Development of the aza-Prins reaction; synthesis and biological evaluation of JBIR-102

Objective

Human malignant pleural mesothelioma is an aggressive (fatal) lung cancer which is always associated with previous asbestos exposure. Typically symptoms do not appear until 35-40 years after the original exposure, with life expectancy then 12-18 months. Given the great use of asbestos during the 20th century and this long latency period, it is no surprise that cases of mesothelioma continue to rise. There is no known cure for mesothelioma: traditional chemotherapeutic treatments have had little impact on the disease and radiotherapy or partial pleurectomy have only very limited impact on life expectancy. However, very little in the way of mesothelioma research is taking place, as it is frequently not considered to be a ‘big enough market’ (<1% of all cancers in the U.K. approx. 2300 deaths per annum) and consequently there are currently no drugs in development for this disease. A second reason for this is that there have been no reported good lead compounds (natural products) as a starting point for the drug discovery process. Until now.
There are now a very small number of natural products which demonstrate activity against mesothelioma. First reported in 2012, and isolated from Saccharopolyspora sp. RL78, the natural product termed JBIR-102 possesses a unique structural architecture, and is only the third natural product to be isolated to exhibit activity against human malignant pleural mesothelioma.
The aza-silyl-Prins reaction has been developed within our research group as a rapid method to prepare aza-bicycles – structural architectures found in many alkaloids and natural products, and crucially at the centre of JBIR-102. The aim of the project, therefore, is to optimise the aza-silyl-Prins reaction and then investigate its application in the synthesis of JBIR-102. A collaboration with a specialist cancer biology group will see all the compounds prepared evaluated against mesothelioma cell lines. This will be the first study of this kind.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.

MSCA-IF-EF-ST - Standard EF

Net EU contribution

Net EU financial contribution. The sum of money that the participant receives, deducted by the EU contribution to its linked third party. It considers the distribution of the EU financial contribution between direct beneficiaries of the project and other types of participants, like third-party participants.
