Varying the metal to ethacrynic acid ratio in ruthenium(ii)/osmium(ii)-p-cymene conjugates

Paul Joseph Dyson, Catherine Marie Amélie Clavel, Mylène Soudani, Emilia Paunescu

Following the identification of a ruthenium(II)-arene complex with an ethacrynic acid-modified imidazole ligand, which inhibits glutathione transferase (GST) and is cytotoxic to chemo-resistant cancer cells, a series of structurally related ruthenium(II)- ...

Anti-angiogenic properties of chlorambucil derivatives with fluorous and hydrocarbon appendages

Paul Joseph Dyson, Patrycja Nowak-Sliwinska, Catherine Marie Amélie Clavel, Emilia Paunescu

Chlorambucil (CLB) derivatives with long fluorous (referred to as 1 and 2) or hydrocarbon (3) chains have been evaluated in a series of in vitro and in vivo assays. In cell viability inhibition assays, both derivatives 2 and 3 show selective cytotoxicity t ...

Improved Angiostatic Activity of Dasatinib by Modulation with Hydrophobic Chains

Paul Joseph Dyson, Patrycja Nowak-Sliwinska, Catherine Marie Amélie Clavel, Emilia Paunescu

Dasatinib is an orally active nonselective tyrosine kinase inhibitor used to treat certain types of adult leukemia. By inhibiting PDGFR-beta and SFKs in both tumor cells and tumor associated endothelial cells, dasatinib inhibits tumor growth and angiogenes ...

In vivo evaluation of small-molecule thermoresponsive anticancer drugs potentiated by hyperthermia

Paul Joseph Dyson, Patrycja Nowak-Sliwinska, Catherine Marie Amélie Clavel, Emilia Paunescu

Hyperthermia used as an adjuvant with chemotherapy is highly promising in the treatment of certain cancers. Currently, the small molecule drugs used in combination with hyperthermia were not designed for this application. Herein, we report the evaluation o ...

Thermoresponsive fluorinated small-molecule drugs: a new concept for efficient localized chemotherapy

Paul Joseph Dyson, Patrycja Nowak-Sliwinska, Catherine Marie Amélie Clavel, Emilia Paunescu

Hyperthermia is currently being explored as an adjuvant treatment to conventional therapies with chemotherapeutic agents based on thermoresponsive macromolecules. Although the concept of hyperthermia has existed for many years it has yet to become routinel ...
