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)

BMPs, Bone morphogenetic protein: Click to Expand ⟱

Type:

BMPs are important cytokines belonging to the Transforming Growth Factor (TGF)-β superfamily. BMP2 is highly overexpressed in human non-small cell lung cancer (NSCLC) and correlates with tumor stage and metastatic burden. BMP-2 level from patients with bone metastasis is significantly higher compared to patients without bone metastasis.
BMPs display significantly higher expression in tumors, which have been used as new biomarkers for the prognosis of cancer patients.
However, some data revealed an opposite role of BMP signaling in tumors. BMP-10 was downregulated in gastric cancer samples. BMP-6 expression was also absent in breast cancer tissues and might suppress breast cancer metastasis.
