Isomalyngamide A (1) and A-1 (2) were isolated from the Taiwanese Lyngbya majuscule and the latter structure was elucidated by a combination of NMR spectroscopic analysis and HRESIMS measurement. We report the isolation of isomalyngamide A (1), discovery of isomalyngamide A-1 (2) and their synthetic analogs (3-9), which are further demonstrated to have therapeutic potential against tumor cell migration at the level of nanomolar to micromolar ranges, perhaps, by inactivating the expression of p-FAK, FAK, p-Akt and Akt through β1 integrin-mediated antimetastatic pathway.

In continuation of our efforts to find new antimicrobial compounds, series of fatty N-acyldiamines were prepared from fatty methyl esters and 1,2-ethylenediamine, 1,3-propanediamine or 1,4-butanediamine. The synthesized compounds were screened for their antibacterial activity against Gram-positive bacteria (Staphylococcus aureus, Staphylococcus epidermidis), Gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa) and for their antifungal activity against four species of Candida (C. albicans, C. tropicalis, C. glabrata and C. parapsilosis). Compounds 5a (N-(2-aminoethyl)dodecanamide), 5b (N-(2-aminoethyl)tetracanamide) and 6d (N-(3-aminopropyl)oleamide) were the most active against Gram-positive bacteria, with MIC values ranging from 1 to 16 μg/mL and were evaluated for their activity against 21 clinical isolates of methicillin-resistant S. aureus. All the compounds exhibited good to moderate antifungal activity. Compared to chloramphenicol, compound 6b displayed a similar activity (MIC50= 16 μg/mL). A positive correlation could be established between lipophilicity and biological activity.

Three, new, fully synthetic glycosylated isomalyngamide A analogs 4-6 were prepared and evaluated for their anti-migratory activities in human breast cancer cells. The results of the study show that two glycosylated derivatives 4 and 5, containing mannose and galactose appendages, suppress metastatic events (e.g., migration, invasion and adhesion) in human breast adenocarcinoma MDA-MB-231 cells at "nontoxic" concentration levels. In contrast, derivative 6 that contains a lactose moiety, displays a less potent activity. The findings show that monosaccharide rather than disaccharide appendages to the isomalyngamide A backbone more greatly influence cell migration and invasive ability. Evidence has been gained for a mechanism for inhibition of metastatic activities in MDA-MB-231 cells by 4 and 5, involving inactivation of the expression of p-FAK and paxillin through the integrin-mediated antimetastatic pathway.
