Incubation of the tryptic digest with snake venom phosphodiesterase gave (32) P-labeled products that migrated on electrophoresis on cellulose plates to the cathode, indicating covalent linkage of (32) P-labeled dAMP residues to a tryptic peptide.
Formic acid/diphenylamine depurination (Burton reaction) of the [alpha-(32) P] dATP-labeled peptide-oligonucleotide complexes caused a transfer of the labeled phosphate from dAMP to the peptide.

Pretreatment with diphenylamine 2,2'-dicarboxylic acid, a Cl- channel blocker, significantly reduced both PGE2-induced ISC responses, while pretreatment with amiloride, a Na+ channel blocker, did not exert any effect.
Forskolin, an adenylate cyclase activator, and 3-isobutyl-dihydro-testosterone-1-methyl-xanthine, a cAMP phosphodiesterase inhibitor, mimicked the ISC response to PGE2 while MDL12330A, an adenylate cyclase inhibitor, completely abolished the PGE2-induced ISC.

It is proposed that the inhibition of cyclic AMP-phosphodiesterase-activity by amoscanate and derivatives - resulting in accumulation of cyclic AMP - might subsequently lead to disturbances in the regulation of metabolic areas like glycogen metabolism which are controlled by cyclic AMP-dependent protein kinases.

In this study, the effect of two concentration ranges of the cAMP phosphodiesterase inhibitor, caffeine, on alveolar macrophage function was investigated by measuring survival rate, superoxide anion production and DNA fragmentation.
However, at higher concentrations (5-20 mM), at which the viability was higher than the control, a significant increase in both superoxide production and DNA degradation, as judged by agarose gel and diphenylamine reaction, was obtained for 3 and 24 h of culture.

Addition of the phosphodiesterase inhibitor IBMX induced an increase in the short-circuit current (Isc) equivalent to the net increase in Cl- secretion.
The Isc was inhibited by diphenylamine decarboxylate (DPC; Cl- channel blocker), bumetanide (basolateral Na+/K+/2Cl- cotransporter), BaCl2 (basolateral K+ channel) and Cl- free buffer in both segments and indomethacin (cyclo-oxygenase inhibitor) in colon alone.

Intracellular cAMP levels were raised by addition of either the phosphodiesterase inhibitor theophylline (3 X 10 (-3) M) or the adenylate cyclase activator forskolin (10 (-5) M) to the serosal bathing solution.
Estimates of the conductive flux, obtained by either reducing simultaneously mucosal [Cl-] and [HCO3-] or lowering [Cl-] alone in the presence of a blocker of anion exchange (diphenylamine-2-carboxylate), indicate that elevation of intracellular cAMP inhibited the anion exchanger by approximately 50%.

The PGE2-stimulated Cl secretion could be inhibited by the presence of ouabain or furosemide in the basolateral solution or diphenylamine-2-carboxylate in the apical solution.
The PGE2-stimulated Cl secretion was enhanced by the phosphodiesterase inhibitor, theophylline, indicating that the effect of PGE2 was caused by an increase in the intracellular cAMP level in the gland cells.

Thus, radiotracer efflux measurement appears to be a sensitive assay method to study stimulus-secretion coupling in oocytes. 125I efflux was suppressed by the C1- channel blocker diphenylamine-2-carboxylate, but was insensitive to bumetanide.
