TRIP-1a

Development stage: Preclinical
Modality: Covalent Small Molecules → Small Molecules, DNA Intercalators/Alkylators → Nucleic Acid-Directed Small Molecules → Small Molecules, Light/Condition-Responsive Prodrugs → Prodrugs/Conditional Activator Small Molecules → Small Molecules

Overview

TRIP-1a is a rhenium(I) tricarbonyl isonitrile polypyridyl complex, specifically fac-[Re(CO)3(dmphen)(ptolICN)]+. It is being explored as an anticancer agent to overcome limitations of platinum-based drugs, such as toxic side-effects and cancer-resistance mechanisms. Its mechanism of action involves inducing endoplasmic reticulum (ER) stress and activating the unfolded protein response (UPR) pathway. Preclinical studies in NSG mice bearing A2780 ovarian cancer xenografts demonstrated that TRIP-1a inhibited tumor growth and prolonged mouse survival by 150% compared to vehicle control. A 99mTc congener of TRIP-1a was also synthesized, showing similar biodistribution patterns to the parent complex, suggesting its potential as a diagnostic partner agent.
