The extracts of five Cambodian medicinal plants (Aganosma marginata, Dracaena cambodiana, Harrisonia perforata, Hymenodictyon excelsum and Vernonia cinerea) were evaluated in vitro for their cytotoxic activity against HT29 colon adenocarcinoma cells and HepG2 hepatoma cells, using the MTT assay. Among

The hypothetical genes of Methylobacterium dichloromethanicum DM4, METDI 2671 (bioD2), and METDI 2680 located within the chromosomal fragment (126 kb) associated with dichloromethane (DCM) degradation have been studied. The reverse transcription polymerase chain reaction method (RT-PCR) showed the presence of

The phytoalexin cyclobrassinin is a plant defense that has additional importance since it inhibits brassinin hydrolase, a phytoalexin detoxifying enzyme produced by the plant pathogen Alternaria brassicicola. Hence, the 1,3-thiazino[6,5-b]indole scaffold of cyclobrassinin has great application as a lead structure
