Sulfasalazine / ChemoSen Cancer Research Results

SAS, Sulfasalazine: Click to Expand ⟱
Features:
Sulfasalazine is primarily known as an anti-inflammatory and disease‐modifying antirheumatic drug (DMARD), used for conditions such as rheumatoid arthritis and inflammatory bowel diseases (e.g., ulcerative colitis).

-Inhibit the nuclear factor kappa B (NF-κB) pathway.
-Sulfasalazine has been noted to interfere with the cystine/glutamate antiporter (system x_c⁻), which can reduce glutathione levels in cancer cells, potentially making them more susceptible to oxidative stress.

-Ability to inhibit anti-oxidant production (for ProOxidant effect).

Rank Pathway / Target Axis Direction Primary Effect Notes / Cancer Relevance Ref
1 System xC− (xCT/SLC7A11 cystine–glutamate antiporter) ↓ cystine uptake Limits cystine supply Sulfasalazine is used as an xCT inhibitor; blocking cystine uptake is the core upstream action in cancer models (ref)
2 Glutathione biosynthesis / GSH pool ↓ GSH Loss of redox buffering In glioma cells, cystine uptake blockade by sulfasalazine leads to glutathione depletion (ref)
3 ROS accumulation ↑ ROS Oxidative stress amplification Glioma study: sulfasalazine increases ROS after GSH depletion (mechanistic sequence shown) (ref)
4 DNA damage (oxidative/genotoxic stress) ↑ DNA damage Checkpoint/death signaling Glioma study: sulfasalazine causes DNA damage as part of the ROS-driven cytotoxic cascade (ref)
5 Radiosensitization (oxidative vulnerability) ↑ radiation sensitivity Enhances radiotherapy effect Melanoma model: sulfasalazine decreases glutathione and synergistically enhances X-irradiation cytotoxicity (ref)
6 Ferroptosis (system xC− → GSH/GPX4 vulnerability) ↑ ferroptotic death Iron-dependent oxidative death Paclitaxel-resistant uterine serous carcinoma model: sulfasalazine (xCT inhibitor) induces ferroptotic cell death signatures (ref)
7 Mitochondrial apoptosis (caspase pathway) ↑ apoptosis Programmed cell death Osteosarcoma work: sulfasalazine blocks system xC− and induces cell death consistent with ferroptosis/apoptosis programs (apoptosis markers reported in the paper’s mechanism set) (ref)
8 NF-κB activation (IκBα degradation / IKK activity) ↓ NF-κB activation Reduced pro-survival/inflammatory transcription Mechanistic paper shows sulfasalazine blocks NF-κB activation by inhibiting IκBα degradation via IKK inhibition (ref)
9 NF-κB nuclear translocation ↓ nuclear NF-κB Transcriptional shutdown Colon cancer cells: sulfasalazine prevents TNFα-induced NF-κB nuclear translocation and NF-κB–dependent transcription (ref)
10 Chemo-sensitization via xCT inhibition ↑ chemo sensitivity (context-dependent) Combination benefit Mechanistic rationale: xCT inhibition lowers GSH and oxidative defense, increasing sensitivity to cytotoxic stress (glioma + radiation shown explicitly) (ref)
11 Tumor growth suppression in vivo (xCT-targeted stress) ↓ tumor growth Anti-tumor efficacy Glioma xenograft model: sulfasalazine plus radiosurgery improves survival compared to control/monotherapy (ref)
12 Resistance axis: xCT-high / antioxidant-high tumors ↑ vulnerability when xCT-high Targeted susceptibility Endometrial/USC model: sulfasalazine shows stronger cytotoxicity in resistant (stress-adapted) cells consistent with xCT dependence (ref)
