    摘要: The present invention involves use of the compounds narciclasine (2a) and 7-deoxy-narciclasine (2c), which are obtained via isolation from the medicinal plant species Narcissus (Amaryllidaceae), as precursors in a novel synthesis method in which each of these compounds are selectively hydrogenated to produce trans-dihydronarciclasine (1a) and 7-deoxy-trans-dihydronarciclasine (1c). Also described herein is a novel synthesis method for producing sodium narcistatin (11) from narciclasine (2a). Further described herein are certain novel 3,4-cyclic phosphate prodrugs, including sodium-7-deoxynarcistatin (8), sodium-7-deoxy-transdihydronarcistatin (9), and sodium transdihydronarcistatin (10).

    摘要: The present invention relates to a compound of formula (1), (2) or (3) having the following structures: Formula 1, 2, 3 wherein X, Y, and Z are independently C or N; A is a direct bond, CH2 or NH;B is a direct bond or NH; n= 0-2; R1 is H, optionally substituted C1-4191 alkyl, C3-7191 cycloalkyl, halogen, cyano, nitro, aryl, or alkylaryl; R2 is H, C1-4191 alkyl, or alkoxy C1-4191 alkyl;or R1 and R2 are taken together to form an unsaturated 6-membered aromatic or heterocyclic ring containing one or two heteroatoms fused to the pyridone; R3 is a direct bond, H, C1-4191 alkyl, substituted C1-4191 alkyl, C3-7191 cycloalkyl, aryl or alkylaryl; R4 is a direct bond or H; R5 is C1-4191 alkyl or aryl; R6 and R7 are independently H or C1-4191 alkyl; R8 and R9 are independently H, C1-4191 alkyl, or tert-butoxycarbonyl or R8 and R9 are taken together with the nitrogen to which they are attached and form optionally, unsubstituted, substituted, fused or unsaturated 5-,6-,7-membered heterocycles containing one or two heteroatoms wherein said substituents are selected from the group consisting of hydroxyl, hydroxymethyl, carboxymethyl, carboxy, methoxy, and tert-butoxy;as (R)-enantiomers, (S)-enantiomers or a racemate in the form of a free base or a pharmaceutically acceptable salt or solvate thereof.
