Peptide Lead Optimization

The inhibition of PARP has emerged as a promising therapeutic strategy, particularly in cancer treatment, where tumors with homologous recombination deficiencies (such as BRCA1/2 mutations) exhibit heightened sensitivity to PARP inhibitors. Alfa Cytology provides peptide lead optimization services for development PARP peptide inhibitor to combat various diseases.

Introduction to Peptide Lead Optimization

Peptide lead optimization represents a vital approach in developing potent PARP inhibitors, enhancing their efficacy and selectivity while improving pharmacokinetic properties. The optimization process involves modifying peptide sequences to enhance their binding affinity to PARP enzymes. By tailoring peptide structures, it is possible to create candidates that effectively disrupt PARP activity, thereby promoting cancer cell death and increasing the effectiveness of concurrent therapies, such as chemotherapy and radiation.
