Three previously undescribed indole alkaloids, named latifolianine A (1) and latifoliaindoles A and B (2 and 3), along with 10 known compounds (4-13), were isolated from the heartwood of Nauclea latifolia. Their structures were elucidated based on the analysis of their NMR and MS data. Latifolianine A (1) represents an unusual and unprecedented monoterpene indole alkaloid unit condensed with an ursane-type pentacyclic triterpenoid moiety. Plausible biogenetic routes toward latifolianine A (1) and latifoliaindoles A and B (2 and 3) were proposed. All the isolates were assessed in vitro for their inhibitory effects on Haemophilus influenzae. Naucleidinal (7) exhibited potent antibacterial activity (MIC value of 3.1 µg/mL) as compared to a reference drug, ciprofloxacin (MIC value of 1.6 µg/mL).
