Derivatives of cyclohexanol were screened for pharmacological effects on intact anesthetized rats, isolated guinea pig heart, isolated rat atria and isolated rabbit small intestine. All the compounds tested produced a hypotensive response and cardio-inhibitory effects varying from slight depression to complete arrest. On the basis of recovery from induced cardiac arrest none of the compounds appeared to be cardio-toxic. All the compounds produced inhibitory effects on the isolated small intestine in varying degrees. Methyl 3-hydroxy-2-o-tolylcyclohexylacetate and trans-3-oxo-2-o-tolylcyclohexylacetic acid were equally potent and the most effective in their cardiovascular effects whereas the ketal from glycerol and 2-o-tolylcyclohexylacetate was the most effective on the isolated rabbit small intestine. Studies of mechanism, employing the isolated rat atria, indicate an antagonistic effect between these compounds and calcium.
