Inhibition4

  • Loss of steroid-metabolite protection may allow lipid oxidation to cause persistent cell injury

    Where this hypothesis actsPerimenopausal participants; affected tissue remains to be identified

    What is proposedSuppress lipid-peroxidation chain reactions

    With whatSmall molecule

    HowUse a downstream radical-trapping compound, or restore mean steroid exposure when this restores steroid-metabolite-mediated chemical protection

    Possible resultPossible prevention of persistent cellular injury and stabilization of SPV_9

  • A lipid oxidation chain may sustain damage between gut and vascular tissue

    Where this hypothesis actsA self-sustaining damage loop between intestinal and vascular tissues in an ageing organism

    What is proposedBriefly suppress lipid peroxide formation in one tissue component

    With whatNot stated in the record

    HowIndependent methods of suppressing iron-dependent oxidation; specific interventions are not stated

    Possible resultPossible lasting interruption of the circulating damage chain and simultaneous barrier and vascular tissue recovery

  • Oxidation of treatment lipids may damage skin cells and slow recovery after friction and drying

    Where this hypothesis actsLiving keratinocyte membranes after lamellar lipid treatment and repeated friction and drying

    What is proposedSuppress lipid peroxidation

    With whatSmall molecule

    HowReplace linoleic acid in the formulation with an equimolar analogue deuterated at bis-allylic positions

    Possible resultPossible reduction in hydroperoxides and protein adducts, with improved recovery after repeated stress

  • Oxidation of a lipid carrier on skin may cause recurring damage as toxic products accumulate

    Where this hypothesis actsIn the residual film of an oxidizable lipid carrier on skin under ordinary sunlight exposure

    What is proposedSuppress lipid oxidation in the carrier film

    With whatNot stated in the record

    HowReplace the oxidizable carrier with an oxidation-resistant carrier at the same total dose, with comparable drug delivery, hydration, occlusion and light exposure

    Possible resultPossible reduction in repeated peaks of skin damage despite comparable tissue drug concentrations
