Further literature review and feasibility assessment narrowed the list to six candidates: malonaldehyde, mercaptoethanol, glycine, para-chlorophenol, methoxyamine, and ethanolamine. These findings support YBX1 as a promising therapeutic target in hepatocellular carcinoma and demonstrate the utility of drug repurposing to rapidly identify candidate inhibitors. Targeting YBX1 may provide a viable strategy for enhancing treatment efficacy and overcoming sorafenib resistance in advanced HCC.
Herein, we developed MOSCAT (MethOxyamine-enabled Site-specific Cinnamaldehyde Tagging), a probe-free chemical proteomic strategy for mapping cinnamaldehyde-targeted proteins in living cells...This modification triggers proteasome-mediated GPX4 degradation, identifying a specific covalent engagement site associated with CA-induced ferroptosis. Our findings demonstrate MOSCAT as a powerful platform for elucidating molecular mechanisms of electrophilic natural products and highlight GPX4 Cys93 as a promising druggable site for CA-based therapeutic interventions.

Co-treatment with ATR inhibitor (VX970) and BER inhibitor (methoxyamine) at clinically relevant doses synergistically enhanced DNA damage and reduced cell proliferation in PDAC cells. The study provides mechanistic insights into the regulation of TRCs in PDAC by the BER pathway, which has biologic and therapeutic implications.
These findings confirm safety and feasibility of TRC102+TMZ for rGBM patients. They also warrant further evaluation of combination therapy in biomarker-enriched trials enrolling GBM patients with baseline hyperactivated DDR pathways.
TRC102 (methoxyamine), a small molecule DNA base-excision repair (BER) inhibitor, reverses temozolomide (TMZ) resistance in preclinical glioma models...If sufficient activity was identified, arm 2 was planned in bevacizumab-refractory patients... rGBM patients with elevated levels of MPG and DDR molecular signature may have impaired BER and respond better to TRC102+TMZ.
