A substance found in a native British flower has been turned into a powerful "smart bomb" drug that can work against a range of cancers.
The drug, based on colchicine found in the autumn crocus, cuts off the blood supply to solid tumours, curbing their growth and stopping cancer cells from spreading to other parts of the body.
Tests on laboratory mice have shown that the drug is highly effective at attacking tumours from a range of human diseases such as sarcomas and cancers of the breast, colon, lung and prostate. The drug is also designed to target solid tumours directly, leaving healthy tissue unaffected, according to Professor Laurance Patterson, director of Bradford University's Institute for Cancer Therapeutics.
"What we've designed is, effectively, a 'smart bomb' that can be targeted directly at any solid tumour to kill it without appearing to harm healthy tissue," Professor Patterson said.
"What is also new about our approach is that we are effectively targeting the blood supply of the tumour," he said. "If you can starve the tumour of that blood supply, then you can shut off its ability to grow and, indeed, you also shut off its ability to move around the body."
