Prior to delivering a workshop at the University of São Paolo (USP) Ribeirão Preto campus, UK Network members Patrick Steel, Paul Denny, Ehmke Pohl and colleagues from USP and Durham University, spent a day exploring. The Serra da Canastra national park in Minas Gerais, the origin of the São Francisco river, is home to a tropical and scrubby forest, known to these scientists as USP professor Noberto Lopes’ “chemical hunting ground”. The workshop, “Development and evaluation of bioactive compounds” (March 25th-29th 2019; funded by Brazil’s Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) ‘SPRINT’ initiative), equipped ~40 Brazilian postgraduate students with skills to source novel chemicals from plants, fungi and animals. USP’s natural products library already holds many naturally-sourced compounds new to science, but more are needed – as leads for new medicines to treat the Neglected Tropical Diseases (NTDs) affecting Brazil and other developing countries. On this hot day, the team veer off a well-trodden path to go exploring in the forest, taking in spectacular waterfalls and an impromptu swim.
