Chemical-genetic approaches offer the potential for unbiased functional annotation of chemical libraries. Mutations can alter the response of cells to a compound, revealing chemical-genetic interactions that can elucidate a compound’s mode of action. We developed a highly parallel and unbiased yeast chemical-genetic screening system involving three key components. First, in a drug-sensitive genetic background, we constructed an optimized, diagnostic mutant collection that is predictive for all major yeast biological processes. Second, we implemented a multiplexed (768-plex) barcode sequencing protocol, enabling assembly of thousands of chemical-genetic profiles. Finally, based on comparison of the chemical-genetic profiles with a compendium of genome-wide genetic interaction profiles, we predicted compound functionality. Applying this high-throughput approach, we screened 7 different compound libraries and annotated their functional diversity. We further validated biological process predictions, prioritized a diverse set of compounds, and identified compounds that appear to have dual modes of action.

The UN's Sustainable Development Goals (SDGs) and pledge to leave no one behind have raised the importance of ensuring equitable health outcomes and healthcare delivery. Multisectoral approaches to tackling neglected tropical diseases (NTDs), including prevention, diagnosis, treatment, and healthcare, have had a limited focus on gender. Yet, gender roles and relations shape vulnerability to NTDs, access to prevention and treatment, and experience of living with NTDs [1]. Understanding the similarities and differences of disease vulnerability and experience between genders can support NTD actors to deliver equitable prevention, diagnosis, and treatment services. The NTD community, including researchers and practitioners, needs to better understand these dynamics and take action to advance gender equality, meet the NTD roadmap 2020 goals, and contribute towards the SDGs and universal health coverage (UHC). The UHC movement is advocating for clear action to address the gender determinants of health. This viewpoint synthesizes evidence from a discussion paper [2] developed by the UN Development Programme (UNDP) and TDR (Special Programme for Research and Training in Tropical Diseases sponsored by UNICEF, UNDP, World Bank, and WHO) in partnership with the Liverpool School of Tropical Medicine to support governments and nongovernment organizations to understand how to recognize and address gender inequities within NTD programs and improve delivery through gender analysis. Gender refers to the socially constructed roles, behaviors, activities, attributes, and opportunities that any society considers appropriate for men and women, boys and girls, and people with nonbinary identities [3, 4]. Gender, sex, and their intersections with other social determinants of health shape peoples' vulnerability to and experience of multiple NTDs and their ability to access care and treatment [3, 5]. This can be complex and will vary between diseases, contexts, and other social and demographic factors such as age. Fig 1 highlights differences in disability-adjusted life years (DALYS) from different NTDs by age and sex from the Global Burden of Disease (GBD) Study [6]. By examining how gender shapes who is infected with NTDs, who accesses preventive medicines, who is diagnosed and treated, who is exposed or vulnerable to NTDs, and how and whose behavior is risk prone or risk averse, inequities can be better understood, challenged, and addressed.
