Cyprazepam[1] is a drug which is a sedative-hypnotic benzodiazepine derivative.[2][3][4][5] It has anxiolytic properties,[6] and presumably also has hypnotic, skeletal muscle relaxant, anticonvulsant and amnestic properties.

Synthesis[edit]

The lactam moiety in benzodiazepams is active towards nucleophiles and numerous analogues have been made by exploiting this fact.

Cyprazepam synthesis:[1]

For example, heating demoxepam with N-cyclopropylmethylamine leads to amidine formation, the minor tranquilizer cyprazepam.

One thought on “Cannabaceae”

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
