Drug discovery and development includes a series of processes, such as the target identification and validation, hit identification, hit-to-lead, and clinical evaluation of drug candidates. In this process, we often encounter problems such as poor medicinal properties, poor pharmacokinetic characteristics, toxicity and side effects of lead compounds. To enhance the ability of lead compounds to be used as drugs and expedite the process of developing new medications, optimization of lead compounds has become the key link of new drug research and development. Lead optimization refers to the process of designing and improving a pre-determined lead compound, involving pharmaceutical chemists using advanced organic synthesis methods or biotechnological methods to modify the structure of the lead compound to improve multiple of the properties described above, while reducing any defects found in its structure. Therefore, in this process, the optimization and evaluation of ADMET properties (absorption, distribution, metabolism, excretion and toxicity) of lead compounds as well as the activity, stability and selectivity of lead compounds become the goal and focus. With extensive capabilities in chemistry, biology, structural biology, ADME and proteomics, we provide wide and world-class services to support the most complex lead optimization projects.

Typical Advanced Equipment
State-of-the-art biophysical testing equipment underlies our lead optimization services and is a strong support for accelerating the development of potential drug candidates. Some typical equipment at our company is described below:
Bio-Layer Interferometry (BLI)
BLI is a label-free optical technique for measuring kinetics and affinity of interactions of biomolecules such as proteins, nucleic acids, and peptides. It measures macromolecular interactions by analyzing the interference pattern of white light reflected from the surface of the biosensor tip.
Surface Plasmon Resonance (SPR)
SPR is a biophysical technique for detecting molecular interactions based on the principles of physical optics. This method can detect the interaction between molecules in real time with high sensitivity. SPR and BLI became key technologies for our lead optimization.
lsothermal Titration Calorimetry (ITC)
ITC is a labeling free method for measuring the binding of any two molecules that release or absorb heat when combined. ITC can be used to measure thermodynamic parameters of biomolecular interactions, including enthalpy, affinity and stoichiometry.
Nuclear Magnetic Resonance (NMR)
NMR studies the structural characteristics, dynamic behaviors and interactions of molecules, thereby revealing the three-dimensional structure of biomolecules.
