Colchicine used as Antitumor drugs 64-86-8
Colchicine Active Pharmaceutical Ingredients(API) cas 64-86-8 is also known as colchicine, which is a kind of alkaloid extracted from the bulbs of Liliaceae, and the seeds are naturally present in the Liliaceae and Calamagrostis angustifolia, 0.11% and 0.1% The Pale yellow needle crystal. Slightly stinky and bitter. Melting point of 157 ° C, soluble in cold water, alcohol, chloroform and formaldehyde, poor solubility in hot water, insoluble in benzene and ether, almost insoluble in petroleum ether, 0.5% solution pH of 5.9, Toxicity is reduced. Colchicine Active Pharmaceutical Ingredients(API) cas 64-86-8 inhibits cell mitosis and anti-tumor effects. In 1889 the Italian scholar Perniche first discovered the effect of colchicine on mitosis, he described the division of the gastrointestinal wall of the dog’s stomach was inhibited by colchicine, the spindle was destroyed, the chromosomal action was paralyzed, and normal Mitotic cells remain in the middle.
This is caused by colchicine is not normal split called colchicine mitosis (referred to as C mitosis). In colony analysis and polyploid mutagenesis, Colchicine Active Pharmaceutical Ingredients(API) cas 64-86-8 is one of the most widely used chemical agents. The concentration of its aqueous solution and its role in a positive correlation, the higher the concentration, the stronger the role. Various plants and different tissues have different responses to colchicine. To sum up, the young and splitting tissue (such as germination of the seeds of germ) treatment time can be shorter, the concentration should be lower; the other side of the treatment time can be longer, the concentration should be higher.
The effective concentration of Colchicine Active Pharmaceutical Ingredients(API) cas 64-86-8 treatment is 0.01 ~ 0.4%, and the application range is about 0.2%. Such as the concentration of 0.2 ~ 0.4% of the Colchicine Active Pharmaceutical Ingredients(API) cas 64-86-8 solution drops in the diploid watermelon seedling growth point, once a day for 4 days, and shade to maintain humidity, Active Pharmaceutical Ingredients(API) can induce tetraploid watermelon. For cereal crops, such as rice, you can have more than four true leaves of the robust seedlings in the root neck cut a mouth, not to cut the growth point for the degree, immersed in 0.025 ~ 0.05% of colchicines solution, submerged incision , From 8 to 14 days (20 ℃) can also be tetraploid plants. At present, Colchicine Active Pharmaceutical Ingredients(API) cas 64-86-8 is widely used in anthers (powders), and the chromosomes of the resulting haploid plants are doubled in ovary.
