|Abstract:||© 2018 Natural Product Incorporation. All Rights Reserved. Bioassay-guided fractionation of the aerial parts of Dasymaschalon echinatum led to the isolation of five known aristolactams; aristolactam AII (1), aristolactam BII (2), piperolactam A (3), piperolactam C (4), and goniopedaline (5), together with two aphorphine alkaloids; duguevalline (6) and noraristolodione (7) and two amide derivatives; asperphenamate (8), and N-benzoyl-L-phenylalaninol (9). Alkaloids 2 and 7 were isolated for the first time from the Dasymaschalon genus. The anti-HIV 1 reverse transcriptase (RT) activity of all isolated compounds was determined. Except for aristolactam BII (2), this is the first report of the anti-HIV 1-RT activity of compounds 1 and 3-9. Compounds 1, 3, 5, 6 and 8 showed weak anti-HIV 1-RT inhibitory activity with IC50 ranging from 112.74 to 225.55 M.|
