SMDC Development Platform

SMDC Development Platform-1

Small molecule-drug conjugates (SMDC) have shown great potential as a new class of targeted drugs for the therapy of rare diseases. Our company is driven by research and innovation and focuses on small molecule drug discovery services for rare diseases. We have launched a new SMDC one-stop platform to provide you with more professional services.

Introduction to SMDC

Small molecule-drug conjugates (SMDC) are a class of therapeutic drugs that combine small molecule drugs with targeting moieties or ligands. As a targeted therapy, SMDC has relatively few adverse reactions. SMDCs are usually constructed from three modules: a targeting ligand, a linker, and a drug payload.

Advantages of SMDC

SMDC is a rug conjugation strategy very similar to ADC. Compared to ADC, SMDC has its advantages:

  • SMDC drugs are composed of small molecules, the synthesis process and cost are easy to control, and the industrial operation is simple.
  • SMDC theoretically will not be immunogenic, and safety control is easier to implement.
  • The lower molecular weight of SMDC enables better cell permeability and better in vitro and in vivo stability in solid tumors.

SMDC for Rare Diseases

Drug conjugation is a commonly used strategy in drug discovery and rare disease therapies. SMDC plays an important role in the treatment of rare diseases due to its unique advantages such as low cost and simple operation. Currently, some SMDC targets have been used in the research of rare diseases:

  • Folate receptor (FR) for malignant mesothelioma
  • Prostate-specific membrane antigen (PSMA) for prostate cancer
  • Somatostatin receptor (SSTR) for conn's syndrome

Our Services

Targeting Ligand Screening

Our company can accelerate the screening of targeting ligands by taking into account factors such as binding affinity, target selectivity and conjugate size.

Linker Design and Synthesis

Providing expert communication to design linkers to optimize drug release, pharmacokinetic and pharmacodynamic properties, and the function of the targeting ligand or payload.

Targeting Ligand Screening

Our talented scientists provide customers with small molecule payload development services considering factors such as toxicity, release efficiency, multi-drug interactions and binding affinity.
