The syntheses of 5-pregnen-3β-ol-20-one esters and 3,5-cyclo-pregnan-6β-ol-20-one derivatives are described. Animal tests (inflammatory granuloma pouch) gave the following results: the salicylate and benzoate of 5-pregnen-3β-ol-20-one possess significant anti-inflammatory action, equivalent to that of Antiflamisonum The other esters of 5-pregnen-3β-ol-20-one (chloroacetete, trichloroacetate, furan-2'-carboxylate, p-toluenesulfonate, phthalate)and 3,5-cyclo-pregnan-6β-ol-20-one were found to be somewhat more...

The correlation between measured values and calculated valeus for logP of cinnamamide compounds was discussed. It was found that the result obtained by means of HPLC might express relative magnitude of the partition coefficients of cinnamamide compounds and the π-method could estimate logP...

In this paper, the partition coefficients of 17 α-substituted compounds and 9 β-substituted compounds were masured by means of flask shaking or HPLC method, and were calculated by fragment method or π-method respectively.

It was found that the result obtained by means of HPLC might express relative magnitude of the partition coefficients of cinnamamide compounds and the π-method could estimate logP cinnamamide compounds more correctly than fragment method.

The anticonvulsant activities of thirty-eight cinnamamides have been used to formulate quantitative structure-activity relationships. The correlations indicate that the activity of these series of compounds is parabolically related to the partition coefficients (log P octanol/water) of the compounds. Hammett σ constants and steric parameter (MR) of the substituents can significantly improve the correlations. The equation indicates that the substituents with electron Withdrawing effect and small steric parameter...

The anticonvulsant activities of thirty-eight cinnamamides have been used to formulate quantitative structure-activity relationships. The correlations indicate that the activity of these series of compounds is parabolically related to the partition coefficients (log P octanol/water) of the compounds. Hammett σ constants and steric parameter (MR) of the substituents can significantly improve the correlations. The equation indicates that the substituents with electron Withdrawing effect and small steric parameter will increase anticonvulsant activity of cinnamamide. The correlation analysis of twenty N-cinnamoyl piperidines out of the thirty-eight cinnamamides gives a similar equation.
