The present invention is directed to compounds of formula (I),
which antagonize of the effects of melanin-concentrating hormone (MCH) through the melanin concentrating hormone receptor which is useful for the prevention or treatment of eating disorders, weight gain, obesity, abnormalities in reproduction and sexual behavior, thyroid hormone secretion, diuresis and water/electrolyte homeostasis, sensory processing, memory, sleeping, arousal, anxiety, depression, seizures, neurodegeneration and psychiatric disorders.

The invention provides compounds, pharmaceutical compositions comprising such compounds and methods of using such compounds to treat or prevent diseases or disorders associated with the activity of GPR119; such as, but not limited to, diabetes, obesity and associated metabolic disorders. Formula (I) is a compound, in which A can have up to 2 ring —CH2- group substituted with —C(O)— and can be partially unsaturated with up to 2 double bonds; Wi and W2 are independently selected from CR10 and N; wherein R10 is selected from hydrogen and C1_6alkyl; Yi is selected from NRn, O and S; wherein Rn is selected from hydrogen and C1_6alkyl; Y2 and Y3 are independently selected from CH and N; Y4 is selected from CH2, OCH2 and NR15; wherein R15 is selected from hydrogen and C1_6alkyl; or the pharmaceutically acceptable salts thereof.
multiple sclerosis, monitor its evolution, and support drug development. Radiotracers based on N,N-dimethylaminostilbene (MeDAS) fluorinatedanalogs have been designed for myelin PET imaging but were never translated to humans. We have synthesized three original fluorinatedanalogs of MeDAS with low metabolic rates for which binding to myelin in a healthy rat brain was demonstrated by fluorescence microscopy

of stimulator of interferon genes (STING)-mediated innate immunity has emerged as a novel therapeutic approach in cancer therapy. 2′,3′-Cyclic GMP–AMP (cGAMP) is a natural STINGagonist; however, cGAMP is subjected to endogenous degradation by ecto-nucleotide pyrophosphatase phosphodiesterase 1 (ENPP1). To improve the ICI response rate, we developed 29f, a novel ENPP1 inhibitor with phthalazin-1(2H)-one
T 细胞发炎的肿瘤微环境的缺乏限制了免疫检查点抑制剂 (ICIs) 的功效。激活干扰素基因刺激物(STING)介导的先天免疫已成为癌症治疗中的一种新型治疗方法。 2′,3′-Cyclic GMP–AMP (cGAMP) 是一种天然的 STING 激动剂;然而,cGAMP 会被外核苷酸焦磷酸酶磷酸二酯酶 1 (ENPP1) 内源性降解。为了提高ICI缓解率,我们开发了29f ,一种以酞嗪-1(2 H )-one为核心支架的新型ENPP1抑制剂。 29f在体外抑制 ENPP1 引起的 cGAMP 水解 (IC 50 = 68 nM),并增强免疫细胞和肿瘤细胞中 STING 介导的 I 型干扰素反应。 29f表现出优异的代谢稳定性和生物利用度( F = 65%)。口服29f在 CT26 同基因模型中促进肿瘤生长抑制,并增加抗 PD-L1 反应。此外, 29f诱导的免疫记忆可防止肿瘤再攻击时复发,表明29f具有良好的治疗潜力。
