Irradiation of a toluene solution containing cyclopentadienone tricarbonyl iron complexes and isocyanides with blue LEDs afforded the formation isolation 12 triisocyanide complexes, two which, namely tris(2,6-dimethylphenyl isocyanide)(η 4 -tetraphenylcyclopenatedienone)iron, [Fe(C 9 H N) 3 (C 29 20 O)], tris(naphthalen-2-yl -tetraphenylcyclopenatedienone)iron acetone hemisolvate, 11 7 O)] 2 ·C...

A new route to luminescent derivatives of androgenic steroids containing a ketone group in the 3- or 17-position has been developed. Reaction with the fac-Re(CO)(3)Cl complex of 3,3'-diamino-2,2'-bipyridine (complex 1) afforded a cyclic aminal product with different steroids. The rate of reaction and yield varies according to the conjugation or steric hindrance around the ketone group.

In this review ligand exchange and complex formation reactions on fac-[(CO)3M(H2O)3] (M = Mn, Tc, Re) and on fac-[(CO)2(NO)Re(H2O)3] are presented. A variety of experimental NMR techniques are described and it is shown that sometimes combinations of techniques applied at variable temperature or variable pressure allowed to measure exchange rate constants and their activation parameters as well ...

Since its outbreak, the severe acute respiratory syndrome—coronavirus 2 (SARS-CoV-2) has impacted quality of life and cost hundreds-of-thousands lives worldwide. Based on global spread mortality, there is an urgent need for novel treatments which can combat this disease. To date, 3-chymotrypsin-like protease (3CLpro), also known as main protease, considered among most important pharmacological ...

In recent years, the diagnostic and therapeutic uses of radioisotopes have shown significant progress. Immunoglobulin (Ig) appears to be a promising tracer, particularly due to its ability to target selected antigens. The main objective of this study is to optimize and assess an Ig radiolabeling method with Technetium 99m (99mTc), an attractive radioelement used widely for diagnostic imaging. M...
