Calcium-antagonists and islet function X. Effect of suloctidie.

Suloctidil (0.5 to 5.0 micrometer) inhibits insulin release evoked by glucose or alpha-ketoisocaproate in pancreatic islets. The drug also inhibits basal and glucose-stimulated 45calcium net uptake by the islets. In an artificial system, suloctidil inhibits A23187-mediated calcium translocation. It is proposed that the inhibitory action of suloctidil upon islet function may be due to interference with B-cell native ionophoretic system(s).
