Downregulation of miR-221-3p promotes the ferroptosis in gastric cancer cells via upregulation of ATF3 to mediate the transcription inhibition of GPX4 and HRD1.

Background: Gastric cancer (GC) is an aggressive gastrointestinal tumor. MiRNAs participate in the tumorigenesis of GC. Nevertheless, the function of miR-221-3p in GC remains largely unknown.

In the title hydroxamic acid derivate, C22H16Cl2N2O5, the nitro-substituted benzene ring forms dihedral angles of 14.11 (15) and 16.08 (15)°, with the 4-chloro-benzoyl and 4-chloro-phenyl benzene rings, respectively.
