This communication presents the first Gd(iii)-based T1 MRI contrast agent, o-MeHgGad, for noninvasive visualization of CH3Hg+. o-MeHgGad showed a relaxivity enhancement of 62% in the presence of 1 equiv. of CH3Hg+. Moreover, a noticeable contrast enhancement was recorded in the liver, kidney, and intestine of mice exposed to CH3Hg+. Thus, the newly designed contrast agent has the potential to be used for in vivo bio-imaging of CH3Hg+ and could be useful for biomedical applications.

This paper reports on the selective conversion of alkyl azido groups at the carbonyl α-position to diazo compounds. Through β-elimination of dinitrogen, followed by hydrazone formation/decomposition, α-azidocarbonyl moieties were transformed into α-diazo carbonyl groups in one step. As these reaction conditions do not involve aryl or general alkyl azides, site-selective conversions of di- and triazides were achieved. Through this method, the successive site-selective conjugation of the triazido molecule with three different components is demonstrated.

A series of novel nitric oxide releasing derivatives of 6-amino-3-n-butylphthalide were designed, synthesized and evaluated as potential antiplatelet agents. Compound 10b significantly inhibited the adenosine diphosphate (ADP)-induced platelet aggregation
