Medicinal Chemistry

Our medicinal chemists use the data generated throughout your program to make informed design decisions. By connecting structure activity relationship (SAR), biological activity, physicochemical properties, and ADME/DMPK data, we help you prioritize the chemistry most likely to improve your overall compound profile. This means your medicinal chemistry program is focused on learning and progression, rather than simply increasing the number of compounds made.

Where are you in your drug discovery journey?

From hit identification and hit-to-lead through to lead optimization and candidate selection, Concept Life Sciences provides the specialist medicinal chemistry expertise and flexible capacity you need to keep your drug discovery program moving. Wherever you are in your program, we help turn your data into your next decision.

‍

Iterate and optimize: Every cycle generates learning that informs the next compound design.

How does the DMTA cycle accelerate your program?

Interesting chemistry can quickly become a bottleneck when you lack the capacity, expertise, or data needed to decide what to make, test, and progress. Medicinal chemistry expertise helps you turn promising compounds into stronger hits, leads, and candidates through an iterative Design-Make-Test-Analyze (DMTA) approach.

By connecting compound design and synthesis with biology, computer aided drug design (CADD) and ADME/DMPK, you can understand not only whether a molecule works, but why it works, where it falls short and what to make next.

‍

The result: fewer uninformative compounds, more actionable data, and a clearer path towards candidate selection.

Medicinal chemistry built around your program

Do you need additional medicinal chemistry capacity?

Extend your existing team without building the capability in-house.

Our medicinal chemists can support compound design, synthesis, SAR development, and optimization as an extension of your team. This is particularly valuable for biotech and virtual biotech companies that need specialist chemistry expertise or laboratory capacity without the cost and commitment of establishing a complete internal function.

Do you need to turn hits into a lead series?

Build the SAR and compound profile needed to decide which chemistry deserves further investment.

We design and synthesize focused compounds to explore chemical space, test SAR hypotheses, and address early drug-like properties. Our hit-to-lead expertise connects medicinal chemistry with biological screening and ADME/DMPK to support informed progression.

Are your leads potent but difficult to progress?

Optimize the whole compound profile, not potency in isolation. Lead optimization requires balancing multiple properties simultaneously. We can help optimize:

• Potency
• Selectivity
• Efficacy
• Target engagement
• Solubility
• Lipophilicity
• Permeability
• Metabolic stability
• Chemical stability
• Molecular weight
• pKa
• Other physicochemical and ADME/DMPK properties

The objective is to identify compounds with the overall characteristic properties needed for progression, not just the most potent.

What happens when chemistry, biology, and ADME/DMPK work together?

What if every compound you make could tell you what to make next?

Disconnected data can make it difficult to know what your next experiment should be. At Concept Life Sciences, medicinal chemistry can connect directly with biology, CADD, and ADME/DMPK, allowing our scientists to interpret the complete compound profile and use that information to guide the next design decision.

This integrated approach helps shorten the gap between generating data and acting on it, supporting faster and more informed decisions throughout hit expansion, hit-to-lead, and lead optimization.

Medicinal Chemistry FAQs

Q: What is medicinal chemistry?

A: Medicinal chemistry is the design, synthesis, and optimization of chemical compounds with the aim of developing them into medicines. It combines chemistry with biological and drug development data to understand how changes in molecular structure affect potency, selectivity, physicochemical properties, ADME, and other characteristics important for candidate progression.

Q: What are medicinal chemistry services?

A: Medicinal chemistry services provide specialist support for designing, synthesizing, and optimizing compounds throughout drug discovery. Services can include compound design, synthesis, SAR development, hit-to-lead, lead optimization, and candidate selection.

Q: What is hit-to-lead medicinal chemistry?

A: Hit-to-lead medicinal chemistry turns promising hit compounds into more thoroughly characterized lead series. This typically involves expanding chemical series, establishing SAR, exploring chemical space, and improving early drug-like properties.

Q: What is lead optimization?

A: Lead optimization is the process of improving a lead compound's overall profile so it is suitable for progression towards a development candidate. Medicinal chemists optimize properties such as potency, selectivity, efficacy, solubility, permeability, metabolic stability, and other ADME/DMPK characteristics.

Q: What is the Design-Make-Test-Analyze cycle?

A: DMTA is an iterative drug discovery process in which compounds are designed, synthesized, tested, and analyzed, with the results informing the next round of compound design. The approach creates a continuous learning cycle for compound optimization.

Q: Can you work with our existing biology and ADME/DMPK data?

A: Yes. Concept Life Sciences can connect medicinal chemistry with biological and ADME/DMPK data to help interpret the overall compound profile and determine what to make next.
