The discovery of a selective, high affinity A2B adenosine receptor antagonist for the potential treatment of asthma
摘要:
Adenosine has been suggested to play a role in asthma, possibly via activation of A(2B) adenosine receptors on mast cells and other pulmonary cells. We describe our initial efforts to discover a xanthine based selective A(2B) AdoR antagonist that resulted in the discovery of CVT-5440, a high affinity A(2B) AdoR antagonist with good selectivity (A(2B) AdoR K-i = 50 nM, selectivity A(1) > 200: A(2A) > 200: A(3) > 167).

bioisosterism replacement strategies were used to design and synthesize novel tetrahydrophthalimide derivativescontaining oxadiazole/thiadiazole moieties, and their inhibitory effects on Nicotiana tobacco PPO (NtPPO) and herbicidalactivity were evaluated. Among them, compounds B11 (Ki = 9.05 nM) and B20 (Ki = 10.23 nM) showed significantly better inhibitory activity against NtPPO than that against flumiclorac-pentyl
原卟啉原氧化酶(PPO,EC 1.3.3.4)在新型抑制剂的开发中具有很高的地位。为了开发新型高效PPO抑制剂,采用活性子结构连接和生物电子等排取代策略设计合成了新型含恶二唑/噻二唑结构的四氢邻苯二甲酰亚胺衍生物,并评价了其对烟草PPO( Nt PPO)的抑制作用和除草活性。其中,化合物B11 ( K i = 9.05 nM)和B20 ( K i = 10.23 nM)对Nt PPO的抑制活性明显优于对氟氯酸戊酯( K i = 46.02 nM)的抑制活性。同时,化合物A20和B20在37.5 g ai/ha时对三种杂草(苘麻、反枝苋和马齿苋)100%有效。值得观察的是,化合物B11在18.75和9.375 g ai/ha时对三种杂草(苘麻、反枝苋和马齿苋)的有效效果超过90%。对于水稻、玉米和小麦来说,150 g ai/ha 的剂量比氟氯酸戊酯更安全。此外,分子对接结果表明,化合物B11能够稳定地与Nt
Phenoxymethyl 1,3-oxazoles and 1,2,4-oxadiazoles as potent and selective agonists of free fatty acid receptor 1 (GPR40)
A screening hit that showed a weak (EC50 = 18 mu M), partial agonistic effect on GPR40 was used a prototype for expedited hit expansion effort using a set of advanced building blocks. The latter yielded several 1,3-oxazoles and 1,2,4-oxadiazoles with significantly improved potency (best EC50 = 0.058 mu M). The lead compounds in each chemotype showed a very good ADME profile (aqueous solubility, plasma protein binding, microsomal stability and membrane permeability) and no appreciable inhibition of key cytochromes P450. The compounds reported are significant new starting points for further preclinical development of future diabetic agents with a mechanism of action for which a first-in-class agent is yet to be approved.
