Transforming growth factor-beta (TGF-beta) is a potent fibrotic factor responsible for the synthesis of extracellular matrix (ECM) and is implicated as the major determinant in pathogenesis of chronic fibroses, including kidney. The novel small compound SMP-534 reduced ECM production induced by TGF-beta in fibroblast cells. SMP-534 inhibited(More)
We designed and synthesized a series of dihydroquinazolinone derivatives as selective M1 and M4 muscarinic acetylcholine receptors agonists. Introduction of the N-carbethoxy piperidine unit into a HTS hit compound followed by optimization of the amine linker and the carbamoyl moiety led to the identification of compound 1 as a potential candidate. The(More)
Activation of the M1 and M4 muscarinic acetylcholine receptors is thought to play an important role in improving the symptoms of schizophrenia. However, discovery of selective agonists for these receptors has been a challenge, considering the high sequence homology and conservation of the orthosteric acetylcholine binding site among muscarinic acetylcholine(More)
