Wheate, Nial - University of Sydney

研究领域

Dr Wheate's research interests are primarily into pharmaceutically related fields: platinum-based cancer drugs, and drug delivery and formulation. Platinum drugs for the treatment of cancer Cisplatin was the first platinum drug approved for human use, and since its discovery, platinum-based drugs are listed in more than 50% of all chemotherapy regimens. In his work, Dr Wheate examines the DNA binding of platinum drugs, as well the design and synthesis of new drugs. Recently, he has been exploring new drug designs that incorporate the structural features of picoplatin and triplatininto a single drug. Drug delivery for cancer Many cancer drugs can be improved by better targeting them to solid cancers. To this effect, Dr Wheate has examined a range of delivery scaffolds for platinum drugs including: dendrimers, gold and iron oxide nanoparticles, aptamers and macrocycles, including cyclodextrins and calixarenes. Cucurbiturils One particular drug delivery scaffold of interest to Dr Wheate is the family of macrocycles called cucurbiturils. Dr Wheate was the first to show their application as delivery vehicles and has since shown how they can be used to improve drug solubility, drug stability in the solid and solution states, overcome drug resistance, their safety and their use in biodiagnostics. He is also the leading expert in the pharmaceutical formulation of cucurbiturils having designed oral tablet, eye and topical cream dosage forms.
