“…Some differences were noted in other rigid analogs, although only changes in motor activity and LD50 data have been reported (3,4). In the cyclopropane series, the trans-isomer shows equivalent peripheral amphetamine-like effects, e.g., pressor response, moderate central nervous system stimulation, and increased monoamine oxidase inhibition when compared to amphetamine.…”

“…Papers by Bastian (1949 on), Cannon (1955), Gridgeman (1955), Hiskey et al (1949 on), Kortum (1937), Lothian (1956), Neal (1956, Reilley et al (1955 on), Ringbom et al(1939Ringbom et al( , 1953, all give useful practical and theoretical details and (many of them) bibliographies. There is, for instance, much to be said for and against reading in % T instead of absorbance, calibrating the responses and reading-off from the calibration curves instead of directly reading absorbance-differences.…”

“…Even with this calibration, precision is often poor. Kortum (6) and Bastían (1) described a differential method which partially corrects this difficulty by comparing unknowns to standards instead of the normal reagent blanks. However, this method is also limited by the effectiveness of the monochromator, slit width, Figure 2.…”
