Hypothalamic CAMKK2 represents a potential mechanism for chemically affecting satiety and promoting weight loss in clinically obese patients. Single-digit nanomolar inhibitors of CAMKK2 were identified in three related ATP-competitive series. Limited optimization of kinase selectivity, solubility, and pharmacokinetic properties were undertaken on all three series, as SAR was often transferrable. Ultimately
下丘脑CAMKK2代表了化学影响饱腹感和促进临床肥胖患者体重减轻的潜在机制。在三个相关的ATP竞争系列中鉴定了CAMKK2的一位数纳摩尔抑制剂。由于SAR通常是可转移的,因此对这三个系列进行了激酶选择性,溶解度和药代动力学特性的有限优化。最终,对2,4-二芳基7-氮杂吲哚进行了优化,以提供一种工具分子,该工具分子可有效抑制下丘脑衍生的细胞系中AMPK磷酸化,可口服生物利用,并穿过血脑屏障。当在啮齿动物中口服时,化合物4 t限制了生长素释放肽诱导的食物摄入。
