Induction of autophagic death in cancer cells is one of the promising strategies for the development of anti-cancer therapeutics. In the present study, we designed and synthesized a series of isatin Schiff base derivatives containing thioether structures. After discovering the highly active target compound H13 (IC = 4.83 μM) based on in vitro antiproliferation, we also found it had a high safety against normal cells HEK293 with CC of 69.01 μM, indicating a sufficient therapeutic window. In addition, to provide reference for subsequent studies, a model was successfully constructed by Sybyl software. Preliminary mechanistic studies suggested that H13-induced apoptosis may be closely related to ROS accumulation and mitochondrial dysfunction. Subsequent studies revealed that H13 inhibited cell proliferation by inducing cellular autophagy mainly through blocking signal of the PI3K/AKT/mTOR pathway. Altogether, these results suggested that H13 was potentially valuable as a lead compound.

The ability to induce nonapoptotic cell death is critical to fight apoptosis-resistant cancers. Excessive reactive oxygen species (ROS) can promote nonapoptotic cell death. We report six potent cyclometalated iridium(III) complexes derived from isatin-hydrazone Schiff bases with nanomolar IC values against pancreatic (MIA-PaCa-2, PANC-1) and breast (MDA-MB-231, MCF-7) cancer cells.

To advance the industrialization of the chemical productions, i.e., the organo-oxidizing reactions, a mono-organometallic Cu(II) diisatin-Schiff base complex (Cu(HmeL)Cl) is constructed from the complexing action of isatin-Schiff base ligand (HmeL) with half the amount of copper(II) chloride.

Epilepsy continues to be a challenging neurological disorder with a partially understood etiology that necessitates novel therapeutic strategies. This study introduces isatin-functionalized benzenesulfonamides (5a-f and 7a-e) targeting carbonic anhydrase (CA) isoforms II and VII implicated in seizure mechanisms. The design exploits a one-tail approach, integrating a sulfonamide warhead for zinc coordination in the CA active site, a triazole linker (inspired by FDA-approved antiepileptic rufinamide), and an isatin-based tail.

Aims: This study aimed to synthesize and characterize a Schiff base ligand, (Z)-2-(2-oxoindolin-3-ylidene)hydrazinecarbothioamide (1), and its copper(II) (2) and zinc(II) (3) complexes, as well as evaluate their binding interactions with the epidermal growth factor receptor (EGFR) and anticancer activity against the human lung cancer A549 cell line.
Materials & Methods: The Schiff base ligand was synthesized by refluxing isatin and thiosemicarbazide for 3 hours. Complexes 2 and 3 were formed and characterized using elemental analysis, molar conductivity, IR, NMR, and UV-Visible spectroscopy.

Pesticides are intensively employed to manage pests, but they pose a great challenge, developing pesticide resistance. So, searching for novel chemical structures is crucial to overcoming insecticide resistance. Herein, a new functionalized pyridine derivative 4 was effectively constructed in a one-step reaction through reacting four components, including piperonal, ethyl cyanoacetate, 2-acetylthiophene, and ammonium acetate, under ultrasonic conditions.
