Abstract: GPR55 is a potential target for treating various illnesses. Inhibition of this membrane-bound G protein-coupled receptor may potentially alleviate inflammatory and neuropathic pain and treat osteoporosis and cancer. Radiolabelling of a potent and selective ligand will aid in establishing the physiological roles and pharmacology of the receptor. High throughput screening presented a hit that was used to design, based on a constructed homology model, and synthesize various analogues. The structure activity relationships inferred from the tested analogues will help in refinement of the homology model and design future analogues. (5Z)-7-Oxozeanol and related analogues were isolated and screened to explore their activity as TAK-1 inhibitors. Seven analogues were synthesized and eight natural products isolated that examined the role that different areas of the molecule contribute to TAK-1 inhibition. A novel nonaromatic difluoro-derivative was synthesized that had similar potency compared to the lead. This is the first example of a nonaromatic compound in this class to have TAK-1 inhibition. Covalent docking for the isolated and synthesized analogues was carried out and found a strong correlation between the observed activities and the calculated binding.
