The present invention relates to the use of specific steroid derivatives in the preparation of medicaments for the treatment or prevention and/or amelioration of disorders relating to pathological processes in lipid rafts.
A new class of artificial ionophores has been rationally designed and synthesized linking to a tetrafunctionalized L-treitol spacer two rigid hydrophobic 3beta-hydroxy-5alpha-23,24-bisnorcholanic units and two flexible hydrophilic oligo(ethylene glycol) chains. Compounds 1a and 1b were incorporated into phospholipid vesicles and shown to facilitate Na+-transport. (C) 2003 Elsevier Ltd. All rights reserved.

toxicity under normal conditions. In the present study, a library of 14 GSDs was synthesized and screened against PANC-1 human pancreatic cells. Among tested compounds, GSD-11 showed the most potent activity with PC50 a value of 0.72 μM. It also inhibited pancreatic cancer cell migration and colony formation in a concentration-dependent manner. A mechanistic study revealed that this compound can inhibit the

The synthesis of five steroid-oligo(ethyleneglycol) conjugates (1–5) has been accomplished starting from commercially available epi-androsterone (8) and known 3β-[(tert-butyldiphenylsilyl)oxy]-5α-23,24-bisnorchol-16-en-6α,7β,22-triol (27). The synthetic strategy was based on a convergent approach including stereoselective C-17 side chains construction and standard couplingreactions. The activities
