Definitions
- the present invention relates to Nav 1.7 and/or Nav 1.8 blocking hydroxamates, their processes for obtaining them, compositions containing them, uses, kits and treatment methods for treating or preventing pain-related pathologies.
- the present invention lies in the fields of medicinal chemistry, organic synthesis, as well as the treatment of pain-related diseases.
- Physiological pain is an important protective mechanism developed to alert the body to real or potential injuries that could put its integrity at risk.
- physiological pain can be classified into nociceptive pain and inflammatory pain.
- Nociceptive pain is characterized by having a high activation threshold, which remains until the stimulus that generated it is eliminated.
- Inflammatory pain which arises as a response to tissue damage, is characterized by having a low activation threshold and is a consequence of the activity of molecular mediators of the inflammatory process in the sensitization of nociceptors (Schaible. Langenbecks Arch. Surg. 2004, 389, 237 ).
- neuropathic pain has a high prevalence and impact today (Smith. Pain. 2020, 161, 1:S127; Cavalli. Int. J. Immunopathol. Pharmacol. 2019, 33:2058738419838383; Bouhassira. Rev Neurol (Paris).
- Neuropathic pain is defined by the International Association for the Study of Pain (IASP) as pain initiated or caused by a dysfunction or primary injury in the central and/or peripheral nervous system (Dworkin. Clin. J. Pain, 2002, 18(6), 343).
- Central neuropathic pain comes from injuries to the spinal cord or diseases of the central nervous system, such as multiple sclerosis or Parkinson's disease (Ducreux. Brain, 2006, 129, 963).
- Peripheral neuropathic pain can be caused by trauma, metabolic disorders, chemical neurotoxicity, infection or tumor invasion, among others.
- neuropathic pain syndromes are chemotherapy-induced neuropathic pain, complex regional pain, neuropathy related to viral infection, neuropathy secondary to tumor infiltration, neuropathy diabetic, phantom limb pain, postherpetic neuralgia, trigeminal neuralgia, and postsurgical neuralgia (Pak. Curr. Pain Headache Rep., 2018, 22(2), 9).
- Voltage-gated sodium channels play a fundamental role in the transmission of pain-related stimuli. These channels are activated in response to membrane depolarization, allowing the generation and propagation of action potentials in neurons (and other electrically excitable cells) by controlling the flow of sodium ions across membranes.
- voltage-gated sodium channels are heteromeric transmembrane proteins consisting of an a subunit and two auxiliary p subunits. The a subunit is organized into four homologous domains (I-IV), each with six transmembrane segments (S1-S6). The S4 segment of each domain is characterized by a conserved region of arginine residues, which act as sensors of the intra- and extracellular electrical environment of the neuron.
- tetrodotoxin tetrodotoxin
- the a subunits can also be classified according to their susceptibility to blockade by tetrodotoxin (TTX), being classified as sensitive to tetrodotoxin (Nav 1.1, Nav 1.2, Nav 1.3, Nav 1.4, Nav 1.6 and Nav 1.7) or resistant to tetrodotoxin (Nav 1.5, Nav 1.8 and Nav 1.9) (Lera-Ruiz. J. Med. Chem., 2015, 58(18), 7093; Bagal. J. Med. Chem., 2013, 56(3), 593).
- TTX tetrodotoxin
- Each of these subunits has a different profile of expression and function, so that some of them are essential for the proper functioning of organs such as the heart and/or brain. Therefore, the non-selective blocking of these channels is related to several types of adverse effects, such as migraine, epilepsy, paralysis and muscular and cardiac syndromes, among others (Bagal. J. Med. Chem., 2013, 56(3), 593; Bagal. Channels, 2015, 9(6), 360).
- Nav channels 1.1, 1.2 and 1.3 are mainly expressed in the brain.
- Nav 1.4 and Nav 1.5 channels are mainly in skeletal and cardiac muscles, respectively.
- Nav 1.6 channels are expressed in the central and peripheral nervous system, while Nav 1.9 channels are selectively expressed in type C nociceptive fibers in the dorsal root ganglion.
- Nav 1.7 and Nav 1.8 channels are mainly found in the peripheral nervous system and are directly related to pain transmission processes (Lei. Drug Discovery Today, 2019, 24(7), 1389; Bagal. Channels (Austin), 2015, 9(6), 360; Lera-Ruiz.
- Nav 1.7 sodium channels are widely expressed in the olfactory epithelium, sympathetic ganglion and dorsal root ganglion, predominantly in C and A ⁇ 5 nociceptive fibers.
- a large amount of evidence supports the important role of Nav 1.7 sodium channels in pain transmission processes.
- gain-of-function mutations in the gene (SCN9A) which encodes the Nav 1.7 sodium channel, are associated with extreme pain disorders such as congenital insensitivity to pain, paroxysmal extreme pain disorder, and primary erythromelalgia.
- mutations related to loss of function of the gene (SCN9A) are related to congenital insensitivity to pain in individuals who, in general terms, are free from motor or cognitive impairment (Vetter. Pharmacology & Therapeutics, 2017, 172, 73; Ahuja. Science, 2015, 350(6267), 1491; Chem., 2019, 62, 831; Bankar. Cell Reports, 2018, 24, 3133).
- Nav 1.8 sodium channels show greater expression in the peripheral nervous system, largely (but not exclusively) in type C nociceptive fibers in the dorsal root ganglion. Recent evidence includes elevated expression levels of Nav 1.8 in chronic pain states, data with Nav 1.8 knockout animals, and analgesic activity of Nav 1.8-specific desensitizing oligodeoxynucleotides, among others (Brown. Bioorg. Med. Chem., 2019, 27( 1), 230; , 407; Zhang. Neuropharmacology, 2010, 59, 201 and 207), support the role of the Nav 1.8 sodium channel in the development and process of pain-related pathologies (Kingwell. Nat. Rev. Drug Discov., 2019, 18, 321; Law. Drug Discovery Today, 2019, 24(7), 1389; , 7093).
- the present invention refers to hydroxamates as an alternative and/or complement to the treatment of pain-related diseases.
- the present invention discloses hydroxamates with blocking activity of Nav 1.7 and/or 1.8 channels, against pain-related pathologies, in addition to related compositions, uses, kits, treatment methods and preparation processes.
