분자구조를 기술하는 molecular connectivity index, Wiener index 및 ad hoc descriptor와 알코올, 에스테르, 케톤 화합물들이 생체내에서 나타내는 enzyme inhibitory potency, lipoxygenase inhibition, tadpole narcosis potency, 증기독성(vapor toxicity), 증발열(heat of vaporization)과 같은 성질들 사이의 상관관계를 조사하였다. 생물학적 활성의 종류에 따라 molecular descriptor 사이의 우열은 있으나, 대체로 좋은 상관관계식을 얻었다.

Various biological activities (enzyme inhibitory potency, lipoxygenase inhibition, tadpole narcosis, vapor toxicity and heat of vaporization) of molecules are correlated with molecular descriptors. The molecular descriptors used in this works are molecular connectivity index, Wiener distance index and ad hoc descriptor, which can encode information about branching, size, cyclization, unsaturation, hetero atom content and polarizability. It is found that calculated values from multiple regression equations are in a good agreement with experimental data on five biological activities of alcohol, ester and ketone compounds.
