vitro against influenza virus $A_3$,B and herpes simplex virus type 1 (HSV-1), 2(HSV-2) by the national center for drug screening of China. The rusults showed that 2i possessed the highest inhibition against both influenza virus $A_3\;(TC_{50}\;=\;120.6\;{\mu}mol/L,\;IC_{50}=\;19.2\;{\mu}$mol/L, SI = 6.3) and B (T$C_{50}\;=\;120.6\;{\mu}mol/L,\;IC_{50}=\;29.9\;{\mu}$mol/L, SI = 4.0); 2g was more active against influenza $A_3$ virus at very low cytotoxicity ($TC_{50}\;>\;2092.1\;{\mu}mol/L,\;IC_{50}=\;143.7\;{\mu}mol/L,$ SI > 14.6) than the parent compound; Compounds 2b, 2c, 2f showed higher activities both against HSV-1 and HSV-2 than that of the parent compound, and 2f was the most potent inhibitor of HSV-1 ($TC_{50}\;=\;200.0\;{\mu}mol/L,\;IC_{50}\;=\;11.3\;{\mu}mol$/L, SI = 17.7 ) and HSV-2 ($TC_{50}\;=\;200.0\;{\mu}mol/L,\;IC_{50}\;=\;20.7\;{\mu}mol$/L , SI = 9.7).

  • In order to find less toxic antiherpetic agents, the effect of natural quercetin on the plaque formation of herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) was studied in vitro in cell culture monolayers employing the technique of viral plaque reduction assay. Quercetin caused a concentration-dependent reduction in the plaque formation of herpesviruses. It also exhibited more potent antiherpetic activity on HSV-1 with effective concentration $(EC_{50})$ of $18.7\;{\mu}g/ml$ than on HSV-2 with $EC_{50}$ of $24.5\;{\mu}g/ml$. The combined antiherpetic effects of quercetin with nucleoside antiherpetic agents, acyclovir and vidarabine, were examined on the multiplication of these two strains of herpesviruses in Vero cells by the combination assay. The results of combination assay were evaluated by the combination index (CI) that was calculated by the multiple drug effect analysis. The combinations of quercetin with acyclovir on HSV-1 and HSV-2 showed more potent synergism with CI values of $0.19{\sim}0.89$ for 50%, 70%, 90% effective levels than those with vidarabine with CI values of $0.43{\sim}1.46$.
