生物活性
Azaguanine-8 is a purine analogs showing antineoplastic activity by competing with guanine in the metabolism. 8-Azaguanine is a purine analogue that shows antineoplastic activity.Azaguanine-8functions as an antimetabolite and easily incorporates into ribonucleic acids, interfering with normal biosynthetic pathways, so that it can inhibite cellular growth.Azaguanine-8has been reported that a study of the in vivo metabolism of 8-azaguanine-2-C 14 by mouse neoplasms that are susceptible or resistant to growth inhibition by 8-azagnanine. The results show that the growth of those neoplasms which convert significant amounts of 8-azaguanine to 8-azaguanylic acid is inhibited by 8-azaguanine.

例如,依据体表面积折算法,将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量,需要将20 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到化合物用于大鼠的等效剂量为10 mg/kg。
