Compound class: Synthetic organic
Comment: Inavolisib (GDC-0077) is a potent and selective, orally available PI3K-p110α (PIK3CA) inhibitor, with antineoplastic activity [2,4]. It is example 101 in patent US20170015678 (where it is named (S)-2-((2-((S)-4-(difluoromethyl)- 2-oxooxazolidin-3-yl)-5,6- dihydrobenzo[f]imidazo[1,2- d][1,4]oxazepin-9- yl)amino)propanamide) [1]. GDC-0077 is one of the agents in Genentech's oncology discovery pipeline. Inavolisib's mechanism of action includes the ability to target oncogenic mutant PI3K-p110α for degradation, in addition to its enzyme inhibitory activity [2].

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.

Physico-chemical Properties

Calculated molecular properties are available for small molecules and natural products (not peptides). Properties were generated using the Chemistry Development Kit (CDK) (Willighagen EL et al. Journal of Cheminformatics vol. 9:33. 2017, doi:10.1186/s13321-017-0220-4; https://cdk.github.io/). All properties were selected to enable the prediction of the Lipinski Rule-of-Five profile or ‘druglikeness’ for each ligand. For more info on each category see the help pages.

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.

Summary of Clinical Use Click here for help
Inavolisib (GDC-0077) was advanced to clinical evaluation in advanced solid tumours. It is being used to target tumours (principally breast cancers) that harbour PIK3CA mutations that are predictive of a clinical response. The FDA approved inavolisib (in combination with palbociclib and fulvestrant) to treat advanced hormone receptor +ve, HER2 -ve, PIK3CA mutation +ve breast cancer in October 2024.
Mechanism Of Action and Pharmacodynamic Effects Click here for help
GDC-0077 binds to and inhibits PI3K family kinases, including activating mutations in the catalytic alpha isoform PIK3CA (PI3Kα). PIK3CA is frequently mutated in a variety of cancer cell types and this underlies the dysregulation of the PI3K pathway that plays a key role in cancer cell growth and invasion. Pharmacological inactivation of the PI3K pathway inhibits growth and survival of PI3K-overexpressing tumour cells
