[Means for Solution] A bicyclic heterocyclic compound (the bicyclic heterocycle is formed when a cyclohexane ring is fused with a 5- to 6-membered monocyclic heterocycle that has only a nitrogen atom as a hetero atom) substituted with an acylamino group such as a (hetero)aroylamino group or the like or a pharmaceutically acceptable salt thereof was found to have an excellent selective inhibitory action against 11β-HSD1. Accordingly, the bicyclic heterocyclic compound of the present invention can be used for treating dementia, schizophrenia, depression, pain (particularly, neuropathic pain or fibromyalgia), diabetes (particularly, type II diabetes mellitus), insulin resistance, and the like.

  Hereditary angioedema (HAE) is a rare genetic disorder in which patients experience sudden onset of swelling in various locations of the body. HAE is associated with uncontrolled plasma kallikrein (PKa) enzyme activity and generation of the potent inflammatory mediator, bradykinin, resulting in episodic attacks of angioedema. Herein, we disclose the discovery and optimization of novel small molecule

  The Wnt family of proteins are secreted signaling proteins that play key roles in regulating cellular functions. Recently, carboxylesterase Notum was shown to act as a negative regulator of Wnt signaling by mediating the removal of an essential palmitoleate. Here we disclose two new chemical scaffolds that inhibit Notum enzymatic activity. Our approach was to create a fragment library of 250 acids for screening against Notum in a biochemical assay followed by structure determination by X-ray crystallography. Twenty fragments were identified as hits for Notum inhibition, and 14 of these fragments were shown to bind in the palmitoleate pocket of Notum. Optimization of 1-phenylpyrrole 20, guided by structure-based drug design, identified 20z as the most potent compound from this series. Similarly, the optimization of 1-phenylpyrrolidine 8 gave acid 26. This work demonstrates that inhibition of Notum activity can be achieved by small, drug-like molecules possessing favorable in vitro ADME profiles.
