Frequently Asked Questions
What does the By Target/Pathway/Disease listing cover?
It groups compounds associated with targets in By Target/Pathway/Disease, organised so you can move from the pathway to an individual target and then to a specific chemotype. Each entry carries structure, CAS number, and reported activity.
How is By Target/Pathway/Disease organised?
By Target/Pathway/Disease is broken down into Compound Libraries, PROTACs, molecular glues and other degraders and Antibody-drug Conjugates(ADC). Compounds acting on more than one node appear under each relevant target.
How do I choose compounds for By Target/Pathway/Disease research?
For By Target/Pathway/Disease, pick a well-characterised reference compound for the node you want to perturb, and pair it with a structurally unrelated compound hitting the same target — that is the cleanest way to separate pathway effects from off-target ones. Check potency, selectivity, and cell permeability against your assay format. All products are supplied for professional research and development use only, and are not for use in humans, animals, diagnostics, or therapy.
How do I find a specific compound within By Target/Pathway/Disease?
Search By Target/Pathway/Disease by compound name, CAS number, or SMILES, or drill down through the target listing. Unlisted compounds and bulk quantities: [email protected]. We supply verified businesses, research institutions, universities, and government agencies.
