First of all, I would like to thank for the great opportunity to attend the Second A3 Roundtable Meeting on Chemical Probe Research Hub held in Sendai, Japan, where I was able to make an oral presentation in English from November 20^th to November 22^nd in 2019. Since it was first time for me to present in English, I was a little nervous before this meeting. Looking back on the 3 days now, it was very exciting and marvelous experience for me.

　In my oral presentation (10 min), the topic is the development of a tool molecule for elucidating the pathological mechanism of host-selective toxin. We focused on the chemical structure of host-selective toxins, we made and reported chemical probes for elucidating the mode-of-action. Some researchers were interested in identification of the target proteins mentioned in the future plan, I enjoyed the fruitful discussion in the question-and-answer session.
　In other oral sessions, many professors presented impressive “front-line” research involving chemical biology. These talks gave me some hints for my research, such as strategies for target identification etc. and motivated me.
　Through this meeting, these experiences made me inspired in my research. I’m looking forward to the day we will discuss again at another conference.
　At last, I’m deeply grateful to all organizers and all members in this meeting. I will value relationships with people gaining acquaintances in this meeting.
