Ivermectin was first approved for human use as an endectocide in the 1980s. It remains one of most important global health medicines history and has recently been shown to exert vitro activity against SARS-CoV-2. However, macrocyclic lactone family compounds not previously evaluated The present study aims at comparing their anti-viral relevant pulmonary cell lines vitro. Here, antiviral avermec...

In the title mol-ecule, C13H9NO, the fluorene system and the oxime group non-H atoms are essentially coplanar, with a maximum deviation from the fluorene mean plane of 0.079 (2) Å for the oxime O atom. A short intra-molecular C-H⋯O generates an S(6) ring. In the crystal, mol-ecules related by a twofold screw axis are connected by O-H⋯N hydrogen bonds, forming [100] chains Within these chains, m...

The configuration of the C=N double bond of the title compound, C(7)H(6)BrNO, is E; the non-H atoms are approximately coplanar (r.m.s. deviation = 0.038 Å). In the crystal, pairs of mol-ecules are linked by a pair of O-H⋯N hydrogen bonds about a center of inversion, generating hydrogen-bonded dimers.
