Cancer treatment breakthrough: 'smart' drug promises to spare healthy cells

Scientists from the Institute of Advanced Study in Science and Technology (IASST) and the Indian Institute of Technology-Guwahati have developed a new 'smart' cancer drug called RK-251. RK-251 is designed to activate primarily in cancer cells and release a powerful anticancer compound, and has shown strong activity against aggressive triple-negative breast cancer cells in preclinical studies.

Quick Revision

Prelims-testable facts

01A new 'smart' cancer drug called RK-251 has been developed by scientists at the Institute of Advanced Study in Science and Technology (IASST) and the Indian Institute of Technology-Guwahati.
02RK-251 is designed to activate primarily in cancer cells and does not harm healthy cells.
03The drug works by releasing a powerful anticancer compound called 'NBDHEX' when it detects high levels of reactive oxygen species (ROS) in cancer cells.
04NBDHEX blocks target proteins that many cancer cells use to survive and resist treatment.
05Preclinical studies have shown that RK-251 has strong activity against aggressive triple-negative breast cancer cells.
06The drug has much less effect on healthy cells compared to traditional chemotherapy.
07The activation of RK-251 is triggered by the high ROS levels produced by cancer cells.

Trap alerts

Most people think that all 'smart' cancer drugs work by targeting specific genetic mutations in cancer cells, but actually, RK-251 works by detecting high levels of ROS.
Most people think that RK-251 is the first 'smart' cancer drug to be developed, but actually, it is part of a larger body of research in this area.

Current-affairs link

The Indian government has launched several initiatives to promote research and development in the field of cancer treatment, including the 'National Cancer Mission' which aims to provide affordable cancer treatment to all citizens.

Prelims Practice MCQs

Single facteasy

RK-251 is a 'smart' cancer drug that activates primarily in which type of cells?

A.cancer cells
B.healthy cells
C.stem cells
D.immunocytes

RK-251 is a cancer drug that targets and activates in cancer cells, sparing healthy cells. This targeted approach is a significant advancement in cancer treatment.

Multiple statementsmedium

Consider the following statements regarding RK-251 Cancer Drug: 1. RK-251 is a smart cancer drug developed by the Department of Science & Technology (Govt. of India). 2. RK-251 is designed to activate in cancer cells by targeting high levels of reactive oxygen species (ROS). 3. RK-251 has been approved for human clinical trials by the Indian Council of Medical Research. How many of the above statements are correct?

A.Only one
B.Only two
C.All three
D.None

The first statement is correct because the Department of Science & Technology (Govt. of India) has an Autonomous Institute called the Institute of Advanced Study in Science and Technology (IASST), and RK-251 is mentioned as a new 'smart' cancer drug developed. The second statement is correct because when RK-251 enters a cancer cell, the high ROS levels trigger the drug's activation. The third statement is false because there is no mention of RK-251 being approved for human clinical trials by the Indian Council of Medical Research.
