| Transient Receptor Potential Ankyrin 1, a Ca²⁺-permeable, nonselective cation channel. It is best known as a sensory “irritant/pain” receptor activated by electrophilic/pungent compounds such as allyl isothiocyanate, allicin, cinnamaldehyde, eugenol, and some cannabinoids.
TRPA1 is biphasic/context-dependent in cancer.
| Strategy |
Possible Effect |
Concern |
| TRPA1 inhibition |
May reduce oxidative-stress tolerance and improve chemosensitivity. |
Most compelling for breast/lung spheroid-type ROS-defense model. |
| TRPA1 activation |
In some models, strong activation causes Ca2+ overload, mitochondrial dysfunction, and apoptosis. |
Could also promote survival if activation is moderate or coupled to Ca2+ extrusion mechanisms. |
| Natural TRPA1 agonists |
Could be anticancer in some contexts. |
Could theoretically support survival in TRPA1-dependent cancers if dose/exposure creates adaptive Ca2+ signaling rather than overload. |

TRPA1 Relationship |
Database Note |
| Allicin / Garlic |
TRPA1 agonist(activated) |
Strong overlap; garlic organosulfur compounds are classic TRPA1 activators. |
| Allyl isothiocyanate / Mustard / Wasabi / Crucifers |
Strong TRPA1 agonist |
Relevant if sulforaphane or crucifer compounds are tracked separately. |
| Cinnamaldehyde / Cinnamon |
TRPA1 agonist |
Good tag under cinnamon or cinnamaldehyde. |
| Eugenol / Clove |
TRPA1 agonist/modulator |
Good tag under eugenol. |
| Gingerol / Ginger |
TRPA1 agonist |
Relevant if ginger or gingerol is in the database. |
| Cannabidiol / Cannabinoids |
TRPA1 agonist/modulator |
Mechanistically relevant, but pharmacology is broad. |
| Oleocanthal / Olive oil phenolics |
TRPA1 activation linked to pungency |
Lower cancer-specific relevance than allicin, allyl isothiocyanate, or cinnamaldehyde. |
