Design and synthesis of novel ureido and thioureido conjugated hydrazone derivatives with potent anticancer activity

BMC Chemistry, 2022
Background Compounds possessing urea/thiourea moiety have a wide range of biological properties including anticancer activity. On the other hand, taking advantage of the low toxicity and structural diversity of hydrazone derivatives, they are presently ...

Silicon and Nitrate Differentially Modulate the Symbiotic Performances of Healthy and Virus-Infected Bradyrhizobium-nodulated Cowpea (Vigna unguiculata), Yardlong Bean (V. unguiculata subsp. sesquipedalis) and Mung Bean (V. radiata)

Plants, 2017
The effects of 2 mM silicon (Si) and 10 mM KNO3 (N)—prime signals for plant resistance to pathogens—were analyzed in healthy and Cowpea chlorotic mottle virus (CCMV) or Cowpea mild mottle virus (CMMV)-infected Bradyrhizobium-nodulated cowpea, yardlong ...

The metabolic fate of doubly labelled lactose-[13C, 15N]ureide after pre-dosing with different ureides [PDF]

European Journal of Clinical Nutrition, 2010
To date, the measurement of the orocaecal transit time (OCTT) with lactose-[(13)C]ureide usually requires a pre-dosing with the analogous substrate in its unlabelled form.In this study, the enzyme induction provoked by different unlabelled sugar ureides in OCTT measurements when using doubly labelled lactose-[(13)C, (15)N]ureide (DLLU) was evaluated ...

Allantoin accumulation in response to increased growth irradiance in Arabidopsis thaliana

Biologia Plantarum, 2018
Excess radiation is one of frequent natural environmental stresses that plants have to cope with on a daily basis. Therefore, plants have evolved many short- and long-term mechanisms to acclimate to high irradiance and tolerate it.

Absorption and Transport of Phosphorus in Nodulated Soybean Plants and Diagnosis of Phosphorus Status Using Xylem Sap Analysis

Agriculture
Phosphorus (P) is an essential major element for plants. The absorption and transport of P are important for soybean growth and yield, including nodule growth and N2 fixation. Through an analysis of xylem sap, we investigated how nodulated soybean plants

Disruption of ureide degradation affects plant growth and development during and after transition from vegetative to reproductive stages

BMC Plant Biology, 2018
Background The ureides allantoin and allantoate are major metabolic intermediates of purine catabolism with high nitrogen-to-carbon ratios. Ureides play a key role in nitrogen utilization in ureide-type legumes, but their effects on growth and ...
