Claudia Sala trained as a molecular microbiologist in the laboratory of Prof. Daniela Ghisotti, at the University of Milan (Italy), where she obtained her degree in Biological Sciences in 2000 and a PhD degree in Genetics and Molecular Biology in 2003. Her PhD thesis dealt with the transcriptional regulation of the furA and katG genes in mycobacteria in response to oxidative stress. In the framework of the EU FP6 ”New Medicines for Tuberculosis” (NM4TB) and FP7 “More Medicines for Tuberculosis” (MM4TB), she worked as a post-doctoral fellow in the laboratories of Prof. Stewart Cole, first at the Pasteur Institute in Paris, and then at the Ecole Polytechnique Fed´ erale´ de Lausanne, where she was subsequently promoted to senior scientist. She took active part in several research projects, including functional genomics and investigations on the M. tuberculosis Type VII Secretion System, and established the ChIP-Seq and RNA-Seq technologies in M. tuberculosis. She obtained the certificate of Biosafety Level 3 (BSL3) Safety Officer from the Swiss Confederation as well as the FESALA Category B and Category C licenses for performing and directing experiments involving animals. She was the recipient of the Swiss TB Award in 2010. She has recently moved to the Fondazione Toscana Life Sciences (TLS) in Siena, in the group led by Prof. Rino Rappuoli, and performs research on monoclonal antibodies and vaccine development. Her main interests include drug discovery against infectious diseases, vaccinology, host–pathogen interaction and biosafety. vii applied sciences Editorial Editorial on Special Issue “Tuberculosis Drug Discovery and Development 2019” Claudia Sala 1, Laurent Roberto Chiarelli

These mutants were sensitive to acid stress, antibiotic stress, alkylating stress, and oxidative stress indicating that mycothiol and mycothiol-dependent enzymes protect the mycobacterial cell against attack from various different types of stresses and toxic agents.

In order to ensure a proper functioning of cell replication and proteins and nucleic acids synthesis processes, folate metabolism rate is also increased in these cases. For this reason, folic acid antagonists have been used since their discovery to treat different kinds of microbial infections, taking advantage of this metabolic difference when compared with human cells. However, resistances to these compounds have emerged since then and only combined therapies are currently used in clinic. In addition, some of these compounds have been found to have an immunomodulatory behavior that allows clinicians using them as anti-inflammatory or immunosuppressive drugs. Therefore, the aim of this review is to provide an updated state-of-the-art on the use of antifolates as antibacterial and immunomodulating agents in the clinical setting, as well as to present their action mechanisms and currently investigated biomedical applications. Keywords: folic acid antagonists; antifolates; antibiotics; antibacterials; immunomodulation; sulfonamides; antimalarial 1.

  • Great South African Molecules: the Case for Mycothiol
    REVIEW ARTICLE C.M. Nkambule, 67 S. Afr. J. Chem., 2017, 70, 67–81, <http://journals.sabinet.co.za/sajchem/>. Great South African Molecules: The Case For Mycothiol Comfort M. Nkambule Department of Chemistry, Tshwane University of Technology, Pretoria, 0001, South Africa. Received 13 September 2016, revised 15 March 2017, accepted 17 March 2017. ABSTRACT South Africa has one of the oldest chemical societies in the world and has a long history of natural products, synthetic, and medici- nal chemistry yet the visibility of molecules discovered or synthesized in South Africa is very low. Is this because South African scientists are incapable of discovering influential and celebrated molecules, or is there inadequate publicity of such discoveries? Perspective profiles on the discovery and scope of research on ‘Great South African Molecules’ should be a good start to redress this state of affairs. One such molecule deserving publicity is the antioxidant mycothiol which is produced by mycobacteria. This is a molecule of interest not only because of its medicinal potential in the fight against tuberculosis, but also from synthetic methodology and enzyme inhibition studies. This review aims to illuminate the scope of research in mycothiol chemistry for the purpose of promoting multidisciplinary investigations related to this South African molecule.

  • Analysis of Mutations Leading to Para-Aminosalicylic Acid Resistance in Mycobacterium Tuberculosis
    www.nature.com/scientificreports OPEN Analysis of mutations leading to para-aminosalicylic acid resistance in Mycobacterium tuberculosis Received: 9 April 2019 Bharati Pandey1, Sonam Grover2, Jagdeep Kaur1 & Abhinav Grover3 Accepted: 31 July 2019 Thymidylate synthase A (ThyA) is the key enzyme involved in the folate pathway in Mycobacterium Published: xx xx xxxx tuberculosis. Mutation of key residues of ThyA enzyme which are involved in interaction with substrate 2′-deoxyuridine-5′-monophosphate (dUMP), cofactor 5,10-methylenetetrahydrofolate (MTHF), and catalytic site have caused para-aminosalicylic acid (PAS) resistance in TB patients. Focusing on R127L, L143P, C146R, L172P, A182P, and V261G mutations, including wild-type, we performed long molecular dynamics (MD) simulations in explicit solvent to investigate the molecular principles underlying PAS resistance due to missense mutations. We found that these mutations lead to (i) extensive changes in the dUMP and MTHF binding sites, (ii) weak interaction of ThyA enzyme with dUMP and MTHF by inducing conformational changes in the structure, (iii) loss of the hydrogen bond and other atomic interactions and (iv) enhanced movement of protein atoms indicated by principal component analysis (PCA). In this study, MD simulations framework has provided considerable insight into mutation induced conformational changes in the ThyA enzyme of Mycobacterium. Antimicrobial resistance (AMR) threatens the efective treatment of tuberculosis (TB) caused by the bacteria Mycobacterium tuberculosis (Mtb) and has become a serious threat to global public health1. In 2017, there were reports of 5,58000 new TB cases with resistance to rifampicin (frst line drug), of which 82% have developed multidrug-resistant tuberculosis (MDR-TB)2. AMR has been reported to be one of the top health threats globally, so there is an urgent need to proactively address the problem by identifying new drug targets and understanding the drug resistance mechanism3,4.

  • Revised Use-Function Classification (2007)
    INTERNATIONAL PROGRAMME ON CHEMICAL SAFETY IPCS INTOX Data Management System (INTOX DMS) Revised Use-Function Classification (2007) The Use-Function Classification is used in two places in the INTOX Data Management System: the Communication Record and the Agent/Product Record. The two records are linked: if there is an agent record for a Centre Agent that is the subject of a call, the appropriate Intended Use-Function can be selected automatically in the Communication Record. The Use-Function Classification is used when generating reports, both standard and customized, and for searching the case and agent databases. In particular, INTOX standard reports use the top level headings of the Intended Use-Functions that were selected for Centre Agents in the Communication Record (e.g. if an agent was classified as an Analgesic for Human Use in the Communication Record, it would be logged as a Pharmaceutical for Human Use in the report). The Use-Function classification is very important for ensuring harmonized data collection. In version 4.4 of the software, 5 new additions were made to the top levels of the classification provided with the system for the classification of organisms (items XIV to XVIII). This is a 'convenience' classification to facilitate searching of the Communications database. A taxonomic classification for organisms is provided within the INTOX DMS Agent Explorer. In May/June 2006 INTOX users were surveyed to find out whether they had made any changes to the Use-Function Classification. These changes were then discussed at the 4th and 5th Meetings of INTOX Users. Version 4.5 of the INTOX DMS includes the revised pesticides classification (shown in full below).
