- Landmark paper on dual HIF-1 and HIF-2 inhibitor that works by inhibiting the interaction of both HIF-1a and HIF-2a with HIF-1ß
SOUTHAMPTON, England, March 26, 2024 /PRNewswire/ -- Curve Therapeutics ("Curve" or the "Company"), a private biotechnology company pioneering a revolutionary intracellular screening platform addressing complex and challenging disease targets, today announces the publication of an article in the Journal of the American Chemical Society (JACS). The paper entitled 'Identification and Development of Cyclic Peptide Inhibitors of Hypoxia Inducible Factors (HIF) 1 and 2 That Disrupt Hypoxia-Related Signalling in Cancer Cells' can be viewed here.1 Curve's Chief Scientific Officer, Professor Ali Tavassoli, co-authored the article and leads the academic group at the University of Southampton where the work was undertaken.
Professor Ali Tavassoli, Chief Scientific Officer of Curve Therapeutics, said: "It is well recognised that HIF plays a key role in the survival and growth of solid tumours. The compounds we report in this paper inhibit the protein-protein interaction of the two subunits that form the HIF transcription factor. We show that these compounds prevent the hypoxia-induced activity of this transcription factor, stopping hypoxia-response in cell-based assays. This paper underlines the promising therapeutic potential of dual HIF inhibition as an approach for the treatment of a variety of cancers."
Curve Therapeutics is a leader in the discovery of innovative therapeutics to address disease targets which are difficult to target using conventional drug discovery methods. Through the utilisation of its world leading Microcyle® discovery platform, Curve can screen directly inside mammalian cells, allowing for the identification of biologically active library members within an intracellular environment where both the library and the target are present in their native conformations. Curve is developing a non-peptidic, small-molecule dual inhibitor of HIF-1 and HIF-2 with first-in-class potential.
This is the first report of a dual HIF-1 and HIF-2 inhibitor which functions by inhibiting the interaction of both HIF-1a and HIF-2a with HIF-1ß. The Microcycles discovered by Prof. Tavassoli were identified using his SICLOPPS screening platform and show good cellular activity. Patents and patent applications describing these HIF inhibitory Microcycles are exclusively licensed to Curve.
About Curve Therapeutics
Curve Therapeutics is a private biotechnology company pioneering a revolutionary intracellular screening platform to enable the discovery of innovative therapeutics that address complex and challenging disease targets with the potential to transform the lives of patients. Curve originated from world-leading Microcycle® research conducted by Professor Tavassoli's group in the Department of Chemistry at the University of Southampton, UK. Curve is backed by blue chip investors including Advent Life Sciences, Epidarex Capital, Pfizer Ventures, Columbus Venture Partners and British Patient Capital. Curve has a US$1.7bn global research collaboration with MSD the trade name of Merck & Co., Inc., Kenilworth, NJ USA, to discover and validate modulators of up to five therapeutic targets using its Microcycle® technology, initially for oncology and neurology indications.

About Curve's Microcycle® platform
Curve has developed an IP-protected, mammalian cell platform technology for functional screening and enrichment of diverse hexameric cyclic peptide Microcycle® libraries to identify those library members that have the desired biological activity against a therapeutic target. Curve's platform allows direct screening for biologically active library members inside mammalian cells and facilitates small molecule hit-to-lead programmes. A key advantage of the technology is that both the library and the target are present in all of their native conformations within a cell. Uniquely, the compact size and rigid structure of Microcycles® enables the design of non-peptide small molecule leads. The platform can be used for a wide range of therapeutically relevant targets, including protein-protein and protein-DNA interactions and has been used by Curve to develop a pipeline of cancer programmes against targets including a dual HIF-1/HIF-2 inhibitor and an inhibitor of ATIC homodimerization.
