Collaborations Pharmaceuticals Announces Publication of New HIV Reverse Transcriptase inhibitors to address HAND

RALEIGH, NC, USA, May 2, 2023/EINPresswire.com/ -- Collaborations Pharmaceuticals, Inc. (CPI) with collaborators at the Research Center of Biotechnology RAS, Moscow (Dr. Vadim Makarov); the University of North Carolina, Chapel Hill (Dr. Julie Nelson); as well as collaborators at the University of Cagliari are pleased to announce their NIH/NINDS funded work resulting in new peer reviewed publication entitled "N-phenyl-1-(phenylsulfonyl)-1H-1,2,4-triazol-3-amine as a new class of Human immunodeficiency virus (HIV) non-nucleoside reverse transcriptase inhibitors (NNRTI)."

HIV infection is one of the most important pathogens affecting mankind. There were approximately 1.5 million new cases in 2021 and 38.4 million living with HIV, amongst them 2.73 million were children. The disease can be managed with a cocktail of antiretroviral drugs including NNRTI. It has been reported that there is resistance against NNRTIs as well as side effects such as HIV associated neurocognitive disorders (HAND), which results in symptoms from minor problems with memory to severe dementia-like symptoms. We therefore need to have more diversity in the types of chemical structures assessed, in order to stand the best chance of addressing both drug resistance and HAND in future.

“We have identified the N-phenyl-1-(phenylsulfonyl)-1H-1,2,4-triazol-3-amine scaffold as possessing potent activity as an NNRTI. In the process we have developed over 100 analogs using a classical medicinal chemistry structure activity relationship (SAR) to optimize activity against wild-type, A17 mutant (K103N/Y181C) as well as other common mutant strains resistant to approved NNRTIs. This has led to the discovery of a series of optimized compounds with picomolar activity against wild-type HIV that retain activity against these clinically relevant mutants” said CPI CEO Dr. Sean Ekins.

“HIV remains a global threat and as such the need for additional treatments remains of utmost importance. Current therapies have yet to eradicate the prevalence of HAND; therefore, this still represents an important therapeutic goal that we have addressed. These molecules are a new class of HIV NNRTI and without likely toxicity seen with older drugs. We also look forward to partnering these molecules from our pipeline with other companies to further develop this molecule.”
