The primary purpose of the passage is to______ [br] In response to experimental results concerning IBMX, Snyder et al contended that it is not uncommon for psychoactive drugs to have______
选项
A、mixed effects in the brain
B、inhibitory effects on enzymes in the brain
C、close structural relationships with caffeine
D、depressive effects on mouse locomotion
E、the ability to dislodge caffeine from receptors in the brain
答案
A
解析
A is the best answer. The effects of IBMX are discussed in the last paragraph of the passage. IBMX apparently binds to adenosine-specific receptors on neuronal membranes, but, in contrast to the other caffeine derivatives that Snyder et al experimented with, IBMX depresses rather than stimulates mouse locomotion. Snyder et al respond to this experimental result by stating that IBMX has “mixed effects in the brain, a not unusual occurrence with psychoactive drugs”(line 104-107)
