補充產品訊息:
Previously this product had been labeled as a hydrate form both in product name and molecular formula. The hydrate form had no exclusive CAS RN and used to share the same CAS RN as the anhydrous form.
To avoid any misleading information and since moisture in product is considered as an impurity, we have decided to remove the term 'Hydrate' from product name and 'xH2O' from the molecular formula for such products.
Please use it at ease since there is no difference in product quality, even if you see the previous indications on a part of label.

Application
Strychnine: An Indole Alkaloid with Antagonistic Activity toward Glycine and Acetylcholine Receptors
Strychnine [S0249] is an indole alkaloid obtained from the seeds and bark of Strychnos nux-vomica, has been used as a rodenticide for more than a century. Glycine is an inhibitory transmitter to motor neurons and interneurons in the spinal cord. Strychnine is a neurotoxin which acts as an antagonist of glycine and acetylcholine receptors, resulting in disinhibition of motor neurons in the spinal cord.1,2) In addition, strychnine has been a target compound for total synthesis since it was first synthesized by the group of R. B. Woodward in 1954.3,4) Strychnine is poorly soluble in water, but its sulfate [S0094], nitrate [S0093] and hydrochloride [S0257] are moderately soluble in water. (The product is for research purpose only.)
