Abstract

A series of S-(2,2-diethoxycarbonyl-1-phenylethyl)-L-glutathione derivatives (11a-e) were synthesized from the reaction of ${\beta},\;{\beta}$-diethoxycarbonylstyrene with L-glutathione in 9 : 1 aqueous methanol. Thus, S-(2,2-diethoxycarbonyl-1-phenylethyl)-L-glutathione (11a), S-2,2-diethoxycarbonyl-1-(3',4'-methylenedioxy)phenylethyl-L-glutathione (11b), S-2,2-diethoxycarbonyl-1-(3',4',5'-trimethoxy)phenylethyl-L-glutathione (11c), S-2,2-diethoxycarbonyl-1-(4'-hydroxy)phenylethyl-L-glutathione (11d), S-2,2-diethoxycarbonyl-1-(4'-methoxy)phenylethyl-L-glutathione (11e) were obtained in good yields. The structure of the adducts was characterized by analytical and spectral data. The effects of pH and solvents upon the yields were also briefly examined. In the range of pH from 4.0 to 8.0, the aqueous methanol were found to be the best solvent for the addition reaction and the antibacterial activities of the adducts to Gram(+) bacteria were found to be weak.

물-메탄올(9:1) 용매 속에서 ${\beta},\;{\beta}$-diethoxycarbonylstyrene과 L-glutathione을 반응시켜 좋은 수득율로 다음과 같은 화합물을 합성하였다. 즉 S-(2,2-diethoxycarbonyl-1-phenylethyl)-L-glutathione, S-2,2-diethoxycarbonyl-1-(3',4'-methylenedioxy)phenylethyl-L-glutathione, S-2,2-diethoxycarbonyl-1-(3',4',5'-trimethoxy)phenylethyl-L-glutathione, S-2,2-diethoxycarbonyl-1-(4'-hydroxy)phenylethyl-L-glutathione, S-2,2-diethoxycarbonyl-1-(4'-methoxy)phenylethyl-L-glutathione. 위 화합물들의 구조는 원소분석과 분광학적 방법으로 확인하였고 수득율에 미치는 pH와 용매의 영향을 실험한 결과 pH는 4.0에서 8.0사이가 용매는 물-메탄올이 가장 적합하다는 것을 알았다. 한편 이 화합물의 Gram(+) 박테리아에 대한 항균성을 실험한 결과 약함을 알았다.
