  • Six novel 5-substituted-1-[2-(3-methoxy-2-hydroxyphenyl)-1-methoxyethyl]uracils 2a-f were prepared by condensation of 2,4-bis(trimethylsilyloxy)-5-substituted uracils with 2,7-dimethoxy-2,3-dihydrobenzofuran (9) in the presence of Lewis acid. The 2,3-dihydrobenzofuran derivative 9 was obtained by intramolecular acetalization of 2-acetoxy-3-methoxyphenyl acetaldehyde (8) which was synthesized by oxidative cleavage of 1-allyl-2-acetoxy-3-methoxybenzene (7) using osmium tetroxide followed by $NaIO_4$. Compounds 2a-f were evaluated for in vitro antiviral activity against HSV-1, HSV-2 and HRV. None of these compounds showed activity with $ID_{50}$ values up to $100\;{\mu}g/ml$ except for 5-chlorouracil derivative 2d which exhibited antiviral activity against HSV-1 with $ED_{50}$ $30\;{\mu}g/ml$. In the antitumor activity against L1210 and P388 leukemia cell lines, 2d showed activity with $ID_{50}$ values of $14\;{\mu}g/ml$ and $11.6\;{\mu}g/ml$, and 2c with $ID_{50}$ values of $22.9\;{\mu}g/ml$ and $8.8\;{\mu}g/ml$, respectively.

  • Benzopyrene (BP), 7,12-dimehyl benzanthracene (DMBA), nitrosomethyl urea (NUMU) 및 nicotine과 같은 발암성 화학물질들이 바이러스 감염된 vero 세포의 단층 세포 배양에서 I형 단순성포진 바이러스 (HSV-1)의 복제, 세포융해, DNA합성 및 단백질 합성에 미치는 효과를 관찰하였다. 1. BP와 DMBA는 HSV-1의 복제와 세포융해작용을 유의성있게 억제하였으나 nicotine과 NMU는 별로 억제하지 않았다. 2. 모든 발암성 화학물질은 바이러스의 DNA합성을 억제하지 못하였지만 새로 합성되는 후손바이러스 DNA로 부터 표현되는 gamma 단백질의 표현은 BP와 DMBA에 의해서 현저하게 억제되었다. 그러나 모든 발암성 화학물질은 바이러스의 alpha 및 beta 단백질의 합성은 억제하지 못하였다. 이상의 결과로 보아 발암성화학물질이 존재하고 있는 배지내에서 새로 합성되는 바이러스의 DNA로 부터 표현되는 gamma 단백질의 결함이 있음을 알 수가 있었으며 이같은 개념은 발암화학물질의 존재하에서 바이러스의 DNA와 단백질이 거의 정상적으로 합성됨에도 불구하고 바이러스의 복제가 일어나지 않는다는 사실이 뒷받침해주고 있다.

  • 단순 헤르페즈 제1형 티미딘 키나제(Herpes simplex virus type 1 thymidine kinase. HSV1-tk) 유전자는 보고 유전자(reporter gene)로서 필요한 조건뿐만 아니라 별도의 치료 유전자를 따로 이입할 필요가 없다는 장점을 가지고 있어 유전자 영상과 치료에서 가장 널리 사용되는 유전자 중 하나이다. 본 연구는 HSV1-tk 보고 유전자의 기질로서 많이 사용하고 있는 9-(4-[$^{18}F$] Fluoro-3-hydroxymethylbutyl) guanine ([$^{18}F$] FHBG) 합성의 자동화와 더불어 최적의 합성 조건을 구현하기 위하여 실행하게 되었다. [$^{18}F$] FHBG 합성의 자동화를 위해 Explora-RN (CTI, USA) module을 사용하였다. 최적의 합성수율 조건을 찾기 위하여 반응시간의 변화(3 min, 5 min, 10 min)와 반응온도의 변화($110^{\circ}C$, $120^{\circ}C$, $130^{\circ}C$)를 주었다. 또한 precursor 용량의 변화(5 mg, 7 mg, 10 mg)에도 합성수율이 어떻게 영향을 미치는지 알아보았다. [$^{18}F$] fluorination 단계에서 가장 높은 합성수율을 보인 반응온도는 $130^{\circ}C$였고, 반응시간은 5분이었다. 반면 precursor의 용량 변화 실험에서는 10 mg을 넣었을 때의 합성 수율($32{\pm}1.2%$)에 비하여 5 mg과 7 mg의 양에서는 안정된 값을 얻지 못하였다. [$^{18}F$] FHBG 합성의 Explora-RN 모듈에서의 자동화를 완성하였고 최적의 합성수율을 재현할 수 있는 반응시간과 반응온도, precursor의 농도를 찾았다. 하지만 감량 precursor 방법은 낮은 농도에서 비교적 큰 편차를 보여 안정된 값을 얻지는 못하였다. 이에 따라 임상에 직접 적용하기 위해서 더 많은 연구가 시행되어져야 할 것이다.

  • Novel 2'(${\beta}$)-fluoro-3'(${\alpha}$)-hydroxy-threose nucleosides (iso-FMAU) as antiviral agents were designed and racemically synthesized from Solketal. Condensation successfully proceeded from a glycosyl donor 9 under $Vorbr{\ddot{u}}ggen$ conditions yielded the nucleoside analogues. Ammonolysis and hydrolysis of isopropylidene protection group gave the desired nucleoside analogues 12, 15, 18, and 19. The antiviral activities of the synthesized compounds were evaluated against the HIV-1, HSV-1, HSV-2 and HCMV. Compound 12 displayed some anti-HCMV activity ($EC_{50}=24.7{\mu}g/ml$) without exhibiting any cytotoxicity up to $100{\mu}M$.

  • 항암성 또는 항 virus성 약물개발 목적으로 천연의 pyrimidine nucleoside의 구조유사체로 pyrimidine acyclonucleoside들을 합성하였다. Pyrimidine acyclonucleoside를 염기 uracil, thymine 및 5-fluorouracil을 원료로 하여 합성하고 구조를 NMR, IR data를 써서 확인하였다. 이들 합성 화합물들은 L$_{1210}$ 암세포를 이용하여 in vitro 항암성 작용을 검색하였다. 합성된 화합물들 중 5-fluorouraoil-acyclonucleoside들은 약간이나마 모 5FU보다 높은 항암성 작용을 보였다. 유도체들은 5-FU의 N$^1$에 glycosidic 결합이 아닌 alkyl 결합을 하고있어, 모 5FU를 그리 쉽게 유리시키리라 보아지지 않으므로 이들의 작용성은 acyclonucleoside형태일 것 같아 이들의 작용기전 연구가 필요하다고 보아진다. 한편 얻은 유도체들은 HSV-1 및 HSV-2를 이용하여 항 virus성 작용을 검색한 결과 2500$\mu\textrm{g}$/ml 농도에서 유의성 있는 억제 작용성을 보이지 않았다.

  • Novel fluoro-substituted apio dideoxyuncleoside(($\pm$)-3a and ($\pm$)-3b) were efficiently synthesized stalling from 1,3-dihydroxyacetone via Horner-Emmons olefination as a key step. Cyclization of fluoro ester ($\pm$)-6 under acidic conditions to the fluorolactone was smoothly proceeded in favor of trans-fluorolactone due to the favorable transition state with equatorial hydroxymethyl substituent. Unfortunately the final nucleosides($\pm$) -3a and ($\pm$)-3b were found to be inactive against several viruses such as HIV-1, HSV- I , HSV-2 and HCMV.

  • The stereoselective synthesis 4′,6′-dually branched carbocyclic nucleosides was accomplished in this study. The introduction of a methyl group in the 6′$({\alpha})$-position was accomplished by Felkin-Anh controlled alkylation. The construction of the required 4′$({\alpha})$-quaternary carbon was carried out using a [3,3]-sigmatropic rearrangement. Bis-vinyl 6 was successfully cyclized using a Grubbs' catalyst II. The natural bases (adenine, cytosine) were efficiently coupled using a Pd(0) catalyst. When the synthesized compounds were examined for their activity against several viruses such as the HIV-1, HSV-1, HSV-2 and HCMV, the cytosine analogue 13 exhibited good antiviral activity against the HCMV.

  • A 59-year old man was admitted for drowsiness and stiff neck. CSF examination showed lymphocytic pleocytosis and PCR for herpes simplex virus (HSV)-1 was positive in CSF. Brain MRI revealed enhanced lesions in left temporal lobe. His symptom improved with acyclovir. Follow-up studies showed red blood cells in CSF and a hematoma in the left temporal lobe. There was no additional symptom related to the hematoma. He was discharged after conservative care. Although rare, hematoma can develop in HSV-1 meningoencephalitis.

  • This paper describes the racemic and stereoselective synthetic route for a novel 4'$\alpha$-phenyl and 6'$\alpha$-methyl doubly branched carbocyclic nucleosides from an acyclic 2-hydroxy acetophenone. The installation of phenyl group at the 4'-position of carbocyclic nucleoside was successfully accomplished via a sequential [3,3]-sigmatropic rearrangement. The stereoselective introduction of a methyl group in the 6'$\alpha$-position was accomplished by Felkin-Anh controlled alkylation. Bis-vinyl 11 compound was successfully cyclized using a Grubbs’ catalyst II to desired carbocycles. The natural bases (adenine and cytosine) were efficiently coupled using a Pd(0) catalyst. Although all the synthesized compounds were examined for their activity against several viruses such as HIV-1, HSV-1, HSV-2 and HCMV, only cytosine analogues 17 exhibited weak antiviral activity against HCMV.
