Definitions
- the present invention relates to compounds for use in the treatment or prevention of pain in the mammal, especially in humans, and a process for the preparation thereof.
- Analgesics used today are older products and many of them date from the I 9th century. Morphine remains the standard analgesic for pain known as excess nociception.
- morphine can cause multiple side effects such as drowsiness, respiratory depression, nausea, vomiting, convulsions, miosis, constipation or dry mouth.
- Cinnamyl 3,4-dihydroxy- ⁇ -cyanocinnamate or CDC has been described as activator of TREK-1 channels (Sanjay et al., Mol Pharmacol. , 2004, 65, 599-610). However, this document does not describe any analgesic activity of the CDC.
- a first object of the invention is to provide pain-relieving compounds which overcome the drawbacks of the state of the art and which provide a solution to all or part of the problems of the state of the art.
- Another objective is to provide pain-relieving compounds whose efficacy for the treatment of pain, especially so-called excess nociceptive pain, is equivalent to or even greater than that of the compounds currently available, in particular morphine, while removing or limiting the risk of adverse effects.
- Another object of the invention is to provide pain-relieving agents that can be combined with other pain-relieving agents, such as morphine, thus reducing the risk of side effects related to their use.

- Acute pain is the pain that triggers reactions whose purpose is to reduce the cause and limit the consequences. Acute pains are mainly short pains and last only a few seconds. It may include, for example, pain following contact with the skin with fire or following an insect bite.
- Pains by excess of nociceptive stimuli are those originating from the stimulation of nociceptors by substances released by damaged or inflamed tissues, these substances including in particular extracellular protons, nucleotides, nerve growth factors, serotonin or the bradykinin. They result mainly from lesions of the peripheral tissues, thus causing an excess of painful impulses transmitted by the nervous system.
- Chronic pain is pain that can last for months or even years. They can be accompanied by inflammatory or neuropathic pathologies.
- Neuropathic pain is pain associated with peripheral or central lesions. These pains are related to a dysfunction of the mechanisms of control of the nociceptive messages and can be classified according to 2 types: peripheral neuropathic pain that may be caused by a medicinal treatment, for example by the alkaloids of the periwinkle (vinorelbine) used in the treatment of cancers,
- visceral pain is meant the pain being essentially of a hypernociceptive nature, which can originate in the cutaneous zone. They can be accompanied by hyperalgesia of the skin and deep tissue, tonic muscle contractions and intense emotional responses.
- Cancer pain is understood to mean pain that develops in a cancerous context, associating both an excess of cancer-related nociception and a neuropathic component, related to a dysfunction of the peripheral nervous system following the invasion of the lesions or the treatments. .
- Pains by dysfunction of the sympathetic system means the pains expressing both in the form of an excess of nociception, signs suggestive of a neuropathic component but also of sympathetic disturbances.
- Psychic pain is understood to mean pain accompanying mental pathologies, for example depression or schizophrenia.

- Level 2 analgesics are weak central analgesics for moderate to severe pain, which may be combinations of level 1 analgesics and weak opioid analgesics, such as tradamol.
- Level 3 analgesics are strong central pain relievers for very severe and uncomfortable pain, such as strong opioids (morphine, pethidine, dextromoramide) and antagonists (pentazocine, nalbuphine).
- the compositions may be administered simultaneously, simultaneously or extemporaneously to the patient.
