CATCH ME UP

Indian scientists have successfully developed a new targeted cancer treatment known as RK-251.

The drug was created through a collaboration between researchers at IASST and IIT-Guwahati.

It functions by exploiting elevated levels of reactive oxygen species inside cancer cells.

This mechanism allows the drug to activate primarily within tumours while sparing healthy tissue.

More context

Preclinical tests demonstrated strong efficacy against aggressive triple-negative breast cancer cells.

Additionally, initial evaluations in zebrafish embryos showed encouragingly low toxicity levels.

Researchers emphasize that the treatment remains strictly in the preclinical research stage.

Further rigorous testing and development are required before human clinical trials can begin.

Indian scientists develop 'smart' cancer drug that targets tumour cells while sparing healthy cells

Quick source take

Researchers in India have developed a new smart cancer drug named RK-251, designed to activate primarily inside tumour cells while sparing healthy tissue. Developed collaboratively by scientists from IASST and IIT-Guwahati, the drug exploits elevated levels of reactive oxygen species found in cancer cells to release an anticancer compound. Preclinical tests showed strong activity against triple-negative breast cancer cells and low toxicity in zebrafish embryos. The authors report that the drug remains in preclinical stages and requires further study before human clinical trials.
