Parthenolide is a natural product that exhibits anti-leukaemic activity, however, its clinical use is limited by its poor bioavailability. It may be extracted from feverfew and protocols for growing, extracting and derivatising it are reported. A novel parthenolide derivative with good bioavailability and pharmacological properties was identified through a screening cascade based on in vitro anti-leukaemic activity and calculated "drug-likeness" properties, in vitro and in vivo pharmacokinetics studies and hERG liability testing. In vitro studies showed the most promising derivative to have comparable anti-leukaemic activity to DMAPT, a previously described parthenolide derivative. The newly identified compound was shown to have pro-oxidant activity and in silico molecular docking studies indicate a prodrug mode of action. A synthesis scheme is presented for the production of amine 7 used in the generation of 5f.

The application of Reformatsky and Blaise reactions for the preparation of a diverse set of valuable intermediates and heterocycles in a one-pot protocol is described. To achieve this goal, a greener activation protocol for zinc in flow conditions has been developed to introduce this metal efficiently into α-bromoacetates. The organozinc compounds were added to a diverse set of ketones and nitriles to obtain a wide range of functional groups and heterocyclic systems.

Transient receptor potential canonical 3/6/7 (TRPC3/6/7) are highly homologous receptor-operated nonselective cation channels. Despite their physiological significance, very few selective and potent agonists are available for functional examination of these channels. Using a cell-based high throughput screening approach, a lead compound with the pyrazolopyrimidine skeleton was identified as a TRPC6 agonist. Synthetic schemes for the lead and its analogues were established, and structural-activity relationship studies were carried out. A series of potent and direct agonists of TRPC3/6/7 channels were identified, and among them, 4m-4p have a potency order of TRPC3 > C7 > C6, with 4n being the most potent with an EC50 of 20 nM on TRPC3. Importantly, these compounds exhibited no stimulatory activity on related TRP channels. The potent and selective compounds described here should be suitable for evaluation of the roles of TRPC channels in the physiology and pathogenesis of diseases, including glomerulosclerosis and cancer.
