Abstract:
Two new peltogynoids, acanilol (1) and acanilol B (2), were isolated from the stem bark of Acacia nilotica (L.) Delile, together with the known triterpene lupenone. The structures of the new compounds were established on the basis of their spectral data, mainly UV, NMR, and mass spectrometry. The new compounds were tested as kinase inhibitors against CDK1, GSK3, CK1, and DYRK1A, and acanilol B was identified as a DYRK1A inhibitor, with an IC(50) of 19 microM.
