Direct access to and operation of cutting-edge UPLC-HRMS platforms by expert analytical chemists, guaranteeing definitive, highly accurate structural elucidation of every primary metabolite.
Soft Spot Identification Service
Creative Biolabs delivers the highest-resolution structural and mechanistic intelligence for your drug discovery program. We provide a consolidated, dual-focus analysis that identifies not only the most druggable site on your target (efficacy soft spot) but also the weakest metabolic link in your compound (metabolic soft spot). Clients can expect to gain accelerated lead optimization cycles, definitive data for structure-activity relationship (SAR) decisions, and a substantial de-risking of their pipeline by eliminating compounds destined for metabolic failure early on.

Soft Spot Identification
The successful development and marketing of a new drug requires a complex process, including the selection of drug targets, the screening of lead compounds, the determination of clinical candidate compounds, the confirmation of clinical efficacy, and the safety evaluation of drugs. When the target screening obtains a molecular structure with in vitro pharmacodynamic activity, it is hoped that it can have the appropriate exposure amount and duration of action in vivo, and the rapid metabolic clearance of the drug tends to reduce the exposure of the drug. To improve the properties of rapid metabolism, it is important to be able to identify the metabolic sites of compound molecules and protect them. The chemical groups or individual atoms of compounds that are prone to metabolic reactions in vivo/in vitro are called "soft spots of metabolism".

Dramatically Increased Bioavailability
Implementation of the Creative Biolabs' service yielded substantial enhancements in the stability of our orally bioavailable kinase inhibitor candidates. The rigorous identification of a labile methyl group, precisely determined via mass spectrometry, facilitated the rational synthesis of a metabolically stable analog. – J**s D**n. -
Precise Allosteric Targeting
Using Creative Biolabs' soft spot identification service in our research has significantly improved the rational design of small molecule modulators for a PPI target. The computational structural analysis quickly confirmed a transient pocket that was non-obvious, saving us four months of failed traditional high-throughput screening. – S**h M**r.
FAQs
What is the difference between an efficacy soft spot and a metabolic soft spot?
An efficacy soft spot is a non-redundant weakness in a biological pathway (e.g., an allosteric site) that maximizes therapeutic effect. A metabolic soft spot is a chemically labile group on your compound that causes rapid clearance, minimizing therapeutic exposure. Our service addresses both simultaneously.
How does the single variable incubation technique improve the data quality?
By precisely controlling the incubation time based on the compound's half-life, we ensure only primary metabolites (the immediate and most important causes of clearance) are formed, avoiding complex secondary metabolites. This streamlines the interpretation process, giving you faster, clearer, and more actionable data.
