Abstract
We hypothesized that these may be putative targets for C. collinus action and we tested this by exposing rat renal brush border membrane (BBM) as well as cultured kidney cells to a boiled decoction of C. collinus. Exposure to the C. collinus decoction resulted in significant inhibition of vacuolar t...

Abstract
Dipeptidyl peptidase IV is an ectopeptidase with multiple physiological roles including the degradation of incretins, and a target of therapies for type 2 diabetes mellitus. Divalent cations can inhibit its activity, but there has been little effort to understand how they act. The in...

Abstract
We synthesized the novel radioligand [(125)I]4-iodophenyl 1,4-diazaicyclo[3.2.2]nonane-4-carboxylate ([(125)I]CHIBA-1006), a iodine-derivative of the selective α7 nAChR agonist SSR180711, and studied the characterization of [(125)I]CHIBA-1006 binding to rat brain membranes. The assays of [(125)I]CH...

Abstract
We hypothesized that U73122 acts as an inhibitor of cardiac PLD activity by interference with PIP2. U73122 concentration-dependently inhibited PLD activity in rat myocardial membranes. The inhibitory effect of U73122 was significantly attenuated when assayed on solubilized PLD activity and was compl...
