TNF Receptor Associated Protein 1 (TRAP1) is a mitochondrial paralog of Hsp90 related to the promotion of tumorigenesis in various cancers via maintaining mitochondrial integrity, reducing the production of reactive oxygen species, and reprogramming cellular metabolism. Consequently, Hsp90 and TRAP1 have been targeted to develop cancer therapeutics. Herein, we report a series of pyrazolo[3,4-d]pyrimidine derivatives that are mitochondria-permeable TRAP1 inhibitors. Structure-based drug design guided the optimization of potency, leading to the identification of compounds 47 and 48 as potent TRAP1 and Hsp90 inhibitors with good metabolic and plasma stability as well as acceptable CYP and hERG inhibition. X-ray co-crystallization studies confirmed both 47 and 48 interact with the ATP binding pocket in the TRAP1 protein. Compounds 47 and 48 demonstrated excellent anticancer efficiency in various cancer cells, with limited toxicity over normal hepatocyte and prostate cells. Mouse PC3 xenograft studies showed 47 and 48 significantly reduced tumor growth.

Antagonism of the adenosine A2A receptor on T cells blocks the hypoxia-adenosinergic pathway to promote tumor rejection. Using an in vivo immunoassay based on the Concanavalin A mouse model, a series of A2A antagonists were studied and identified preladenant as a potent lead compound for development.Molecular modeling was employed to assist drug design and subsequent synthesis of analogs and those of tozadenant, including fluorinated polyethylene glycol PEGylated derivatives. The efficacy of the analogs was evaluated using two in vitro functional bioassays, and compound 29, a fluorinated triethylene glycol derivative of preladenant, was confirmed as a potential immunotherapeutic agent.
