The present invention pertains to the use of certain 3,4-diarylpyrazoles of formula (I), both in vitro and in vivo, to inhibit heat shock protein 90 (HSP90), and in the treatment of conditions mediated by HSP90, including, for example, cancer; wherein: Ar3 is independently: a C5-20aryl group, and is optionally substituted; Ar4 is independently: a C5-20aryl group, and is optionally substituted; R5 is independently: hydrogen; halo; hydroxy; ether; formyl; acyl; carboxy; ester; acyloxy; oxycarbonyloxy; amido; acylamido; aminocarbonyloxy; tetrazolyl; amino; nitro; cyano; azido; sulfhydryl; thioether; sulfonamido; C1-7alkyl; C3-20heterocycyl; or C5-20aryl; RN is independently: -H; C1-7alkyl; C3-20heterocycyl; or, C5-20aryl; and pharmaceutically acceptable salts, solvates, amides, esters, ethers, chemically protected forms, and prodrugs thereof. The present invention also pertains to such compounds, pharmaceutical compositions comprising such compounds, such compounds for medical use, such compounds for use in the treatment of conditions mediated by HSP90, including, for example, cancer, and use of such compounds in the preparation of medicaments for such treatments.
本发明涉及使用式(I)的特定3,4-二芳基吡唑化合物,无论是体外还是体内,以抑制热休克蛋白90(HSP90)的作用,并用于治疗由HSP90介导的疾病,例如癌症;其中:Ar3独立地表示:C5-20芳基基团,且可选地被取代;Ar4独立地表示:C5-20芳基基团,且可选地被取代;R5独立地表示:氢;卤素;羟基;醚;甲酰基;酰基;羧基;酯基;酰氧基;氧羰基氧基;酰胺基;酰胺氧基;氨基羰氧基;四唑基;氨基;硝基;氰基;偶氮基;硫醇基;硫醚基;磺酰胺基;C1-7烷基;C3-20杂环基;或C5-20芳基;RN独立地表示:-H;C1-7烷基;C3-20杂环基;或C5-20芳基;以及其药学上可接受的盐,溶剂化合物,酰胺,酯,醚,化学保护形式和前药。本发明还涉及这些化合物,包含这些化合物的制药组合物,用于医疗用途的这些化合物,用于治疗由HSP90介导的疾病,例如癌症的这些化合物,以及使用这些化合物制备此类治疗药物的用途。
