Antifungal constituents from the Chinese moss Homalia trichomanoides.[Pubmed: 17191927]
Bioautographic assay on TLC plates was adopted to guide the fractionation of the Et2O extract of Homalia trichomanoides (Hedw.) B. S. G., which led to the isolation of the novel p-terphenyl derivative trichomanin (= 4,4''-dihydroxy-1,1':4',1''-terphenyl-2',3',5',6'-tetrayl tetrakis(phenylacetate); 1), together with five known compounds: 3alpha-methoxyserrat-14-en-21beta-ol (2), 3beta-methoxyserrat-14-en-21beta-ol (3), 3beta-methoxyserrat-14-en-21-one (4), atranorin (5), and methyl 2,4-dihydroxy-3,6-dimethylbenzoate (6). Their structures were determined on the basis of spectral data (1D- and 2D-NMR, MS), X-ray crystallographic analysis, and chemical transformation. Compounds 3, 5, and 6 exhibited antifungal activity against Candida albicans, with minimum inhibitory doses (MID) of 2.0, 2.0, and 0.6 microg, respectively.
