    The synthesis of spermine analogs of the shark aminosterol squalamine
    摘要:
    Aminosterols isolated from the dogfish shark Squalus acanthias are promising therapeutic agents in the treatment of infection and cancer. One of these, MSI-1436, has been shown to possess antimicrobial activity slightly better than squalamine. In this study, a series of analogs of MSI-1436 have been synthesized from stigmasterol. The 7alpha-hydroxy substituent of MSI-1436 was either omitted or the stereochemistry modified to the 7beta position. Also, analogs of MSI-1436 with 24-sultate, 24-amino, and 24-hydroxy substituents were synthesized in order to assess the importance of the side chain functional group on antimicrobial activity. All of the analogs possess significant antimicrobial activity, suggesting that substitution at C7 and C24 of the aminosterols plays a minor role in their antimicrobial potency.

    sterols can undergo various chemical reactions e.g., oxidation, dehydrogenation, dehydration and polymerisation. The objectives of this study are to prove the existence of dimers and to quantitatively analyse the dimers (3β,3′β-disteryl ethers). Sterol-rich samples were heated at 180 °C, 200 °C and 220 °C for 1 to 5 h. Quantitative analyses of the 3β,3′β-disteryl ethers were conducted using liquid

    hydroximino on ring A and B displayed remarkable distinct cytotoxicities against a diversity of cancer cell types. Presence of an oxime group on ring B and a hydroxy on ring A or B resulted in a higher cytotoxicity than other structural motifs. In addition, a cholesterol-type side chain at position 17 was required for the biological activity. Our findings provide new evidence showing the relationship

Whatever the cells considered, dose dependent cytotoxic effects of 7KC were observed whereas no or slight effects of ferulic acid were found. With spinasterol and schottenol, no or slight effects on cell growth were detected

    A method is described for stereoselectively reducing an unsaturated alkyl ketone substituent attached to a fused ring base. In this method, the unsaturated alkyl ketone reacts with a chiral oxazaborolidine reagent. This reaction stereoselectively reduces the unsaturated alkyl ketone to an unsaturated alkyl alcohol. The unsaturated alkyl alcohol can be further reduced, if desired, to produce a saturated alkyl alcohol. The fused ring base can be, for example, a steroid ring base or a base of a vitamin D analog. The process in accordance with the invention can be used with an alkeneone substituent (e.g., a 22-ene-24-one substituent) or an alkyneone substituent (e.g., a 22-yne-24-one substituent) on a steroid ring base to make squalamine or other useful aminosterol compounds and intermediates for making aminosterol compounds.
    描述了一种用于立体选择性地还原连接到融合环基的不饱和烷基酮取代基的方法。在这种方法中,不饱和烷基酮与手性氧化硼腙试剂发生反应。这种反应会将不饱和烷基酮立体选择性地还原为不饱和烷基醇。如果需要,可以进一步还原不饱和烷基醇,以产生饱和烷基醇。融合环基可以是类固醇环基或维生素D类似物的基。根据本发明的工艺可以用于具有烯酮基取代基(例如,22-烯-24-酮基)或炔酮基取代基(例如,22-炔-24-酮基)的类固醇环基,以制备鲨碱或其他有用的氨基类固醇化合物和用于制备氨基类固醇化合物的中间体。
