Cytotoxicity of aporphines in human colon cancer cell lines HCT-116 and Caco-2: An SAR study
摘要:
A series of synthetic aporphine derivatives structurally related to domesticine and nantenine (ring A, N6 and ring C truncated analogs), was evaluated in MTS cytotoxicity assays against the human colon cancer cell lines, HCT-116 and Caco-2. In general, the C1 position of ring A is tolerant of alkoxy substituents as well as a benzoyl ester functionality. Other modifications evaluated resulted in a decrease in cytotoxic activity. The most potent compounds identified had IC(50) values in the range 23-38 mu M, comparable to the known cytotoxic agent, etoposide. (C) 2011 Elsevier Ltd. All rights reserved.

Synthesis of optically active aporphine and morphinandienone alkaloids via p-quinol esters
Lead tetraacetate oxidation of N-trifluoroacetylnorcodamine (5) in (S)-(+)-2-phenylpropionic acid gave a diastereomeric mixture of two p-quinol acylates, which were easily separated to enantiomerically pure 6a and 6b. Treatment of the chiral quinol acylates (6a) and (6b) with trifluoroacetic acid in CH2Cl2 at room temperature afforded (1R)-(−)-6-trifluoroacetylwilsonirine (7a) and , respectively. Saponification
