August 2025 - Publication Updates
Our group, in collaboration with colleagues at the University of Sydney, recently published a Perspective in the Journal of Medicinal Chemistry highlighting current non-opioid strategies for the treatment of neuropathic pain. This work aligns closely with our ongoing efforts in the GlyT2 inhibitor field, and we look forward to sharing additional publications on our GlyT2 program in the near future. The Perspective can be accessed at the link below:

Congratulations to Darian Topolski! Darian obtained her Master's degree this spring.
April 2025 - Publication Update
Our group is collaborating with Robert Vandenberg and his team at the University of Sydney, as well as Azadeh Shahzavar and her colleagues at the University of Copenhagen, to develop novel GlyT2 inhibitors as potential therapeutics for neuropathic pain. GlyT2 inhibitors represent a promising non-opioid strategy that enhances inhibitory neurotransmission at the spinal level. Recently, Dr. Shahzavar’s team resolved the cryo-EM structure of GlyT2 in complex with our novel tool compound, RPI-GLYT2-82. This structural insight is providing a foundation for rational design efforts and has enabled the discovery of new analogue series with significant potential for lead optimization and further development. A preprint of this work is available here:

October 2024 - Rensselaer Researcher Seeks New Treatment For Blindness-Causing Diseases
Rensselaer Polytechnic Institute’s Christopher Cioffi, Ph.D., Thomas and Constance D'Ambra Professor in Organic Chemistry, has been collaborating with Konstantin Petrukhin, Ph.D., Professor of Ophthalmic Science at Columbia University, to develop compounds to treat dry age-related macular degeneration (AMD) and Stargardt disease — both blindness-causing diseases.
The team’s work has led to the discovery of an advanced preclinical candidate. Now, Cioffi and Petrukhin have received a $6.4 million grant over five years from the National Institutes of Health’s National Eye Institute to conduct drug development work and investigational new drug (IND)-enabling toxicology studies.
“This award helps us get one step closer to bringing our advanced compound into the clinic,” said Cioffi. “We will assess its ability to slow down disease progression and help preserve vision for Stargardt disease and dry AMD patients.”

May 2023 - Rensselaer Researcher To Develop Drug for Rare Childhood Disease That Leads to Blindness
$2.5 million grant from NIH to fund design of new treatment for Stargardt disease
Rensselaer Polytechnic Institute’s Christopher Cioffi, Thomas and Constance D’Ambra Professor in Organic Chemistry, has received a $2.5 million grant from the National Institutes of Health, along with Konstantin Petrukhin of Columbia University and Gennadiy Moiseyev of Wake Forest University. The grant will enable the team to design a drug to treat Stargardt disease, a rare retinal disorder.
Stargardt disease affects approximately 30,000 people in the United States and is often diagnosed in childhood or adolescence. It is a rare form of inherited macular dystrophy associated with mutations in the ABCA4 gene, which is a transporter that plays a critical role in clearing retinoids from the photoreceptors. When it is mutated, visual cycle byproducts called bisretinoids build up quickly and cause damage to retinal tissue.
Currently, there are no treatments available for the disease. “Our goal is to develop an oral drug that reduces the excessive buildup of bisretinoids in the retina that is associated with Stargardt disease,” said Cioffi. “We will target RPE65, which is the rate-limiting enzyme of the visual cycle, to accomplish this. We hope to slow or even halt the progression of Stargardt disease and preserve central vision for these patients.”

June 2022 - Rensselaer Researchers Receive $3.5 Million Grant for Development of COVID Antiviral Drug
Goal is to produce a low-dose, oral medication that can be taken at home
Rensselaer Polytechnic Institute researchers Gaetano Montelione and Christopher Cioffi will use a five-year, $3.5 million grant from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), to develop a low-dose, oral COVID antiviral drug that can be administered at home. Dr. Montelione is the Constellation Endowed Chair of Structural Bioinformatics and Dr. Cioffi is the Thomas and Constance D’Ambra Endowed Chair of Organic Chemistry. Both are professors in the Department of Chemistry and Chemical Biology.
Rensselaer’s research is part of the consortium of a new antiviral drug development center, called the Center for Antiviral Medicines and Pandemic Preparedness (CAMPP), that will be led by Scripps Research. The center will be one of nine NIAID-sponsored Antiviral Drug Discovery (AViDD) Centers for Pathogens of Pandemic Concern.
