News of Note

Research Grants Awarded



Dr. Debopam Chakrabarti received an NIH R01 grant for his project entitled, NOVEL ANTIMALARIALS FROM FUNGI.






Publication and Research Highlights

Dr. Chakrabarti’s research group reports the discovery of fast-acting curative aryvinylquinoline antimalarial compounds in a recent article in the Journal of Medicinal Chemistry.





Dr. Debopam Chakrabarti and his collaborator’s publication is on the cover of February Issue of ACS Infectious Diseases. This cover shows a novel antiplasmodial agent attacking malaria parasites in infected red blood cells. This new compound was re-engineered from the indole alkaloid yohimbine using a ring distortion chemical synthesis reported by Huigens, Chakrabarti and co-workers”.

Dr. Sean Moore’s research group reported the mechanistic insight of translational frameshifting as a result of ribosomes colliding in the Proceedings of the National Academy of Sciences. The figure shows that stalled ribosomes have higher E-site occupancy in the absence of ribosomal protein bL9.

Dr. Saleh Naser’s research has been highlighted on the cover of December 2019 issue of Microorganisms. The study clearly associated Mycobacterium avium subspecies paratuberculosis with osteoporosis in autoimmune disease patients, including rheumatoid arthritis, with key SNPs in the TNF receptor superfamily gene.

Student Accomplishments

Michelle Cherne successfully defended her PhD. dissertation work (Dr. Alex Cole, supervisor) entitled “ HIV Infection in Women: Novel Approaches for Prevention”. Congrats to Dr. Cherne!
