the JA pathway was rarely investigated for newplant activators. In this study, starting from JA and its analogs, based on the molecular three-dimensional shape and pharmacophore similarity comparison (SHAFTS), a new lead compound, pyrrolidone, as a new scaffold of plant activators was predicted and a series of 1-phenyl-5-pyrrolidone-3-carboxylic acid derivatives were designed and synthesized. The
affinity adenosine receptor that functions by Gs mediated elevation of cAMP and subsequent downstream signaling. The receptor has been implicated in lung inflammatory disorders like COPD and asthma. Several potent and selective A2BAdoR antagonists have been reported in literature, however most of the compounds suffer from poor pharmacokinetic profile. Therefore, with the aim to identify novel, potent and
