Novel Quinoline Nitrate Derivatives: Synthesis, Characterization, and Evaluation of their Anticancer Activity with a Focus on Molecular Docking and NO Release.

Background: Nitric Oxide (NO) has recently gained recognition as a promising approach in the field of cancer therapy. The quinoline scaffold is pivotal in cancer drug research and is known for its versatility and diverse mechanisms of action.

Objective: This study presents the synthesis, characterization, and evaluation of novel quinoline nitrate derivatives as potential anticancer agents.

Functional implications and therapeutic targeting of androgen response elements in prostate cancer.

The androgen receptor (AR) plays an essential role in the growth and progression of prostate cancer (CaP). Ligand-activated AR inside the nucleus binds to the androgen response element (ARE) of the target genes in dimeric form and recruits transcriptional machinery to facilitate gene transcription. Pharmacological compounds that inhibit the AR action either bind to the ligand binding domain (LBD) or interfere with the interactions of AR with other co-regulatory proteins, slowing the progression of the disease.

Late-Stage Modification of Oligopeptides by Nickel-Catalyzed Stereoselective Radical Addition to Dehydroalanine.

Radical addition to dehydroalanine (Dha) represents an appealing, modular strategy to access non-canonical peptide analogues for drug discovery. Prior studies on radical addition to the Dha residue of peptides and proteins have demonstrated outstanding functional group compatibility, but the lack of stereoselectivity has limited the synthetic utility of this approach. Herein, we address this challenge by employing chiral nickel catalysts to control the stereoselectivity of radical addition to Dha on oligopeptides.
