According to a study published by "Scientific reports", the plant Dendrobium crepidatum was used to isolate two new indolizidine alkaloids, crepidatumines A (1) and B (2). These compounds were identified alongside the stereoisomer of dendrocrepidine B (3) and the known analog dendrocrepine (4). The structural analysis showed that compound (1) possesses a (5/6/6/5) tetra-hetero-cyclic ring system. Additionally, compound (2) contains a tricyclic system featuring an unusual bridged ring. Biological evaluation of the isolated substances revealed that dendrocrepine (4) displayed a potent hypoglycemic effect in vitro.
