  • Furthermore, the effect of pulsatile infusion (six pulses; 10 min on, 30 min off) of low doses of the following three progestins [5 beta-pregnan-3 beta-ol-20-one (pregnanolone), 5 alpha-pregnan-3 alpha-ol-20-one (3 alpha-5 alpha-P), and 20 alpha-OH-P] into the hypothalamus of does using push-pull cannulae were examined in Exp III [16].
  • The reduced uptake of pregnanolone in cerebellum, cortex and hippocampus (after 2.0 g kg(-1)) was not due to a corresponding change in serum concentration [17].
  • In membranes from cerebellum, there was little overall change in pregnanolone potency although the effects of threshold concentrations were increased [18].
  • A similar reduction of pregnanolone tissue concentrations was only found in brain stem and striatum [17].
  • CONCLUSIONS: Eltanolone induced no significant inotropic effect on rat myocardium [19].

Gene context of ELTANOLONE

  • Finally, the neuroactive steroid pregnanolone [(3alpha,5beta)-3-hydroxypregnan-20-one] produced anesthesia (loss of righting reflex) in VDAC-1- and VDAC-3-deficient mice, and there was no difference in the recovery time between the VDAC-deficient mice and wild-type controls [26].
  • In this connection, cellular radiolabeling with [3H] pregnanolone (3 alpha-hydroxy-5 alpha-pregnane-20-one) revealed bFGF to be a potent inhibitor of the steroidogenic enzyme 17 alpha-hydroxylase/17-20-lyase [27].
  • Sub-hypnotic doses (7.5 and 12.5 mg/kg, i.p.) of pregnanolone, administered 10 min before GHB, dose-dependently facilitated the expression of GHB-induced LORR in GHB-R male rats [28].
  • Following application of the steroids 5alpha-pregnan-3alpha,21-diol-20-one (5alpha-THDOC), alphaxalone and 5beta-pregnan-3alpha-ol-20-one (pregnanolone) hyperpolarizing PSPs developed into biphasic responses consisting of an early hyperpolarizing and a late depolarizing PSP sequence [29].
  • Myocardial effects of eltanolone in hamsters with hypertrophic cardiomyopathy [30].
