Baseline multi-omics signatures could predict therapeutic response to neoadjuvant anti-PD-1 immunochemotherapy in non-small-cell lung cancer. [PDF]

open access: yesClin Transl Med
Overview of study design. Metagenomic and plasma/fecal metabolomic studies were performed in 44 NSCLC patients who underwent neoadjuvant tislelizumab therapy plus platinum ‐ based doublet chemotherapy. Abstract Background Neoadjuvant anti‐programmed cell death 1 (PD‐1) immunochemotherapy has shown promising efficiency in the treatment of early‐stage ...

Combination of an Oxindole Derivative with (−)-β-Elemene Alters Cell Death Pathways in FLT3/ITD+ Acute Myeloid Leukemia Cells

open access: yesMolecules, 2023
Acute myeloid leukemia (AML) is one of the cancers that grow most aggressively. The challenges in AML management are huge, despite many treatment options. Mutations in FLT3 tyrosine kinase receptors make the currently available therapies less responsive.

Oxindoles and copper complexes with oxindole-derivatives as potential pharmacological agents [PDF]

open access: yesJournal of the Brazilian Chemical Society, 2006
Oxindoles are endogenous compounds found in mammalian body fluids and tissues. Particularly, isatin (1H-indole-2,3-dione) and its derivatives have shown a variety of biological effects, including inhibition of monoamine oxidase, antibacterial, antifungal, antiviral and antiproliferative activities.
