Definitions

  • the present teachings relate to certain carboxylic acid amides and related derivatives, processes for their preparation, and their use in therapeutic treatments.
  • ion channels that permit these changes are proteinaceous pores consisting of one or multiple subunits, each containing two or more membrane-spanning domains. Most ion channels have selectivity for specific ions, primarily Na + , K + , Ca 2+ , or Cl " , by virtue of physical preferences for size and charge. Electrochemical forces, rather than active transport, drive ions across membranes, thus a single channel may allow the passage of millions of ions per second.
  • Channel opening, or "gating" is tightly controlled by changes in voltage or by ligand binding, depending on the subclass of channel. Ion channels are attractive therapeutic targets due to their involvement in so many physiological processes, yet the generation of drugs with specificity for particular channels in particular tissue types remains a major challenge.
  • Voltage-gated ion channels open in response to changes in membrane potential. For example, depolarization of excitable cells such as neurons results in a transient influx of Na + ions, which propagates nerve impulses. This change in membrane potential is sensed by voltage-gated K + channels, which then allow an efflux of K + ions. The efflux of K + ions repolarizes the membrane. Other cell types rely on voltage-gated Ca 2+ channels to generate action potentials. Voltage-gated ion channels also perform important functions in non-excitable cells, such as the regulation of secretory, homeostatic, and mitogenic processes.
  • Ligand-gated ion channels can be opened by extracellular stimuli such as neurotransmitters (e.g., glutamate, serotonin, and acetylcholine), or intracellular stimuli (e.g., cAMP, Ca 2+ , and phosphorylation).
  • extracellular stimuli such as neurotransmitters (e.g., glutamate, serotonin, and acetylcholine), or intracellular stimuli (e.g., cAMP, Ca 2+ , and phosphorylation).
  • the Ca v 2 family of voltage-gated calcium channels consists of 3 main subtypes Ca v 2.1 (P or Q-type calcium currents), Ca v 2.2 (N-type calcium currents), and Ca v 2.3 (R-type calcium currents). These currents are found almost exclusively in the central nervous system (CNS), peripheral nervous system (PNS) and neuroendocrine cells, and constitute the predominant forms of presynaptic voltage-gated calcium current. Presynaptic calcium entry is modulated by many types of G-protein coupled receptors (GPCRs) and modulation of Ca v 2 channels is a widespread and highly efficacious means of regulating neurotransmission.
  • GPCRs G-protein coupled receptors
  • the subunit composition of the Ca v 2 channels is defined by their Ci 1 subunit, which forms the pore and contains the voltage-sensing gates (0 ⁇ 2.1 , c ⁇ i2.2, and ⁇ i2.3, also known as ⁇ i A , ⁇ 1B , and ⁇ 1E , respectively) and the ⁇ and ⁇ 2 subunits.
  • ion channel function can have dramatic clinical consequences. Long QT syndrome, epilepsy, cystic fibrosis, and episodic ataxia are a few examples of heritable diseases resulting from mutations in ion channel subunits. Toxic side effects such as arrhythmia and seizure, which can be triggered by certain drugs, can be due to interference with ion channel function (Sirois, J. E. and Atchison, W. D. (1996), Neurotoxicology, 17(1 ): 63-84; Keating, MT. (1996), Science, 272: 681-685).
  • Drugs are useful for the therapeutic modulation of ion channel activity, and have applications in treatment of many pathological conditions, including hypertension, angina pectoris, myocardial ischemia, asthma, bladder overactivity, alopecia, pain, heart failure, dysmenorrhea, type Il diabetes, arrhythmia, graft rejection, seizure, convulsions, epilepsy, stroke, gastric hypermotility, psychoses, cancer, muscular dystrophy, and narcolepsy (Coghlan, MJ. et al. (2001 ), J. Med. Chem., 44: 1627-1653; Ackerman, M.J. and Clapham, D. E. (1997), N. Eng. J. Med., 336: 1575-1586).
  • pathological conditions including hypertension, angina pectoris, myocardial ischemia, asthma, bladder overactivity, alopecia, pain, heart failure, dysmenorrhea, type Il diabetes, arrhythmia, graft rejection, seizure,
  • Therapeutic modulation of Ca v 2 channel activity has applications in treatment of many pathological conditions. All primary sensory afferents provide input to neurons in the dorsal horns of the spinal cord and in dorsal root ganglia neurons in the dorsal horn, and calcium influx through Ca v 2.2 channels triggers the release of neurotransmitters from presynaptic nerve terminals in the spinal cord. Hence, blockade of Ca v 2.2 channels is expected to be broadly efficacious because these channels are in a common pathway downstream from the wide variety of receptors that mediate pain (Julius, D. and Basbaum, A.I. (2001 ), Nature, 413: 203-216).
  • Ca v 2.2 channels are found in the periphery and mediate catecholamine release from sympathetic neurons and adrenal chroffin cells. Some forms of hypertension result from elevated sympathetic tone. Ca v 2.2 modulators could be particularly effective in treating this disorder. Although complete block of Ca v 2.2 channels can cause hypotension or impair baroreceptor reflexes, partial inhibition by Ca v 2.2 modulators might reduce hypertension with minimal reflex tachycardia (Uneyama, O. D. (1999), Int. J. MoI. Med., 3: 455-466).
  • Overactive bladder is characterized by storage symptoms such as urgency, frequency, and nocturia, with or without urge incontinence, resulting from the overactivity of the detrusor muscle in the bladder. OAB can lead to urge incontinence.
  • the etiology of OAB and painful bladder syndrome is unknown, although disturbances in nerves, smooth muscle and urothelium can cause OAB (Steers, W., Rev. Urol., 4: S7-S18). There is evidence to suggest that reduction of bladder hyperactivity may be indirectly effected by inhibition of Ca v 2.2 and/or Ca v 1 channels.
  • gabapentin was designed as a metabologically stable GABA mimetic, but most studies find no effect on the GABA receptors.
  • the ⁇ 2 ⁇ subunit of voltage-gated calcium channels has been identified as a high affinity binding site for gabapentin in the CNS. There is evidence that suggests that gabapentin could inhibit neurotransmission in the spinal cord by interfering with the function of the ⁇ 2 ⁇ subunits, thereby inhibiting presynaptic calcium currents.
