The present invention relates to ion channel activating agents. More particularly, the present invention relates to a particular class of chemical compounds that has proven useful as openers of SK
Ca
and IK
Ca
channels. In further aspects, the present invention relates to the use of these SK/IK channel activating agents for the manufacture of medicaments and pharmaceutical compositions comprising the SK/IK channel activating agents. The SK/IK channel activating agents of the invention are useful for the treatment or alleviation of diseases and conditions associated with the SK/IK channels, in particular respiratory diseases such as asthma, cystic fibrosis, chronic obstructive pulmonary disease and rhinorrhea, convulsions, vascular spasms, coronary artery spasms, renal disorders, polycystic kidney disease, bladder spasms, urinary incontinence, bladder outflow obstruction, irritable bowel syndrome, gastrointestinal dysfunction, secretory diarrhea, ischaemia, cerebral ischaemia, ischaemic heart disease, angina pectoris, coronary heart disease, traumatic brain injury, psychosis, anxiety, depression, dementia, memory and attention deficits, Alzheimer's disease, dysmenorrhea, narcolepsy, Reynaud's disease, intermittent claudication, Sjorgren's syndrome, migraine, arrhythmia, hypertension, absence seizures, myotonic muscle dystrophia, xerostomi, diabetes type II, hyperinsulinemia, premature labor, baldness, cancer, and immune suppression.
本发明涉及离子通道激活剂。更具体地说,本发明涉及一类特定的化合物,已被证明对SKCa和IKCa通道的开放具有用处。在进一步方面,本发明涉及利用这些SK/IK通道激活剂制造药物和包含SK/IK通道激活剂的药物组合物。本发明的SK/IK通道激活剂对于治疗或缓解与SK/IK通道相关的疾病和症状非常有用,特别是呼吸道疾病,如哮喘、囊性纤维化、慢性阻塞性肺疾病和鼻涕,痉挛、血管痉挛、冠状动脉痉挛、肾脏疾病、多囊肾病、膀胱痉挛、尿失禁、膀胱排空阻塞、肠易激综合征、胃肠功能障碍、分泌性腹泻、缺血、脑缺血、缺血性心脏病、心绞痛、冠心病、创伤性脑损伤、精神病、焦虑、抑郁、痴呆、记忆和注意力缺陷、阿尔茨海默病、痛经、嗜睡症、雷诺氏病、间歇性跛行、斯约格伦综合征、偏头痛、心律失常、高血压、缺席性癫痫发作、肌肉肌无力、干燥综合征、2型糖尿病、胰岛素过多症、早产、秃头、癌症和免疫抑制。
