Abstract
秋水仙素經五步驟反應合成了N-甲基-N-去乙醯-甲硫基秋水仙，為增強其水溶性，取該化合物與葡萄糖及甘露糖反應，合成了新化合物：N-甲基 -N-（D-葡糖基）-N-去乙醯-甲硫基秋水仙(7)及N-甲基-N-（D-甘露糖基）-N-去乙醯-甲硫基秋水仙(8)；將此兩化合物乙醯化，得到了 N-甲基-（四-氧-乙醯基-D-葡糖基）-N-去乙醯-甲硫基秋水仙(9)及N-甲基-N-（四-氧-乙醯基-D-甘露糖基）-N-去乙醯-甲硫基秋水仙(10)，以NMR分析其結構，其生理活性尚待試驗。
Four new glycosyl derivatives 7-10 of N-methyl-methylthiocblchicine have been prepared from colchicine through an intermediate N-methyl-N-deacetyl-methylthiocolchicine (6) and ex-amined by NMR and MS techniques. The water solubility of new compounds is increased due to the glycosyl mioety.
