  Solution-phase parallel synthesis of 5-carboxamido 1-benzyl-3-(3-dimethylaminopropyloxy)-1H-pyrazoles as activators of soluble guanylate cyclase with improved oral bioavailability

  摘要：

  A lipophilicity constrained library of 5-carboxamido 1-benzyl-3-(3-dimethylaminoproploxy)-1H-pyrazoles was prepared by solution-phase parallel synthesis with removal of acidic by-products using the strongly basic MP-carbonate resin. Compounds show both activation of soluble guanylate cyclase and inhibition of platelet aggregation. Compound 12 also shows 22% oral bioavailability in rats. (C) 2001 Elsevier Science Ltd.

  Synthesis and Biological Evaluation of Novel Pyrazoles and Indazoles as Activators of the Nitric Oxide Receptor, Soluble Guanylate Cyclase

  摘要：

  Database searching and compound screening identified 1-benzyl-3-(3-dimethylaminopropyloxy)-indazole (benzydamine, 3) as a potent activator of the nitric oxide receptor, soluble guanylate cyclase. A comprehensive structure-activity relationship study surrounding 3 clearly showed that the indazole C-3 dimethylaminopropyloxy substituent was critical for enzyme activity. However replacement of the indazole ring of 3 by appropriately substituted pyrazoles maintained enzyme activity. Compounds were evaluated for inhibition of platelet aggregation and showed a general lipophilicity requirement. Aryl-substituted pyrazoles 32, 34, and 43 demonstrated potent activation of soluble guanylate cyclase and potent inhibition of platelet aggregation. Pharmacokinetic studies in rats showed that compound 32 exhibits modest oral bioavailability (12%). Furthermore 32 has an excellent selectivity profile notably showing no significant inhibition of phosphodiesterases or nitric oxide synthases.

  The present invention describes the use of pyrazole or indazole derivates as activators of soluble guanylate cyclase. Some compounds disclosed are novel. All activators are vasodilators and/or inhibit platelet aggregation and are therefore useful in the treatment of peripheral vascular diseases such as hypertension, angina pectoris or atherosclerosis, or in the treatment of prevention of glaucoma, preeclampsia, Raynaud's syndrome, stroke or erectile disfunctions.

  本发明描述了将吡唑或吲唑衍生物用作可溶性鸟苷酸环化酶的激活剂。其中一些化合物是新颖的。所有激活剂均为血管扩张剂和/或抑制血小板聚集剂，因此可用于治疗外周血管疾病，如高血压、心绞痛或动脉粥样硬化，或用于预防青光眼、先兆子痫、雷诺综合征、中风或勃起功能障碍。
