phytotoxicity

Simazine (Tafazine) is a chlorotriazine herbicide and pesticide. Simazine may lead to testicular degeneration, neuroendocrine disruption, mammary cancer, and fetal developmental delays.

Usaramine (Mucronatine) demonstrates phytotoxicity against Lactuca sativa var. Carrascoy (lettuce) assessed as inhibition of seed germination at 50 ug/cm2 after 24 hr.

Tulipalin A (α-methylene-γ-butyrolactone) (2-Methylenebutyrolactone) which has some phytotoxicity is a natural compound extracted from Tulipa gesneriana.

Regiolone demonstrates phytotoxicity. Regiolone also has anti-proliferative and apoptotic activities, it can induce apoptosis in MCF-7 cells through the caspase-3 independent pathway.

Isololiolide has phytotoxicity, it inhibited seedling growth of cress and barnyard grass. It also showed in vitro activity against both trypomastigote and intracellular amastigotes of Trypanosoma cruzi, with IC50 values of 32 μM and 40 μM, respectively. I

Destruxin B2 is a cyclic hexadepsipeptide mycotoxin that has been found in M. anisopliae and has antiviral, insecticidal, and phytotoxic activities.1,2,3 It inhibits secretion of hepatitis B virus surface antigen (HBsAg) by Hep3B cells expressing hepatitis B virus (HBV) DNA (IC50 = 1.3 μM).1 Destruxin B2 is toxic to Sf9 insect cells in an electric cell-substrate impedance sensing (ECIS) test with a 50% inhibitory concentration (ECIS50) value of 92 μM.4 It is also phytotoxic to B. napus leaves.3 |1.
