Synthesis of Lanthanide(III) Chelates by Using 'Click' Chemistry.
Research in the Rivas Laboratory focuses on the field of natural product synthesis with an emphasis on the development of catalytic asymmetric methods that facilitate the construction of complex molecules of promising pediatric therapeutic value. Lead discovery for the treatment of pediatric malignancies, particularly glucocorticoid resistant acute lymphoblastic leukemia (ALL) are amongst our priorities. We narrow on strategic bond disconnections promoted enzymatically in nature, which remain inaccessible enantioselectively using modern synthetic methodologies. Current areas of research in the Rivas laboratory include total synthesis of sesquiterpenoids, alkaloids, and the development of catalytic systems for enantioselective electrophilic halogenation. In parallel, our laboratory has an ongoing research program in the area of bioactive-guided terrestrial natural product isolation and chemical structure elucidation. Our research integrates the critical areas of synthetic method development, total synthesis and medicinal chemistry.

Design and Synthesis of Triazole-Based Peptide Dendrimers.
Terrestrial plants are capable of producing an overwhelming variety of secondary metabolites among others sesquiterpenoids, both in terms of complexity and quantity. Sesquiterpenoids allow plants to cope with various types of stress, and often have important biological activities in humans. Many of these compounds show anti-cancer activities, or serve as specific enzyme modulators. The Rivas laboratory is working on developing strategies towards construction of spiro-quaternary carbon centers found in acorane sesquiterpenoids. Synthesis of quaternary centers in a stereochemical and asymmetric controlled manner remain a challenge in the field of organic chemistry. New asymmetric methodologies are needed to facilitate the large scale synthesis of these compounds to derivatize and evaluate their biological properties. Colletoic Acid is a novel acorane sesquiterpenoid isolated from the fungus colletrotrichum gleosporioides. It was reported by Takatsu, T. to exert remarkable selective inhibition against 11-� Hydroxysteroid dehydrogenase 1 (11-�HSD1) with an IC50 of 13nM. This biological profile renders colletoic acid a potential molecular probe to elucidate important biological mechanisms mediated by 11-� Hydroxysteroid dehydrogenase type 1 action in cancer metabolism. In a campaign to develop asymmetric synthetic strategies to this family of natural products, we have developed an efficient synthetic route to afford multigram quantities of the core of this novel scaffold that will allow us to develop analogs and establish their structure-activity relationships (SAR).
