echinochloa

Mesotrione 是一种苯甲酰环己二酮类除草剂，是一种竞争性羟基苯基丙酮酸双加氧酶酶抑制剂。它对玉米作物具有选择性，它在易感作物中代谢速度快，耐受性较高。

PPO-IN-18 (Compound g13) 是一种原卟啉原氧化酶（PPO）抑制剂，可有效抑制稗草PPO（EcPPO），其IC50为0.109 μM。PPO-IN-18 对稗草、牛筋草、稷、牵牛、藜和苘麻具有除草活性，在150-300 g ai/ha的剂量下，对作物没有显著毒性。

NtPPO-IN-1 (Compound A4) 是Nicotiana tabacum PPO (NtPPO) 的强效抑制剂，Ki值为9.05 nM。对Setaria viridis、Echinochloa crus-galli、Digitaria sanguinalis、Amaranthus retroflexus、Abutilon theophrasti和Portulaca oleracea具有显著除草活性，而对玉米和水稻的损伤在150 g a.i./ha时为30-50%。

PPO-IN-13 (compound B16) 是一种有效的原卟啉原 IX 氧化酶 (PPO) 抑制剂，其Ki值为32.14 nM。在 37.5 g a.i./ha 的浓度下，PPO-IN-13 对稗草 (Echinochloa crusgalli)、马唐 (Digitaria sanguinalis)、狗尾草 (Setaria faberii)、苘麻 (Abutilon juncea)、反枝苋 (Amaranthus retroflexus)、和马齿苋 (Portulaca oleracea) 展现出广谱且出色的除草效果。

Methyl orsellinate is a phytotoxic compound, it exhibits antifungal activity, it can cause significant inhibition of radicle growth of Amaranthus hypochondriacus and Echinochloa crus-galli, interact with bovine-brain calmodulin and inhibit the activation of the calmodulin-dependent enzyme cAMP phosphodiesterase. Methyl orsellinate can inhibit PTP1B activity with 50% inhibitory concentration values of 277 +/- 8.6 microM, the selective inhibition of PTP1B has been widely recognized as a potential drug target for the treatment of type 2 diabetes and obesity, methyl orsellinate may can treat the type 2 diabetes and obesity.
