Dansylcadaverine (DCA), diphenylamine (DPA), and lidocaine (LID) inhibited NK activity of nylon wool-purified and large granular lymphocyte (LGL)-enriched cell preparations.
All three amines that inhibited NK activity also reduced the intracellular concentration of the lysosomal enzyme beta-glucuronidase without affecting the activity of the cytoplasmic enzyme lactate dehydrogenase.

Exposure of LLC-PK (1) cells to 1 mM H (2) O (2) resulted in the following: depletion of intracellular ATP content; DNA damage; lipid peroxidation; and a loss of membrane integrity to both small molecules, e.g., trypan blue, and macromolecules, e.g., lactate dehydrogenase (LDH), and cell death.
Substitution of Cl (-) by isethionate or the inclusion of certain Cl (-) channel blockers, e.g., diphenylamine-2-carboxylate (DPC), 5-nitro-2-(3-phenylpropylamino). benzoate (NPPB), and niflumic acid, prevented the H (2) O (2)-induced loss of membrane integrity to LDH.

We investigated the cytotoxicity of 18 acidic NSAIDs (3 salicylic acids, 3 anthranilic acids, 6 arylacetic acids, 6 arylpropionic acids) to freshly isolated rat hepatocytes as assessed by the NSAID-induced leakage of lactate dehydrogenase (LDH) in order to determine structural requirements for the direct hepatotoxicity of the NSAIDs.
Because the cytotoxic NSAIDs were of two types as classified by their "skeleton," diphenyl and diphenylamine, we tested the cytotoxicity of the compounds.

The leakage of two intracellular enzymes, lactate dehydrogenase (LDH) and glutamic oxaloacetic transaminase (GOT) were compared as indicators of cell damage.

Of several compounds tested as potential blockers of ATP transporters or channels only glibenclamide (100 microM) and diphenylamine-2-carboxylate (500 microM), which block the cystic fibrosis transmembrane conductance regulator, caused any change: both reduced the effect of AMPA without changing the effects of N-methyl-D-aspartate and (only glibenclamide tested) kainate.

The duodenal contents was explored by microscopy of the sediment and biochemistry which included analysis in the vesicular and liver portions of the concentrations of phospholipids, activity of phospholipases A and C as well as measurements of creatine kinase, lactate dehydrogenase, alkaline phosphatase, C-reactive protein and of the diphenylamine index.
