Antimicrobial and anti-tubercular activities of isolates and semi-synthetic derivatives of lichen Ramalina leiodea (Nyl.) Nyl.,
Journal of the Serbian Chemical Society,
84(6): 555-562
The chemical investigation of lichen Ramalina leiodea (Nyl.) Nyl. yielded five known metabolites, i.e., usnic acid (1), ethyl everninate (2), scrobiculin (3), methyl 2,6-dihydroxy-4-methylbenzoate (4) and 4-[(2-hydroxy-4-methoxy-6-propylbenzoyl)oxy]-2-methoxy-6-propylbenzoic acid (5). To develop compound libraries on 4, a series of semi-synthetic derivatives was prepared (4a––e). All the metabolites and semi-synthetic analogues were screened for antimicrobial and anti-tubercular activities. The …
