Oxindole alkaloids from Alstonia macrophylla

, : Oxindole alkaloids from Alstonia macrophylla. Phytochemistry (Oxford) 41(1): 313-315

Two new oxindole alkaloids, N-b-demethyialstophyllal oxindole and alstonal, together with three known alkaloids, N-b-demethylalstophylline oxindole, alstonisine and talcarpine, have been isolated from the bark of Alstonia macrophylla. Structures of the alkaloids were assigned by spectral methods.

The observation of complex receptor behaviors has shown how ligands can have multiple efficacies and can also differentially stimulate certain cellular signaling pathways over others (i.e., biased signaling). Conventional pharmacological assays (u...
