Magnetic susceptibility measurements on single crystals of Mn(II)(trz)2(NCS)2 in the temperature range 1.8 - 300 K are reported. The compound has two-dimensional structural and magnetic properties. The data from susceptibility measurements are accounted for by considering the material to be a quadratic-layer, S = 5/2 Heisenberg antiferromagnet.

ABSTRACT Catharanthus roseus contains nearly 200 bioactive monoterpenoid indole alkaloids (MIAs) that are effective in treating cancer and other diseases. Ethylene plays a significant role in enhancing MIA biosynthesis, and we have found that it greatly induces the accumulation of anhydrovinblastine.

α-N-heterocyclic thiosemicarbazone derivatives as potential antitumor agents: A structure-activity relationships approach [PDF]
α-N-Heterocyclic thiosemicarbazones, (N)-TSCs, are potent inhibitors of ribonucleotide reductase (RR). This enzyme plays a critical role in DNA synthesis and repair, and is a well-recognized target for cancer chemotherapeutic agents.

ABSTRACT Low temperature triggers Ca2+ signalling and reprogramming of gene expression and metabolism in plants. However, how the Ca2+ signal is transduced to the downstream metabolic pathways remains unknown. The involvement of a cold‐induced calmodulin‐like protein, MfCML50, from Medicago falcata in regulation of cold tolerance was examined in the ...

ABSTRACT Phosphorus is indispensable in agricultural production. The growing global demand for food necessitates the development of crops with enhanced phosphorus utilisation efficiency. However, the molecular mechanisms coordinating phosphorus utilisation efficiency in plants remain incompletely characterised.
