Lead Optimization Service

Lead Optimization Service

Lead optimization or drug optimization aims at enhancing the chemical compounds from drug screening to improve potency, and reduce toxicity in humans. As an experienced drug discovery company, Ace Therapeutics can provide the lead optimization services related to for diabetes.

Overview of Lead Optimization

In drug discovery and development, once a chemical compound is identified, the following step is to evaluate its. And then, it comes to lead optimization to maintain favorable properties of lead compounds and improve other parameters.

Optimization Strategies

  • Optimization of Small Molecule Drug
    Drug optimization aims to improve the properties of lead compounds including stability, potency, efficacy, exposure, safety, etc. Potential safety concerns about some lead compounds can be addressed at this stage by modifying or reducing deficiencies in its structure.
  • Optimization of Antibody Therapies
    Reduction of a nonhuman antibody's immunogenicity in humans is a critical step of antibody optimization; otherwise, the therapeutic antibody candidate would induce anti-drug antibodies in humans. Antibody humanization and deimmunization strategies need to be performed.
