The update of this English homepage is not as frequent as that of Japanese one. For the latest information, please kindly use Google translate (https://translate.google.com/) and just enter this URL (http://tkl.pc.uec.ac.jp/).　Our goal is to reduce drugs. To reduce the amount/frequency/dose, we are inventing fundamental technologies on targeted drugs, such as developing covalent biologics. Also, we aim to educate students by doing such tough researches that meet the quality of world-wide standards. We strongly promote lab members to take their own risks to conquer the very first findings which have never ever attained.

A commentary article written by Mr. Matsuzuka (M1) has been published in Peptide Newsletter Japan, The Japanese Peptide Society, No. 132, April 2024, pp. 4-6.
Title: Covalent Conjugation of Peptide Drugs and Acquisition of Blood Stability
Koki Matsuzuka, Riku Katsuki, Masaki Taki
（We thank Dr. Keitaro Suyama (Kyushu Univ.) for giving us the opportunity to write this paper at the best timing (mainly in terms of Matsuzuka's development) and the editorial board members of the Japanese Peptide Society for reviewing our manuscript.

Mr. Matsuzuka (M1) gave a poster presentation at the International Conference on Biofunctional Chemistry (@Nagoya Univ.). We thank all the people who visited our poster.
Title: COMPLEMENTING STABILITY AND AFFINITY OF A LINEAR PEPTIDIC BINDER BY ADAPTING RETRO-INVERSO TO A PEPTIDIC COVALENT BINDER
Koki Matsuzuka, Riku Katsuki, Masumi Taki
Poster short talks (one-minute slide presentations in English) were also very creative and had a strong presence. After the conference, he said, “It was good that I could participate in the conference with a perspective that I did not have before, such as looking for ideas that could be used in other people's research. Taki also participated as a member of the program organizing committee. I had a chance to talk with Dr. Peng Zou of Peking University and others at the eve of the event, which gave me a lot of insights. I would like to express my sincere gratitude to Dr. Asanuma, Dr. Tsukiji, Dr. Ojita, Dr. Sandong, and all the people involved for providing such a valuable opportunity.

Targeted Covalent Inhibitors (TCIs), such as aspirin (Bufferin), have a long history of more than 120 years, and most of them are small molecules. We have focused on biomolecular targeted covalent inhibitors (bioTCIs), which are more molecular-specifically targeted than small-molecular TCIs. We have specialized in "middle-sized bioTCIs" (midTCIs), which are particularly easy to produce. We have achieved:
(1) Combinatorial screening of peptide-type TCIs
(2) Transformation of DNA aptamers into TCIs
We have published a review of the historical background and the latest trends of bioTCI, including the above as an open access article.
