Novel heterocycle-fused thyromimetics are presented carrying indoles or indazoles instead of the phenolic group in T3. Potent agonists were identified in both series. SAR trends are examined and found to be mostly consistent with previously published thyromimetics. Moderate THRbeta selectivity (approx. 10-fold) was observed in the indole series using isoform-selective transient THR transfection assays.

Two novel 3D inorganic-organic hybrids based on [VO]/[VO] clusters, [Cu(bbpy)(VO)]·3HO () and [CuAg(pty)(VO)]·HO () (bbpy = 3,5-bis(1-benzimidazole) pyridine, pty = 4'-(4″-pyridyl)-2,2':6',2″-terpyridine), were isolated in the same POV/Cu/N-heterocycle ligand reaction systems. Hybrids and possess novel three-dimensional bimetallic frameworks derived from [VO]/[VO] clusters and Cu-organic complexes. In , bbpy ligands are grafted by Cu to a grid ribbon 2D sheet, which are connected with benzene-like [VO] to yield a 3D framework.

Globally, an estimated 1 billion people reside in endemic areas, and over 12 million individuals are infected with leishmaniasis. Despite its prevalence, leishmaniasis continues to be a neglected disease, mainly affecting underdeveloped countries. In Brazil, the available treatments are pentavalent antimonials and Amphotericin B, which are outdated, toxic, require prolonged parenteral administration and have limited efficacy.

In the last few years, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been the cause of a worldwide pandemic, highlighting the need for novel antiviral agents. The main protease (M) of SARS-CoV-2 was immediately identified as a crucial enzyme for viral replication and has been validated as a drug target. Here, we present the design and synthesis of peptidomimetic M covalent inhibitors characterized by quinoline-based P moieties.
