Constituents of Mammea Americana L. VIII: Novel Structural Variations on the Mammein Theme and Antitumor Activity of Mammein and Related Coumarin and Phloroglucinol Derivatives

Antibacterial activity of crude extracts from Mexican medicinal plants and purified coumarins and xanthones

“…Various studies have previously shown the biological activities of some coumarins and xanthones (Finnegan et al, 1972;Sundaram et al, 1983;Iinuma et al, 1996;ReyesChilpa et al, 1997;Ojala et al, 2000;Itoigawa et al, 2001;Ito et al, 2002). However, this is the first report of antibacterial activity of these six compounds against Escherichia coli and Staphylococcus aureus (MSSA and MRSA).…”

“…However, this is the first report of antibacterial activity of these six compounds against Escherichia coli and Staphylococcus aureus (MSSA and MRSA). Calophyllum brasiliense and Mammea americana contain other types of coumarins and xanthones (Crombie et al, 1967;Finnegan et al, 1972;Finnegan et al, 1973;Ito et al, 2002), therefore, their antibacterial activity should be studied.…”

Novel Cytotoxic 4-Phenylfuranocoumarins from Calophyllum dispar

“…However, this deduction should not be directly extended to compounds 1 and 6 , where the acyl chain is probably issued from a chiral amino acid such as isoleucin . Furthermore, in this latter series, weak optical activities are reported for highly concentrated solutions. , …”

Susceptibility ofPorphyromonas gingivalisandStreptococcus mutansto Antibacterial Effect fromMammea americana

“…It also provides inhibitory activity against Mycobacterium tuberculosis [19] and molluscicidal properties against Biomphalaria glabrata [20]. Furthermore, antitumor activity has been reported, as well as some coumarin, phloroglucinol derivatives [21, 22], xanthones, and benzophenones [23]. Currently, there are few studies reporting the M. americana antimicrobial activity, specifically for oral bacteria.…”
