Webinar On Foldamers: From Structure to Function and Renewable nano-sized triterpenoids: Self-assembly, properties & application.



Baridua, 9th Mile, Meghalaya, 21st May 2021: An international webinar was organized by the Department of Chemistry, University of Science & Technology Meghalaya (USTM), on 21st May via the online platform at 1:30 p.m. Prof. Gaetano Angelici from the University of Pisa, Italy and Dr. RakhiMazumder, Post-doctoral fellow at Mahidol University, Thailand were the invited speakers of this webinar. The first talk by Prof. Gaetano Angelici was entitled as “Foldamers: From Structure to Function” and the second talk by Dr. RakhiMazumder was on ‘‘Renewable nano-sized triterpenoids: Self-assembly, properties & application.’’

A total of around 125 people were participated in the webinar through the zoom app and also on the Facebook live from the “USTM update” page. Faculties from different institutes like Saldiha College-West Bengal, St. Anthony’s College, Mangaldai College, Barpeta Polytechnic etc., and Research Scholars from the institutes like Gauhati University, IASST Guwahati, Handique Girls’ College, etc. have participated in the webinar. Also, the students (both PG & UG) and faculties from USTM have actively participated in the webinar.

The talks delivered by the invitees in the webinar are briefly highlighted below.

Prof. G. Angelici talked about foldamers which are artificial molecules that mimic the ability of biological molecules like proteins, nucleic acids and polysaccharides to fold into well-defined conformations. He discussed about two interesting amino acids proline and phenyl alanine including the stability of peptides when substituted into oxazolidine-2-one. He also added that the peptides can be designed in different length and they are highly stable in nature due to the intramolecular hydrogen bonding. The diphenylalanine peptide nanotubes synthesis, elongation of oligomers and their effects with different solvents are also discussed. Later, he concluded his lecture with an acknowledgment note to his students and co-workers. In the questionnaire section.

Dr. Mazumder introduced the importance of triterpenoids and also the Arjunolic acid which can be used as a potential drug carrier. She also threw light on the development of gel by the combination of arjunolic acid and T. Arjuna bark extract entrapped with palladium (Pd) nanoparticles. Composites of Na-arjunolate with graphene oxide, Mn (II) and Ca (II) were fabricated and characterized. The trihybrid gel has vesicular structure as identified from High Resolution Transmission Electron Microscopy (HRTEM) studies. The potentiality of the fabricated compounds was tested with the Doxyrubicin drug.

There was a question answer session after each talk which further assisted participants for clearing their doubts & understandings.

It is worthy to mention that more than ninety feedback forms were received with their positive comments&suggestions which gives immense inspiration to organize more such kind of event in near future.
