  Synthesis of (25R)-5α-Cholestane-3β,6β,15α,16β,26-pentol, a Cytostatic Starfish Steroid

  摘要：

  The synthesis of (25R)-5 alpha-cholestane-3 beta,6 beta, 15 alpha,16 beta,26-pentol (1a), a marine cytostatic steroid, has been achieved in 13 steps (7.8% overall yield) starting from commercially available diosgenin (2). A key step in the synthesis was the dimethyldioxirane oxidation of the enolsilane 16 to introduce the 15 alpha-hydroxy group in the D ring.

  摘要：

  Chlorogenin 3-O-beta-chacotrioside (1) and its 6 alpha-O-acyl derivatives (2-6) were concisely synthesized. Introduction of a hydroxl or acyloxy group onto the C-6 of the steroidal aglycone of dioscin decreased significantly the cytotoxicity of the parent saponin (dioscin).

  Naturally occurring spirostanol saponins bear a chacotriose, alpha-L-rhamnopyranosyl-(1-->2)-[alpha-L-rhamnopyranosyl-(1-->4)]-beta-D-glucopyr anose residue as the oligosaccharide moiety which is believed to be important for biological activity. Herein the development of a concise, combinatorial method for the synthesis of two series of glycan variants at the 2' and/or 4' positions of chacotriose is

  The occurrence of highly pathogenic avian influenza virus H5N1 highlights the urgent need for new classes of antiviral drugs. Theoretically, each of steps in influenza viral life cycle can be a target of antiviral therapeutics. However, up to date, no licenced entry inhibitor drug is available for H5N1 or any other influenza viruses. Our strategy for developing new anti-influenza therapeutics is to target the interaction between HA and sialic acid which is influenza viral receptor presented on host cell surface. Here, based on our previously discovered small molecule inhibitor saponin 1, intensive SAR studies around the sugar chain and aglycone were conducted. The results showed that both the chacotriosyl residue and the chlorogenin moiety of active compound 1 are important for the antiviral activity, although several subtle modifications can be made on particular positions.

  The occurrence of highly pathogenic avian influenza virus H5N1 highlights the urgent need for new classes of antiviral drugs. Inhibition of H5N1 entry into cells may be an effective strategy. We report the first three small molecule inhibitors saponins with 3-O-beta-chacotriosyl residue, which Showed potent inhibitory activity with IC50 of 7.22-9.25 mu M. The subsequent SAR studies showed the 3-O-beta-chacotriosyl residue was essential for the activity, and the aglycone structure also affected the activity.
