Immunopharmacology Ligand
Compound class: Synthetic organic
Comment: Lorecivivint (SM04690, formerly adavivint) is a Wnt pathway inhibitor being developed by Samumed for immunomodulatory potential. It acts downstream of β-catenin, and its molecular targets are the intranuclear kinases CLK2 and DYRK1A through which it inhibits phosphorylation of serine/arginine-rich splicing factors, and SIRT1 and FOXO1 respectively [3]. Wnt signalling is upregulated in tissues from osteoarthritic joints, and drives disease pathologies including inflammation [5]. Wnt pathway inhibition by lorecivivint is being investigated as a disease-modifying treatment for osteoarthritis.
SM04690 is example 10 as claimed in patent US20160297812 [4]. The chemical structure shown here was produced using the IUPAC name submitted to the WHO for the INN adavivint (via SMILES generated using Chemicalize) which was later renamed as lorecivivint. This SMILES string resolves to PubChem CID 123710737, although some of the double bonds in the molecule are not fully resolved, when compared to the images in US20160297812. CID 89837869 is an alternative representation.

Ligand Activity Visualisation Charts

These are box plot that provide a unique visualisation, summarising all the activity data for a ligand taken from ChEMBL and GtoPdb across multiple targets and species. Click on a plot to see the median, interquartile range, low and high data points. A value of zero indicates that no data are available. A separate chart is created for each target, and where possible the algorithm tries to merge ChEMBL and GtoPdb targets by matching them on name and UniProt accession, for each available species. However, please note that inconsistency in naming of targets may lead to data for the same target being reported across multiple charts.

2D Structure

An image of the ligand's 2D structure. For small molecules with SMILES these are drawn using the NCI/CADD Chemical Identifier Resolver. Click on the image to access the chemical structure search tool with the ligand pre-loaded in the structure editor. For other types of ligands, e.g. longer nucleotides and peptides, a manually drawn representation of the molecule may be provided.

SMILES / InChI / InChIKey

SMILES (Simplified Molecular Input Line Entry Specification) A specification for unambiguously describing the structure of chemical molecules using short ASCII strings. Canonical SMILES specify a unique representation of the 2D structure without chiral or isotopic specifications. Isomeric SMILES include chiral specification and isotopes.

Standard InChI (IUPAC International Chemical Identifier) and InChIKey InChI is a non-proprietary, standard, textual identifier for chemical substances designed to facilitate linking of information and database searching. An InChIKey is a simplified version of a full InChI, designed for easier web searching.

Immunopharmacology Comments
In the joint, the Wnt pathway helps to control tissue homeostasis through regulation of mesenchymal stem cell differentiation into chondrocytes and osteoblasts, which is crucial for cartilage tissue repair and regeneration within joints. In OA joints, increased Wnt signaling leads to cartilage degradation [1,6]. Pharmacological modulation (inhibition) of Wnt signaling may provide a novel disease-modifying osteoarthritis drug mechanism (DMOAD), that will ameliorate cartilage dysregulation associated with OA [7]. This mechanism would provide an alternative therapeutic strategy for OA, which until now has relied on temporary relief of signs and symptoms using anti-inflammatory drugs (NSAIDs) and other pain medications.
