Problems that can be solved

Are you facing challenges inPROTAC drug development? We've got you covered.

  • Route Scouting

    We can solve issues such as the need for milder reaction conditions to tolerate more complex functional groups, the problem of longer reaction steps, the low-yield dilemma, and situations involving high impurity levels.

  • Metal / Chiral Synthesis

    We are here to help you overcome the high cost of metal catalysts like Pd/Ir, the obstacles in large-scale production, racemization caused by complex conditions, and the difficulties in click chemistry for linkers using azide reagents.

  • Crystallization / Drug Product

    We can solve problems such as the presence of more amorphous intermediates or APIs due to PEG linkers, the challenge of developing an effective recrystallization process, and issues related to poor solubility.

Our Advantages

We've got all-round advantages spanning every stage of PROTAC drug development, from pre-clinical to commercialization, covering intermediates, drug substance (DS), and drug product (DP), all in accordance with international standards.

  • Global Network Solutions

    R&D centers and production sites across the US, Europe, and China, meeting customers' demand with geographical solutions and cost-efficiency.
