Schiff Base Compound of (E)‐1‐(((4‐chloro‐2‐hydroxyphenyl)imino)methyl)naphthalen‐2‐ol as CDK2 Inhibitory Agent: Structural Characterization, Density Functional Theory Computational, and In Silico studies

Chemistry &Biodiversity, EarlyView.
ABSTRACT Compound (E)‐1‐(((4‐chloro‐2‐hydroxyphenyl)imino)methyl)naphthalen‐2‐ol (HNC) was prepared by the reaction between 2‐hydroxynaphthyl‐1‐carboxaldehyde and 2‐amino‐5‐chlorophenol in an equimolar ratio and obtained in moderate yield. HNC was characterized using physicochemical and various spectroscopic techniques.

Total Synthesis and Complete Stereochemical Assignment of Amphirionin‐5, a Potent Natural Osteoblasts Proliferator

ChemistryEurope, EarlyView.
The convergent total synthesis of a candidate diastereomer of amphirionin‐5 was accomplished in 22 steps via the coupling of the C1‐C16 enone segment and the C17‐C28 aldehyde segment using Stetter reaction. The overall stereochemistry of amphirionin‐5 was fully assigned, based on the comparison of spectroscopic and chiroptical data between the ...

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

ChemMedChem, 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 ...
