Advancing Women in Chemistry

Breaking the Gender Imbalance: Female Presence in the Computational Chemistry Group at Viva Biotech

The growing field of computational chemistry and artificial intelligence is drawing unprecedented attention in drug discovery. However, the underrepresentation of female scientists persists in the field. While the gender disparity is acknowledged in academic settings, the issue is less addressed and intensifies in the pharmaceutical and biotech industry both at the entry-level and leadership positions. At Viva Biotech, we challenge this norm: over 60% of the full-time employees in our computational chemistry group are women, a testament of our commitment to the pursuit of gender equality. We share our vision of the evolving role of computational chemistry in drug discovery and where women stand and rise in the field. In this article, we discuss how we engage female empowerment with tactical approaches and from personal experiences. The intention is to offer actionable guidance for female computational chemists at early career stages to bring visibility to their impacts, and ascent to senior positions.

The Impact of Interdisciplinary, Gender and Geographic Distributions on the Citation Patterns of the Journal of Chemical Information and Modeling

There has been a growing recognition of the need for diversity and inclusion in scientific fields. This trend is reflected in the Journal of Chemical Information and Modeling (JCIM), where there has been a gradual increase in the number of papers that embrace this diversity. In this viewpoint, we analyze the evolution of the profile of papers published in JCIM from 1996 to 2022 addressing three diversity criteria, namely interdisciplinarity, geographic and gender distributions, and their impact on citation patterns. We used natural language processing tools for the classification of main areas and gender, as well as metadata, to analyze a total of 7384 articles published in the categories of research articles, reviews, and brief reports. Our analyses reveal that the relative number of articles and citation patterns are similar across the main areas within the scope of JCIM, and international collaboration and publications encompassing two to three research areas attract more citations. The percentage of female authors has increased from 1996 (less than 20%) to 2022 (more than 32%), indicating a positive trend toward gender diversity in almost all geographic regions, although the percentage of publications by single female authors remains lower than 20%. Most JCIM citations come from Europe and the Americas, with a tendency for JCIM papers to cite articles from the same continent. Furthermore, there is a correlation between the gender of the authors, as JCIM manuscripts authored by females are more likely to be cited by other JCIM manuscripts authored by females.

Advancing Women in Chemistry: A Step Toward Gender Parity

As chemistry progressed over the years, modern society witnessed the significant contribution of women chemists. However, the persisting gender imbalance in the scientific community, attributed to improper societal norms and several other reasons, is a matter of concern. The manuscript highlights some great women chemists, such as Nobel Prize awardees, who have created history through their outstanding research work and are role models for other women. Since women continue to encounter recurring obstacles to moving forward in their area, the "leaky pipeline" of women in chemical science remains problematic. Numerous factors, including having to shoulder the labor of childcare and household work and a lack of awareness of regulations and possibilities, contribute to prejudices and the gender gap in higher-level administrative and decision-making roles. To close the gender gap and empower women chemists, we highlight some initiatives (awards, fellowships, schemes, and grants) that have been put forth by governments, organizations, foundations, companies, industries, and publishing societies. As per statistics, only 4% of female scientists have been awarded the Nobel Prize in chemistry until now. Only 35%, 22%, 14%, 26%, and 5% of women are serving as editors-in-chief, while 38%, 40%, 18%, 22%, and 21% are working as associate editors of the American Chemical Society (ACS), Royal Society of Chemistry (RSC), Wiley, Elsevier, and Springer journals, respectively. A further issue is that women receive far fewer honors in chemistry. To promote a more encouraging atmosphere for women scientists at all career phases, we listed some recommendations that research grant funders, academic institutions, publishers, and scientific organizations can follow. For gender parity, the paper sought to address the current situation of women in the chemical sciences. Women's contributions to chemistry will promote innovation and progress in the field.

The Impacts of the Molecular Education and Research Consortium in Undergraduate Computational Chemistry on the Careers of Women in Computational Chemistry

The Molecular Education and Research Consortium in Undergraduate Computational Chemistry (MERCURY) has supported a diverse group of faculty and students for over 20 years by providing computational resources as well as networking opportunities and professional support. The consortium comprises 38 faculty (42% women) at 34 different institutions, who have trained nearly 900 undergraduate students, more than two-thirds of whom identify as women and one-quarter identify as students of color. MERCURY provides a model for the support necessary for faculty to achieve professional advancement and career satisfaction. The range of experiences and expertise of the consortium members provides excellent networking opportunities that allow MERCURY faculty to support each other's teaching, research, and service needs, including generating meaningful scientific advancements and outcomes with undergraduate researchers as well as being leaders at the departmental, institutional, and national levels. While all MERCURY faculty benefit from these supports, the disproportionate number of women in the consortium, relative to their representation in computational sciences generally, produces a sizable impact on advancing women in the computational sciences. In this report, the women of MERCURY share how the consortium has benefited their careers and the careers of their students.

Interplay between the Enamine and Imine Forms of the Hydrolyzed Imipenem in the Active Sites of Metallo-β-lactamases and in Water Solution

Deactivation of the β-lactam antibiotics in the active sites of the β-lactamases is among the main mechanisms of bacterial antibiotic resistance. As drugs of last resort, carbapenems are efficiently hydrolyzed by metallo-β-lactamases, presenting a serious threat to human health. Our study reveals mechanistic aspects of the imipenem hydrolysis by bizinc metallo-β-lactamases, NDM-1 and L1, belonging to the B1 and the B3 subclasses, respectively. The results of QM(PBE0-D3/6-31G**)/MM simulations show that the enamine product with the protonated nitrogen atom is formed as the major product in NDM-1 and as the only product in the L1 active site. In NDM-1, there is also another reaction pathway that leads to the formation of the (S)-enantiomer of the imine form of the hydrolyzed imipenem; this process occurs with the higher energy barriers. The absence of the second pathway in L1 is due to the different amino acid composition of the active site loop. In L1, the hydrophobic Pro226 residue is located above the pyrroline ring of imipenem that blocks protonation of the carbon atom. Electron density analysis is performed at the stationary points to compare reaction pathways in L1 and NDM-1. Tautomerization from the enamine to the imine form likely happens in solution after the dissociation of the hydrolyzed imipenem from the active site of the enzyme. Classical molecular dynamics simulations of the hydrolyzed imipenem in solution, both with the neutral enamine and the negatively charged N-C₂-C₃ fragment, demonstrate a huge diversity of conformations. The vast majority of conformations blocks the C₃-atom from the side required for the (S)-imine formation upon tautomerization. Thus, according to our calculations, formation of the (R)-imine is more likely. QM(PBE0-D3/6-31G**)/MM molecular dynamics simulations of the hydrolyzed imipenem with the negatively charged N-C₂-C₃ fragment followed by the Laplacian bond order analysis demonstrate that the N═C₂-C₃^- resonance structure is the most pronounced that facilitates formation of the imine form. The proposed mechanism of the enzymatic enamine formation and its subsequent tautomerization to the imine form in solution is in agreement with the recent spectroscopic and NMR studies.
