The LD 50, resulting in the death of 50% of the animals, was evaluated and showed the low toxicity of the compounds of the invention.
  • the compounds of the invention are tested in a behavioral model, the forced swimming test.
  • the apparatus consists of a Plexiglas cylinder filled with water.
  • the animals are tested individually during a 6-minute session. At the beginning of each test, the animal is placed in the center of the cylinder. The downtime is recorded. Each animal is judged immobile when it ceases to struggle, and remains on the surface of the water, motionless, making only the movements allowing it to keep its head out of the water.
  • MT 1 or MT 2 receptor binding experiments were performed using 2- [ 125 I] -iodomelatonin as a reference radioligand. The retained radioactivity is determined using a liquid scintillation counter.

  • One-month-old male rats are subjected to a light cycle of 12 hours of light per day as soon as they arrive at the laboratory (LD 12:12). After 2 to 3 weeks of adaptation, they are placed in cages equipped with a wheel connected to a recording system in order to detect the phases of locomotor activity and thus to follow the diurnal (LD) or circadian (DD) rhythms. ).
  • the rats receive a daily administration of the molecule to be tested.
  • the compounds of the invention are tested in a behavioral model, the light / dark cages test, which reveals the anxiolytic activity of the molecules.
  • the device consists of two polyvinyl boxes covered with Plexiglas. One of these boxes is obscure. One lamp is placed above the other box giving a luminous intensity in the center of it of approximately 4000 lux. An opaque plastic tunnel separates the clear box from the dark box. The animals are tested individually during a 5 min session. The floor of each box is cleaned between each session. At the beginning of each test, the mouse is placed in the tunnel, facing the dark box. The time spent by the mouse in the lighted box and the number of transitions through the tunnel are recorded after the first entry in the dark box. After administration of the compounds 30 min before the start of the test, the compounds of the invention significantly increase the time spent in the illuminated cage and the number of transitions, which shows the anxiolytic activity of the derivatives of the invention.
