From Wikipedia, the free encyclopedia
Cypenamine, or
phenylcyclopentamine, is a stimulant drug. It is currently known only in scientific research and has never been developed for
market use. The trans- isomer is reported to be more active than the racemate.[1]
Cypenamine is currently legal throughout the entire world, and though its chemical
structure has a vague similarity to certain controlled stimulants like fencamfamine
(Glucoenergan, Reactivan), it is likely that it is too distant for
it to be considered an illicit analogue under say the United States
(U.S.) Federal Analogue Act (FAA) of the Controlled Substances Act
(CSA).
Stereochemistry
2-Phenylcyclopentan-1-amine is a compound with two stereocenters. Thus,
the following four following stereoisomers may
exist:
-
(1R,2S)-trans-2-phenylcyclopentan-1-amine
-
(1S,2R)-trans-2-phenylcyclopentan-1-amine
-
(1R,2R)-cis-2-phenylcyclopentan-1-amine
-
(1S,2S)-cis-2-phenylcyclopentan-1-amine
The racemate
(±)-trans-2-phenylcyclopentan-1-amine [1:1 mixture of
(1R,2S)-trans-2-phenylcyclopentan-1-amine
(box, left) and
(1S,2R)-trans-2-phenylcyclopentan-1-amine
(box, right)] is the active ingredient of cypenamine.[2]
Furthermore, the kinetic resolution of
(±)-trans-2-phenylcyclopentan-1-amine by lipase B from
Candida antarctica may effectivily performed by an
aminolysis reaction.[2]
Racemic cis-2-phenylcyclopentan-1-amine [1:1 mixture of
(1R,2R)-cis-2-phenylcyclopentan-1-amine
and
(1S,2S)-cis-2-phenylcyclopentan-1-amine]
has found no pharmacological application.
Homology
Cypenamine is an obvious homologue, containing an expanded
alicyclic ring that is two -CH2- units larger than the highly
strained/reactive cyclopropane of tranylcypromine. Based on this
logic, one would have to contend that the cyclobutane homologue is
yet another possibility. The cyclohexane homologue is known to have
been reported, although the LD50's were all less than
for plain amphetamine, it was still a functional stimulant.
