Colchicine,
a medicine derived from the dried seeds of the crocus that has
long been used to prevent or relieve gout attacks, may also be
useful in fighting colorectal cancer, according to Uzbek researchers.
Zulfiya Enikeeva,
a researcher at the Uzbek Health Ministry's oncology research
center, reported that more than 1,000 mice inoculated with colorectal
cancer cells were subsequently treated the mice with a lower-toxicity
colchicine derivative called K48.
The treatments
lasted eight to 10 days, with one injection or oral dose per day.
Ten days after the treatments, Enikeeva reported about 60 percent
of the treated rodents showed no signs of tumors.
Enikeeva said
K48 potentially could be taken by patients who undergo chemotherapy
or radiation therapy because the drug appears to stimulate the
immune system rather than weakening it.
"The
toxicity of K48 is 360 times lower than the toxicity of colchicine,"
Enikeeva told United Press International.
"The
medication is potentially promising," added Zainab Khushbaktova
of the pharmacology department of Uzbekistan's Research Institute
of Vegetable Substances Chemistry.
