Bioactivity

• In Vitro:
  Diphenhydramine blocks tetrodotoxin-sensitive (TTX-S) and tetrodotoxin-resistant (TTX-R) sodium currents with K(d) Values of 48 mM and 86 mM, respectively at a holding potential of -80 mV. Diphenhydramine shift the conductance-voltage curve for TTX-S sodium currents in the depolarizing direction but has little effect on that for TTX-R sodium currents. Diphenhydramine causes a shift o the steady-state inactivation curve for both types of sodium currents in the hyperpolarizing direction. Diphenhydramine produces a profound use-dependent block whe the cells are repeatedly stimulated with high-frequency depolarizing pulses. Diphenhydramine induces apoptosis in a dose- and time-dependent manner In both CCRF-CEM and Jurkat cell lines, whereas Cimetidine fails to induce significant effects at similar concentration . Diphenhydramine-induced apoptosis is evaluated in terms of morphology, flow cytometry, an the release of cytochrome c to the cytosol. Diphenhydramine inhibits cell proliferation without inducing apoptosis in human peripheral blood mononuclear cells. Diphenhydramine (500 nM) significantly reduce the baseline firing o the periaqueductal gray neurons without a significant effect o the frequency of postsynaptic potentials. Diphenhydramine at high concentration inhibits periaqueductal gray neurons, but at low concentration it has no effect o the baseline-firing rate and it block the response to neurotensin and tomedial preoptic nucleus stimulation.
