In current study, we report efficient and clean procedure for preparing mycosporine-like amino acids (MMAs) analogs and evaluate their ultraviolet absorbance properties and antioxidant activities. The ultraviolet radiation absorbance patterns of the compounds were recorded and then used to define their molar absorptivities. The antioxidant activities were assessed using 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging and superoxide radical scavenging assays. Eight of nine compounds showed good activity against superoxide radicals, as only one of the analogs exhibited a measurable IC50 in the DPPH assay. © 2013 Wiley Periodicals, Inc.
