In particular, 12b showed the highest cytotoxic potency of the series, including drug-resistant Bel7402 cells, but had minimal effect on normal hepatic LO2 cells. Despite containing the well-established cyclic triester core of iron-binding natural products such as enterobactin, bacillibactins E and F (1 and 2) are the first bacterial siderophores that contain nicotinic and benzoic acid moieties. The structure–activity relationship results suggested that the presence of a succinic acid or glutaric acid linker, a piperazinyl amide terminus, and lipophilic cations are all beneficial for promoting cytotoxic activity. Its planar structure was elucidated by spectral analyses, mainly 2D NMR, and the absolute configurations of the α-amino acid moieties were determined by degradation reactions followed by chiral-phase HPLC analyses. A structure-guided isolation procedure yielded 16 myrsinane (11a–h, 12, and 13) and premyrsinane esters (14a–c and 15a–c), along with four 4β-phorbol esters (16a–c and 17) that showed inhibitory activity against chikungunya virus replication. This approach utilizes an ultrafiltration-based LC-PDA-MS/MS-guided DNA-binding assay in combination with the (i) Global Natural Products Social Molecular Networking, (ii) Dictionary of Natural Products, and (iii) SciFinder platforms to identify DNA binders in complex chemical mixtures. The use of molecular networking coupled to unsupervised substructure annotation (MS2LDA) indicated the presence of new premyrsinane/myrsinane diterpene esters in the E. cupanii fractions. Hence, natural products, as is the case for other therapeutic areas, continue to be a promising source of structurally diverse new anti-RNA virus therapeutics. The metabolite profile obtained guided the isolation of 21 compounds, among which two sesquiterpenes (8 and 9) and one diterpene (10) were found to be new. Intrathecal (i.t.)
