Effect of the Chromone Core Substitution of Dirchromone on the Resultant Biological Activities

Dirchromone is a bioactive vinyl sulfoxide-bearing chromone first isolated from the shrub Dirca palustris. Altogether, 32 of its derivatives were prepared to assess the effect of substitution of its chromone core upon activities against cancer cell lines, Gram-positive bacteria, and fungi (such as Candida albicans). All compounds were synthesized following a synthetic strategy involving Pummerer and soft-enolization Baker-Venkataraman...
