Embodiment 1

[0785] Example 1, N-(5-(2,3-dihydrobenzo[b][1,4]dioxin-6-amido)-2-methylphenyl)quinoline-6- Formamide

[0786] 2-(7-Aza-1H-benzotriazol-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (HATU, 3.34 g, 8.79 mmol) was added to 6- A solution of quinolincarboxylic acid (1.34 g, 7.74 mmol) and N,N-diisopropylethylamine (DIEA, 2.76 mL, 15.8 mmol) in dry DMF (40 mL). The reaction mixture was stirred for 6 min, after which compound 2 (2.00 g, 7.03 mmol) was added. The reaction mixture was stirred overnight at rt, diluted with water and the resulting precipitate was isolated by filtration, washed with water and dried to afford the title compound (3.09 g, 100%) as an off-white solid. 1 HNMR(500MHz,DMSO)δ10.18(s,1H),10.08(s,1H),9.02(dd,J=4.2,1.7Hz,1H),8.67(d,J=2.0Hz,1H),8.54( dd,J=8.4,1.9Hz,1H),8.29(dd,J=8.8,2.1Hz,1H),8.15(d,J=8.8Hz,1H),7.88(d,J=2.2Hz,1H), 7.65(dd, J=8.3,4.2Hz,1H),7.59(dd,J=8.2,2.2Hz,1H),7.54(d,J=2.2Hz,1H),7.51(dd,J=8.4,2.2Hz , 1H), 7.25 (d, J=8.4Hz, 1H), 6.98...

Abstract

The present invention relates to compounds of formula I wherein A1, A2 R4 and Q are as defined herein. The compounds of the present invention are inhibitors of heat shock factor 1 (HSF1). In particular, the present invention relates to the use of these compounds as therapeutic agents for the treatment and/or prevention of proliferative diseases, such as cancer. The present invention also relates to processes for the preparation of these compounds, and to pharmaceutical compositions comprising them.

Description

[0001] introduction [0002] The present invention relates to novel compounds that act as inhibitors of heat shock factor 1 (HSF1) activity. The invention also relates to processes for the preparation of the compounds defined herein, pharmaceutical compositions comprising them, and their use in the treatment of HSF1 -mediated conditions or diseases such as cancer, autoimmune and viral diseases. Background of the invention [0003] Cancer arises from uncontrolled and unregulated cell proliferation. Precisely what causes cells to become malignant and proliferate in an uncontrolled and unregulated manner has been the focus of intense research in recent decades. This research has led to the identification of many molecular targets associated with key metabolic pathways known to be associated with malignancy. [0004] Heat shock factor 1 (HSF1) is one such target molecule. HSF1 is a master regulator of the heat shock response, in which multiple genes are induced in response to i...
