Abstract

|
|
|
Lauraceae is a family medicinal plant whose tubers possesses antimicrobial, and cytotoxic, such as antiparasitic and anti-inflammatory special effects and has been used for the medicine in the cure of hepatitis and rheumatism. The antimicrobial activities of bioactive compounds including one neolignan; kunstlerone (1) and two alkaloids include isocaryachine (2) and noratherosperminine (3) as well as crude hexane, methanol and dichloromethane extracts were evaluated. Additionally, the effect of compounds 1,2 and 3 were evaluated on A549, PC-3, A375, HT-29 and WRL-68 cell lines. In conclusion, kunstlerone 1 showed moderate cytotoxicity against various cancer cell lines such as A549, PC-3, A375, HT-29 and WRL-68, respectively with EC50 values of 28.02, 26.78, 33.78, 33.65 and 16.46 μg/mL. The crude methanol extract showed antigrowth activity against S. pyogenes II and B. cereus, with MICs of 256 μg/mL. The compounds kunstlerone (1), isocaryachine (2) and noratherosperminine (3) showed complete inhibition against P. shigelloides, with MIC ≤60 μg/mL compare to ampicillin, as a positive control, which showed antigrowth activity against P. shigelloides at MIC 10 μg/mL.
