Direct and Indirect Inhibition Effects of Resveratrol against Tachyzoites .

is one of the most widespread obligatory parasitic protozoa and infects nearly all warm-blooded animals, leading to toxoplasmosis. The therapeutic drugs currently administered, like the combination of pyrimethamine and sulfadiazine, show high rates of toxic side effects, and drug resistance is encountered in some cases. Resveratrol is a natural plant extract with multiple functions, such as antibacterial, anticancer, and antiparasite activities.

Light-Induced Bidirectional Metal-to-Metal Charge Transfer in a Linear Fe Co Complex.

It is a challenge to reversibly switch both magnetism and polarity using light irradiation. Herein we report a linear Fe Co complex, whereby interconversion between Fe (μ-CN)Co (μ-NC)Fe (LS=low-spin, HS=high-spin) and Fe (μ-CN)Co (μ-NC)Fe linkages could be achieved upon heating and cooling, or alternating laser irradiation at 808 and 532 nm. The electron spin arrangement and charge distribution were simultaneously tuned accompanying bidirectional metal-to-metal charge transfer, providing switchable polarity and magnetism in the complex.
