Computer-aided drug design (CADD) has penetrated into all aspects of drug discovery, and with the in-depth application of artificial intelligence and cloud computing, it is foreseeable that CADD will play a greater role in drug discovery projects in the future, improving efficiency and further reducing high costs of drug development. Creative Biostructure 's CADD and virtual screening platform is a comprehensive platform for new drug discovery that integrates a variety of computer applications. It can be utilized for early preclinical research of small molecule drugs, peptides, antibodies, and therapeutic proteins.
