Oxygenated Solanapyrone Analogs From Nigrospora sp. IQ‐064, a Mangrove Associated Fungus

open access: yesChemistry &Biodiversity, EarlyView.
ABSTRACT Two new oxygenated solanapyrone analogues, nigrosporapyrone E (1) and nigrosporapyrone F (2), were isolated from Nigrospora sp. strain IQ‐064, a fungus associated with the bark of black mangrove (Avicennia germinans L.), along with seven known compounds.

Reversible and Massive Structural Transformation in Meltable Cyanido‐bridged Coordination Polymer Crystals

open access: yesChemistry – A European Journal, EarlyView.
Melting crystals containing separated domains of KCd[Cu(CN)2]3 and K2Cu3(CN)5 were obtained via simple dehydration of K2Cd(H2O)Cu4(CN)8·1.5H2O. Their low melting point of 559 K resulted from the combined effects of strong crystal‐interface interactions and low‐coordinate Cu nodes.

Decoupling Redox Potentials and Excited State Energies in Substituted Chromium(III) Chromophores

open access: yesChemistry – A European Journal, EarlyView.
Redox and excited state properties of organic and precious metal CT photocatalysts are strongly entangled. In contrast, redox potentials of polypyridine chromium(III) complexes, that feature purely metal‐centered SF states, are selectively tuned by incremental substituent effects of the CF3 group, while excited state energies and lifetimes remain ...

Impact of C18 Epimerization of Indole‐ and Pyrazole‐Fused 18β‐Glycyrrhetinic Acid Derivatives on PTP1B and TCPTP Inhibitory Activity: Synthesis, In Vitro, and In Silico Studies

open access: yesChemMedChem, EarlyView.
The indole derivative (FC‐114) and the N‐phenylpyrazole (FC‐122) of glycyrrhetinic acid are both potent inhibitors of the Protein Tyrosine Phosphatase 1B, with IC50 values of 0.48 μM and 1.15 μM, respectively. However, their activity decreases by up to four times when the 18β‐H position is epimerized to 18α‐H or when the carbonyl group at the C11 ...
