3-phenyl-5,5-dimethyloxazolidine-2,4-dione에 대한 형태 분석을 통하여 구조-활성 관계를 검토하였다. Antifungal Activity에 대한 구조적인 특징으로 활성기인 amide group(-NCO)와 벤젠 moiety가 존재하며, 강한 활성을 나타내는 유사체의 N원자와 para 치환기 간의 공간거리 N-X$_4$는 5.32∼5.37${AA}$, 3,5-치환기 간의 거리 X$_3$-X$_5$는 5.59 ∼ 5.77 ${AA}$을 나타내었다.
The relationship between chemical structure and antifungal activity of benzene ring substituents of 3-phenyl-5,5-dimethyloxazolidine-2,4-diones is studied by testing of model compounds and use of conformational data. The analysis revealed a number of structural features as essential for the antifungal effect: (1) the presence of an intact -NCO group and benzene moiety; (2) the distance between para substituents and the N atom within the 5.32∼5.37${AA}$ range; (3) the distance between substituents X3 and X4, in the interval 5.59 ∼ 5.77 ${AA}$ for the active analogues.
