    Bachem enters exclusive licensing agreement with Jitsubo for Molecular Hiving™ technology

    Bubendorf, Switzerland: –Peptide technology specialist Bachem AG has signed an exclusive Licensing Agreement with Japan’s Jitsubo Co. Ltd for its Molecular Hiving™ technology for tag-assisted liquid-phase peptide synthesis technology.

    Under the License Agreement, Jitsubo will develop selected manufacturing processes using Molecular Hiving™ that it will transfer to Bachem for further optimization, scale up and production for commercial applications, in return for development fees and royalties.

    Molecular Hiving™ advantages

    Molecular Hiving™, developed by Professor Kazuhiro Chiba at Tokyo University of Technology and Agriculture, uses a hydrophobic tag, a simple chemical structure but having variable function by introducing variable function groups into an aromatic ring (see Image). Tags can be removed by global deprotection condition after elongation is complete.

    Tagging acts in an equivalent way to the resin in solid-phase peptide synthesis but with added advantages that the intermediates can be solved and the reaction mixture is homogeneous. The technology supports immediate scaling up and the one-pot procedure needs only one reactor for the elongation process.

    Bachem expects to use the Molecular Hiving™ technology to reduce manufacturing costs, improve sustainability with greener chemistry, achieve more efficient scale up, and enhance in-process controls.

    Collaborative relationship

    The two companies had already established a close collaboration, with several joint projects for active pharmaceutical ingredients (APIs) as well as cosmetic peptides, have already been initiated and successfully realized using Jitsubo’s technology at Bachem.

    Dr. Günther Loidl, Chief Technology Officer of Bachem Holding AG, said: “We are convinced that Jitsubo’s Molecular Hiving™ technology offers substantial advantages regarding efficiency, and towards greener manufacturing. It complements Bachem’s current extensive technology base and is a great fit for us because Bachem is already offering unique capabilities in the area of solid phase, hybrid, and solution phase peptide chemistry. We are excited to be the only contract manufacturing organization to offer this innovative technology to our customers.”

    Jitsubo CEO Dr. Kazuaki Kanai commented: “It is a great pleasure for us having collaborated with the industry leader, Bachem, in exploring applications of our unique technology, Molecular Hiving™, and now having reached an exclusive License Agreement, which will provide opportunities to deliver products to customers much faster and at greater scale. We will continue our development efforts broadening the technology base to meet various requirements from the society and hope to deliver meaningful products to customers through this collaboration and more importantly, to the world’s patients, realizing our vision to “Enrich the world with smiles”.

    Bachem enters exclusive licensing agreement with Jitsubo for Molecular Hiving™ technology

    Molecular Hiving™ technology uses a hydrophobic tag to introduce variable function groups into an aromatic ring, such as hydrophobic benzyl alcohol and amine as illustrated here. When target peptide has carboxylate at C-terminus, the tag is 1, and amide, the tag is 2. Both tags can be removed by global deprotection after the completion of elongation
